I know it's hard to believe this blog is about snow, but it snowed in Massachusetts on Mother's Day.
A mini nor'easter will form Monday night into Tuesday, bringing a chilly rain and even some wet snow, even though it's mid-May.
In this type of a set-up, most of us will see a chilly rain.
But in heavier bursts, the rain can flip to wet snow, as the column of air cools just enough. When the precipitation isn't as heavy, expect it to be drizzle or light rain.
This is exactly what this map is showing for Tuesday morning; see the blotches of blue indicating wet snow mixing in all the way to the coast.
It'll remain chilly Tuesday afternoon, with periods of rain (continued snow in the higher elevations), with highs only in the low 40s.
Most of the accumulation will be in the mountains of western Maine and New Hampshire. I'm forecasting 1 to 3 inches here, but it's possible some of the higher elevations (especially above 1,500) feet see more than that.
Outside of the mountains, coatings are possible, with most of the accumulation on the grass.
Cheers to spring in Maine...
