National Short Range Forecast Discussion
Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 300 PM EST Sun Jan 25 2026 Valid 00Z Mon Jan 26 2026 - 00Z Wed Jan 28 2026 ...An expansive winter storm continues to bring heavy snow across the lower Great Lakes, interior Northeast and severe icing from the interior Southeast to the Mid-Atlantic through this evening... ...The same storm system is expected to bring a risk of severe thunderstorms across the eastern Gulf Coast region into early this evening... ...Record-breaking cold across the Southern Plains to the lower Mississippi Valley through Tuesday morning; record cold possible across interior Mid-Atlantic Tuesday morning... An expansive winter storm continues to be in progress from the Midwest through much of the Northeast while heavy icing is ongoing across the interior section of the East Coast as far south as the northern suburbs of Atlanta, Georgia this Sunday afternoon. The low pressure system responsible for this winter storm will move through the Appalachians late this afternoon as a new low pressure center develops just off the Mid-Atlantic coast and then slides off the New England coast Monday morning. Heavy snow is forecast to overspread from west to east across Pennsylvania and New York state followed by central and southern New England through tonight before the snow gradually tapers off finally for southeastern New England early Monday morning. Widespread heavy snowfall of a foot to locally 2 feet possible across the interior Northeast and New England including Boston and New York/New Jersey metropolitan areas. Meanwhile, a wide swath of sleet will continue to impact areas just to the south across the interior Mid-Atlantic into coastal New England before ending as a wintry mix this evening. Still farther south, severe icing is expected to impact interior East Coast as far south as the northern suburbs of Atlanta, Georgia into early this evening with the passage of a cold front. In addition, severe thunderstorms are possible through early this evening across the eastern Gulf Coast region along with heavy downpours. The entire storm system will move off the East Coast into the Atlantic on Monday. Arctic air will then rush in behind the storm system and bring bitterly cold temperatures for much of the eastern two-thirds of the country for the next couple of days. In fact, below freezing temperatures will penetrate south of Brownsville, Texas Monday morning, along with below zero readings across the Texas Panhandle and into Oklahoma. These bitterly cold temperatures will be at record-breaking levels across the entire southern Plains. In addition, brisk northerly winds will produce dangerously cold wind chills! More record cold temperatures are expected across the southern Plains into the lower Mississippi Valley Tuesday morning as low temperatures dips into the single digits across the interior Mid-Atlantic, which will challenge some records. Across the northern Plains to the upper Midwest, frigid temperatures down into the -10s to -20s are forecast for Monday morning. An Alberta clipper will then arrive Monday night before moving through the Great Lakes on Tuesday, bringing snow showers and possibly brief periods of snow squall across the region. Temperatures will moderate some late on Monday before a replenishment of arctic arrives on Tuesday for the northern U.S. Across the northern High Plains to the northern Rockies, a reinforcing arctic front is bringing a period of snow into the Colorado Rockies and the central High Plains through tonight. Some snow is also in progress across northern Texas into early this evening. Meanwhile, the entire western U.S. will remain quiet weatherwise, where generally milder than normal temperatures will be in contrast to the cold and wintry weather across the remainder of the country. Across the Great Lakes, lake-effect snows can be expected to linger through the next couple of days in addition to the snowfall associated with the ongoing winter storm across the lower Great Lakes. The Sunshine State will see below freezing temperatures across the Panhandle/northern Peninsula Tuesday morning. Kong Graphics available at https://www.wpc.ncep.noaa.gov/basicwx/basicwx_ndfd.php
