Cooler and Cloudier Today

Hello everyone!

Our run of extraordinarily mild weather is beginning to come to an end today as we get some cooler marine air ahead of a big cold front that will cross the region tomorrow and usher in seasonably cool air from Canada. Satellite imagery this morning shows low clouds locked in across most of the area with a few clear spots in southern and western NH. This is due to a backdoor cold front draped near the NH/ME border separating cool marine air to the east from warmer continental air to the west. Today’s weather will be driven primarily by this feature.

East of the front in Maine and eastern NH, look for thick clouds to remain stuck overhead throughout the day. Light south-southeasterly breezes will keep temps in the upper 50s to low 60s, and patches of drizzle/light rain are possible.

West of the front in western NH, skies will feature a mix of sun and clouds with light south-southwesterly breezes keeping the mild weather rolling. High temps will top out in the upper 60s to low 70s, and the better shot for a shower or two will come in the late afternoon as some instability develops due to the unseasonably warm and humid airmass.

A quick peek at the weekend forecast shows two rounds of showers on tap tomorrow morning and evening as a storm tracks up the Saint Lawrence Valley. Between the system’s warm and cold fronts, breezy southerly winds will bring one last day of mild weather before colder air moves in behind the front for Sunday.
