Area Forecast Discussion National Weather Service New York NY 1247 PM EST Sat Feb 8 2025

SYNOPSIS
High pressure over the area today moves offshore as low pressure approaches from the west and slides south of the area tonight. High pressure then builds back in on Sunday and Monday. A series of lows will impact the area Tuesday through Thursday. High pressure returns to end the week and start the weekend.

NEAR TERM /THROUGH TONIGHT/
Just some slight adjustments made with respect to hourly forecast temperatures, dewpoints and cloud coverage to better match observed trends. Pushed back likely POPs for snow an hour based on latest mesoscale model trends. Likely POPs for snow for SW parts of region start at 22Z. Otherwise, forecast on track.

High pressure continues to move over the area today with generally dry conditions and light winds. The center of the high pressure slides overhead and moves offshore into this evening ahead of an approaching low pressure system poised to impact the area tonight. Highs today will be in the low to middle 30s.

Low pressure over the Ohio Valley will shift east as it strengthens.
By evening, widespread light snow should overtake the area from west to east. As the frontogenetical forcing maximizes ahead of the low center, a more moderate to heavy snow should take over much of the area with the bulk of the accumulating snowfall expected to take place prior to midnight for much of the CWA During this period of moderate to heavy snow, 1-2" per hour rates will be possible for much of the area, though the locations of any mesoscale bands with heavier snowfall will determine if any locations end up with more snow than anticipated.

As the low slides south of the area, its proximity to the coast will determine how quickly the rate of precipitation decreases or any mix or change over of precipitation types occurs. Models still have uncertainty in the strength of a warm layer which would result in changing p-types. Generally the thinking is that after the strongest forcing pushes east after midnight, drying aloft will be able to limit both the intensity of the precipitation and also possibly limit ice nuclei in the column. This combined with the potential warm nose moving over the area may result in a mix with sleet and possibly freezing rain where the warm nose is strongest, more likely near the coast, though possible even for the Lower Hudson Valley and southern Connecticut. Any mix of p-types would limit snowfall totals. A mix in with plain rain is possible mainly for the NYC metro and Long Island as the precipitation intensity decreases if surface temperatures warm to just above freezing, though much of the bulk of the precipitation would have already occurred by this point, mainly in the form of snow or a snow/sleet mix.

As the low pulls away from the area, some wrap around cold air may allow for a transition back to very light snow as precipitation comes to an end around or shortly after daybreak.

The forecast snowfall totals remain fairly similar to the previous forecast, with perhaps a slight decrease in totals along the coast.
Generally 5-7 inches are expected for the Lower Hudson Valley and Southern Connecticut where Winter Storm Warnings remain in effect. A widespread 2-5 inches is expected across the southern half of the CWA from NE NJ, the NYC metro, and Long Island where Winter Weather Advisories remain in effect. A light glaze or a few hundredths of an inch of ice are possible across the CWA with the potential for some light freezing rain in the second half of the overnight.

SHORT TERM /SUNDAY THROUGH MONDAY NIGHT/
The low pressure pushes offshore with high pressure building in from the west through the day. Skies will be gradually clearing with a brisk NW wind of 10-15 mph with gusts upwards of 20-25 mph. Highs Sunday will be in the middle to upper 30s for much of the area allowing for some melting of the snowpack.

THe high continues to build over the area Sunday night, Monday and moves overhead by Monday night. During this time, generally partly cloudy or mostly clear skies and dry conditions are anticipated with a generally light NW flow. Lows Sunday night will be in the teens inland and low to middle 20s along the coast. Highs on Monday will be a bit colder than Sunday, generally in the low to middle 30s. Lows Monday night will be colder still with inland temperatures in the low teens and coastal areas in the upper teens to low 20s.Temperatures on Saturday get up into the lower/mid 30s, then fall into the upper 20s/lower 30s in the evening with the onset of snow, fluctuating little overnight.

LONG TERM /TUESDAY THROUGH FRIDAY/
Key Points:

* Snow possible Tuesday into early Wednesday.

* Uncertainty remains high for accumulating snow Wednesday through Thursday.

