A chilly weekend is on the way (in December? Say it ain’t so!), but could there be some snow too?

High pressure will slowly build in, with dry and cold conditions into Saturday. Winds will remain gusty tonight and Friday morning, with wind chills dropping into the single numbers and below zero, so keep that in mind if you’ll be heading outside for any reason. Later Saturday clouds will start to stream back in as we turn our eyes to an area of low pressure developing near the Mid-Atlantic coast, and an upper-level trough of low pressure moving eastward from the Great Lakes.

The big question that we can’t answer yet is “where does that area of low pressure go?” Some models keep it well to the south, with little to no impact for our area, maybe a little snow near the South Coast and Cape Cod. Some bring it farther north, with light snow as far north as the Mass Pike, maybe even a little farther north than that. If it is far enough north, this could result in some rain across parts of the Outer Cape and Islands. If this weren’t the first accumulating snow for many areas south of Boston it wouldn’t be a big deal, and in fact, it really isn’t a big deal. Right now, we expect some light snow and snow showers to develop before daybreak Sunday, continuing off and on through the day, ending towards evening. Obviously this is highly uncertain, and we’ll likely issue a special blog post on Saturday if things look different. We expect most of the accumulating snow south of Route 2, likely south of the Mass Pike. The highest accumulations will likely be across parts of southeastern Massachusetts and Rhode Island, but even there, we’re thinking 2-4 inches at most. Breezy and colder weather returns behind the system on Monday.

Thursday night: Becoming clear, windy. Low 14-21.
Friday: Sunshine and a few clouds, breezy through midday. High 28-35.
Friday night: Clear skies, some clouds start to filter in late at night. Low 15-22.

Saturday night: Cloudy, light snow or snow showers developing before daybreak, mainly south of the Mass Pike. Low 20-27.
Sunday: Cloudy with occasional light snow or snow showers, mainly south of Route 2. Snow might mix with a little rain on the Outer Cape. High 27-34.
Sunday night: Snow showers end in the evening, clearing overnight, becoming breezy. Low 11-18.
Monday: Morning sunshine with afternoon clouds, breezy. High 22-29.
