GWC Weather Journal–June 5, 2016–Severe Weather Threat in NJ

Posted in GWC News, GWC Severe Weather Report at 10:57 pm by gmachos

Here is a timeline of weather conditions at Greg’s Weather Center in South Plainfield, New Jersey during the day on Sunday as a severe weather event unfolded across the Mid-Alantic.

7:21 AM–Woke up to see that the skies were quite dark.

8:30 AM–Stepped outside, and skies were overcast, but no rain yet.

10:00 AM–Saw the latest update from the Garden State Weather page that indicated moderate CAPE, some shear, but not much in the way of rising air or vertical development yet due to the cloud cover. Severe weather still possible.

11:00 AM–Checked out the Storm Prediction Center web site, which indicated that there is still an enhanced risk of severe weather for much of New Jersey late this afternoon and evening. SPC did point out that the ingredients for severe weather aren’t quite there yet due to cloud cover, but there could still be a significant rain and wind event.

12:00 PM–Rain came through earlier and I posted an article in the blog on both the severe weather threat for New Jersey on Sunday, and the newly formed Tropical Depression Three in the Gulf of Mexico. Rainfall came down fairly intensely in a short period of time. GWC WX Station rain gauge received 0.12 inches of rain.

1:35 PM–Just came back inside after going outside for a walk. Skies remained overcast, but no rain occurred during the walk. Air was very moist, thick, and humid. If there is some sun later this afternoon, things could get interesting.

2:04 PM–Just checked the local weather radar. Showers and storms currently in Central Pennsylvania with a narrow line of strong to severe storms leading the way near State College. The Weather Channel app indicates a large area of severe weather possible from New York to Georgia. Strong storms also possible from the Great Lakes to the Gulf Coast. TWC also indicates thunderstorm possible by 3:30 PM.

4:30 PM–Went outside to do a time lapse video, and noticed that the skies were becoming a bit more threatening. I also learned from the TWC app that a Severe Thunderstorm Watch was in effect for Eastern Pennsylvania and all of New Jersey until 10:00 PM. Made sure that all my electronic devices had enough power available. I also got my weather radio ready.

6:00 PM–Several severe thunderstorm warnings came through for Western New Jersey. Also took a look outside at the latest conditions and shot some video. Clouds definitely moving at a pretty good clip overhead, and continue to become more impressive despite the lack of sunshine today.

7:00 PM–Severe Thunderstorm Warning in effect for Middlesex County. Set up the GoPro Cam on the roof of the house to take some video footage of the storm coming through. A few moments later, at about 7:10 PM, the storm began to come through with heavy rains and really strong gusts of wind. You couldn’t see anything outside because the window was awash with water from the rain and wind.

8:06 PM–Checked data on the GWC WX Station. The storm that came through brought about 0.41 inches of rain with it and at a rainfall rate of 1.63 inches per hour. Winds were about 35 miles per hour. Checked the debris outside the house and there were no trees branches or wires down as well as no structural damage. Only debris from fallen leaves. High temperature today was only 75 degrees, but the dew point peaked at 73. Total rainfall so far for the day has been 0.53 inches for a total of 0.56 inches so far this month, and 13.61 inches so far for this year.

9:20 PM–Just came in from taking a walk around a portion of the town. Didn’t see any serious damage only a few decently sized tree branches by Sacred Heart School, and some more flimsy tree branches down in my neighborhood. Lot of leaves down. My guess that the winds in my neighborhood and surrounding areas on the north side of town had only 40 mile per hour winds.


Lots of Wild Weather To Talk About for Sunday

Much of Garden State Under Enhanced Risk for Severe Storms; TD #3 Forms in Southern Gulf

On Saturday, I had posted several articles on things going on in and around the country weather wise including a potential severe weather event for the Mid-Atlantic United States and a developing tropical disturbance in the Northwestern Caribbean. Well, since my posts on those two entities, things have changed quite a bit with more of New Jersey falling under an enhanced risk of severe weather on Sunday and a new depression forming in the Southern Gulf of Mexico.

First, let’s take a look at the current situation with the severe weather potential in the Mid-Atlantic. We could be looking at the possibility of a very significant if not historic weather situation in places like Virginia, Maryland, Delaware, Pennsylvania, and New Jersey. Now while I say that there is this potential for a significant severe weather episode for these locations, I must add that this is not set in stone, or at least yet. Over the last 24 hours, the Storm Prediction Center in Oklahoma has place a larger area under an enhanced risk of severe thunderstorms including some big east coast cities such as Philadelphia, Baltimore, and Washington D.C.

