Low Pressure Bringing Heavy Rain Saturday Into Sunday Downpours Late Sunday
Low Pressure Bringing Heavy Rain Saturday Into Sunday Downpours Late Sunday Severe Weather Risk
We hope everyone is enjoying the cloud free Friday as this is the last day we will see sunshine and relatively low humidity for quite a while. Skies on the satellite are nice and clear and we should be clear for most if not all of the night however some clouds to the south marking the northern fringe of low pressure in the Carolinas will start pushing into Southeastern Pennsylvania and Southern New Jersey overnight into Saturday morning.
For now nothing is in range of the regional radars but below we have the satellite and southeast radar loops. The satellite shows the broad non tropical circulation that represents low pressure. This broad low is slowly moving north northeastward hugging the Southeast coastline.

Reviewing the afternoon weather model series, I don’t see much to change. Models have been trending further west with the low center which cements the idea that the heaviest rain will be as you go west from the coast. It would seem 1 to 2 inches of rain is possible for most of the area but thunderstorms in the mix create variability.
We also have a severe weather risk that has been raised by the Storm Prediction Center with a marginal risk from Coastal New Jersey to New York City, Southern Connecticut to Long Island. These types of system have occasionally produced severe thunderstorms inside the bands of heavy rain.
Once the main low passes early Sunday morning we will be inside a deeply humid air mass with a strong upper low to the west. As disturbances rotate around scattered downpours and thunderstorms are possible Sunday afternoon and evening. In fact you can anticipate the chance for downpours every day next week under warm and humid conditions. It does not rain all the time. There will be dry periods.
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.
