Matt Noyes lays out the next 24 hours – plus Noyes’ Notes with the big themes of our New England forecast – here in our 1°Outside Today video. Watch and see just how cold it’ll feel in your town today!
A highly amplified spring pattern continues across the continental United States as a series of disturbances carve a strong trough across the eastern third of the country while ridging dominates the West.
Southeast U.S.: The lingering frontal boundary and associated waves of low pressure continue to produce heavy rainfall and scattered severe thunderstorms. Flash flooding concerns are greatest across central/southern Alabama, with isolated severe storms possible into the Carolinas and coastal plain of Georgia through today. Fortunately, the threat begins to diminish as the front exits offshore later tonight.
Wintry Weather, Great Lakes to Northeast: In the colder airmass north of the front, a series of disturbances are supporting accumulating snow from the Upper Great Lakes into interior New England. This includes lake-effect snow showers and localized heavier bursts of snow associated with frontal passages.
Pacific Northwest & Rockies: Moisture-laden Pacific systems continue to sweep into the Pacific Northwest and Northern Rockies. Heavy mountain snow is expected in the higher elevations of the Olympics, Cascades, and Northern Rockies, while valley locations see periods of rain.
Warming West: Much of the Western U.S. remains dry and unseasonably warm. Highs in the Desert Southwest are pushing into the 90s, while the Intermountain West and High Plains warm steadily through the week.
Midweek Outlook: A new potent shortwave drops out of south-central Canada midweek and spawns a developing surface low that tracks across the Midwest to the Mid-Atlantic by Friday. Some terrain-enhanced snowfall is possible in interior New England as this system approaches, with rain developing along the coast by Friday night. This could become a strong coastal low into the weekend with enhanced precipitation and marine hazards along the East Coast.
A complex and dynamic pattern continues across the Northeast, featuring a wintry mix today, a strong cold front Monday night into Tuesday, and another potentially impactful system late in the week.
Low pressure moving off the Mid-Atlantic coast today spreads a band of precipitation into southern New England and parts of eastern New York. Cold air remains marginally supportive of snow for interior valleys and especially elevations above 1,000 feet, where 1–2.5 inches of wet snow is likely. A mix of rain and sleet is expected closer to the coast and in lower elevations. Even a light coating of snow is possible down to the I-95 corridor (Boston-Providence-Hartford) during the morning hours before temperatures edge just above freezing.
Travel impacts for the morning commute are expected in the Berkshires, Worcester Hills, southern Greens, and Catskills due to reduced visibility and slippery roads. While main roads will generally be just wet, untreated secondary roads and elevated surfaces could be slick in the hills.
As the coastal low pulls away, precipitation becomes more scattered Monday afternoon. However, don’t let your guard down: the second act arrives Monday night.
A potent shortwave and rapidly strengthening low over Ontario will drive a powerful cold front across the region after midnight Monday. This front will bring:
A burst of snow or snow squalls: These may produce short-lived but intense snowfall with reduced visibility and a quick coating to 1” of accumulation, especially across the Adirondacks, Mohawk Valley, Capital District, Berkshires, and southern Vermont.
Strong NW Winds: Gusts of 30–45 mph are expected late Monday night through Tuesday, especially down the Mohawk Valley, into western Massachusetts and coastal New England. This may result in spotty power outages, minor tree damage, and difficult driving for high-profile vehicles.
Falling Temperatures: Temperatures plunge behind the front, with Tuesday highs stuck in the 30s to low 40s. Wind chills will be in the 20s across much of the interior. Freeze conditions are expected Tuesday night, even along the coast and in urban centers like Boston and Providence.
Tuesday and Wednesday are dry but unseasonably cold. Skies clear Tuesday night under a strong high, and temperatures bottom out in the 20s region-wide with teens in northern New England and higher terrain. These are hard freeze conditions for areas where the growing season has already begun.
By Thursday, winds shift southerly, warming the region modestly. However, moisture increases ahead of a developing coastal low. Rain returns Thursday night into Friday, with potential for:
Interior Snow/Mix to begin, especially in the higher elevations of New York and central/northern New England.
Steady Rain, Breezy Winds Friday into Saturday for much of the region as low pressure rides up the coast. The exact track remains uncertain, but trends are increasingly pointing toward an impactful maritime system with enhanced rainfall and gusty winds Friday–Saturday.
Marine Interests & Emergency Managers should monitor the evolving coastal storm threat for potential gale-force winds and heavy rain, especially along eastern Massachusetts and Downeast Maine.
