DAYS 1-5 (FEBRUARY 8-12)
High pressure will be the dominant player this weekend, which will be cold and dry for the most part. But each day will have a possible yet minor exception. First, we’re still in the pressure gradient this morning between the approaching high and departing low that impacted the region yesterday, and there will be just enough low level moisture to pop some cumulus clouds and a remote risk that one of them may grow just enough to produce an isolated snow flurry today, mainly north of Boston, but the risk is tiny and fleeting. And on Sunday, the fragmented remains of what was originally being watched for a possible snowstorm will bring some cloudiness into the region and a remote risk of a few stray snowflakes, this time favoring areas south and west of Boston. Despite the weekend break we’re not out of the woods for weather action, and before this 5 day period is up we’ll have a low pressure area travel eastward but pass north of here later Monday, dragging a warm front / cold front combo through, with a risk of some interior snow/sleet and coastal rain from the warm front in the early hours of Monday, with rain showers from the cold front during the day Monday as we get a shot of milder air post warm front / pre cold front. The cold front will settle just to the south of the region Tuesday at which time a wave of low pressure will be moving eastward along it, passing just south of New England. This won’t be a strong storm until it gets well beyond this area but it may spread a shield of rain/mix into parts of southern New England for several hours Tuesday. A little slower evolution and it may end up as a complete miss. So there will be a tad bit of fine-tuning to do with that one. High pressure moves in with dry and chilly weather for Tuesday night into Wednesday, but we may already be seeing a rapid advance of cloudiness during Wednesday ahead of the next weather system…

DAYS 6-10 (FEBRUARY 13-17)
Active pattern with a couple of opportunities for significant winter weather events mainly early and again later in the period. Not sure how these play out yet but we’ll be in that battle zone between building cold to the north and continued mild weather to the south. There is quite a bit of potential for extended unsettled weather which may include frozen precipitation.
DAYS 11-15 (FEBRUARY 18-22)
One or two more opportunities here for messy winter weather but far too early for details.