* Daytime high temperatures will be below normal for much of the week, with the exception of Thursday, with near normal overnight low temperatures.

A fast and nearly zonal flow aloft will continue Tuesday and Wednesday with a more amplified trough approaching the east coast Thursday and passing through Thursday night. High pressure builds north of the region early in the long term, locking cold air in place for Tuesday and Wednesday. The first of a series of low pressure systems approach Tuesday and passes south of the area Tuesday night. Most of the 00z forecast guidance has suppressed this system further the south than previous runs, keeping the area on the northern fringe of the precip shield. in fact, the 00z GFS has all the precipitation remaining offshore, with a dry forecast for us.
For now, will not make any drastic changes to the forecast, since, while the trend has been a further south progression with this system, most of the guidance does have some precipitation falling during this period. Any precipitation that does fall will be all snow, with enough cold air in place. With a slightly further shift southward, snowfall amounts remain rather uncertain.

There may be a brief break in the precipitation later Wednesday into Wednesday evening, however with the uncertainty with the timing of the lows will maintain at least chance probabilities.
With the next low pressure system quickly approaching late Wednesday, and being more amplified and a deeper surface low, chances remain high for additional snow accumulations at least across the inland areas. There will be increased moisture with this system as the low takes a southerly track and Gulf moisture entrains. With the inland system and a strong southerly flow with strong warm air advection, frozen precipitation will likely transition to rain along the coast, and mixed precipitation inland. And with the warm advection temperatures Thursday may be near to above normal.

High pressure and upper ridging build behind the low to end next week. Another low pressure system may approach late in the weekend.

AVIATION /18Z SATURDAY THROUGH THURSDAY/
High pressure slides east into the Western Atlantic this afternoon. Low pressure tracking through the Ohio Valley allows a leading warm front to approach this evening as a secondary low develops south of Long Island.

VFR thru this afternoon, before light snow begins to develop at the NYC metros/KISP by 00Z with vsbys quickly lowering to MVFR then IFR/LIFR. Precip mixes with and changes to sleet after 3Z.
The snow/sleet transitions to freezing rain/sleet, tapering as freezing drizzle possibly mixed with snow or ice pellets into early Sunday morning. For Hudson Valley/CT terminals, snow arrives by 3Z, with flight categories also lowering quickly to IFR/LIFR. The precipitation should be mostly snow, with a brief period of sleet possible, tapering off to either light snow or freezing drizzle Sunday AM. Conditions begin to dry out from west to east toward 12Z and thereafter, with conditions returning to VFR at all terminals by afternoon.

Winds are light and variable to start, becoming SE this afternoon as the high shifts offshore, then NE overnight. Flow backs NW as the system exits into late Sunday morning, with speeds increasing 10-15G25kt.

Airport Snow/Sleet Accumulations:

JFK/LGA/EWR/TEB/ISP: 3-5.
HPN/SWF/BDR/GON: 5-7.

...NY Metro (KEWR/KLGA/KJFK/KTEB) TAF Uncertainty...

Amendments likely this evening and overnight with changing flight categories.

OUTLOOK FOR 12Z SUNDAY THROUGH THURSDAY

Sunday: MVFR early, becoming VFR by noon. NW winds G20-25kt.

Monday: VFR.

Tuesday: Chance of snow in the afternoon, becoming likely at night.
IFR/LIFR conditions possible.

Wednesday: Chance of light snow/MVFR or lower cond, especially early.

Thursday: MVFR/IFR or lower with RA/SN.

MARINE
Sub-SCA conditions are expected on all the waters through tonight with high pressure in control today. Low pressure moves over the area tonight. As high pressure builds in Sunday, waves on the ocean increase to near 5-7 feet and wind gusts approach 25kt, so a SCA is in effect during the day on Sunday. Sub-SCA conditions then return for Sunday night through Monday night with high pressure overhead.

With a weak pressure gradient Tuesday into Wednesday, winds and seas will remain below advisory criteria across all the forecast waters.
Then with an increasing northeast flow with low pressure impacting the waters Wednesday night and Thursday SCA conditions will return to the area waters.

HYDROLOGY
There are no hydrologic concerns through the forecast period.
