Unadulterated blue sky at last returned to all of New England but the Cape and Eastern Maine Monday morning, and while it marks a couple of days of fantastic weather sporting sunshine and mild days for most, there will be some subtle but important exceptions. The first exception comes Monday afternoon, as a cold and energetic upper level disturbance responsible for a tornado in Ottawa over the weekend and a pocket of snow in Quebec Monday morning drops south and sparks scattered thunderstorms in the North Country of New England. Thanks to the cold air aloft, these scattered storms will have the potential for not only cloud-to-ground lightning, but also hailstones and perhaps a few pockets of strong wind gusts from Northern VT to The Great Woods of NH to the Mountains of ME. Elsewhere, a steady breeze from the west will stave off a sea breeze, meaning beaches and interior, alike, will see high temperatures either side of 70 degrees Monday afternoon. Monday night, not only will scattered storms dissipate in the north, but skies will clear and the wind won’t quit, but it will ease, allowing temperatures to drop in our dry air, bottoming out in the 40s for most of us, with some 30s in sheltered valleys…likely only to produce frost in the far northern reaches of New England, but sure to make a chilly night for one and all. A quick rebound Tuesday will come with continued sunshine, though by Tuesday evening clouds will increase and some sprinkles late Tuesday evening should become scattered overnight showers, marking the leading edge to warmer, more humid air trying to nose back into New England. We’re unsure how far north the warmth will spread Wednesday but believe at least Southern New England should be able to break into the 70s or near 80…very unlikely in Northern New England. Thursday would likely continue the warmth but also continue an elevated chance of showers and thunder before another shot of delightful air, akin to the start of this week, arrives in time for next weekend in our exclusive First Alert 10-day forecast.
