Slight Risk of Severe Weather Later Today

Follow us on Twitter or on Facebook for more current updates this afternoon.

With a cool front entering into Western PA and working into our heat and humidity the risk of thunderstorms later today does exist. Radar is already showing some showers around in Central Pennsylvania and in the Lehigh Valley, generally lifting east and northeast early this morning.  With sun in a few spots in New Jersey and Delaware, the atmosphere will have some opportunity to destabilize through the morning hours, allowing for thunderstorm development to take place after midday.

Where we're all under a slight risk for severe weather today, the best chances for the strongest of storms probably reside in Delaware and South Jersey -- where the sun is shining this morning and probably holds serve through a good chunk of the morning.  The most instability will reside there -- as well as the most likely location for the warmest temperatures later on this morning and midday.   While the best chances for severe weather may reside over South Jersey and Delaware, the rest of us have a shot at getting scattered heavy thunderstorms this afternoon and evening.

The SPC (Storm Prediction Center) thinks the most likely culprit of any severe weather will be damaging wind.  Besides that, heavy rainfall is certainly possible with any thunderstorm that fires up later on as dew point values are at and above 70 this morning and the lower atmosphere is also moisture-rich.  Today's humidity will make up for yesterday's heat...and provide the potential for downpours in any thunderstorms you receive.
