Winter Storm Threat: January 21 (Only/Final Call)

More clipper fun for the Mid-Atlantic, only surface temperatures won’t be so wonderfully cold this time around. Marginal temperatures at the surface and around 900-925 mb as far north as I-70 (maybe even further north?) along with mostly light precipitation hurting snow chances. Most or all of the snow will also fall during daylight hours. One plus is it looks like areas from around D.C. northward will get below freezing tonight before the snow moves in, so the ground should still be nice and cold. Definitely more opportunity to end up lower than my forecast as opposed to higher. The Delmarva Peninsula and southern New Jersey could see heavier banding late in the event, which is kind of alluded to on my map with the 2-4″ stripe in southern New Jersey.

I wish I could wait until the 00z models came out for better forecast confidence, but this will have to do.
