| Area Forecast Discussion National Weather Service New York NY 757pm EST Monday Feb 23 2026 .WHAT HAS CHANGED... The Blizzard Warnings have been cancelled and an SPS has been issued. .KEY MESSAGES... 1) Impactful winter storm continues to exit the area tonight. Gusty winds and blowing snow remain possible. 2) A passing warm front will bring some light snow and rain on Wednesday. A stronger low passing close by will bring additional wintry precipitation Thursday into Thursday night. .KEY MESSAGE 1... The intense coastal low that has brought 18-30" of snowfall to much of the area today will continue to track northeast into the Canadian Maritimes tonight. Gusts of 30-40 mph will gradually decrease through the overnight, becoming more occasional and closer to 20-30 mph late tonight thru Tuesday aft. These gusty winds will result in areas of blowing snow and locally reduced visibilities overnight into the Tuesday morning commute. Additionally, areas of black ice will be likely across the area tonight, especially on any untreated surfaces, as temperatures drop below freezing again tonight. An SPS highligheights these potentials. .KEY MESSAGE 2... As a clipper low passes to the north on Wednesday, an associated warm front should bring some light snow and rain on Wed. Accumulations should be on the light side, ranging from less than an inch across Long Island, to around an inch in NYC and along the CT coastline, to 1-2 inches north/west of there. A stronger low moving from the OH valley to the lower Great Lakes on Thu could bring more wintry precip. NBM thermal profiles were mainly supportive of snow and/or rain. Any snow amts should be light, no more than an inch or two of snow most places and a light glaze of ice inland NW of NYC. Either way advisories could be needed for parts of the interior north/west of I-287 in NJ/NY and along the I-84 corridor in CT. High temperatures Tuesday range from the upper 20s to lower 30s, then trend closer to normal the rest of the week. This will allow for gradual snow melt each day, and with mostly sub-freezing temperatures at night into early morning, subsequent re-freeze of snow melt. Marine A major winter storm continues to move away from the waters tonight. Gale Warnings across all waters until 1 AM. Strong winds with gusts of 30-45 kt will continue to gradually dissipate this evening and overnight. Seas of 10-15 feet will fairly quickly diminish overnight so that by Tuesday morning, ocean seas should be 5-7 feet. SCA (Small Craft Advisory) conditions linger into Tuesday morning on the eastern Sound and Peconic/Gardiners bays, with NW flow still gusting up to 25 kt, and on the ocean for gusts up to 30 kt for seas 6-8 ft. Some 5-6 ft seas should linger on the ocean into early Tuesday evening. An extended period of SCA (Small Craft Advisory) cond then likely on the ocean from Wednesday into Fri as a series of frontal systems pass through, mainly for hazardous seas. SW flow 20-25 kt expected on the ocean with warm frontal approaches daytime Wednesday and again Thu night. NOAA New York NY Office: Watches - Warnings - Advisories CT...None. NY...None. NJ...None. Marine Gale Warning until 1am EST Tuesday for ANZ331-332-335-338-340- 345-350-353-355. |
