Flash Flood Watch Continues Low Pressure Moves Up Coast Tonight
Flash Flood Watch Continues
Low Pressure Moves Up Coast Tonight
Severe Weather Risk Friday
We are finally beginning to see the upper trough to the west moving eastward which has pivoted the rain out of Pennsylvania (for the most part) and moved it east so now the areas along and just inland of the coast will be in line for waves of downpours and thunderstorms. The first wave has already moved through this morning and there were some heavy downpours with this. In fact a weak rotation was indicated this morning on the radar in Westchester and Rockland counties. To the south right now there is a bit of a gap but we do see a cluster of downpours on the radar in Southern New Jersey moving northward.
The more important cluster of rain to focus on is the one that is now in Eastern North Carolina and Southeast Virginia that is moving northward and expanding somewhat. There is a weak low that has developed there and weather models are holding on to this low as it moves northward. This will be impacting New Jersey from south to north later this evening and reaching NYC and Long Island around 8pm and Southern New England and the Hudson Valley shortly afterwards.
LOCAL RADAR NEW YORK CITY
This low needs to be watched carefully as it could produce some very heavy rains as it moves northward. Since this morning’s wave of rain was capable of producing a weak rotation (possible tornado) I would not be shocked to see tonight’s low do the same. The HRRR model shows the low as it moves overhead around midnight.
Rainfall amounts will vary but somebody is going to get a couple of inches of rain out of this so the the Flash Flood threat continues.
The next 2 days look a bit better with clouds and some sunshine though there is the chance for a shower or thunderstorm late Thursday and again late Friday with highs in the 80s to near 90. In fact late Friday the Storm Prediction Center has us all at risk for severe thunderstorms which is unusual for them to be this bullish this early. We will discuss this later today. The weekend is actually looking ok with some sunshine and slightly lower humidity for both Saturday and Sunday with temperatures in the 80s and a minimal chance if at all for a downpour.
Please note that with regards to any tropical storms or hurricanes, should a storm be threatening, please consult your local National Weather Service office or your local government officials about what action you should be taking to protect life and property.
