Monday Noyes’ Notes/1°Outside Today: Quick Improvement As Temperatures Rise

Many of us are starting out with lingering slick spots from overnight snow, but Matt Noyes says by mid-morning, temperatures are rebounding past the melting point for many in Southern New England, and by afternoon, nearly all of New England will.  Check out the next 24 hours and Noyes’ Notes with Matt here – and don’t forget to use the Community Gallery page of our website or the Send To Us tab of our app to keep us posted on how much fresh snow you’re waking up to!

National Weather Summary 

The weather pattern across the United States remains active to start the week, featuring a mix of heavy precipitation on the West Coast, winter weather in the Northern Rockies and Plains, and a developing system bringing mixed precipitation to the Northeast.

A powerful atmospheric river event continues to impact Northern California and the Pacific Northwest. Heavy rain, capable of producing localized flooding, will persist through Tuesday across the region, with rainfall totals of 5-10 inches in the Sierra Nevada. Meanwhile, heavy snow will blanket higher elevations of the Cascades and Northern Rockies, with accumulations exceeding 2 feet in some locations. A secondary system arriving Tuesday will reinforce snowfall across these mountain ranges and push the heaviest precipitation southward into Central and Southern California.

Further inland, a clipper system crossing the Northern Plains will spread light to moderate snow eastward across the Upper Midwest and into the Great Lakes and Northeast. While snowfall totals are not expected to be excessive, gusty winds accompanying this system may lead to localized blowing snow and reduced visibility in parts of the Upper Midwest.

In the East, an initial wave of precipitation will exit the region early Monday morning, but another disturbance tracking into the Great Lakes will bring rain and a wintry mix from Wisconsin to Pennsylvania Monday night. Snow will fall across portions of upstate New York and New England through Tuesday before tapering off. Cold high pressure over Central Canada will also allow Arctic air to spill southward, keeping temperatures well below normal across the Northern Plains and Upper Midwest, with highs struggling to reach zero degrees in parts of Montana and the Dakotas.

Meanwhile, much of the southern U.S. will continue to experience mild temperatures, with highs running 10-20 degrees above normal from Texas to the Southeast. Some locations may approach record highs in the mid-70s to near 80°F midweek.

Northeast Weather Story

A busy stretch of winter weather continues across the Northeast, with multiple rounds of snow, mixed precipitation, and rain expected this week.

Light snow associated with a fast-moving clipper system will taper off this morning after dropping 1-4 inches across parts of New York and New England, with higher amounts in the higher terrain of Vermont, New Hampshire, and western Massachusetts. Some areas may also see patchy freezing drizzle as the system exits.

A brief break in precipitation follows during the day Monday, allowing temperatures to warm into the 30s and 40s for much of the region. However, another system will approach from the west Monday evening, bringing a mix of rain and snow showers. Some freezing rain is possible across northern New York and northern New England before temperatures warm enough to support plain rain overnight. As the cold front passes, rain will change back to snow, with upslope snowfall expected in the Green and White Mountains through Tuesday.

Tuesday will be marked by blustery northwest winds and colder air filtering into the region, with lake-effect and upslope snow showers continuing in northern New York and Vermont. Accumulations will generally be light but could be locally heavier in favored terrain areas.

Looking ahead, another storm system is poised to impact the Northeast Wednesday night into Thursday. This system could bring a widespread wintry mix, with snow at the onset transitioning to sleet and freezing rain, particularly in interior areas. Coastal regions will likely see a change to rain as warmer air moves in. This event has the potential to create hazardous travel conditions, and further refinements to the forecast will be needed in the coming days.

After this system exits, cold high pressure will briefly return Friday before yet another potential storm develops next weekend, continuing the active pattern in the Northeast.
