Wednesday brought a midweek warm-up under plenty of sunshine and some windy conditions with gusts nearing 30mph. As the dome of high pressure continues to slide southward over the open Atlantic waters, we’ll see the warm, slightly humid air clash with the cooler, Canadian air allowing for a few downpours and a few rumbles of thunder. This approaching cold front, the boundary between clashing air masses, will slowly sag into Northern New England tonight, delivering evening showers to Northern Vermont and overnight showers with patchy fog to the rest of the North Country.
As the cold front, representing a new shot of cool air, trudges southward Thursday, it’s likely to bring little more than increased clouds and a sprinkle. Plus, the cool air lags far enough behind the front that most of us will still reach near 80 degrees.
By Friday, slow cooling will be underway – 70s for most – with another cold front approaching, in an attempt to deliver a reinforcing shot of fall air. The interesting twist is this front will probably slow very close to us, or even turn around…meaning warm air will not relent, and a warmer-than-normal pattern continues into early next week. That said, upper level disturbances will still help to focus some showers from time to time this Columbus Day weekend, particularly on Sunday and Monday. Early next week, our chance of rain remains elevated as we watch some tropical moisture from the Gulf of Mexico to see just how much of that rainfall reaches this far north.
