SYNOPSIS
High pressure builds into the area and remains in place through Thursday. A series of weak low pressure systems will produce chances for precipitation Friday, Sunday, and early next week.

NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/
An upper level shortwave pushes through the area this evening allowing for any residual snow showers in the area this afternoon and evening to dissipate shortly after sunset. At the surface, high pressure builds in from the southwest as a large low pressure system to the northeast over Southeast Canada pushes further away from the area. This will continue to allow for a tight pressure gradient through the overnight period. A brisk W/WNW flow advects some of the coldest air seen thus far this season into the area.

Low temperatures tonight will be in the lower to middle 20s for much of the area. The NYC metro will see temperatures around 30.

SHORT TERM /6 AM WEDNESDAY MORNING THROUGH WEDNESDAY NIGHT/
High pressure continues to build into the area on Wednesday with mostly sunny skies and dry conditions expected. While the pressure gradient slowly relaxes, a brisk W/WNW wind at 10-15 mph with some gusts up to 20 mph will continue to advect cool air into the area. As a result, high temperatures during the day on Wednesday will only rise into the middle to upper 30s for much of the area. Some areas along the coast may near 40 degrees, about 10 degrees below average.

Another cold night is expected Wednesday night with lows in the low to middle 20s for much of the area. Coastal areas and the NYC metro should drop to around freezing.



LONG TERM /THURSDAY THROUGH TUESDAY/
A warming trend on Thu as a weak thermal ridge builds in and the flow aloft flattens. This will result in a 10 degree jump in temps from Wed. The NBM was used.

A srn stream wave moves thru on Fri. The modeling is in pretty good agreement with this feature. This should produce a round of rain across the area, ending by Sat mrng per the 12Z guidance. The sys is progressive and lacks strong advection, so mainly a lgt to mdt rain swath is expected attm.

There is a chance for some shwrs or lgt rain on Sat with swly flow aloft. However, chances are relatively low with mid lvl dry air to overcome. Pops are in the 20 percent range for Sat.

Mild Fri and Sat and the NBM was used. Highs in the 40s to around 50 expected attm.

Continued mild on Sun with highs still in the 40s and 50s. A nrn stream trof begins to dig down on Sun, allowing weak low pres to develop off the coast. This sys will result in chances for rain on Sun.

The upr trof may dig into the region Mon and Tue, allowing another low to take shape. Model uncertainty is high this far out, so the consensus approach with the NBM was used. However, there is the potential for this portion of the fcst to turn out colder, with perhaps some wintry pcpn at least across the interior.

AVIATION /21Z TUESDAY THROUGH SUNDAY/
High pressure slowly builds in from the west.

VFR through the TAF period. A chance of light snow showers/flurries though 29/00z. Chances of any obstructions to visibility and MVFR ceilings are low.

West winds around 20kt with gusts 25-30kt slowly diminish this evening and early tonight. West winds around 10 kt expected on Wednesday.

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

Gusts of at least 30kt for KJFK/KLGA/KEWR will be most likely during the period of through 29/00z. During this same period, KTEB could occasionally gust to 30kt. Isolated gusts possible overnight but winds are expected to diminish.

OUTLOOK FOR 18Z WEDNESDAY THROUGH SUNDAY...

18z Wed-Thu: VFR.

Fri: VFR in the morning, MVFR or lower in rain in the afternoon and night.

Sat: VFR.

Sun. Chance of rain or showers. MVFR or lower possible.

MARINE
A gale warning remains on the ocean waters through tonight with gusts upwards of 35-40 kt expected. Small craft advisories also continue for the sheltered and non-ocean waters tonight with gusts upwards of 30 kt. The pressure gradient relaxes a bit on Wednesday to allow for conditions to drop below gale force.
Small craft conditions will be likely on the ocean with gusts near 25 kt during the day and seas near 5 feet. Non- ocean waters should largely remain below small craft conditions but an occasional 25 kt gust can't be ruled out. Seas may allow small craft advisories conditions to continue on the ocean through Wednesday night.

Mrgnl sca seas on the ocean Thu thru Sat, otherwise, winds blw sca lvl on all waters. Some stronger nely winds possible on Sun as low pres develops in the ocean. A sca for all waters is possible.
Conditions improve on Mon behind the sys.

There are no hydrologic concerns through Tuesday of next week.
