Significant Winter Storm to Bring Heavy Snow and Ice Impacts; Dangerously Cold Temperatures Expands Across the East

A significant, long-duration winter storm will bring widespread heavy snow, sleet, and freezing rain from the Southern Rockies to New England through Monday. Widespread travel disruptions, prolonged power outages, and vast tree damage is likely. Frigid temperatures, gusty winds, and dangerous wind chills will expand from the north-central US to the Southern Plains, MS Valley, and Midwest. Read More >

Latest Marine Discussion:
.MARINE... Sub-SCA criteria winds are expected this morning. Northwest winds gust 20 to 25 knots over the waters this afternoon and persist through the overnight. Cold temperatures may lead to possible freezing spray, especially as winds approach gale- force tonight. Gusty winds and freezing spray likely linger through the weekend as a major winter storm tracks across the region. Northeast winds on Sunday shift to northwest on Monday with SCA criteria winds possible both days. Winds will be greatest on Monday, gusting near Gale conditions across the open waters of the Chesapeake Bay. Freezing spray remains likely Sunday and Monday. As the winter storm moves offshore, northwesterly winds increase markedly through the day on Monday. Gale conditions look possible across portions of the waters, especially the Chesapeake Bay, through late Monday. Eventually winds decrease into the night and Tuesday, but Small Craft Advisories will likely be needed through at least Tuesday morning. Sub-advisory winds return to the picture for the rest of Tuesday while winds shift to southwesterly. Update as of: 333 AM EST Fri Jan 23 2026
