Here is a time lapse video from the late afternoon at Sandy Hook on September 26, 2013. Conditions were very nice at North Beach on Sandy Hook. It was a bit more humid than it had been the previous few days in New Jersey. Clouds built up quite nicely during the early afternoon. Things did cool off though at the beach with more cirrocumulus clouds overhead.

Here is a time lapse video of weather conditions at Raritan Center in Edison on September 22, 2013. The first day of fall was met with a mix of sun and clouds after a cold front that brought anywhere from a half inch to an inch and a half of rain passed through.

GWC Severe Weather Outlook for Saturday Evening

Posted in GWC News, GWC Severe Weather Report at 5:51 pm by gmachos

Over the past couple days, conditions have been a bit warmer than normal for this time of year, and a tad muggy as well.  On Friday, the high temperature reached 78 degrees while the dew point peaked in the low 60s before dropping into the upper 40s.  On Saturday morning and early afternoon, those conditions continued with a bit of cloudiness and fog early on too boot.  However, there is a change on the way. 

A large and powerful cold front extending from Canada through the Eastern Great Lakes down into the Ohio and Mississippi Valleys is pushing eastward, and is expected to bring some heavy rain for a time on Saturday night.  The latest NWS forecast indicates anywhere from a half an inch to three quarters of an inch of rainfall for Northwestern Middlesex County as well as the rest of Central Jersey.  Further to the north and west in Northeastern Pennsylvania, there is a chance of up to two inches of rain there.

While the Storm Prediction Center in Norman, Oklahoma does concede that there is a risk of some thunderstorms, it adds that the possibility of severe weather is minimal.  The reason for that is because there is just not enough instability in the atmosphere to fuel the development of strong to severe thunderstorms.  There is a risk of cool air induced waterspouts over the Eastern Great Lakes according to an outlook given by the NWS office in Pittsburgh.  So, look for some heavy rain with some gusty winds as well as a few rumbles of thunder for a time this evening.

The timing of the storminess has varied during the day today.  This morning, there were indications on some local television outlets that the weather wouldn’t come through until sometime this evening between 8 PM and midnight.  Models indicated that it was going to come through later than that.  However, as of 7:00 AM this morning, the front was already moving into Western Pennsylvania. 

Nevertheless, the result of this approaching front will be a significant change just in time for the first day of fall.  The autumnal equinox is set to arrive at 4:00 PM on Sunday, and temperatures and humidity levels will be much cooler and drier by that time.  High temperature forecasted for Sunday is expected to be in the low 70s with some lingering showers.  Then, highs will only be in the upper 60s on Monday and Tuesday with clear and sunny skies.

On this day, what looks to be summer’s last stand ended with a bang as a couple waves of thunderstorms passed through ahead of a cold front that brought in a fall-like feel to the air in town as well as the rest of New Jersey. The storms brought 0.25 inches of rain followed by some showers overnight. It was the first day of measurable rain at GWC in over a week.

Ingrid Forms and Becomes 2nd Hurricane of 2013

Posted in Storm Track, Commentary, Storm Preparation, Storm Warning, Storm Safety, Tracking the Tropics at 6:39 pm by gmachos

Gabrielle and Humberto Dissipate, but Humberto Could Regenerate in a Couple Days

The Atlantic Tropics continue to get interesting as we now have our second hurricane of the season.  The other day, I had mentioned in the blog that Ingrid could be in the making.  Well, the storm not only came to fruition, and rapidly intensified into a minimal hurricane in the very warm waters of the Bay of Campeche region in the Gulf of Mexico.

Ingrid first became a depression on Thursday afternoon, and began its onslaught on Mexico with torrential rainfall.  Gaining more and more energy from the bath water of the Gulf, Ingrid strengthened more and became the ninth named storm of the season on Friday morning.  The intensification didn’t stop there either.  Thirty hours later, the storm grew into a hurricane.  Located some 195 miles to the East of Tuxpan Mexico and 275 miles to the Southeast of La Pesca, Mexico, Ingrid still continues off slowly to the north at 7 miles per hour.

As of the 4:00 PM CDT Advisory from the National Hurricane Center, maximum sustained winds with Ingrid are at 75 miles per hour with gusts in excess of 90 miles per hour.  Minimum central pressure has dropped to 987 millibars, or 29.15 inches of Hg (Mercury).  The Government of Mexico has issued a Hurricane Warning for the Mexican East Coast from Cabo Rojo to La Pesca, and a Tropical Storm Warning from north of La Pesca to Bahia Algodones and south of Cabo Rojo to Tuxpan.  All warnings issued south of Tuxpan to Cotzacoalos have been discontinued.

The big story with Ingrid is the forward motion.  The reason I say that is because of two things.  First and foremost, slow moving tropical systems means lots and lots of rainfall.  When there is torrential rainfall that goes on for long periods of time over this part of the world, you have to worry about life threatening floods and mudslides.  Right now, Ingrid is expected to produce around 15 inches of rain for portions of Eastern Mexico with some isolated areas getting over two feet of rain.  The other reason that the slow movement is critical is simply because of where Ingrid is located.

As mentioned earlier, Ingrid is still over very warm water in the Bay of Campeche region of the Gulf of Mexico.  With sea surface temperatures as high as 85 degrees coupled in with the fact that upper levels winds in this area are usually light, the ingredients are there for some significant, if not explosive development.  The latest discussion from the National Hurricane Center in Miami indicates that a mid-level ridge is expected to establish itself over the Southern U.S., and the clockwise flow around that ridge will help turn Ingrid into eastern Mexico.  However, forecast models diverge on the timing of all of this.

The NHC discussion points out that the GFS solution has Ingrid moving to shore the slowest, and making landfall in about 60 hours time.  The official NHC guidance indicates a landfall within 48 hours.  The 48 to 60 hour window is still a lot of time when you are talking about a tropical cyclone in a very conducive environment.  Remember, a little more than 48 hours ago, Ingrid wasn’t even on the map, and now it is a Category One Hurricane on the Saffir-Simpson Scale.  Another 48 to 60 hours in this very supportive environment could bring about even more strenghtening.  Right now, the NHC has Ingrid strengthening to an 85 mile per hour hurricane, but it is quite possible that the storm could reach Category Two or even Cat Three levels.

We’ll have to see how everything shakes out with Ingrid.  For now, residents along the East Mexican coast should complete the necessary preparations, take cover and evacuate if possible.  Residents in South Texas should monitor the progress of this storm.

The storms produced heavy rain, gusty winds, and frequent lightning in some spots of the county. South Plainfield, where GWC is located, had a strong thunderstorm move just to the north of it around lunch time, but then had another storm pass through just after sunset to produce a quarter of an inch of rain.
