Meteorologist Danielle Noyes has your detailed New England forecast for the next 24 hours which includes pockets of rain, snow and ice depending on where you are across New England.
A dynamic pattern will dominate the U.S. over the next several days, with multiple impactful weather systems affecting the nation. In the West, a significant atmospheric river is delivering heavy precipitation. Southern and central California, the Sierra Nevada, the Great Basin, and the Central Rockies are experiencing torrential rainfall and mountain snow, with localized flooding and landslides possible in areas of steep terrain. Snow totals in the Sierra Nevada could reach 1-3 feet above 8,000 feet, tapering off by Wednesday. Snow is also blanketing portions of the Intermountain West and Colorado Rockies.
Across the Great Lakes and Northeast, lake-effect snow is ongoing, with localized heavy snow downwind of Lakes Superior, Michigan, Erie, and Ontario. Totals of 4-8 inches are possible, especially in favored snowbelt areas like the Tug Hill Plateau.
Arctic air is poised to surge into the Northern Plains by midweek, with temperatures plunging 15-25°F below average. Dangerous wind chills as low as -20°F are expected in parts of North Dakota and the Upper Midwest. This cold air will spread across much of the eastern U.S. by Thanksgiving and into the weekend, resulting in a noticeable cooldown and the coldest air of the season for many locations.
Meanwhile, a low-pressure system tracking from the Ohio Valley to New England on Thanksgiving Day will bring widespread precipitation to the Northeast, with rain near the coast and a wintry mix or snow inland. This system will produce hazardous travel conditions for holiday travelers.
A dynamic and impactful weather period is shaping up for New England and upstate New York through the Thanksgiving holiday weekend.
Today, a frontal system will bring widespread rain across the region, transitioning to a mix or snow in northern areas, particularly across the higher terrain of Vermont, New Hampshire, and Maine. A Winter Weather Advisory is in effect for parts of northern Vermont and New York’s Adirondacks, where freezing rain or light snow accumulations could make travel hazardous this morning. Rainfall totals will generally range from 0.25 to 0.50 inches, with localized slick spots due to icing in sheltered valleys and higher elevations.
Behind this system, lake-effect snow will develop off Lake Ontario tonight into Wednesday. Western Adirondack and Tug Hill areas could see 2-5 inches of snow by Wednesday morning, with locally higher amounts where snow bands persist. Winds will also pick up behind the front, with gusts of 20-25 mph in exposed areas.
On Thanksgiving Day, a rapidly developing coastal low will spread widespread precipitation across the region. Coastal and southern areas, including Massachusetts, Rhode Island, and southern Connecticut, will see mostly rain, while inland areas—especially the Berkshires, southern Green Mountains, and White Mountains—could receive several inches of snow. Mixed precipitation is possible at the onset across interior valleys, but rain will dominate in lower elevations as temperatures climb above freezing. Snow totals of 2-6 inches are expected in higher terrain, with locally higher amounts possible in favored snow zones. Travel will likely be hazardous during the day, particularly for those heading north or into higher terrain.
Colder air will follow for Friday and into the weekend, with below-average temperatures and lake-effect snow persisting downwind of the Great Lakes. The Arctic air mass will bring highs only in the 30s for most areas and overnight lows in the teens and 20s, making for a brisk start to the holiday shopping season.