The latest outlook provided by the SPC this morning indicates that there will be several clusters of storms developing anywhere from Georgia to New York with the highest chance for severe weather in the Mid-Atlantic States. Currently, much of the eastern third of the country is under either a marginal or enhanced risk of severe weather. With dew points peaking in the upper 60s to low 70s during the day across the Mid-Atlantic, and an approaching cold front that has a nice shortwave brining additional energy behind it, there is a chance for severe thunderstorms to develop. However, the most recent model data from this morning is indicating that the threat might not be as significant.

The 12z, or 8:00 AM run of the HRRR indicated that while the CAPE levels, or measure of potential energy critical for storms was moderate and there could be a decent amount of shear available for rotation, there is not enough rising motion in the atmosphere since the lapse rates aren’t running as high. Part of the reason for this is the fact that there has been significant cloud cover on Sunday morning across much of the Mid-Atlantic. The translation of all of this is that not all the ingredients are there for really severe weather to develop. However, while there may not be all the classic ingredients for supercell thunderstorm and tornado development, there still could be enough upper level energy for significant straight line winds to come through along with heavy rains.

Things could change though. Another model run is expected around 18z or 2:00 PM this afternoon, and by that time, things could clear out enough following the warm front passage for the sun to come out and heat things up. If the sun is able to do that, its energy could provide the spark that could alter the atmosphere enough to bring about a more significant severe weather event. The bottom line is that it is very important to pay attention to the weather and sky conditions if you are out today. Also, make sure that you are keeping track of the weather through resources on your mobile phone, Internet, television and weather radio. Speaking of your weather radio, you also may want to make sure that you have plenty of backup power available for all your devices in the home.

Remember, this could be, and I emphasize could be a very dangerous weather situation developing. The ingredients for it may not be there right now, but that could rapidly change if certain things occur. The fact that the Storm Prediction Center has placed places such as New Jersey under an enhanced risk is very significant since it is very rare, and it should be taken seriously. Another important weather system that we are watching is the newly formed Tropical Depression Three in the Gulf of Mexico, which emerged late this morning after being a disturbance in the Caribbean for the past several days. Tropical Storm Warnings are already up for portions of Florida with the development of this depression.

The 2016 Atlantic Hurricane Season is already off to a busy start with three tropical cyclones now after this depression formed. Currently, Tropical Depression Three is located 120 miles to the Northwest of Cozumel, Mexico in the Yucatan Peninsula, or about 550 miles to the Southwest of Tampa, Florida. Maximum sustained winds are at 35 miles per hour with gusts close to tropical storm force. The minimum central pressure is down to 1005 millibars or 29.68 inches of Hg. TD Three is presently moving slowly to the north at 8 miles per hour, and that motion is expected to shift more to the northeast with an increase in forward momentum.

The latest track forecast is calling for the depression to be in the area of the Big Bend region of Florida sometime on Monday afternoon thanks to a push from a storm system currently over Texas. A Tropical Storm Warning is currently in effect for that region of the Sunshine State from Indian Pass to Englewood. There will be several impacts to worry about for residents that could be impacted by this system: Rain, Surge, Wind, and Tornadoes. Rainfall is the biggest threat with affected areas expected to receive anywhere from 3 to 5 inches with isolated locations getting up to 8 inches. Storm surge could range from anywhere between one to three feet above normal. Tropical storm force winds of over 40 miles per hour are anticipated in the areas closest to landfall on Monday afternoon, and with any landfalling system, you have the possibility of tornadoes.

The intensity forecast is calling for the depression to become Tropical Storm Colin within the next 12 to 24 hours. Peak intensity in terms of wind strength is expected within 72 hours as a moderate strength tropical storm with 60 mile per hour winds before coming a post tropical system. All residents of Florida’s Big Bend region as well as inland areas in the Central and Northeastern part of the state along with Southern Georgia need to closely monitor the progress of this developing system.


Rough Weather Possible for Sunday Around Jersey

Enhanced Risk of Severe Weather for Southern Jersey; Marginal Risk for Rest of Garden State

After a wet month of May with 3.40 inches of rain for places like GWC in South Plainfield, there has been a bit of a lull at the start of June for much of the Garden State. We are already into the fourth day of the new month, and so far, only 0.03 inches of rain has been received by the GWC rain gauge here in Northern Middlesex County. However, all of that is expected to change when a storm system comes through on Sunday afternoon and evening.

