Squall Line this Evening Ahead of ‘Arctic Blast’

The image above (courtesy Tropical Tidbits) is from the latest North American High-Resolution forecast model. Notice the yellow line of heavy rain moving through the DC Region between 00z (8pm) and 02z (10pm) this evening. This represents the actual cold front which will be accompanied by brief torrential rain and winds gusting in excess of 45 to 50mph.

High temperatures on Saturday will range from the low to middle 40s in our western zones to the upper 40s in downtown Washington… more typical of mid January than early May.


Wind Chills will be even worse on Saturday as gusty winds make the temperature feel like it is in the 20s and 30s during the afternoon.

Some snow will accumulate during the next 48 hours from West Virginia to Maine.

Mothers Day will feature mostly sunny skies with high temperatures in the upper 50s to near 60 degrees. The windy conditions will have subsided by Saturday evening, making Sunday fairly nice outside.

The week ahead should feature a nice break from the rain with several dry days before rain chances increase as we approach next weekend.
