SYNOPSIS. A strong cold front will move across the area this afternoon into early this evening. A frontal wave along the front will rapidly deepen, while passing to the west today, heading up into the Canadian Maritimes tonight into Thursday. At the same time, high pressure will build to the south and west of the area Thursday into Friday, passing offshore on Saturday. Low pressure approaches from the southwest Saturday night, passing just to the south on Sunday. High pressure then builds back into the area for the start of the new work week.

NEAR TERM /UNTIL 6 PM THIS EVENING/. Minor adjustments were made to account for the latest observations and trends in the near term.

A weak stationary front across the Lower Hudson Valley and interior SW CT will lift to the north quickly this morning as daytime heating mixes down a gusty southerly glow (25-30 mph). Initially, there will be sun this morning, which will allow temperatures across the interior to rise into the mid 60s, possibly around 70 just west of the NYC metro. This will allow some destabilization of the airmass ahead of a strong cold front approaching from the west. A vigorous upper trough over the Great Lakes will strengthen the boundary as it works east, along with a frontal wave that looks to pass near or just west of the Lower Hudson Valley this afternoon.

CAMs in good agreement with some pop-up showers this morning in association with 40-45 LLJ working up from the SW. This jet will mainly be along an axis from the NYC metro into SW CT, translating east by early afternoon. The main convective line along and ahead of the cold front will work into far western areas of the Lower Hudson Valley and NE NJ toward 18Z (2PM), then working across the remainder of the are mid to late afternoon, exiting far eastern LI and SE CT by around 00Z (8 PM).

SPC has placed a good portion of the forecast area under a slight risk for severe weather, with the exception eastern LI and SE CT. This is a low CAPE, high shear environment. General thoughts are that the line will weaken passing to the east of the NYC metro and Lower Hudson Valley/SW CT. The main threat will be isolated damaging winds. Soundings generally support small bowing line segments. 0-3 km helicity values approach 150. The best chance for an isolated tornado would be closer to the surface low track, but once gain CAPE is low.

Brief heavy rainfall may produce a quarter to half inch of rainfall as the line works across the area.

Following the cold front, strong cold advection and deep cyclonic flow will allow for good mixing and gusty west winds (up to 35 mph)

SHORT TERM /6 PM THIS EVENING THROUGH FRIDAY NIGHT/. Any lingering showers will pass to the east early this evening. Clearing skies and gusty west winds will prevail. This combined with an unseasonably cold night across the region will give a winter-like feel. Overnight lows across the interior will drop to around 30, with the lower to mid 30s elsewhere. The freeze watch for Western Passaic, Orange, Putnam, Fairfield, and northern Middlesex have been upgraded to a freeze warning. Ironically, today is considered the start date for the growing season across this area.

Gusty winds continue on Thursday as the low pressure strengthens while moving over the Canadian Maritimes. High pressure also builds to our south and west, creating a strong pressure gradient over the region. W-NW wind gusts 25 to 35 mph are likely, and could reach 40 mph near the coast. Highs on Thursday will be well below normal in the upper 40s inland to the lower 50s near the coast. Winds weaken some Thursday night, but should still remain gusty enough to preclude frost again. Lows will be in the middle to upper 30s for most locations.

High pressure will build to the south and west through Friday and then off the Mid Atlantic coast Saturday. Temperatures will moderate back to near normal levels.

LONG TERM /SATURDAY THROUGH TUESDAY/. High pressure to the south moves farther offshore on Saturday as an amplifying trough and associated surface low over the Mississippi Valley begin to approach the region. While clouds will increase, the daylight hours are expected to remain dry.

Precipitation rapidly overspreads the area Saturday night as the low approaches and then passes over or just south of the region during the day on Sunday. Rain then gradually tapers off from southwest to northeast Sunday afternoon. As the low moves off to the northeast, gusty northwest flow is expected Sunday night into Monday as high pressure begins to build in from the west. Dry conditions are expected Monday and Tuesday as the high becomes more established.

After above normal temperatures on Saturday, highs on Sunday and Monday are expected to remain near to slightly below normal as the low impacts the area. Above normal temperatures will then return on Tuesday with plenty of sunshine.

AVIATION /12Z WEDNESDAY THROUGH SUNDAY/. Low pressure passes west of the NYC terminals today, sending a strong cold front across the region this afternoon. High pressure then builds toward the area tonight into Thursday.

VFR this morning. A few showers could develop as early as 12-14Z ahead of the cold front, but not expecting any ceiling/visibility impact from these. A line of showers and thunderstorms then crosses the area between 17-23Z, with MVFR ceilings and IFR visibilities possible in any thunderstorms. The best chance of thunderstorms will be between 19-21Z for the city terminals. Conditions then quickly improve back to VFR this evening.

Southerly winds will increase this morning, gusting to 20-25 kt by mid- morning. As the front crosses the area this afternoon, winds will quickly shift to the NW and increase in speed, with gusts 30-35 kt possible through tonight. Gusts to over 40 kt are possible in any thunderstorms this afternoon.

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

Amendments are possible this afternoon for timing of showers/thunderstorms.

OUTLOOK FOR 12Z THURSDAY THROUGH SUNDAY. Thursday. VFR. WNW gusts 25-35kt. Friday. VFR. WNW gusts 20-25kt. Saturday. VFR. Saturday night-Sunday. MVFR/IFR in rain.

MARINE. S flow increases ahead of a strong cold front today, with SCA conditions on the ocean waters and on all waters by the afternoon. The cold front moves across the waters by evening. Gale Warning remains in effect on the ocean for frequent gusts over 34 knots tonight into Thursday. The SCA on the non ocean waters continues Wednesday night and will continue into Thursday.

Lingering SCA conditions likely on Friday in a gradually diminishing west flow, especially on the ocean.

Sub-SCA conditions are expected on Saturday before both winds and seas increase Saturday night into Sunday as low pressure crosses the waters. Gusts to 25 kt are possible on all waters, especially Sunday afternoon into Sunday night as flow turns to the northwest behind the departing low. Seas on the ocean will increase to 5 ft Sunday morning, then to 6-8 ft late Sunday into Sunday night.

FIRE WEATHER. Both Thursday and Friday may pose an elevated risk of wildfire spread due to low RH and gusty west winds. Rainfall amounts today will be on the order of 0.25 to 0.50 inches. This will likely factor into how quickly fine fuels can dry out. So, the greater risk may come on Friday. Land managers will be contacted today to discuss forecast fuel moisture during this time

HYDROLOGY. No hydrologic impacts are expected through the week.
