Afternoon Forecast, Thursday, September 10, 2026

0:00From the Fairbank's Museum in St. John's Murray, welcome to this afternoon edition of the Isle of Sky Forecast. A cold front is sweeping through from our northwest this afternoon, serving as more of a source of gusty winds rather than a bearer of cooler air. That will come tomorrow behind a secondary front that might squeeze out a sprinkle over the northern mountains this evening in the interim. So contributing to the relatively warm temperatures today was a very warm start with last night's lows largely in the low to mid 60s and some locations seeing rising temperatures late last night, such as at Burlington, where the thermometer rose to 70 degrees by 6 a.m. This afternoon, even behind the front, gusty winds are maintaining quite summer-like temperatures, especially in the valleys of southeastern Vermont and southern New Hampshire, where many locations have made it above 80 degrees. These winds are unfortunately generating a lot of evaporation, which isn't helping

1:03the drought or near drought conditions that have developed over portions of our forecast area. At normally dry conditions or moderate drought are indicated in New Hampshire. In Vermont, moderate drought is indicated in much of the northeast kingdom, plus Orange County, and roughly the western third of Washington County, with the rest of Washington County shown to be abnormally dry, as is all of LaMoyle, as well as Eastern Franklin County in Vermont. But on the flip side, a good bit of help came from the showers that fell yesterday and last night. In Vermont, almost half an inch fell at the Barrymont Pilar airport, a little over half an inch in Windsor and here in St. John'sbury. Sixth-tenth of an inch fell in Starksboro, around three-quarters of an inch at Westford, Jericho and South Burlington, almost an inch at Inusburg Falls and again near Stowe, and a little over an inch at North Hartland and again at the Rutland Airport. In terms of additional showers, there might be a couple of sprinkles this evening, as the

2:06secondary cold front comes in from our northwest. By far, the bigger impact from this next front will be considerably cooler temperatures tomorrow, with many or all Northern Valley locations stuck in the 60s, just by a good deal of sunshine. And there will still be a bit of an northwest breeze tomorrow contributing to the feeling of autumn in the air. Cool high pressure will be responsible and already will be starting to drift off to our east by tomorrow night, which will probably help to stave off any frost even in the colder hollows. By Saturday, the breeze will again become suddenly making Saturday comfortably warm and probably the nicest of the next several days by most standards. On Sunday, we will be somewhat wedged in between two weather systems. A warm front will be grazing southern areas while a separate system sends a cold front in from our northwest. This setup will generally bring scattered showers and with some steadier rain possible in the south, especially on Sunday morning, depending on how close the southern system gets.

3:11After that, another round of cool high pressure will build in from the Great Lakes for Monday. In the short-term forecast, summary this afternoon partly to most of the sunny highs in the upper 70s to lower 80s in the south end of the Champlain and Northern Connecticut valleys, mid to upper 70s elsewhere north, west winds 10 to 20 miles now are Augusting to 30. Tonight, clouds variable early, decreasing late chance of an early sprinkle in the northern mountains, lows from the mid 40s to around 50, except low to mid 50s far south and in the Champlain valley. For Friday, partly to most of the sunny, valley highs in the mid to upper 60s, north upper 60s to mid 70s in the south, northwest winds gusting to 20 miles now are east of the greens. Clear skies on Friday night with areas of valley fog developing, lows mainly in the 40s, some lower 50s in the Champlain valley end, mid to upper 30s in northern cold hollows. For Saturday, areas of valley fog in the morning, otherwise mostly sunny and warmer, highs

4:12in the low to mid 70s, warmer valleys in the mid to upper 70s, winds on Saturday from the south at 5 to 10 miles now are in areas east of the green mountains, 5 to 15 miles now are in areas west of the greens and gusting to 25 in the Champlain valley.
