When will it snow in Mass., NH? Thanksgiving storm outlook – NBC Boston

Our pattern has reversed and we now have a “cornucopia” of erratic weather and precipitation types in our Thanksgiving outlook.

This weekend

A strong low pressure system continues to meander over New England on Friday and through the weekend. By late Saturday into Sunday, the low will be over the Canadian Maritimes, but it will still affect our weather pattern.

On Friday, our scattered rain will develop into more even rain for the evening commute and overnight. This rain is spinning in from the southeast and offshore, giving Boston another chance to receive about half an inch of precipitation through Saturday morning.

On Saturday afternoon, the showers will linger and then slowly subside in the evening. We dry off for southern New England on Sunday with sunshine and a fresh northwest breeze. Highs will be in the 40s both days this weekend.

Meanwhile, in the mountains we see snow showers all weekend. Higher elevations will get several inches of a snow mix through Sunday, with Sunday’s snow developing more from upslope snowfall than the low pressure system.

Tuesday storm

This one is a minor storm late Monday into Tuesday. A low pressure system is tracking over the Great Lakes and will remain far enough north of us to be a rain event on Tuesday.

Only the far northern mountains could see some snowfall Tuesday evening as colder air returns. We dry off on Wednesday. Highs will remain in the 40s to low 50s through Thanksgiving.

Thanksgiving snowstorm?

This one is robust enough that we are seeing some strong signals for a storm moving through. Rain with elevation driven snow late Thursday into Friday.

The track is still very much up in the air, as is the timing, and we can’t pin down details, but there may be travel delays on those days. As for snowfall, our probability of 3 inches of snow in 24 hours is pretty strong for this time frame. Again, the snow lies on higher ground.
