Strong Coastal Low Heads Northward Stormy Saturday Night

WHAT TO EXPECT

A 6 to 8 hour periods of stormy conditions with bursts of heavy rain and thunderstorms

Along the coast winds will pick up from the southeast at 20-35 mph with some higher gusts

Rainfall amounts of 2 to 3 inches in some places though there will be some variability. Flash Flooding is possible.

There could be one solid arm of thunderstorms that sweeps through areas from NYC eastward early Sunday morning that has the potential to produce severe weather.

If everything goes according to plan we should see a dry day for most of Saturday and some improvement during the day on Sunday but the period in between will be rocky for some. Low pressure is developing just off the South Carolina coast and moving northward. Before we get to that we have another winner of day with the satellite loop showing nothing but clear skies across the Northeast. This Friday will be another day of lots of sunshine low humidity and high temperatures into the 80s though it will be cooler at the shore once the sea breeze takes hold. No weather issues are forecast for tonight under a clear sky with lows in the 60s; 50s in the cool spots north and west of the coast. It has been another nice stretch of July weather that is coming to an end and we won’t see anything like this again anytime soon. The pattern goes to warm wet and humid overall starting this weekend and lasting on and off for at least the next 10 days.

EASTERN SATELLITE

REGIONAL RADAR

As far as Saturday into Sunday morning is concerned, looking for clouds to move up from south to north followed by rain moving up from South to north. The Southeast regional radar below shows the broad low center now as the radar echos rotate from east to west around the low center. There is no concentrated area of thunderstorms near the center so this system is not tropical in nature. Even if it were the resulting weather here would be about the same.

SOUTHEAST US RADAR

With the low tracking further to the west the risk for heavy rain has now spread westward as well into Eastern Pennsylvania and all of New Jersey. Rainfall amounts of 2 to 3 inches in some areas are forecast and depending on the thunderstorm strength some areas could get more so flash flooding is certainly possible. Along the coast winds will gust to gale force at times from the southeast. We are between major moon phases so at least that helps with coastal flooding. However there is one high tide Sunday morning that could be an issue if the southeast wind is still cranking at the time of high tide.

NAM RAINFALL FORECAST

Once the low moves to the north of your location weather conditions will start to improve. For Southern New Jersey south of 195 and Southeastern Pennsylvania with rain starting during the afternoon it could be mostly done by midnight or sooner as you go south. To the north in Northern New Jersey to NYC, Long Island & Southern New England storm conditions last into the early morning hours but it should be done (hopefully) by day break.

Weather conditions improve during Sunday though clearing of skies could be a bit elusive and another downpour or two could pop up in the afternoon in some scattered areas. Next week the pattern is a warm wet one with the chance for downpours and thunderstorms every day though it doesn’t rain all the time. There will be dry rain free stretches with temperatures in the 80s by day, upper 60s and lower 70s at night, and high humidity. UGH!
