Today will feature the return of unsettled weather as our next storm system approaches from the west. Satellite imagery shows overcast skies across just about the entire region except for a small area near Augusta as of 6 AM. Clouds will finish overspreading the region in short order this morning and will remain in place for the rest of the day.
Precipitation associated with this system will arrive from SW to NE today, beginning a little before noon in SW NH before moving into far W ME around 2-3 PM and northeastern parts of the area by 5-6 PM. A few showers are possible before these times but that’s when the steadier precip should begin. Precipitation will fall as snow in the mountains, a mix of snow and sleet in the western/northern foothills, and rain elsewhere.
Colder air will filter south tonight as a secondary area of low pressure develops off Cape Cod. As a result, parts of the southeastern foothills and interior coastal plain that saw rain for most of today will switch over to sleet, and the NW foothills that saw sleet for most of today will switch over to snow. Even the coastline should get some flakes by tomorrow morning, though they shouldn’t accumulate much.
As far as accumulations go, here’s what the NWS is thinking for the event today/tomorrow. I think this looks pretty good for most spots though I’m not yet convinced that places like Camden and Belfast will pick up >2″. Overall, this won’t be a storm with major impacts and most of us should be staying at home anyways, so the greasy roads tomorrow morning will be far less of a bother than usual.
Temps today will be on the chillier side ranging from 45 near Augusta to 35 in the mountains of NH.
