As High pressure moves overhead Sunday morning it will be a chilly start to the day with a frost advisory in effect for Coos and northern Grafton counties until 7am. However, as the high begins to moves offshore for the afternoon it will warm quickly and turn into an absolutely gorgeous day with highs reaching into the 70s under a good deal of sunshine.
As winds become more southerly for Monday along with an approaching trough of Low pressure we will see a lot of clouds and a threat of showers moving in from the west during late Monday morning and into the afternoon/early evening. Nothing looks to be very heavy, but we will take whatever rainfall we can get. In fact, it looks like central and northern NH will get the most amount of rainfall. Warmer temperatures will follow for Tuesday through Thursday accompanied by climbing dewpoint readings which will also make it feel a little bit on the muggy side through the period. I also expect the region to remain dry through midweek, but as Thursday afternoon arrives there may be just enough instability in the air ahead of a weak frontal boundary combined with mid 80 degree heat that a scattered late day thunderstorm could pop up. Somewhat cooler air will then carry us into the next weekend.
Have a great weekend!