As of this morning, the Storm Prediction Center in Norman, Oklahoma, portions of the Garden State will be under an enhanced risk for severe weather while others will be under a marginal risk. Usually, portions of New Jersey never get placed under an enhanced risk. It is usually a pretty big deal when the Garden State gets put under a slight risk. So the fact that the SPC is calling for an Enhanced Risk of severe storms for parts of Southern Jersey is a really big deal.

According to the Day Two Outlook from the SPC, the area under the enhanced risk of severe weather include: Eastern Virginia, Northeast North Carolina, Maryland, Delaware, Southeastern Pennsylvania, and Southern New Jersey. Meanwhile, areas from Georgia into the Mid-Atlantic including the rest of Pennsylvania and New Jersey are under a slight risk. Conditions that could occur in all of these areas include: Damaging straight line winds, a few tornadoes, and severe hail. There also could be a great deal of rainfall.

The cause of all of this is a negatively titled shortwave that is currently moving through the Ohio Valley and helping to cause trouble in the Appalachians and Ohio River Region, which is presently under an enhanced risk by the SPC for Saturday. The shortwave will push east and help intensify a low pressure system coming out of Eastern Canada and provide a temperature and moisture contrast with the relatively warm and humid air in the Southeast and Mid-Atlantic to make things just enough unstable for severe weather in parts of Virginia, North Carolina, Maryland, Delaware, and New Jersey. Areas further north will get more isolated severe weather.

Looking at a recent forecast discussion and analysis from Garden State Weather, rainfall amounts could range from anywhere from a half inch or so in Atlantic City to close to over an inch and a half in Western Jersey near the Delaware River Valley. The rainfall could be a huge help though since despite the good amount of rain in May, there are many parts of the state that are still well below normal for this time of year. Middlesex County as a whole is averaging about 17.0 inches of rain so far this year, which is about an inch and a half below what it should be.

Other counties are much further below normal such as Monmouth, Somerset, Hunterdon, Warren, Morris, and Sussex, which all range from 2.5 to 4 inches below normal. Many of these places of key reservoirs such as Round Valley and Spruce Run in Hunterdon County or Manasquan Reservoir in Monmouth County. More urban counties such as Passaic, Bergen, Essex, Union and Hudson are also running several inches below normal for this time of year. All of this is in spite of the massive blizzard that took place toward the end of January.

So, try to enjoy the weekend, which could be rough at times, but on Sunday, keep an eye to the sky and watch for changing weather conditions, and stay tuned to local media and your NWS web site and social media pages for further developments with this potentially dangerous situation.


Bonnie Puts a Damper on Holiday Weekend Finale

Posted in Storm Track, GWC News, Tracking the Tropics at 9:04 pm by gmachos

2nd Named Storm of the 2016 Season Washes Away Beach Day for Many

The official start of the 2016 Atlantic Hurricane Season is still a couple of days away, and already we have two named storms on the board. Alex formed in January as a rare out of season storm, and over the Memorial Day holiday weekend, Bonnie emerged off the Southeastern coast of the United States as the second storm of the season.

Bonnie became a depression on Friday afternoon some 435 miles to the Southeast of Charleston, South Carolina. The emergence came after almost a full work week of speculation that something would emerge in the Western Atlantic. A disturbance spun up in the Bahamas earlier in the week, and the models were indicating that it would eventually come ashore as a tropical cyclone of some kind.

Despite the less than optimal conditions that are commonplace this time of year, the depression battled its way to become Tropical Storm Bonnie within 24 hours on late Saturday afternoon. Within six hours, Bonnie strengthened a bit more to have maximum sustained winds of 45 miles per hour (mph). The storm peaked at that point, and weakened back to a depression just before landfall at 8:45 AM EDT on Sunday morning.

The downgraded system came ashore to the east of Charleston, South Carolina in the Isle of Palms. Winds at that time were 35 mph with gusts up to 40 mph while the barometric pressure rose to 1009 millibars or 29.80 inches of Hg. Although it weakened, the depression still packed a wallop with torrential rains for much of South Carolina, and then it moved up toward the north and spread its rains into North Carolina and Virginia.

As the storm moved northward, it created instability throughout much of the Mid-Atlantic where potent showers and thunderstorms dumped heavy rains on places such as Washington, D.C., Baltimore, Philadelphia, and New York City. At Greg’s Weather Center in South Plainfield, New Jersey, there was 0.82 inches of rain during the overnight hours of Memorial Day. Much of the precipitation from Bonnie still laid to the south of GWC.

