Discussion
A strong cold front will push through the region today and this morning’s warmth will be replaced by windy and colder conditions later in the day. The full brunt of this next cold air mass will arrive tonight and temperatures will tumble into the 20’s for overnight lows. On Saturday, cold high pressure will start the day nearby and low pressure will begin to pull out of the southern states and head towards the Mid-Atlantic coastline. This high pressure system will push off the coast by late Saturday and this will open up the door for precipitation to head our way from the southwest-to-northeast. The precipitation will likely arrive as snow late in the day or early Saturday night and then a wintry mix is likely tomorrow night. Snow accumulations of a coating to an inch or so are possible before any changeover in DC and points south and east and 1-3 inches of snow possible to the north and west. This will be a fast-moving, but potent system and all precipitation is will be over by very early Sunday morning. A major warm up will then take place in the early and middle parts of next week and temperatures will jump to 70+ degrees by Tuesday and Wednesday.
