Next Storm System Arrives Tonight

Hello everyone!

Our next storm system will arrive from the west tonight as low pressure moves towards the Adirondacks. Expect any morning breaks of sun to quickly transition to overcast skies this afternoon. Precip will arrive in western NH this evening before moving into Maine a little before midnight. Precip will start as snow for everyone away from the NH Seacoast. Snow will then change to rain along the coast south of Portland (east of the Turnpike) and along the Midcoast (SE of Route 1) with minimal accumulations there. 1-3″ will be on the ground around midnight for most areas, so be very careful if you’re travelling back from NYE festivities!

After midnight, snow will change over to mixed precip in NH, with the mix line creeping east during the early morning hours. I am very skeptical of surface warmth making it very far inland, but areas east of the Turnpike as well as Southern NH should see a change to rain by sunrise tomorrow morning. Other areas will see a mix of sleet and freezing rain, while only the far NW mountains (near Sugarloaf) hold onto all snow. Total accumulations will range from nothing on the NH seacoast to 1-3″ for the rest of the coast, 3-6″ for areas just inland, 4-8″ for the foothills, and 6-10″ for the mountains. These amounts will be highest in NE parts of each zone (less mix) and lower in SW parts of each zone (more sleet/ice vs pure snow).

High temps today will range from 25 in the north to 35 in the south.
