High-Impact and Far-Reaching Winter Storm Continues; Cold Expands and Persists

A major winter storm will shift its impacts into the Northeast U.S. with heavy snow through tonight while over the Mid-Atlantic, sleet and freezing rain will diminish. Extremely cold air behind the storm will prolong dangerous travel and infrastructure impacts. Sub-zero low temperatures are expected nearly every morning from the Northern Plains through the Ohio Valley and into the Northeast. Read More >

.MARINE... Sustained winds of 20 to 30 knots (30 to 35 knots over the middle Chesapeake Bay) are expected, along with gusts of 35 to 40 knots (around 45 knots over the middle Chesapeake Bay). The trajectory of the winds channeling down the Chesapeake Bay as well as the 12- to 24-hour duration will also result in pretty impressive waves for this region - 2 to 4 feet over the narrower waterways, to 4 to 7 feet in the wider waters off southern Maryland. The combination of prolonged winds and waves with frigid temperatures will result in freezing spray over ice-free waters this morning. Freezing spray headlines are in effect where National Ice Center analysis shows ice-free waters. The heaviest freezing spray will be over the wider waters off southern Maryland where the highest winds/waves and most favorable fetch are expected. Winds will gradually subside tonight into Monday. Light winds will become southerly late Tuesday. A clipper-type low will scoot by to the south Tuesday night into Wednesday. Some light snow may accompany this system, followed by a shift in winds back to the northwest. Update as of: 349 AM EST Sun Feb 1 2026
