Area Forecast Discussion National Weather Service New York NY 1036 PM EST Fri Feb 26 2021

SYNOPSIS. High pressure continues to retreat to the east tonight, while a frontal system approaches from the southwest. The system will pass through the area on Saturday. Weak low pressure passes nearby to the south Sunday into Sunday night. A cold front then approaches on Monday and passes through during the afternoon to evening hours. High pressure then returns for Tuesday. Low pressure then passes to our south Wednesday into Wednesday night, otherwise high pressure remains in control through Thursday.

NEAR TERM /THROUGH SATURDAY/. Leading edge of rain has worked across southern NJ and SE PA, working NE. Still on track to move into the NYC/NJ metro toward 2 AM, then overspreading the remainder of the area by 5 AM. Minor adjustments made with this update. Temperatures will pretty stay steady, or slowly rise from this point.

A wintry mix of snow and sleet is possible at the onset across the interior. Bufkit does hint at a real brief window for fzra before the total changeover to rain on across this area. A brief hour of pcpn mixed with fzra was therefore included for the nwrn portion of the county where confidence is highest. Not enough coverage for an advy, so any fzra will need to be covered with an sps. No advy for snowfall as well, with amounts across the cwa expected to be less than an inch attm. Low rates while the airmass supports snow is expected to be a limiting factor. All areas are expected to be all rain by 15z, with the rain tapering off in the aft from w to e as a weak low passes and mid lvl dry air currently over TX surges in. The models were in agreement wrt timing, so the 15z sref was used for pops. A combination of the NBM and CONSALL was used for temps.

SHORT TERM /SATURDAY NIGHT/. Aftn convection centered around AR on Sat is progged to spawn the next sys that will impact the cwa. After some decreasing cloudiness in the eve, clouds associated with the convective complex may begin to reach the cwa. High clouds entrained in the subtropical Pacific jet should be the first to get here after midnight. Otherwise, dry wx is expected attm with the NBM used for temps.

LONG TERM /SUNDAY THROUGH FRIDAY/. A weak low center approaches us on Sunday, passing over or just south of the forecast area Sunday night. This will bring rain, mainly in the afternoon, but rain chances will linger into the night with a surface trough nearby. High temperatures near normal.

Drying on Monday with above normal temperatures as a westerly flow sets up ahead of an approaching cold front. The cold front passes through dry either late in the afternoon or in the evening. Breezy conditions develop, and NW winds will likely gust through the night as the strongest cold advection sets in. An upper trough axis and shortwave will be passing through as well Monday night. Not much moisture depicted by the models during this time, but will leave in a chance of flurries.

Deep-layered ridging then occurs for Tuesday with dry conditions and below normal temperatures. ECMWF/GFSv16/GDPS show low pressure passing well to our south during the Wednesday to Wednesday night period. Overall, a drier trend from 24 hours ago, but will leave in low chances of rain for the period, focused toward the southern zones. High pressure otherwise dominates through Thursday with dry weather and above normal high temperatures. Low confidence forecast for Friday, but for now will go with slight chance PoPs with the potential of a cold front or wave of low pressure brining PCPN to the area.

AVIATION /04Z SATURDAY THROUGH WEDNESDAY/. High pressure will continue to retreat to the east tonight, while a frontal system approaches from the SW. The system will move across the area on Saturday.

VFR through the first half of the night, lowering to MVFR overnight and then IFR by mid to late morning Saturday. Mainly rain will coincide with these lowering flight categories, however, there could be a 2 to 3 hour window at KSWF of mixed precipitation. VFR conditions return toward 00Z Sunday.

SE winds less than 10 kt will back to the E/SE, increasing to around 10 kt late at the coast. A frontal wave will move across the area in the afternoon with winds briefly going and light and variable before becoming W/SW at 5 to 10 kt from 21Z to 22Z.

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

Timing of IFR may be off 1-2 hours. Possible southerly LLWS after 12Z Sat, ending from west to east by 21Z.

OUTLOOK FOR 00Z SUNDAY THROUGH WEDNESDAY. Saturday Night. Becoming VFR early. Sunday. Mainly VFR in the morning. MVFR or lower with a chance of rain in the afternoon and at night. Monday. VFR. W wind G20-25kt in aft. NW wind G30-35kt possible eve and night. Tuesday. VFR. NW wind G20-25kt possible. Wednesday. Low chance of MVFR in rain.

MARINE. Winds and seas will remain blw sca lvls tngt. Winds and waves pick up on Sat. A sca remains in effect on the ocean.

SE swells will likely keep ocean seas at SCA levels through Sunday night and potentially for all of Monday as well. Westerly winds increase through the day Monday ahead of a cold front. The strongest cold air advection and gusts occur during Monday night behind the front's passage. Gale force gusts are looking more likely during the night for some, if not all of the waters during the night and may last into a part of Tuesday morning. Thereafter, high pressure then settles in with more tranquil conditions for Tuesday Night. Low pressure is expected to pass well to the south on Wednesday into Wednesday night. While winds might not be much of a concern, there is still a chance that a swell pushes wave heights into advisory criteria on the ocean.

HYDROLOGY. No hydrologic impacts are anticipated through Wednesday.
