The snow has started in many parts of the Mid-Atlantic, and as is on it's way to Southern Maryland. The storm looks like it's coming in faster, so the snow could start as early as 11am for some. As it becomes steadier and heavier, temperatures will drop and road conditions will go downhill. Treated highways and major roadways should fare decently into the early-evening or so with temperatures near or a little above freezing.
Confidence remains high that most, if not all, locations will get a minimum of around 10 inches by the time the storm finishes later in the day Saturday. There's a pretty good chance that some or many spots reach near or over 2 feet.
Governor Hogan's State of Emergency for Maryland took effect at 7am. Many schools, business, and governments have either closed for today (and the weekend) or will closing early today to be closed for the weekend.
