Brief:

Milder temperatures, moisture, and frozen ground – the ingredients for a slippery morning. In this case, bridges do NOT freeze first, because last week’s deep freeze has refrigerated road surfaces, as well as parking lots and walkways. Fortunately, most of the precipitation has moved out, and temperatures should climb into the 40s in most locations this afternoon, and only drop a few degrees tonight. A storm well to our north will pull any showers or freezing rain to our north by midday. Cold high pressure from yesterday remains in the western Atlantic, steering milder air north, and forcing a storm now west of the Great Lakes to our west and north through tomorrow morning. It means a steadier rain arriving later tonight, with the melting snow and rain potentially breaking up some river ice, leading to the threat of flooding. What follows bears close watching, as arctic high pressure builds to our north, and yet another storm lifts northeast. However, this storm will be deflected to our south, and the shallow, leading edge of the cold will work south into the region. Being shallow, it may easily settle into areas west and north of the mountains, as well as feed south through the Champlain Valley. East and south of the spine of the Green and White Mountains, the cold air may be less pronounced, resulting in a wide variance in precipitation types and amounts. Northern and western areas could see significant amounts of sleet, freezing rain, and snow, while southern-most locations deal with more rain. A Winter Storm Watch has been posted for VT and northern NY Friday night through Saturday, with additional watches and advisories likely as the details become more certain. With the potential for hazardous driving conditions, possible power outages, ice jams, and localized flooding, keep checking for the latest information.

Winds:

Winds today from the south to southwest 10 to 15 mph east of the Green Mountains, and 10 to 20 mph, gusting to 30 mph from the Green Mountains west. Winds overnight from the south to southwest 10 to 15 mph east of the Green Mountains, and 10 to 25 mph, gusting to 35 mph from the Green Mountains west, and over the higher terrain east. On Friday, south to southwest 10 to 15 mph east of the Green Mountains, and 10 to 20 mph, gusting to 30 mph from the Green Mountains west, shifting to the northwest late. Saturday’s outlook calls for north to northeast winds 10 to 15 mph, gusting to 25 mph.

Mountain:

Any wintry mix will change to rain showers across the summits this morning, and generally taper midday and afternoon, with summits starting in the clouds, the clouds lifting in the afternoon except in the Presidential Range in NH. Temperatures will climb into the 40s on strong southwest winds. Friday brings clouds and rain to obscure the mountains, possibly mixing with sleet or freezing rain in the Adirondacks by evening. Temperatures in the 40s, starting to fall later in the day, and strong southwest winds, shifting to the northwest and decreasing later in the day. The weekend outlook starts with snow or sleet in the Adirondacks, changing to snow, freezing rain changing to sleet or snow in the northern Green and White Mountains, and rain in the southern mountains, possibly changing to sleet and freezing rain in the afternoon. Temperatures will fall into the teens in the north, and from the low 40s to the upper 20s south, with temperatures colder at lower elevations. Winds will shift to the north and northeast. Sunday is expected to keep periods of clouds and a few snow showers over the northern summits, otherwise becoming partly sunny. Mid-winter cold returns, with single digits to low teens, and moderate north winds.
