18z Euro has precip onset just after 12z Thursday. A few hours of mix for the cities before changeover to rain. Surface temps start at 34 but cool to 32 during the morning hours before starting to warm up. Favored areas stay below freezing through 00z Friday. Temps start crashing by 9z Friday and a potential flip back over to frozen as it ends (ha, we do so well with that around here).
10:1 snowfall maps have the 2” line just SE of DC and 3” running through the city. While I do think we see a period of frozen precip, I don’t think we accumulate at all. I think the favored areas could see a few inches of sleet/snow. Just my guess at the moment.
