Recreational Forecast

General:

Cloudy to start through Quebec. Showers elsewhere, tapering off in the Adirondacks and north of Rt. 2 by early afternoon, by mid-afternoon to RT 4, and by evening south of RT 4. Some clearing far north late in the day. Highs in the 70s. Northwest winds becoming north near 10 mph.

Brief:

Low pressure near Houlton, Maine this morning will drag a weak cold front into southern New England by mid-afternoon. As the wave continues towards an evening rendezvous with Cape Breton, Nova Scotia, a secondary cold front will sag southward over northern Vermont and New Hampshire late this afternoon. Drier air behind this second boundary will lead to gradual clearing overnight. High pressure sliding eastward across central Quebec will eventually link up with another moving east-northeast out of the upper Midwest during Sunday, and together, the two will bring relatively benign conditions to the region from then into early Tuesday. Areas near and south of the Massachusetts border will see fringe clouds and perhaps a stray shower from weak low pressure rippling along the first weak cold front, which is expected to stall a little south of Long Island for a time Sunday into early Monday. The next threat of widespread showers won’t arise until Tuesday night into Wednesday.

Winds:

Today: Northwest to north 5-15 mph. Tonight: North to northeast 5-10 mph. Sunday: Light and variable--tending towards east around 5 mph. On Lake Champlain, the National Weather Service forecast is for north wind 10-20 kts today, diminishing to 5-15 kts this evening and to 5-10 kts after midnight. Sunday, light and variable wind. Waves 1-2 feet through this evening, decreasing to around 1 foot after midnight, and to 1 foot or less on Sunday.
