Recreational Forecast

General:

Areas of low clouds and fog this morning, lingering through the CT Valley through late morning, and remaining cloudy through NH, southeast VT, and MA, with a chance of a few showers this afternoon, mostly in southern NH. Highs in the upper 60s to mid 70s. Lots of sun west and north, highs in the upper 70s to low 80s. South winds 5 to 10 mph, becoming east near 10 mph across southern areas.

Brief:

We’re starting with a sticky summer morning, in spite of summer in its last days on the calendar. Low clouds and fog are particularly well established through eastern and southern areas, reflecting the extra moisture circulating in from the east, thanks to Hurricane Jose, about 200 miles east of North Carolina, and several hundred miles south of New England. Jose, a minimal hurricane, will drift north through tomorrow, while weakening, and then turning south on Thursday. This will limit any showers to eastern and southern areas later this afternoon, tonight, and ending Wednesday morning. Showers will become likely through southern NH, with a few light, scattered showers extending west to the Berkshires, and north into southwest VT, up to about Rt. 2 in eastern VT into NH. There is a weak cold front, beginning to stall through the St. Lawrence Valley, contributing to the warm, somewhat muggy conditions. It could help some low clouds form in northwestern sections later tonight into Wednesday morning, breaking for increasing sun midday and afternoon. After that Thursday into the weekend will see a warm, summer-time airmass settle right over us for the first weekend of Fall.

Winds:

Winds today becoming southerly across northern areas, and more easterly across the south, averaging 5 to 10 mph, gusting to 20 mph this morning on Lake Champlain, with waves on the open waters of Lake Champlain 1 to 2 feet, subsiding this afternoon. Overnight, winds will becoming northeast, then north 5 to 10 mph, with waves on the open waters of Lake Champlain near 1 foot. On Wednesday, winds increasing from the north 10 to 15 mph, gusting to 20 mph, with waves on the open waters of Lake Champlain 1 to 3 feet. Thursday's outlook calls for northeast winds 5 to 15 mph.

Mountain:

The Adirondacks and northern Green Mountains today will see sun mixed with clouds, while it becomes mostly cloudy through the southern Green Mountains, White Mountains and Berkshires. The southern summits will see a rising chance of showers, as well as increasing east winds, with little change in temperatures. Wednesday will start cloudy across the south, with any showers ending, and clouds gradually lifting and breaking. The northern summits will see increasing periods of sun. Moderate northeast winds will blow, but no significant change in temperatures is expected. Thursday’s outlook delivers lots of sunshine, light to moderate northeast winds, and temperatures still quite mild for September.
