Area highlighted by Storm Predicton Center for highest potential of severe thunderstorms (NOAA Storm Prediction Center)

From 11:51 p.m.: A cold front sagging south from the Northeast this afternoon to the northern mid-Atlantic tonight - along with strong upper level winds - promises to trigger strong to severe thunderstorms across this area.

The favored area for the most severe weather is from southern Pennsylvania to central Massachusetts where the front’s passage will encounter the strongest upper level winds and peak day time heating.

As NOAA’s Storm Prediction Center notes:

THE BEST CHANCE FOR ORGANIZED/SUSTAINED ACTIVITY WOULD APPEAR TO BE OVER SRN NY/NRN/ERN PA INTO SRN NEW ENGLAND AND NJ...WHERE SMALL BOWING STRUCTURES AND POSSIBLY AN EMBEDDED SUPERCELL OR TWO WITH DAMAGING WIND MAY OCCUR IN ADDITION TO MARGINALLY SEVERE HAIL.


Probability of damaging winds within 25 miles of a given point. These are highest ofer southern New England but extend into the D.C. metro region (NOAA Storm Prediction Center)

Any storms that develop - given large amounts of instability (very hot temperatures and high moisture content locally) - are likely to produce very heavy rain and dangerous lightning. And we cannot rule out the possibility of some damaging winds in some of the storms.

We will keep you apprised of storm development and any watches or warnings issued.
