Recreational Forecast

General:

***WINTER STORM WATCH SATURDAY INTO SUNDAY MORNING FOR NH, SOUTHERN-MOST VT, THE BERKSHIRES, AND ESSEX COUNTY VT***
Mostly cloudy. Scattered snow or rain showers in NY and the St. Lawrence Valley spreading east, mainly from Rt. 4 north, with a dusting to 2 inches over the high terrain. Highs in the upper 30s to mid 40s. Winds south to southwest near 10 mph east of the Green Mountains, and 10 to 15 mph, gusting to 25 mph from the Green Mountains west.

Brief:

Lots of sunshine yesterday, and a seasonably mild afternoon, with readings climbing to the upper 30s to mid 40s. Clouds were common through the Adirondacks, as well as the northern Champlain Valley and much of Quebec. The fair skies last evening permitted some views of Jupiter and Saturn getting closer in the southwest twilight, before clouds increased ahead of some unsettled weather moving in from Ontario and the Great Lakes. A few minor disturbances will bring some scattered rain or snow showers to northern areas today, enhanced a bit more tonight as a piece of energy in the upper atmosphere drives southeast through the Great Lakes. The rain showers will change to mostly snow showers north, perhaps a dusting to a few inches over the higher terrain. More importantly, the energy from this system will meet up with a developing storm now in the Gulf Coast states. This will strengthen the storm and help steer it through the Carolinas this evening, reaching the New Jersey coast tomorrow morning. Rain or snow is expected to develop south and spread northward, especially through eastern areas, with the potential for some significant accumulations. The details of this storm’s track and intensity will determine just how much snow falls, currently expected to be east of the Green Mountains, heaviest through central and northern NH, while only a few snow showers swirl around on gusty north winds through NY and the St. Lawrence Valley. Those same winds could result in considerable blowing and drifting snow east into Sunday morning. The storm races quickly northeast Sunday, with snow diminishing to snow showers, and much colder air follows Sunday night into early next week. A few snow showers might linger northeast into Sunday night, but mainly just a lot of clouds, with some periods of sun south Monday, and a bit more in the way of sunshine Tuesday.

Winds:

Winds today from the south to southwest near 10 mph east of the Green Mountains, and 10 to 15 mph, gusting to 25 mph from the Green Mountains west. Tonight, winds south to southwest near 10 mph, diminishing to light. On Saturday, light winds becoming north and increasing to 10 to 15 mph, gusting to 25 mph in the afternoon. Sunday’s outlook calls for northwest winds 10 to 15 mph, gusting 20 to 30 mph, strongest east.

Mountain:

Today calls for mostly cloudy skies, clouds lowering onto the northern summits, with snow showers in the Adirondacks, scattered through the northern Green Mountains, and a chance of afternoon snow showers in the southern Green and White Mountains. Moderate southwest winds decreasing, and temperatures about the same. The outlook for the weekend starts with clouds lowering south to north Saturday, and snow develops, mainly from the Green Mountains east. Northwest winds will diminish, and turn to the north and becoming stronger, while temperatures run a few degrees colder. Clouds Saturday night into Sunday with a chance of snow showers in the Adirondacks, and snow from the Green Mountains east tapering to snow showers. Winds turning to the northwest, moderate, while temperatures gradually fall through the day.
