Today will feature relatively calm conditions ahead of our first regionally significant winter storm of the season. Expect any morning sunshine in northeastern parts of the area to be promptly replaced by clouds in the net couple hours. Temps will be on the colder side, ranging from 20 in the north to 30 along the coast. Snow will move in overnight, peaking in intensity early tomorrow morning.
A general 4-8″ is likely a good bet for most of the area, with slightly lower 2-4″ amounts east of route 1 south of Portland and south of Route 1 east of Brunswick where rain will mix in tomorrow morning. Slightly higher 8-12″ amounts are expected in the mountains, especially east-facing slopes that get some upslope enhancement.
Snow moves out of the area midday tomorrow.
