Matt Noyes looks ahead in Noyes’ Notes, beyond our mild and wet start today – but for now…and for most of the purposes of this 24-hour forecast video…exceptional warmth, a wet start and a gusty morning wind takes the headline. Matt has it all in our video and, as usual, the National and Northeast Summaries are below!
The United States remains under an active weather regime. A strengthening low-pressure system tracking through the Great Lakes will bring widespread precipitation to the eastern half of the country. Rain and embedded heavier showers will dominate from the Mid-Atlantic to the Northeast early Monday, transitioning to scattered showers in the Ohio Valley as the associated cold front moves east. In the colder air behind the front, lake-effect snow will develop across the Great Lakes, producing localized snowfall accumulations through midweek.
Out west, a weakening atmospheric river continues to bring showers and mountain snow to the Pacific Northwest and northern Rockies. Snow levels are expected to lower through the day, bringing accumulations to the Cascades, Idaho Panhandle, and parts of Montana. The Sierra Nevada will also see lingering snow showers.
Meanwhile, the central and southern U.S. will experience much warmer-than-average temperatures, with highs in the 60s and 70s across the Plains and Southeast. A critical fire weather threat exists for the Southern High Plains due to gusty winds and dry conditions.
Looking ahead, colder air is poised to return to much of the northern and eastern U.S. later this week as another system develops over the Plains and tracks toward the East Coast.
An approaching cold front will bring a mild but wet start to the day across the Northeast. Widespread rain will taper off from west to east by midday, accompanied by gusty winds. Morning temperatures will rise into the 50s, with potential record-breaking highs in parts of New England before cooler air filters in behind the front. Expect improving conditions by afternoon, with clearing skies and a shift to a west-southwest wind.
Despite the improvement, lake-effect snow showers will develop across western and northern New York late in the day as cold air moves over the relatively warm waters of the Great Lakes. Snowfall accumulations will be modest through Monday evening but are expected to increase in coverage and intensity overnight into Tuesday.
Coastal areas from Long Island to southern New England will experience breezy conditions, with gusts up to 40 mph possible, while winds across interior sections will peak at 25 to 30 mph. Temperatures will remain above average into Monday night, with lows in the mid-30s to low 40s across the region. However, a notable cool-down is on the way later this week as a more wintry weather pattern sets in.
