NH1 First Alert Weather: Cooler weather for now
NH1 Chief Meteorologist
A low sits up in the Canadian maritimes and continues to wrap in a cooler flow from Canada with a breezy WNW wind today with gusts to 20-30 mph. A mix of some sun and building clouds will be in place today with the cooler air aloft with a trough in place across the Northeast. Highs will be in the mid-upper 60's in SNH, with cooler 50's and lwr 60's in the mountains and lakes.
Upslope rain and snow showers will continue Thursday morning in the mountains where clouds will dominate all day. Thursday will be a dry day, with a less of a risk for a pop up shower or storm. Scattered rain of snow showers off and on in the mountains for much of the day into Thursday night thanks to the low cloud deck.
The northwest flow aloft will continue Friday with lighter winds and highs still in the 60's. Clouds remain in the mountains with partly sunny skies downslope from the mountains in the lower elevations.
A weak upper level ridge will shift east just in time for the weekend. High pressure at the surfaces south of New England will wrap in a warmer WSW winds Saturday with highs returning temperatures to a more classic summer time feel with highs in the 70's and even a few lwr 80's in southern New Hampshire. Highs will be near 70-74 at the beach with sunny to partly sunny skies.
Clouds will be increasing Saturday afternoon with the risk of a few showers developing late Saturday night. A cold front will push through with the best chance of showers this weekend Saturday night through Sunday morning. Once the front is offshore, drying NW winds on the back side will help to improve Sunday's weather as the day progresses, especially by afternoon with highs near 70.
A very strong clipper digs southeast later in the weekend and causes an upper low to develop somewhere over northern New England...models differ on location. Either way it will be deep and broad so this will mean another round of cooler temperatures and unsettled weather for the star of the week. This upper low will sit over the Canadian Maritimes. Breezy NW winds along with building diurnal clouds from the cooler air aloft will give Monday and Tuesday and chance of a shower or two during the peak heating of the day with cooler than normal temps remaining in the 60's and Lwr 70's. By midweek, the upper low should be lifting out with temps back into the 70's near 80 by Wednesday.
