Recreational Forecast

General:

Morning showers, mostly from the Adirondacks and Rt. 2 north tapering off. Cloudy, with some limited breaks of afternoon sun north, more intervals in southern valleys. Temperatures falling to the 40s to around 50 in the Adirondacks and St. Lawrence Valley, holding in the 50s elsewhere north, and upper 50s to mid 60s south. Winds southwest 10 to 15 mph, gusting to 20 mph, shifting to the west, then northwest.

Brief:

Scattered showers yesterday were much more effective at keeping temperatures cool, running in the 50s, though south of Laconia and Rt. 4, episodes of sun lifted readings into the upper 60s and low 70s. Last evening, skies cleared, permitting some dense fog in eastern areas, where it cooled to the 40s, while an approaching cold front brought more clouds, a mild southwest wind, and a band of showers west of the Green Mountains, keeping temperatures in the 50s. The front is working east across the region, attached to a storm now east of Montreal, and heading east through the St. Lawrence Valley. Showers and a few brief downpours are now lifting into Quebec and tapering off, though clouds will be stubborn, with only some limited breaks of sun through much of the area. As the front swings east, winds shift into the west, returning cooler air to the region. It will be most pronounced in northern NY and Quebec, with temperatures falling back into the 40s. Readings will hold in the 50s in the rest of the north, while more breaks of sun in southern valleys today will still lift readings there into the 60s. The colder air establishes itself this weekend, combined with low pressure in the upper atmosphere to keep lots of clouds in place, and squeeze out a few mountain rain or wet snow showers, while valleys, more so south, see some intervals of sunshine. It should be fairly chilly, with highs in the 40s to low 50s. Temperatures at night will depend on cloud cover, which means some chilly pockets may see some scattered frost or at least freezing temperatures at night. By Sunday night into Monday, a storm developing across the Midwest will head east, while high pressure remains to our north from Ontario into northwest Quebec, increasing our clouds, with a rising chance of rain, becoming likely in southern portions of VT and NH, possibly spreading north to the Quebec border. The timing remains uncertain this far out, but some chilly, wet weather looks like a good possibility early next week.

Winds:

At lower elevations, winds southwest 10 to 15 mph, gusting to 20 mph, shifting to the west, then northwest, with waves on the open waters of Lake Champlain 1 to 3 feet. Tonight, winds north to northwest near 10 mph, diminishing to light and variable outside the Champlain Valley and over the higher terrain, with waves on the open waters of Lake Champlain 1 to 2 feet. On Saturday, light north winds, 5 to 10 mph, with waves on the open waters of Lake Champlain near 1 foot. The outlook for Sunday calls for light west winds, 5 to 10 mph, with waves on the open waters of Lake Champlain near 1 foot.

Mountain:

For the mountains today, the summits will start mostly in the clouds, with a few showers north tapering off, then cloudy through the day. Temperatures will be falling, with moderate west winds decreasing in the afternoon. The weekend outlook calls for numerous clouds north, briefly in and out over the higher summits, with a few snow or rain showers, while the southern summits see clouds and a few breaks of sun. Temperatures will remain in the 20s and 30s, and light northwest winds will increase Saturday, remaining moderate from the northwest Sunday.
