The summits will enjoy another day of mainly sunny skies, a few clouds this afternoon, along with light west winds, and warmer temperatures. Friday calls for variable clouds and sun, more clouds north in the afternoon. Light to moderate west to northwest winds, and little change in temperatures. The weekend outlook brings clouds lowering across the summits from north to south Saturday as showers increase, potentially with a few thunderstorms. Moderate southwest winds, becoming west late and decreasing, while showers begin to cool the warm temperatures. On Sunday, the summits will be obscured in clouds and showers to start, with the showers north tapering off, and cloud bases lifting a bit. Light to moderate northwest winds will continue to cool temperatures, steady or falling through the day.

Winds today light, becoming west to southwest near 10 mph, with waves on the open waters of Lake Champlain building to 1 to 2 feet.

Detailed Discussion

June really outdid itself yesterday – blue skies, only decorated by a few tiny tufts of clouds, temperatures warming to the upper 70s and low 80s, yet with very low humidity, and light winds – a spectacular day for many outdoor plans. High pressure that drifted from the Great Lakes to the Blue Ridge and Smokey Mountains of the central Appalachians this morning deserves a round of applause, though I sense an encore coming, with another mainly sunny, warm day on the way today. It’s milder this morning, which means we’ll gain another few to several degrees, reaching the 80s, and perhaps nudging 90 along the warmest valley floors. At the same time, with the high drifting a bit more south today, we turn our attention to a slow-moving cold front to our north through central Ontario and Quebec, starting to push south on Friday. This will add some clouds this afternoon and tonight, though it should stay generally fair. As the front gets closer on Friday, more periods of clouds will arrive, though it remains seasonably warm. The timing of the front doesn’t bode well for weekend outdoor plans, as showers along the front reach far northern areas late Friday night, and continue to work south Saturday. There should still be plenty of warm air ahead of the front, enough to support some thunderstorms, even a few strong storms, featuring some gusty winds and heavy downpours. The front will take its time settling south, though the timing is less than certain. Showers are most likely Saturday night, but a faster-paced front could end the showers in northern areas by Sunday afternoon, while a slower front might give southern areas more dry hours Saturday, but then linger with numerous showers Sunday. Latest guidance is leaning toward a slower front, which means southern areas could see a little sun Saturday morning before the showers arrive there in the afternoon. It also gives more time for the atmosphere to warm, boosting the potential for thunderstorms. Once the front progress to the south Sunday night, the showers will end, followed by seasonable weather for early next week, with lows in the upper 40s and 50s, and highs in the 70s. Another spell of warmer weather could develop toward mid-week.
