Heavy Rain Threatens Friday followed by Decent Memorial Day Weekend

The upper-level low pressure system that has been stalled across the Tennessee Valley will finally begin to move northeastward crossing the DC region on Saturday morning before exiting on Saturday night.

Window for Steadiest Rainfall

A period of moderate to heavy rain is expected late Thursday night and continuing into Friday morning across the Washington Area. The latest North American Model (image courtesy Pivotal Weather) below shows the heavy rain bands moving into the DC Area on Friday morning and moving north of our area during the afternoon. Scattered thunderstorms may break out on Friday afternoon as the area of low pressure approaches, increasing the lapse rates in the atmosphere. Some thunderstorms on Friday afternoon will be capable of producing small hail.

Rainfall Totals

The heaviest rainfall is expected across the eastern slopes of the Blue Ridge Mountains where one to three inches of rain is possible.

Further east along the interstate 95 corridor a widespread inch of rain is expected with upwards of two inches falling where afternoon thunderstorms do form.

Memorial Day Weekend

Saturday will be the cloudiest day of the weekend with scattered showers and thunderstorms possible as the upper-level low pressure system exits our region.

Sunday will feature more clouds than sunshine with a cool, northeasterly breeze continuing off of the Atlantic ocean.

Memorial Day itself should feature partly sunny skies with temperatures climbing into the lower to middle 70s.

Wishing everyone a safe and Happy Memorial Day Weekend and thank you to all who have and continue to serve in the United States Military.
