We’ve got a rather turbulent week coming up across the region.
High pressure will be in control to start the week, with a mostly dry Monday, but a storm system is on the way. Low pressure will cross the Great Lakes and head up the St. Lawrence Valley while weakening. Meanwhile, a secondary area of low pressure will develop off the Mid-Atlantic coast and head eastward. We’ll be in between the two, which means some light to perhaps moderate snow developing Monday night continuing into Tuesday. The Tuesday morning commute is going to be rough, so plan accordingly. As temperatures rise to near or above freezing, we may see a change to rain, especially across southeastern Massachusetts, possibly into the Boston area. So, the afternoon commute may not be as bad, especially south of Boston. The snow winds down during the evening. Despite earlier model predictions and internet hype, this will NOT be a big storm. In general, most of us will see 2-5″ of accumulation, perhaps a little less along the coast, perhaps a little more near the hills from northwestern Rhode Island into central Massachusetts and southwestern New Hampshire.

Wednesday starts off dry, but another weak disturbance moves through late in the day with a few rain or snow showers possible. Another system quickly follows for Thursday, but this one looks warmer, as it will pass north of the region, so some rain showers are expected, maybe some freezing rain as you head up into central New Hampshire. That system moves offshore Thursday evening, then high pressure builds in, but it doesn’t hang around for too long. Yet another system quickly follows for late Friday into Saturday. There’s still plenty of uncertainty with this one, but it looks to pass near or just south of the region, so more snow is possible, or perhaps a mix of snow, sleet, and rain. Obviously, we’ll have a better idea of what this storm will bring (we hope), but the time we get around to our Weekend Outlook on Thursday. Yet another weak disturbance may bring in some snow showers Saturday night and early Sunday before high pressure builds back in.