The remnants of Tropical Storm Bonnie is currently joining forces with a cold front pushing in from the west. Currently the front is producing heavy showers and thunderstorms in portions of Northeastern Pennsylvania and Northwestern New Jersey. Bands of showers lay to the south and east over coastal and Southern New Jersey thanks to the Northeast track of what’s left of Bonnie. All of this created unstable conditions throughout the holiday, and opened the possibility for severe weather here in the Garden State.

Earlier in the day on Monday, the Storm Prediction Center in Norman, Oklahoma put portions of the Northeast under a marginal risk for severe weather. The area included a slice of Northwestern New Jersey. Things should clear out for the start of the work week with cooler temperatures after a four day heat wave dominated the holiday weekend in New Jersey.

Heat Wave Kicks Off Unofficial Start of Summer in NJ

Posted in GWC News at 4:02 pm by gmachos

Four Straight Days of 90 Plus Degree Heat Signals Torrid Summer Ahead

The heat and humidity has returned to the Garden State with a vengeance in 2016. After three years of relatively cooler temperatures during the summer months, New Jersey was treated to a preview of what could be a torrid summer ahead with a heat spell that saw temperatures climb to 90 degrees and above for four consecutive days.

The peak was on Saturday when the Mercury climbed to 93 degrees at GWC in South Plainfield, the second warmest temperature during the month of May in the last five years. The warmest day in May recorded at GWC since 2011 occurred in 2013 when the thermometer rocketed up to 93.5 degrees. The heat started to become a factor last Wednesday, when the high temperature reached 88 degrees at GWC.

Then, on both Thursday and Friday, the mercury hit 91 degrees. Add to that heat indices that we well up into the upper 90s and over 100, and conditions felt much like that on the Fourth of July holiday weekend rather than Memorial Day Weekend. After Saturday’s high of 93 degrees with a heat index of 104, things cooled a bit on Sunday with the high temperature only getting up to 90 at GWC.

With the landfall of Tropical Depression Bonnie along the South Carolina coast Saturday night into early Sunday, and an approaching cold front, the heat wave will be snapped on Monday. Temperatures at GWC have only gotten up into the low 80s with the sun battling clouds all day today. The heat index was as high as 86 during the afternoon while the dew point climbed up to 72. So, although conditions cleared out after the overnight rain, there is still plenty of moisture around.

Speaking of moisture, the Storm Prediction Center in Norman, Oklahoma has put portions of New Jersey as well as parts of New York and New England under a marginal risk for severe weather today. With moisture from the remnants of Bonnie still to the south and a cold front approaching from the west, the ingredients are still there for some active weather this afternoon. Conditions have been very muggy all day with dew points in the lower 70s, and with the sun coming out in the early afternoon, there’s plenty of fuel being added to the fire.

Overnight, there were some heavy showers and thunderstorms that moved through portions of Central Jersey including Middlesex County. The rain gauge at GWC reported 0.82 inches of rain, which is the highest total for one day of rainfall so far this month. With the overnight rain, GWC has now tallied 3.40 inches of rain, which is the most rainfall since May 2012 when there was 3.56 inches. Three years ago, there was 3.26 inches at GWC. The combination of the recent heatwave, and the significant rainfall this month could be signals of a above normal summer in both temperature and rainfall.

With the decline of the most recent episode of the El Niño and the beginning of a new La Niña, we could be seeing the beginning stages of what could be a very hot summer with a lot of rain. Back in 2011 and 2012, conditions were well above normal in terms of temperature and rainfall here at GWC in South Plainfield, and those years were during La Niña episodes.


Coastal Low to Bring Some Chaos to Jersey and Mid-Atlantic

Posted in GWC News at 2:00 pm by gmachos

Storm Forecast to Dump Over an Inch of Rain on Saturday

Earlier this week, we discussed how recent rains helped slow down the dry weather that had dominated much of the first third of 2016. Since May 1st, Greg’s Weather Center has received 1.84 inches of rain for a year to date total of 11.49 inches. About a third of of May’s monthly rainfall came in one day. On the way though is a storm that will bring a good deal more than that.

A coastal low has been gaining steam over the last 24 to 36 hours, and it is forecast to move through the Mid-Atlantic including the Garden State starting on Saturday afternoon. It is expected to not only cause a big mess at the 2016 Preakness Stakes in Baltimore, but also bring between an inch to an inch and a half to the NYC metro area. Heavy rain is expected to produce a very sloppy field for the second leg of the Triple Crown.

