A nice little snowstorm is on the way for SNE. As always, we will have to be watching the rain/snow line with this one. This line will be mighty important because just to the west and north of it, that is where the heaviest snowfall totals may be. Right now I have a good swath of 2-4" of snow for western New England. The "jackpot with this storm will be to the north and west of Boston by about 15 to 20 miles. A solid accumulation of 4-7" of heavy wet snow looks likely. The pink area is the wild card. The rain/snow line will be dancing around this region. We could see widely varying amounts of total snow. I will start as snow and then may transition to rain and then back to a heavy thumping snow on the backside of this system. Possible. For this area, I did not put an accumulation because we could wind up with nearly nothing or wind up with over a half a foot of wet snow. Its too close to call. SE of there, including Boston, it will be a brief period of snow, accumulating very lightly. Then it will transition to rain with temperatures in the mid - upper 30's at Logan and lower 40's on the Cape. Friday night we may see a flash freeze in areas that warm up enough to get some melting and rain during the storm. Temperatures will drop like a rock into the single digits and teens Friday night when the storm pulls into the Gulf of Maine where the northern part of that state will have blizzard conditions with 6-12"+ of powder.
More details on this storm later.
