Synopsis for the long island and connecticut coastal waters - High pressure will be in control through Wednesday. Offshore high pressure going into midweek gives way to an approaching cold front Thursday. The cold front moves across Thursday night and stalls south of the region as waves of low pressure track along the stationary front. Another cold front moves across the region Saturday.

Area Forecast Discussion National Weather Service New York NY 737 AM EDT Tue May 21 2024

SYNOPSIS
High pressure will be in control through Wednesday. Offshore high pressure going into midweek gives way to an approaching cold front Thursday. The cold front moves across Thursday night and stalls south of the region as waves of low pressure track along the stationary front. Another cold front moves across the region Saturday. Another frontal system affects the area early next week.

NEAR TERM /THROUGH TONIGHT/
The forecast is on track with only minor changes needed.

High pressure slowly pushes off the East Coast today, but remains over the area enough to keep the area dry. An upper level ridge pushes east, but flattens as an upper level shortwave over the Great Lakes region moves east, passing well north of the area.

Any stratus and fog will burn off early this morning, allowing for a mostly sunny day. With full sun, today will be a warm day, especially for the interior, where a southwesterly flow advects a warm and increasingly more humid air mass today. Continued the trend of blending the 50th percentile with the deterministic NBM, which gives high temperatures in the middle 80s for northeast New Jersey and the Lower Hudson Valley. Elsewhere, temperatures in the 70s to near 80 can be expected, with the immediate shore seeing upper 60s for highs thanks to onshore flow and relatively cooler ocean temperatures. Dew points will rise into the upper 50s to middle 60s. Lows tonight will only drop to the 60s across New York City, northeast New Jersey, and the Lower Hudson Valley. Elsewhere, lows in the 50s can be expected.

There may be another round of stratus and fog, moving in from the east. However, confidence was not high enough to include in the forecast, but some guidance is pointing to this scenario once again.

SHORT TERM /WEDNESDAY THROUGH THURSDAY/
The high slowly moves east on Wednesday allowing a pre-frontal trough to approach during the day. However, much, if not all the area, will remain dry. There is just a slight chance for showers and thunderstorms for the extreme western portion of Orange County on Wednesday.

Continued well above normal temperatures for Wednesday and Thursday, with highs in the middle to upper 80s away from the coast (approaching 90 for northeast New Jersey). The coast will see temperatures range from the upper 60s to lower 80s for highs on Wednesday, and a couple of degrees warmer on Thursday.

High pressure will eventually give way to an approaching cold front Wednesday night into Thursday. The parent low attached to this front will be weakening as it moves farther north of the Great Lakes leading to a weakening of the cold front.

There will be a chance for showers and thunderstorms out ahead and along the cold front for Thursday into Thursday night. The cold front is forecast to move across Thursday night. Chances for showers and thunderstorms decrease late Thursday night after the cold frontal passage.

There is potential for some thunderstorms to be strong to severe with the cold front with forecast surface CAPE values of 1000-2000 J/kg and forecast 0-6 km AGL bulk shear of 30 to 35 kt. Right now, coverage is expected to be isolated to scattered of, mainly for points north and west of New York City. No hydrologic concerns at this time as showers and thunderstorms will be fast moving, really limiting total rainfall accumulations.

The Storm Prediction Center has placed the entire area in a marginal risk for severe thunderstorms,

LONG TERM /THURSDAY NIGHT THROUGH MONDAY/
There is currently a lot of uncertainty through the extended period with timing of a cold frontal passage Thursday night, and where this front will eventually stall. Waves of low pressure are expected to track along the stationary front which may bring a chance pf precipitation, showers, and potentially thunderstorms, to the area.
Near upper level zonal flow will bring a more amplified trough north of the Great Lakes and into southeastern Canada Saturday into Saturday night, with another cold front approaching the region before weakening. Then for early next week an even more amplified trough will pass through the Great Lakes and northeast bringing a surface low across the region. While there are chances for precipitation during most of the extended period there will also be periods of dry weather.
With the uncertainties have followed the NBM probabilities.
Otherwise, a warm airmass will remain across the region with temperatures above normal Thursday night into the beginning of next week.

AVIATION /12Z TUESDAY THROUGH SATURDAY/
Weak surface high pressure remains over the area through Wednesday.

Lingering IFR to LIFR stratus and fog will be dissipating this morning, with timing uncertainties, and may remain at KGON a little longer than forecast, becoming MVFR which may linger into the afternoon. Otherwise VFR with southerly winds increasing this morning to around 10kt.

There is a chance of MVFR to IFR stratus developing late tonight at KISP, KBDR, and KGON.

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

Timing of improving conditions at KJFK may as early as 13Z.
Otherwise VFR with no unscheduled amendments expected. Winds at KJFK may be as high as 15kt with sea breeze enhancement.

OUTLOOK FOR 12Z WEDNESDAY THROUGH SATURDAY...

Wednesday: Mainly VFR. Any MVFR to IFR conditions east of the NYC metro terminals will quickly become VFR soon after 12Z.
R during Wednesday morning. IFR is possible again late Wednesday night, mainly east of the NYC terminals.

Thursday: VFR in the morning, then becoming MVFR with showers and thunderstorms likely during the afternoon.

Friday: VFR.

Saturday: Generally VFR. A chance of showers with MVFR.

MARINE
Dense fog over the bays and the eastern sound and eastern ocean zones continue this morning, with improvement still expected after 11 am. There may be another round of fog tonight, but not enough confidence to mention fog on the waters at this time.

Otherwise, sub-advisory conditions are expected across all waters through Thursday. However, this afternoon and Wednesday afternoons are likely to see a coastal jet produce gusts up to 20-25 kt, especially on Wednesday, and seas of 3 to 4 ft in the NY Bight along with seas possibly touching 5 ft.

Winds and seas will be below SCA levels across the forecast waters Thursday night through Saturday night.

HYDROLOGY
No hydrologic impacts expected through the forecast period.

OKX WATCHES/WARNINGS/ADVISORIES
CT...None.
NY...None.
NJ...None.
MARINE...Dense Fog Advisory until 11 AM EDT this morning for ANZ332-340- 350.
