Weekend Outlook: February 19-22, 2021

The weekend starts off with some snow, and it looks like it might end with some snow as well, for at least part of the region.

The steadiest snow has been confined to the South Coast thus far. Loop provided by Weathertap.

We’ve got a series of weak low pressure areas passing south of the region tonight into Friday night. This will produce some occasional light snow well into Friday night, possibly lingering into Saturday morning for east-coastal areas, thanks to northeast winds behind the last of the storm systems. Along the South Coast, some sleet or rain may mix in for a while tonight and early Friday, keeping accumulations down a bit. For most of the region, this will be a general 3-6 inch snowfall, a little less along the South Coast, perhaps a little more across eastern and southeastern Massachusetts. Considering the snow is falling over the span of 24-36 hours, it will be an annoyance, but not that big of a deal.

While we may see some sunshine develop on Saturday behind the storm, an upper-level low pressure area will cross the Northeast, generating more clouds and perhaps a few snow showers. These shouldn’t produce much additional accumulation. We’ll clear out for Saturday night and Sunday as high pressure builds in. Temperatures will be on the chilly side, but nothing that extraordinary for the latter half of February.

By Monday, the next storm system moves toward the region. With cold air in place, we’ll have snow developing across much of the region, but a change to rain seems likely, at least south and east of Interstate 95, possibly even farther inland. How far inland will depend on whether a secondary storm system develops to our south or not, which the models don’t agree on at this point. Either way, this system will be a fast-mover, and won’t contain a lot of precipitation, so even in places where it doesn’t change to rain, we’re not expected a lot of snow, possibly a few inches.