At the beginning of the week, the forecast models indicated that the storm was going to move through the Mid-Atlantic and Northeast. The forecast held until Thursday when some of the models showed some doubt by indicating that the low would stay further to the south, and only bring heavy rainfall to South Jersey. Prospects changed on Friday when the models went back to their earlier prognostication, and brought the storm further north through New Jersey, NYC metro, and Long Island.

As of right now (1:49 PM EDT on Saturday afternoon, May 21st), skies are just overcast. No rain has fallen yet. Temperature has been steady for the past couple hours at 63 degrees. Humidity is at 58 percent for a dew point of 47. Barometer has been falling sharply at 30.02 inches of Hg. Winds are light. However, expect those conditions to change as the low pushes toward our region. The NWS Mount Holly office indicates the heaviest rain will fall between 2:00 and 5:00 PM this afternoon. Rainfall amounts during that time could be as high as six tenths of an inch.

The rain could linger around in the form of showers for Sunday, Monday, and Tuesday as well. The sun may not make a comeback until mid-week with temperatures climbing into the low 80s by Wednesday and Thursday.


Recent Rains Have Been Beneficial for Garden State

Posted in GWC News at 7:28 pm by gmachos

Rainfall Over Past Couple Weeks Has Slowed Down Dry Spell

A little over two weeks ago, I posted an article in the GWC and Hurricaneville blog about much needed soaking rains coming to New Jersey and the Mid-Atlantic. While those rains weren’t as significant as originally expected, it began two week period of beneficial rains that have helped to ease the drought concerns in New Jersey.

Since the very beginning of May, there has been 1.83 inches of rainfall here at GWC in South Plainfield. Prior to that, there had only been 0.86 inches of rain for the month of April at GWC, and 9.65 inches for the year. Now, the total rainfall for the year is at 11.48 inches. Although the recent rains were part of a gloomy and chilly weather pattern over the last 14 days, they proved to be very helpful.

A lot of this had to do with the fact that there had been a blocking pattern set up over much of the country. Over the last two weeks of April, there was a lot of nice weather with plenty of sun, and warmer temperatures across the Garden State and the rest of the Mid-Atlantic. Meanwhile, further west in the Plains, there were days and days of torrential rainfall in places such as Houston while further north near Dallas, there was severe weather in the form of tornadoes and hail.

The block shifted east eventually, but the weather wasn’t as severe. A week or so ago, there was nothing but clouds with some occasional light to moderate rainfall. There wasn’t any significant rainfall of over an inch, but one of the days last week, there was a decent rain of approximately two thirds of an inch. Now, these kind of blocking patterns are not unusual for this time of year, which is why Springtime is always a period of a variety of weather.

Some days will either give you a feeling that Spring has finally sprung, or summer is around the corner. Other days will make you ask yourself are we in May, or in the end of March or early April. Spring is a lot like fall in that it is a transitional season. They only difference is that Spring is on the way up from winter to summer while Fall is on the way down from summer to winter. Both seasons always have a great deal of variation in weather.


GWC Weather Journal–May 13 to May 14, 2016

Posted in GWC News at 11:16 am by gmachos

Here is a timeline of weather conditions at Greg’s Weather Center in South Plainfield, New Jersey over a period of 48 hours as the Mid-Atlantic got a one two punch from cold fronts.

May 13, 2016

8:48 AM–Stepped outside for a moment. Skies are overcast. No rain yet.

9:50 AM–Took a look at some things regarding the weather on Facebook. Joe Cioffi of FIOS1 and PIX11 indicated that there will be two cold fronts coming through the area over the next couple days. The first one is scheduled to come through on Friday afternoon, and originally this front was less likely to produce severe storms, but now the NAM model is indicating that it could be stronger. The second front is supposed to come through on Saturday afternoon after skies are forecasted to be sunny all day. The Weather Channel app indicated that rain is likely be 2:00 PM, and its radar showed a line of showers and storms in Central Pennsylvania. Looking at the latest conditions at GWC in South Plainfield, temperature is up to 64 degrees. Humidity is high at 87 percent. Barometer is falling at 29.86 inches of Hg. Winds are calm. Total rainfall so far this month at GWC is 1.44 inches while for the year, it is 11.09 inches.

Winds are still calm to light at GWC.

