NH1 First Alert Weather: Bid Adieu to Summer, A Warm Welcome To Fall
NH1 Chief Meteorologist
All good things must come to an end I guess. It was quite a summer. I will miss it badly. As we reluctantly welcome fall and the cooler changes it brings, at least today will still have the feel of late summer warmth. Another mild day is expected with a light southwest flow in advance of a cold front which will be sagging into the north country this afternoon with some increasing cloudiness. Plenty of sunshine will dominate the day with highs ranging from 80-85 degrees. Cooler 70's across the north country on the cooler side of this boundary separating cooler air in Canada form the summer-like warmth in place across the east coast.
Thursday night the cold front gets pushed farther south into New Hampshire. A few showers are expected along the Canadian border. Scattered showers should reach southern areas towards Friday morning. Precipitation amounts should be light..generally a quarter inch or less since there will be a limited moisture to work with. Showers will be likely in the mountains Friday morning with the threat progressing southward and diminishing a bit during the day as the front slips southward.
Once the front is offshore, Cool high pressure will build in behind for Saturday through next Tuesday. Minimum temperatures during the period will range mainly from the 30s north to 40's to near 50 along the coast. High temperatures will be mainly in the 50s north to 60s south. Sunday will be the coolest day in the 60's and lwr 60's. Early Monday morning will have the best chance for frost to form in the north country and interior valleys. The threat of any significant precipitation appears to have to wait unti late next week. Plenty of sunshine heading into next week with highs moderating into the 60's to near 70 degrees by midweek.
