Recreational Forecast

General:

Sun through some high clouds this morning, then developing afternoon clouds, with localized afternoon showers or thunderstorms through NY, just isolated east to the Green Mountains. Highs in the upper 70s to low 80s east of the Greens, in the 80s west. South winds increasing to 10 to 15 mph east of the Green Mountains, and 10 to 15 mph, gusting to 25 mph from the Green Mountains west.

Brief:

A mainly clear, moonlit night north gave areas a seasonably cool night, but a few clouds and a southerly wind in southern sections and the Champlain Valley have kept readings in the 60s, hinting at the warmth and humidity that is on the way. Weak high pressure is sneaking away to the northeast over the Canadian Maritimes this morning, allowing some high clouds to spill in from the northwest, while a developing southerly airflow draws moisture up ahead of a warm front over western NY and PA, helping to build some clouds this afternoon, with a few scattered showers or a thunderstorm popping up through NY and the St. Lawrence Valley, and maybe one or two drifting east to the Green Mountains later this afternoon. That front should drift east overnight into Wednesday, leading to a few localized showers or a thunderstorm overnight. As the front introduces very warm and humid air, a disturbance above us slides southeast tomorrow, triggering a rising chance of showers and thunderstorm, a storms potentially reaching severe levels, with strong winds, hail, and heavy rains, tending to fire up across northern sections midday and early afternoon, spreading southeast through the afternoon and early evening. Once that system heads east, a surge of hot, humid weather pushes in for Thursday and Friday. Temperatures will climb to the upper 80s and low 90s, along with a few stray afternoon showers and thunderstorms.
