783 FXUS01 KWBC 301842 PMDSPD Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 141 PM EST Sun Nov 30 2025 Valid 00Z Mon Dec 01 2025 - 00Z Wed Dec 03 2025 ...As one winter storm ends for the Midwest/Great Lakes, another potential storm will follow quickly for New England and the Mid-Atlantic... ...Chilly temperatures continue across much of the eastern and central U.S. in a winter-like pattern... A deep longwave trough over the West will funnel in moisture over parts of the Pacific Northwest, Great Basin and the Rockies, with possible localized heavy snow over higher terrain, while lower elevations may experience some light snow showers through the remainder of today. Heading into Monday, the trough continues to advance eastward, the system will become more widespread with chances of precipiation over the Central Plains into the Mississippi Valley. Precipitation will range between showers and thunderstorms over Texas and parts of the Southeast, as the system merges with moisture from the Gulf. Weather Prediction Center has highlighted a Marginal Risk (level 1/4) for Excessive Rainfall for parts of the Gulf Coast and Deep South. Meanwhile further north, expect a wintry mix and snow over the lower parts of the Midwest/Great Lakes, Central Plains, Mississippi Valley, and Ohio Valley where the moisture will intertwine with colder air mass by Monday evening. Over the Upper Midwest/Great Lakes, lake-effect may increase chances of heavier snowfall. Therefore, several regions continue to issue Winter Weather Advisories, especially over the Upper Midwest and Upper Great Lakes. The frontal system that brought much of the heavy snow over the northern portions of CONUS, will gradually move into southeastern Canada today, tapering off the heavy snow with some possible lingering snow over areas over the Great Lakes that experience lake-effect. As the surface low deepens and the frontal system moves northeastward, expect possible widespread showers/thunderstorms along parts of the Mid-Atlantic and East Coast Monday through Tuesday. The deepening low, will gradually move towards New England, aiding in wintry precipiation Monday into Tuesday, especially for higher elevations. Chances for snow will be higher over parts of the Appalachians, the interior parts of New England, and northern Mid-Atlantic. South of the heavy snow, over the Central and Southern Appalachians, there are chances for light to moderate freezing rain and icing over the higher terrain. As the upper-wave moves eastward and the surface cold front moves through the region, temperatures over the Northern Plains, Upper Midwest and Interior Northeast will see below normal temperatures, with a 12-25 degree difference. Some areas over north-central U.S. can see high temperatures within the teens 20s. The latest cold front has brought the coldest air of the season so far to the central/southern Plains east to the Mid-South, with highs Monday mainly in the 20s to 40s. To the east, highs will be in the 30s and 40s for New England and the Mid-Atlantic with 40s and 50s into the Southeast. The only areas to see some reprieve from the cold will be along the Gulf Coast and southeast Atlantic Coast as temperatures climb into the 60s and 70s on the south side of the lingering frontal boundary. Conditions will be around or a bit above average in the West, with 40s for the interior, 50s and 60s along the West Coast, and 60s and 70s into the Desert Southwest. Heading into Tuesday, the central Plains begin to see near normal temperatures. Oudit/Putnam Graphics available at https://www.wpc.ncep.noaa.gov/basicwx/basicwx_ndfd.php $$
