Severe Storms Possible Today and Especially on Thursday, Much Cooler Weather for the Weekend!

The Storm Prediction Center (SPC) has placed much of the Washington Region under a Marginal Risk for Severe Thunderstorms this afternoon. 

Latest High-Resolution Guidance

Storm coverage this afternoon and evening looks to be around 30 to 50%, meaning most of us should remain dry (if these models are accurate).  Any storms that do fire late this afternoon and evening will be capable of producing damaging winds in excess of 60mph and hail.

There is a better chance for Severe thunderstorms on Thursday afternoon as a cold front begins to advance our way from Pennsylvania. Wind shear on Thursday afternoon will increase allowing for some storms to rotate.  Some storms on Thursday afternoon and evening could produce large hail, damaging winds in excess of 70mph and tornadoes.

Feeling More Like September

The cold front responsible for Thursday’s thunderstorms will usher in much cooler weather with lows dipping into the 50s and 60s and high temperatures struggling to reach the lower to middle 80s with low humidity. Friday through the Weekend look absolutely amazing!
