SYNOPSIS
A low pressure system moves north of the area Wednesday, with its associated warm front moving north late overnight into early Wednesday morning. Another low pressure system approaches along a frontal boundary south of the region Thursday into Thursday night. The low pressure center moves across Friday and then east of the region Friday night. Weak high pressure briefly builds in Saturday before another low moves across Sunday. Weak offshore high pressure establishes for early next week.

NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/
Made only minor adjustments into the overnight based on passed hourly trends.

Patchy fog expected for Eastern Long Island and SE Connecticut where surface flow late tonight becomes more SE and these locations will be the last within the local forecast region to receive more steady rainfall showers.

Weak offshore high pressure moves farther into the western Atlantic as a mid-level shortwave over the Great Lakes approaches from the west. Light onshore flow will aid in the moistening of the BL and prevent temperatures from dropping too low. Low temperatures tonight will be in the 50s regionwide where lower 50s are more likely for areas east and upper 50s to near 60 will be more likely for the NYC metro and surrounding areas.

A line of convection associated with the shortwave over the Midwest/Ohio Valley will begin to make its way into the area overnight and into the early morning on Wednesday. This will result in the increasing chance for showers with embedded thunderstorms overnight into early Wednesday morning, with highest likelihood for this activity from SW CT, Western Long Island and NYC west through NE NJ and the Lower Hudson Valley.

SHORT TERM /6 AM WEDNESDAY MORNING THROUGH THURSDAY/
The batch of convective debris from the remnants of upstream storms will continue to make its way through the area during the morning. These showers and embedded storms will largely exit the area by mid to late morning, allowing for clearing into the afternoon for areas to the west. Clearing skies will allow for a rapid warming of the surface as strong heating takes over behind the departing showers. The timing and quickness of the clearing will depend on how far east the warmth will get. As of now, highs for the western areas like the Lower Hudson Valley, northeast NJ, and the NYC metro will be in the middle 70s to middle 80s. A relatively sharp gradient in high temperatures will occur where eastern areas may only sees highs in the low to middle 60s.

As the shortwave approaches the area into the afternoon, heights fall as a weak trough moves overhead. Steepening lapse rates combined with the strong surface heating will allow for the development of moderate instability, generally 500-1500 J/kg MUCAPE, over much of the area by late afternoon. Despite the instability, a mid-level cap is expected to prohibit widespread storm development.
Forcing for ascent appears to be limited to closer to the shortwave up to the north. As such, kept coverage of showers and storms into the afternoon at slight chance to chance, with a better chance of seeing convection for areas further north and west.

If convection develops, storms may become strong to locally severe with the primary threats being damaging wind gusts and hail. SPC has the area in a marginal risk for severe storms but threat diminishes in more stable and cooler air closer to the coast and further east where less surface heating takes place during the day and instability will be elevated as opposed to surface-based.

The chance for storms diminishes after sunset with the remainder of the overnight period being fairly dry, though a moist BL may allow for the development of low stratus and fog. Lows will once again be in the low 50s east to upper 50s west.

LONG TERM /THURSDAY NIGHT THROUGH MONDAY/
Upper levels exhibit active jet stream pattern across the region Thursday through Friday. Then the jet is positioned more to the south of the region for the weekend and into early next week.

Mid levels convey a southward moving wide trough that gets closer Thursday into Friday, bringing the area more positive vorticity advection in the process. The same pattern generally remains going through the weekend, with the trough moving farther east of the region early next week.

At the surface, low pressure approaches the region Thursday into Thursday night along a front south of the region. Model differences still present with progression of the surface low, some more recent model runs of NAM and GFS keeping low pressure west of the region by early Friday whereas ECMWF and Canadian keep low pressure farther east.

The low pressure center moves across Friday and then shifts farther east of the region for Friday night. High pressure then briefly builds in Saturday but will be quite transient, quickly giving way to another approaching low from the north and west Saturday night. The low moves in Sunday and Sunday night but will be of weak magnitude. Weak high pressure establishes offshore for early next week.

Rain showers are in the forecast much of the time Thursday through Friday night with the next main chance of rain showers Saturday night through Sunday. Mainly dry conditions are forecast thereafter.

Some of the rain showers Thursday into Thursday evening could be moderate to possibly heavy. Thunderstorms are possible Sunday into Sunday night with cold pool aloft moving in with the upper level trough.

Forecast high temperatures near normal Thursday, more below normal Friday, and then near normal for the weekend. Potentially more above normal temperatures could occur for early next week.
However, there is uncertainty.

AVIATION /03Z WEDNESDAY THROUGH SUNDAY/
A warm front lifts through the region late overnight and into Wednesday morning. A cold front moves through the region late Wednesday and Wednesday night.

VFR until late tonight, or toward Wednesday sunrise. However, with timing uncertainties conditions may lower a couple of hours earlier. Showers develop with the approach of a warm front, and shortwave energy moving through the upper midwest, toward Wednesday morning with conditions lowering to IFR, and possibly LIFR for a few hours as the warm front moves slowly through the terminals. Isolated thunderstorms are possible Wednesday morning, however, the chances are low and not included in the forecast. Conditions improve back to VFR with the warm front passage. Isolated showers and maybe a thunderstorm will be possible Wednesday afternoon into the early evening with the passage of the cold front. However, chances and confidence too low to include at this time.

Winds remain light south to southeast overnight, and light and variable in a few locations. Winds increase from the south to southwest ahead of a cold front, and then become westerly and gusty, up to 20kt, behind the front. Gusts may be briefly higher with the initial cold frontal passage.

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

Timing uncertainties with the lowering conditions late tonight, and may be a couple hours earlier than forecast. There is a low chance of isolated thunderstorms early Wednesday morning.

Low chance of SHRA or TS Wed afternoon, too low to include in TAF at this time.

OUTLOOK FOR 00Z THURSDAY THROUGH SUNDAY...

Wednesday night: VFR, except MVFR in fog at KGON. A slight chance of thunderstorms early in the evening east of the NYC terminals.

Thursday: MVFR/IFR. Showers likely, especially in the afternoon and at night.

Friday: MVFR/VFR with chance of showers.

Saturday: Chance of showers with MVFR cond at KSWF, otherwise VFR. Chance of showers at night with MVFR.

Sunday: MVFR/IFR with a chance of showers and possibly a thunderstorm.

MARINE
Winds and seas are expected to remain below SCA conditions through Wednesday night as seas will essentially average close to 3 ft.

Long term from Thursday through the weekend, sub-SCA conditions forecast for non-ocean marine zones but on the ocean, potential for SCA conditions due to seas. SCA seas forecast on the ocean at times mainly between Thursday night through the weekend.

HYDROLOGY
Minor nuisance flooding possible with rain showers Thursday into Thursday evening. WPC contains much of the region in a marginal risk for excessive rainfall for Thursday into Thursday evening.

TIDES/COASTAL FLOODING
Astronomical tides run high the next several days with a new moon tonight.

Minor flood benchmarks are likely to be exceeded during the evening high tide cycles tonight through Thursday across coastal southern Nassau, Queens, and Fairfield counties with inundation up to a foot. Localized moderate flooding is possible during Wed and Thu evening's high tides, particularly in the most vulnerable spots of southern Nassau and Queens.

Elsewhere, localized minor flooding for this evening's high tide in coastal Westchester, Brookyln, and northern Nassau/Queens.
Inundation up to a half foot is possible. Additional minor flooding is possible thru Thursday evening.

OKX WATCHES/WARNINGS/ADVISORIES
CT...Coastal Flood Advisory until 2 AM EDT Wednesday for CTZ009.
NY...None.
NJ...None.
