Warnings Already Issued For Parts Of Jersey; T-Storm Watch In Effect Until 10:00 PM
The thunderstorm threat is back again. After thunderstorms fizzled out in the late afternoon and early evening across Jersey, another threat has developed for Saturday. Strong thunderstorms developed this morning over Western New York near the Eastern Great Lakes. Storms also developed across Long Island during the course of the morning, but nothing had occurred yet in New Jersey.
However, during the lunch hour, things started to heat up in the Garden State. Clouds started to build in, and severe thunderstorms developed. Both of the storm cells were over parts of Central Jersey. One caused a Severe Thunderstorm Warning to be issued for Mercer, Western Monmouth, Southwestern Middlesex, and Southwestern Somerset County until 2:00 PM. The other was for Southern Monmouth and Northern Ocean County until 1:45 PM. These storms had the capability to produce hail and winds in excess of 60 miles per hour.
While these storms have pushed offshore, there are still potential problems. The Storm Prediction Center in Norman, Oklahoma issued a Severe Thunderstorm Watch for the entire state until 10:00 PM. Here in Northern Middlesex County, there is a good deal of overcast, and a bit of a breeze out of the east. Conditions remain humid, but it is a bit cool out for this time of day. Temperature in South Plainfield is 77 degrees while the dew point is up to 74 degrees. If the sun comes out though, severe weather is very likely since the heating of the sun will act as a catalyst for the instability that is already in place.
The locations within the watch area can expect hail up to 1.5 inches in diameter, winds in excess of 70 miles per hour, and dangerous lightning. Looking at the latest radar, a lot of thunderstorm activity could be seen over Southeastern New York in counties such as Orange, Rockland, and Putnam. Meanwhile, back in the Garden State, there are a few pockets of strong thunderstorms including Sussex County, Warren County, Morris County, and Burlington County. Nothing threatening Middlesex County yet. Keep an eye to the sky this afternoon and evening.

It also set the stage for the more severe thunderstorm in the evening by leaving behind plenty of moisture and humidity for the sun to work with. The evening storm was part of a long line of severe storms that produced two inch hail, winds in excess of 60 to 80 miles per hour, and even tornadoes in Pennsylvania, New York, and New Jersey.

The National Weather Service in Mount Holly has given a 30 to 40 percent chance of thunderstorms developing late this afternoon into the evening. Strong to severe thunderstorms already have been rumbling through Central and Eastern Pennsylvania.

The severe weather here in Northwestern Middlesex County was the third round of storms during the day on Thursday. There was a brief thundershower in the early morning followed by a stronger storm that brought a downpour by late morning. The rainfall in the morning set the stage for the severe weather in the afternoon creating a great deal of moisture and instability for the sun to play with when it came out in the early afternoon.
Temperatures that were in the low to mid 70s at mid-morning climbed into the low 90s by the afternoon. Dew points went up from 69 in the morning to 77 by the late afternoon.

Strong thunderstorms fed off of the heat and humidity as they began their jaunt from Eastern Ohio and Western Pennsylvania during the mid-afternoon.
Moving at a rate of 50 miles per hour, these storms had the capability of producing hail that was two inches in diameter and 80 mile per hour winds along with dangerous cloud to ground lightning.

A Tornado Watch was issued for Northeastern Pennsylvania by late afternoon.
The hardest hit areas in Jersey from this derecho like system were in Hunterdon, Somerset, Middlesex, and Monmouth County.

According to the Storm Prediction Center, there were reports of 3 tornadoes, 419 of straight line winds, and 38 of hail from the severe weather on Thursday. Two of those three reports of twisters came from Elmira, New York. Three reports of hail came from Pennsylvania while one came from New York. Ten reports of high winds came from New Jersey including one from Plainfield for downed wires on Park Avenue, and then another from Edison for downed trees. Three people were injured in Rockaway Township in Morris County when a downed tree fell on a house there.
Hot, humid, and unsettled weather is expected through the weekend with temperatures reaching the mid to upper 80s with a chance of thunderstorms in the afternoon and evening from Saturday to Tuesday.
Long Line Of Strong Storms Bearing Down On New Jersey
With another day of intense heat and humidity, the Garden State is primed for severe weather as we head into the evening on Thursday. Earlier this morning, two waves of thunderstorms passed through without much in the way of rain, but it created a very hot and humid atmosphere, which is providing the spark for an intense line of thunderstorms moving through Central and Eastern Pennsylvania.
Temperatures were in the upper 60s to low 70s this morning, but after the two waves of storms came through, the sun emerged to heat up an already unstable atmosphere. The temperature went up to 74 by 9:00 AM, 83 by 12:00 PM, and then a high of 91.1 during the mid-afternoon. The dew point soared up to 77 degrees and combined with the temperature, made it feel like it was 104 degrees outside.
The Storm Prediction Center in Norman, Oklahoma has placed Northwestern Middlesex County as well as the rest of the Garden State under a Severe Thunderstorm Watch. Already some of those areas are under a Severe Thunderstorm Warning. Further to the Northwest in Northeastern Pennsylvania, near Scranton, there is a Tornado Watch. What we have here is the makings of another derecho, but this one is further north than the one that pummeled South Jersey about a month or so ago. These storms are capable of producing dangerous lightning, hail 2 inches in diameter along with 80 mile per hour winds.
The watch area stretches some 65 miles to the north and south of a line from 25 miles North-Northeast of Groton Connecticut to 65 miles Northwest of Wilmington, Delaware. Skies are already darkening here in Northwestern Middlesex County. Take cover, and
