980 FXUS01 KWBC 272001 PMDSPD Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 300 PM EST Sat Dec 27 2025 Valid 00Z Sun Dec 28 2025 - 00Z Tue Dec 30 2025 ...Arctic air will descend into the Plains tomorrow, followed by a potent winter storm from the upper Midwest to the Great Lakes Sunday into to Monday... ...Record warmth continues across the Central and Southern U.S. this weekend... With winter weather ended over New England this afternoon, much of our attention will turn westward to the Plains and Upper Midwest as a compact upper-trough analyzed over the Northern Rockies displaces a frigid Arctic airmass southward. In turn, the next big storm system is forecast to rapidly intensify along the Arctic front over the Midwest tomorrow, before tracking through the Great Lakes on Monday. A slew of winter weather hazards are expected to accompany this storm beginning late tomorrow, including blizzard conditions and over a foot of snowfall over portions of the Upper Midwest and Great Lakes. At the same time tomorrow, increasing southerly flow overrunning a shallow sub-freezing airmass will yield increasing coverage of freezing rain over much of the Interior Northeast, which then spreads into the northern Appalachians Monday. Much of these areas can expect at least a tenth of an inch of ice with this event, while portions of the Adirondacks, Greens, and Whites could eclipse a quarter to half an inch of ice by Monday per the latest forecast. Western Pennsylvania and New York are also "under-the-gun" from this event, as the passage of the Arctic front stir ups locally heavy lake-effect snowfall downwind of Lakes Erie and Ontario on Monday. Even areas in the Northern Plains which do not see impactful precipitation from this system should keep tabs on the forecast, as bitterly cold wind chills as low as -30 degrees can be expected in parts of North Dakota and Minnesota following the passage of the front. For the rest of the Central U.S, this front should usher in a dramatic change to the record breaking warm weather which has gripped the region over the last week. Until the front swings through later tomorrow, however, widespread record breaking warmth will continue across the Central/Southern Plains and Southeast, where some cities could break or near break record highs dating back to the 1880s.
