Clayton Stiver's Weekend Winter Storm Forecast for NH
Tracking another storm system moving in from our southwest the next 24 hours to bring more accumulating snow to the Granite State. This will be a fairly quick moving system and because of that I don't expect snowfall totals to be too significant. Regardless, the potential is certainly there for slippery roads Sat. Night into Sunday Morning. Also, this snow looks to be a little more on the wet side, so it will be heavier. This does not bode well for a roof that already has a lot of snow on it and may be weak. Make sure to get that snow off your roof if there is a concern.
I expect snow to overspread NH mainly after 4pm Saturday. Light to moderate snow looks to go through the overnight and come to an end by sunrise Sunday. Temperatures will rise through the 20s Saturday PM and may actually climb above 32 after midnight into Sunday Morning. Because of this warming, snow may turn to rain for the Seacoast, and may mix with rain across the Merrimack Valley. I think 0.25" or less of rain can be expected.
Snowfall totals look to be on the order of 2"-4" for most with 4"-6" possible for portions of Grafton, Carroll, and Coos Counties, mainly across the White Mountains. For the immediate Seacoast, 1"-2" of snow is expected due to the mix or changeover to rain.
