Mild and Increasingly Unsettled Today

Hello everyone!

Today will feature another day of warm weather as our latest storm moves towards the Saint Lawrence Valley. That said, we do have some cold air damming which will keep temps somewhat cooler especially in the Maine foothills. Any breaks of sun this morning will be quick to disappear behind thickening clouds midday. As high pressure slips farther east and winds shift more towards the south, the wedge of cold air currently pinned against the mountains will slowly retreat. It’s age-old wisdom that this retreating cold will depart slower than guidance expects but I do feel confident that folks east of I-95 in Maine and south of Laconia/Rochester NH will get above freezing today with highs rising as far as the low 50s in the CT Valley. The foothills and mountains should remain in the cold air through today with periods of freezing drizzle possible this afternoon.

The primary batch of precipitation will arrive this evening and will fall mostly in the form of rain except for the remaining cold air wedge centered around the Maine foothills. Freezing rain is expected here, though with heavier precip rates and temps creeping slowly closer to freezing I don’t see enough accretion to cause widespread power outage issues. By around midnight, a first frontal boundary will cross the area and mix out most of the remaining cold air. Temps will rise into the 40s and 50s across the area with perhaps a few holdout spots in the mid to upper 30s. That will set the stage for an extremely warm day tomorrow with southwest winds and patchy sunshine ahead of the storm’s cold front.
