The cold blast is moving into the Mid-Atlantic and will be with us over the next couple of days. As the core of the cold moves in, the upper trough may produce some snow showers or flurries on Wednesday. Temperatures will dip into the teens to near 20 Thursday and Friday mornings, with afternoon temperatures only in the 30s on Thursday.
Moderation for the weekend...
Surface high pressure will move over the area by Friday, and temperatures will moderate quickly this weekend. We should be well into the 50s during the afternoon and near 60 on Sunday.
Very warm for January early next week...
The big warm-up will continue early next week, with temperatures likely to reach the 60s Monday, Tuesday and probably at least into Wednesday. In fact, it's possible we could flirt with the 70-degree mark.
Changes beyond next week...
There are signs of significantly colder air coming back, potentially during the week of January 14th. I'm not sure this will be a prolonged spell though, as there appears to be a lack of blocking in the Atlantic, meaning the cold air can easily spill off the coast of North America. While there is a building ridge showing up in the model data over the eastern Pacific, the flow may eventually be quite zonal over the central and eastern U.S. Nonetheless, there should be at least a spell of colder weather for the middle of the month.
