Timing Today’s Storms and Another Round Possible on Friday

The latest high-resolution North American Model (NAM) guidance indicates that a line of thunderstorms, will develop near the Blue Ridge mountains around 2pm, pushing north and east into the DC Area between 4 and 9pm (image below, courtesy PivotalWx).

The primary threat with the storms this afternoon continues to be damaging winds greater than 60 mph and small hail but an isolated tornado or two can’t be ruled out, especially if we get a few breaks of sunshine later this morning/early afternoon.

More Scattered Strong Thunderstorms Likely on Friday Afternoon

A potent disturbance will move through the DC Area on Friday afternoon firing off more scattered strong to severe thunderstorms.  The primary threat with these thunderstorms will be hail and damaging winds.

The Heat is on This Weekend

High pressure aloft will build across the Northeastern United States this weekend allowing for southwesterly winds at the surface and increasing heat and humidity.  Temperatures will soar into the lower to middle 90s this weekend with Sunday being the hottest day of the weekend.
