Recreational Forecast

General:

Mostly sunny. Highs in the upper 60s to low 70s, some mid 60s northeast, and a few mid 70s in the warmer valleys west. Light winds becoming northwest near 10 mph.

Brief:

This morning starts mostly clear and cool, courtesy of high pressure sitting just above over us. A gentle northwest breeze will feed seasonably cool air over us, with afternoon readings in the low to mid 70s, with a few upper 60s northeast. This high should drift south through the day so that by evening, its clockwise circulation will turn our winds to the southwest, making for a much milder night. With the high positioned to our south Friday, and a cold front approaching from the north, an increasing westerly airflow will transport much warmer air into the area, reaching to near or above 80 for most locations. Our active, changeable weather pattern continues into the weekend, with some uncertainty as to the details of a cold front settling south Saturday. At first, it appears a few showers may reach northern areas later tomorrow, becoming likely through Quebec and along the international border Friday night into Saturday, while just a few showers or a thunderstorm are possible in southern sections. High pressure will be passing well to our north and build to our northeast Sunday. This may cause the front to stall over the region stretched from northwest to southeast. Elements of showers may track southeast along the front, while temperatures cool off in northeastern areas, milder to the southwest. Although the location of the front is uncertain, variable clouds, some breaks of sun, and a chance of showers continues Sunday into Memorial Day. The general trend will be for cooler temperatures, mostly 60s northeast, while in warms to the 70s west and south on the other side of the front.

Winds:

Winds light, becoming northwest 5 to 15 mph, turning to the south and southwest from the Green Mountains west, with waves on the open waters of Lake Champlain 1 to 2 feet, subsiding to 1 foot or less. Overnight, south to southwest winds near 10 mph, gusting to 20 mph from the Green Mountains west, becoming light in wind-sheltered valleys east, with waves on the open waters of Lake Champlain 1 to 2 feet. On Friday, winds becoming west 10 to 20 mph, gusting to 35 mph, with waves on the open waters of Lake Champlain 1 to 3 feet. The outlook for Saturday calls for winds becoming northwest near 10 mph.

Mountain:

The summits today will see partly to mostly sunny skies, with a light to moderate northwest wind decreasing, and seasonably cool temperatures. Friday will again enjoy mostly sunny skies south, developing afternoon clouds north, with an isolated shower in the far northern summits late. Look for a strong west wind bringing in warmer temperatures. The weekend outlook brings periods of clouds and a chance of showers, more likely north Friday night into Saturday, then more likely in the Adirondacks Saturday night and Sunday. Temperatures will cool, especially in the White Mountains and Northeast Kingdom. Light northwest winds Saturday, will become south to southeast on Sunday.
