NH1 Chief Meteorologist
Wednesday overall is going to be a pretty nice outdoor day for mid-October standards. A front pushed off the coast last night with drier air settling in over New Hampshire Wednesday morning with a westerly wind. Sunshine this morning will allow temps to climb into the lwr 60's by midday. Another weak cold front will approach during the afternoon with building clouds and the slight risk of an isolated shower with it's passage. Dry air will push back in Wednesday night with cooler air with lows dropping back into the 30's and 40's with clearing skies. Weak high pressure will provide for a mostly sunny seasonal Thursday with highs near 60.
Our next weather maker comes Thursday night-into Friday. A warm front approaches Thursday night bring increasing clouds and the risk fora few showers. An area of low pressure will be crossing Northern New England bring clouds and the risk of a few showers during the morning into the midday. This low will come with another cold front which pushes off the coast Friday with drying west winds and highs in the 50's near 60.
The charge of colder air begins on Saturday. It will generally be a breezy mix of sun and clouds with highs in the Lwr 50's for most of us, but the mountains will be a bit more interesting. Another weak cold front will be pushing through Saturday with building clouds, cold air advection, and breezy NW winds upsloping over the mountains. Temperatures will be falling from the 40's to the 30's with falling freezing levels Saturday afternoon through Sunday. Any available moisture with the orographic lift of wind rising up over the mountains may help to trigger scattered snow showers. There will be the potential for some accumulating snows above 3500 feet especially in the Greens and North facing slopes of the White Mountains.
Outside of the chance for some snow on the peaking foliage across the north country, the rest of us will see a few very chilly overnight! The coldest air so far with lows dropping to near 32 Saturday night. The combination of a departing to into the Canadian Maritimes and a building high to our west will keep a breezy NW wind from Canada directing the colder air into NH right through the weekend. Blustery weather can be expected with sunshine on Sunday and highs only in the 40's, but with the wind it will feel 35-40. Sunday night will be a hard freeze across the Granite state. The bus stop on Monday will feel like winter with lows in the 20's! High pressure will continue to supply the cold sunshine into Monday before milder SW winds quickly bring back milder air next week for a milder end to October.
