Area Forecast Discussion
National Weather Service New York NY
508 PM EST Mon 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 precip Thursday into Thursday night.
&&
.DISCUSSION...
.KEY MESSAGE 1...
The intense coastal low that has brought several feet of
snowfall to portions of the area today continues to pull
northeast into tonight. Given the tight pressure gradient
remaining in place, gusty winds this evening will gradually
diminish overnight. Gusts of 35-50 mph remain possible, especially
along the coast through this evening. Winds weaken substantially
by midnight so that gusts will be closer to 20-35 mph. Wind
continues to decrease into Tuesday morning. These gusty winds
may result in locally reduced visibilities overnight and
through the Tuesday morning commute. An SPS has been issued to
highlight this concern.
Additionally, black ice will remain possible across the area
tonight, especially on any untreated surfaces, as temperatures
drop below freezing again tonight. The SPS highlights this
potential as well.
.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.
&&
.AVIATION /21Z MONDAY THROUGH SATURDAY/...
Deepening low pressure continues to lift to the northeast
through the TAF period.
Conditions are starting to improve as snow bands across the
area continue to dissipate. There still continue to be some
snow bands that could produce a brief period of 1/4sm through
the next hour or two. Otherwise, expect to the snow to end from
west to east this afternoon and evening. Improvements to MVFR
likely by afternoon.
In addition, with the gusty winds across the region, expect
areas of blowing snow through the day today.
NE winds 25-35 kt with gusts 35-40 kt expected early this
afternoon, then winds will gradually diminish through the
evening and overnight.
...NY Metro (KEWR/KLGA/KJFK/KTEB) TAF Uncertainty...
Amendment is possible for changing flight categories this
afternoon.
.OUTLOOK FOR 18Z MONDAY THROUGH FRIDAY...
Tuesday: VFR. NW winds gust 20-25kt.
Tuesday Night-Wednesday: MVFR possible with chance of light
snow Tuesday night, then rain/snow mix Wednesday.
Thursday: MVFR or lower. Rain/snow mix possible near coast with
snow possible inland.
Friday: Mainly VFR.
Saturday: VFR.