3:20 PM–Took another step outside to check the time lapse video and do a backyard weather report for Facebook page, and give another radar update. Outside, there was some sun, but it was shrouded in altostratus clouds giving a milky white effect to the sky. The leading edge of the showers and storms are moving through Eastern Pennsylvania. Rain and storms should be here at GWC in the next two hours or so. Temperature up to 74 degrees. Humidity is down to 49 percent for a dew point of 53. Barometer falling more rapidly at 29.61 inches of Hg. Winds are now picking up a bit to 5 to 10 mph.

4:52 PM–Just was outside. Skies are sunny, but there are clouds around. Checked the local radar, and saw that the line of showers and storms have moved into the western portions of Jersey with some strong cells near Rieglesville, Frenchtown, and Erwinna in Hunterdon County. The line is heading to the east. Temperature outside is up to 76 degrees with humidity down to 44 percent for a dew point of 52. Barometer continues to fall rapidly though at 29.57 inches of Hg. Winds are light around 5 mph.

GWC Weather Timeline–Saturday, April 30th to Monday, May 3rd, 2016

Posted in GWC News at 12:37 am by gmachos

Here is a timeline of weather conditions at Greg’s Weather Center in South Plainfield, New Jersey over a period of 48 hours while a storm system that brought much needed soaking rains came through.

April 30, 2016

10:50 AM–Stepped outside to set up the time lapse video. Skies are mostly overcast, but with some patches of blue sky. Feels a bit chilly outside.

1:00 PM–Returned from taking a walk and run. More sunshine and blue sky out than it was earlier.

4:00 PM–Have had a mix of sun and clouds during the course of the day at GWC in South Plainfield. Temperature up to 60 degrees with 51% humidity. Barometer steady at 30.16 inches of Hg. Winds are light. Soaking rain expected tomorrow.

Much Needed Soaking Rain on the Way for New Jersey

Posted in GWC News at 5:43 pm by gmachos

Rains Will Hopefully Ease the Drought Concerns in the Garden State

After a roller coaster ride of weather over the first two weeks of April that consisted of dramatic swings in temperature, and a variety of conditions from thunderstorms to high winds to snow, the Central Jersey area as well as the rest of the Garden State has enjoyed a good stretch of whether over the last half of April. There have been some hiccups along the way, but overall we’ve had it good.

Almost too good too. So far this April, the weather station at Greg’s Weather Center has also received a total of 0.86 inches of rain. For the year, there has only been about 9.65 inches of precipitation. Much of that occurred during the Blizzard of 2016 over the weekend of January 23rd. New Jersey is not alone either. Much of the Mid-Atlantic has been dry, and is in need of a good soaking rain.

Mother Nature is about to oblige. A storm system in the Midwest is heading east, and will begin to affect Pennsylvania, Virginia, and Maryland late Saturday night. New Jersey and the New York City metro area will begin to see the rain on Sunday morning. The National Weather Service office in Mount Holly, New Jersey indicates a 20 percent chance of precipitation on Saturday night going up to a 90 percent chance on Sunday, and a chance of lingering showers on Monday.

This storm system has had a history of producing some rough weather in the Plains, which has been pummeled by all kinds of severe weather this month. Oklahoma is cleaning up from tornadoes that passed through the area on Friday while Texas had its fair share of severe storms producing vivid lightning and lots of hail. While conditions have been mostly tranquil in the Garden State, they did get a bit interesting on Tuesday afternoon.

With a cold front diving into some relatively warm and humid air for this time of year, thunderstorms developed from Northeastern Pennsylvania and Southeastern New York down to Maryland and Delaware. The Storm Prediction Center in Norman, Oklahoma issued a Severe Thunderstorm Watch until 9:00 PM. These storms eventually moved southward and eastward into the Garden State causing the NWS office in Mount Holly to issue alerts and Special Weather Statements.

The heaviest weather came through Northern New Jersey, and moved across NYC and Long Island by 5:00 PM. Another strong storm came out of the Trenton and Hamilton area in Mercer County and moved eastward across Southern Middlesex, Monmouth, and Northern Burlington and Ocean County. More clusters of storms blazed a trail across Southern Jersey to near Atlantic City and Long Beach Island. Fortunately, GWC and much of Middlesex County was spared of these storms.

The close call is a harbinger of things to come as we move into the Severe Weather Season in New Jersey. Expect the conditions for severe weather to ramp up through the month of May and into June and July as the weather keeps getting warmer. However, this storm system and a potential nor’easter that the long range models are hinting at for late next week are reminders that it is still early Spring, and weather conditions will still tend to fluctuate back towards winter.
