NH1 Chief Meteorologist - NH1.com
Beautiful sunshine starts the day Thursday with high pressure to our west. A few clouds could start the day across SE NH, but skies will be rapidly clearing with wall to wall sunshine. A good day for the sunglasses and sunscreen with highs mostly in the 70's. Winds will be light from the north, but likely turn onshore for an afternoon sea breeze to keep it cooler at the coast in the Lwr 70's.
High to mid level clouds will be on the increase Friday ahead of an approaching warm front. High pressure will shift south of new England and wrap in a warmer Southerly wind with highs in the Lwr 80's with sunny to partly sunny skies. As a low tracks towards the Great Lakes, this warm front will bring more clouds Friday night with the risk of a few scattered showers for the early morning on Saturday.
This warm front will stall over New Hampshire, but most of the region will climb into the warm and humid sector behind the warm front by Saturday afternoon. Highs will climb to near 80. Breaks of sun will push temps into the Lwr 80's but also set up the potential for stronger t'storms. Instability will rise ahead of a cold front which will arrive in western New England later in the day and could be a trigger for more scattered showers and storms to fire up along this front. Some storms may become strong-severe along this front and instability axis. The best chance of any strong storms will be in western New Hampshire late in the day and the rest of the state by Saturday night with the chance of a few localized downpours.
This cold front will wash out over us Saturday night and push off the coast Sunday. A warm muggy feel will remain for the weekend with clouds and sun Sunday with highs near 80-85 and the risk for a pop up shower or storm during the heating of the day. Another cold front approaches again late on Monday. This will be a better focus for more widespread showers and storms and again the potential for some severe weather late Monday, Monday night. By Tuesday and Wednesday, drier air is expected along with a warm flow of air from the mid west will help to keep temps in the 80's with more in the way for sunshine for the middle of next week.
