The cooler air will be in place at dawn on Thursday with many areas starting the day off with temperatures in the 30's with clear calm conditions. High pressure will slide under and over us Thursday providing an absolutely brilliant and marvelous day to be outside and soak up the sun. Highs in the afternoon will climb into the Lwr 70's across southern New Hampshire.
Friday will start off great as well with morning sunshine, but the high will be pulling off the coast and high-mid level clouds will quickly increase during the afternoon. This will make for a grey appearance to the sky. Winds will be shifting to the SW with high temperatures in the afternoon climbing to 70-75 degrees.
A warm front will approach New England Friday night into early Saturday. The front will trigger a few showers for the early morning on Saturday with areas of drizzle lasting into the midday. Much of New Hampshire will remain on the cooler cloudy side of the front through the weekend with onshore winds persisting helping to trap in the low level cold. The warmer air to our South and West will continue to override this cool dome to make for considerable cloud cover through the weekend. Still, not all is lost here. The clouds should begin to lift and break a tad on Sunday with the stalled front ever so slowly shifting eastward. So western NH will have a chance of getting warmer, while the coast stays cool. That part of the forecast is a bit iffy.
High pressure over the Canadian maritimes will again strengthen and keep us dry through Monday, but also keep the cooler onshore winds in place for the start of the work week. Again, there is the chance for partly sunny skies...but just as much of a chance that the clouds could hold strong under an inversion with warm air above our heads. We'' see. It does not look all that bad. By Tuesday, a front will be approaching which will likely trigger a few more showers with another shot of breezy cool dry air for the midweek again.
