Matt Noyes delivers some optimistic news in Noyes’ Notes to start our week, sharing – while our shortest daylight may not come until December 21 – our sunsets are already getting later! Of course, that doesn’t stop the winter weather from coming, and Matt says while the first couple of disturbances this week start warm, we’ll watch a snow line drop farther south with each one this week. Full details in the video, and our customary daily National and Northeast written weather summary are below!

National Meteorological Summary:
The United States is under the influence of active weather systems spanning both coasts and across the central regions.
- Pacific Northwest & Northern Rockies: An atmospheric river continues to bring moderate to heavy rain to coastal areas, with significant snowfall in the higher elevations of the Cascades and Rockies. Snowfall accumulations of 4 to 8 inches, with localized totals exceeding a foot, are expected through tonight. Conditions will shift northward into Washington State by Tuesday, where the heaviest rain and snow will concentrate on the Northern Cascades and northern Rockies.
- Eastern Half of the Country: A cold front will trigger scattered showers and thunderstorms across the Ohio Valley and Lower Mississippi Valley today. Some of these storms could produce heavy downpours, especially across the Ohio Valley. Rain is likely to overspread much of the Mid-Atlantic and Northeast by this evening, transitioning to a wintry mix over interior portions of the Northeast.
- Great Lakes: Light to moderate lake-effect snow is ongoing downwind of Lakes Erie and Ontario, supported by cooler air aloft and a conducive wind flow.
- Temperatures: Much of the central and eastern U.S. is experiencing above-average temperatures, with highs in the 50s and 60s expected in parts of the Midwest and Northeast. Cooler Arctic air will plunge into the Northern Plains by midweek, bringing high temperatures 15 to 20 degrees below average.
Northeast Weather Story:
Although there won’t be much precipitation falling in New England today, there’s a lot going on in the weather!
- Morning/Noon Hours: Early in the day, light snow transitions to a mix of freezing rain and drizzle across much of New York, Western to Central MA and Connecticut, leaving slick spots that have been requiring treatment. By midday and afternoon, temperatures climb into the mid-40s.
- Tonight: Rain redevelops and becomes becomes widespread as milder air surges in with strong southerly winds, though some pockets of freezing rain in deep, sheltered valleys of the North Country may occur at the onset late this evening. Wind gusts of 35-45 mph are expected in exposed areas, with some potential for stronger gusts in coastal Rhode Island and Cape Cod.
- Tuesday Transition: As a frontal boundary passes early Tuesday, precipitation will taper off and temperatures will remain fairly mild in the 40s and 50s, though cooler westerly winds will take over the farther north and west one is, introducing the risk of localized lake-effect snow showers into upstate New York and Vermont. Daytime highs Tuesday will remain above freezing, limiting snow impacts to higher elevations and downwind regions of the lakes.
