Major Winter Storm in the North-Central U.S.; Severe Weather from the Mid-South to Ohio Valley

A major winter storm will bring a swath of heavy snowfall, strong winds, blizzard conditions and freezing rain to the Northern Plains into the Great Lakes region. A line of storms will be capable of producing widespread damaging winds, tornadoes, and some large hail from the Mid-south to the Ohio Valley and the Southeast. Critical fire weather concerns shift to the southern Rockies and Plains. Read More >

Latest Marine Discussion:
.MARINE... Southeasterly winds are expected to increase today given the combination of high pressure near New England and a stalled frontal zone over the Carolinas. Small Craft Advisories go into effect across all marine zones at 9 AM this morning, while continuing through 1 PM Monday. However, these will be extended into subsequent days ahead of a seasonably strong cold front. A Gale Watch is in effect from Monday afternoon through late Monday night with gusts up to 35 knots expected. The limiting factor is the 60s to low 70s air temperatures on top of waters in the 40s. Severe thunderstorms are likely to impact the waterways late Monday afternoon and into the evening. Special Marine Warnings are expected for many of the thunderstorms, some of which could produce waterspouts. The stronger storms will be capable of marine wind gusts to around 55 to 65 knots. Any convective risk ends late Monday behind a strong cold front. Advisory to near gale caliber winds continue as winds shift to northwesterly on Monday night. Small Craft Advisories remain likely Tuesday in gusty westerly flow. A high end scenario would be close to gale conditions. Winds will diminish Tuesday night as high pressure builds overhead. Light south winds are expected Wednesday and Thursday. Update as of: 954 AM EDT Sun Mar 15 2026
