We’ve got a little bit of everything coming this week, unseasonably warm air (again), a snowstorm (again), some rain (again).
The week starts off with high pressure sliding offshore, allowing mild weather to return to the region today, with high temperatures likely topping 50 in many areas. Clouds start to stream in by late in the day though as low pressure heads toward the region. That low pressure system will pass north and west of the area later Tuesday, with gusty southwest winds bringing in very warm conditions in for Tuesday into Wednesday, with many places possibly topping 60 degrees on Wednesday. There are some indications that the warm air may struggle to move into southern and central New Hampshire on Tuesday, possibly holding off until Tuesday night, which may allow for a little freezing rain Tuesday evening. With the warm air comes some rain later Tuesday and Tuesday night, into early Wednesday morning. The rain ends when a strong cold front moves through, with skies clearing in the afternoon. High pressure builds in for Thursday with dry and cold conditions.
Another storm system moves into the Ohio Valley before redeveloping off the Mid-Atlantic coastline for Thursday night and Friday. There are still plenty of variables to be determined, but with colder air in place, we’ll likely see some snow to start. How much snow, and whether it changes over to sleet, freezing rain, and/or rain are questions that we cannot answer yet, but there is the chance for several inches of snow for at least part of the region. High pressure builds back in next weekend with dry and chilly conditions.
