The air is about to change in New England as a cold front approaches from the northwest, but not before one more day of warm and humid conditions Thursday. In Northern New England, periodic showers and rain will drift from west to east through the day, eventually leading to some renewed scattered thunderstorms in Vermont and Western MA that may be severe in a few spots. Southern New England sees sun and clouds with temperatures rising well into the 80s, but this sets the stage for the scattered storms developing in Western New England to migrate east and perhaps hold together as at least scattered thunder from particularly the MA Turnpike northward Thursday late day and evening, even beyond dinnertime. Behind the scattered showers and thunder, the new air starts moving in almost immediately, but it won’t come rushing in – rather, Eastern and Southern New England may still feel humid first thing Friday before a westerly breeze lowers the dew point with enough dry air for plentiful sun and temperatures 80 to 85 for most of us, though a pop-up afternoon shower isn’t impossible in the northern mountains. Saturday, the air aloft turns quite chilly with a northern jet stream disturbance dropping south from Canada, and this will promote clusters of showers and perhaps even bursts of steadier rain in Northern New England where highs should be capped around 70, while Southern New England will find building clouds and the chance of an isolated shower midday to afternoon with an active breeze and highs closer to 80. Saturday’s disturbance keeps moving, so Sunday will be terrific regionwide and likely lead to a great start to the week next week before another chance of showers mounts toward midweek – to be determined whether that’s a standard scattered shower/thunderstorm potential, or perhaps a more organized rain storm that would keep temperatures cooler on Tuesday or Wednesday – we’ll keep you posted with our exclusive First Alert 10-day forecast.
