Damaging Wind Gusts, Localized Severe Weather, Some Flooding All Possible Late Friday & Friday Night
We’re essentially in day-long rain for New England, though the intensity will vary from one part of the day to another. Steady but relatively light rain may taper to drizzle for Central and Southern New England by late afternoon and early evening, but as the instigating storm center approaches from the west, heavier rain and downpours seem sure to fire up again by late evening into the overnight. In fact, a surge of warm air with the rain will likely mean embedded thunderstorms, and localized severe thunderstorms producing small swaths of damaging wind can’t be ruled out. In addition and unrelated the thunderstorm potential, the Champlain Valley of Vermont will find strong, non-thunderstorm wind gusts Friday afternoon and evening that may exceed 50 mph and knock out power for some. Finally, the heavy rain Friday through Friday night will amount to between one and two inches, cauing potential flooding on New England’s rivers including the Sudbury in MA, Lower Connecticut in Connecticut, and NH/ME Pemigewasset, Saco, Presumpscot, Swift, Kennebec and Mattawamkeag Rivers. Most of the rain departs Central and Southern New England between 7 and 8 AM Saturday, and Northern New England shortly thereafter, leaving more clouds than sun, breezy conditions and perhaps a sprinkle with highs in the 50s to near 60 for many, though 40s in the mountains where a few snowflakes may fall in snow showers. Skies will clear Saturday night into Sunday morning before the next system races in, prompting scattered Sunday afternoon and evening showers that again may mix with snowflakes in the high terrain of particularly Western New England, with less chance of showers in the north. After a pleasant and bright Monday, most days next week feature an elevated chance of showers with temperatures near or slightly below normal for this time of the year in the exclusive First Alert 10-day forecast.
