Recreational Forecast

General:

Mostly cloudy. Scattered mountain snow and valley rain showers, becoming likely south and in the northern mountains. A trace to 2 inches of daytime accumulation, mainly over high terrain in the south. Highs in the mid to upper 30s in the hills, upper 30s to lower 40s in the valleys. North to northwest winds 5 to 10 mph.

Brief:

Scattered snow and rain showers slowly dried up yesterday, and temperatures even eased up a few degrees, along with periods of sun in southern NH, and limited breaks elsewhere in the afternoon. Periods of clouds kept us relatively mild overnight, and there might be a glimpse of sun this morning. But clouds will thicken and some periods of snow and rain showers are on their way today through tomorrow, a combination of a storm passing well to our south, and some energy and cold air in the upper atmosphere taking advantage of a northwest wind to squeeze out numerous snow showers for the mountains, and rather spotty activity in the valleys. An area of snow will head east through far southern sections this morning, perhaps a light coating over the higher terrain, while just a sprinkle or flurry dots the north. This afternoon, additional rain showers will develop, mixed with snow in the valleys, but mainly snow over the higher terrain, focused on the Adirondacks and Green Mountains. With colder air arriving tonight, and the northwest airflow continuing, much of the Adirondacks and western VT will see numerous snow showers, more scattered east, and tapering off in southeast VT and southern NH. That set-up lasts into tomorrow, which means a dusting to an inch is possible over the higher terrain east, and in the valleys west of the the crest of the Green Mountains, while the higher terrain totals some 3 to 6 inches. The last of the leftover snow and rain showers will taper off Friday night. Finally, increasing amounts of sunshine await us this weekend as large high pressure builds through Ontario south through the Great Lakes to Virginia, and then slowly slides over us Sunday through Tuesday. It will still be chilly on Saturday, then moderating temperatures Sunday into early next week, feeling much more like April.

Winds:

Winds today light, becoming northwest near 10 mph. Overnight, northwest winds 10 to 15 mph. On Friday, northwest winds 10 to 15 mph, gusting to 25 mph. The outlook for Saturday calls for northwest winds 10 to 15 mph, gusting to 25 mph.

Mountain:

The southern summits will be in the clouds again today, with snow this morning, and scattered to numerous snow showers this afternoon, producing light accumulations. Northern summits will start cloudy, the clouds lowering during this afternoon as snow showers increase. Light winds will increase from the north this afternoon, and temperatures remaining in the 20s. On Friday, expect little change – the summits will be mostly in the clouds, with numerous snow showers, moderate northwest winds, and remaining quite cold for April. The weekend outlook starts with variable clouds and sun Saturday, moderate northwest winds, and cold. For Sunday, more sunshine, lighter winds, and temperatures beginning to moderate closer to April figures.
