A strong cold front has pushed through the area this morning, and a cold airmass is moving in behind it. As a result, expect temps to fall through the day today starting off in the upper 20’s/mid 30’s north to south and ending up a little below 20 in the north and a little below 30 in the south by this evening. A little bit of moisture is moving up over the front this morning, resulting in areas of snow showers as seen on HD radar from weather.us. These snow showers will continue through the day today, with accumulations amounting to an inch or so by evening, when steadier snow will arrive. Steady snow will fall through the overnight hours as a change to mixed precipitation begins in the south. Look for a general 2-4″ of accumulation prior to this changeover with lighter amounts (1-2″) in southern NH and heavier amounts (4-6″) in the NE foothills/mountains.
The changeover to sleet and freezing rain will progress northward to the mountains tomorrow morning, resulting in a very slippery commute. Total ice accretion of 1/10 to 1/4″ is expected away from the Midcoast, where a change to rain is anticipated in the morning hours. Warm air won’t arrive for the rest of the area until heavy precipitation arrives tomorrow afternoon, with a line of embedded thunderstorms possible.
Precip moves out tomorrow evening.
