SYNOPSIS. A cold front moves through tonight with a secondary cold front will moving through Friday afternoon. High pressure builds in thereafter through Saturday. The next frontal system and associated low pressure approach on Sunday, moving across Sunday night. The front becomes stationary offshore on Monday as high pressure briefly returns. The front may move back to the west during the middle of next week.

NEAR TERM /UNTIL 6 AM FRIDAY MORNING/. Ahead of a vigorous shortwave trough approaching from the west, some showers and isolated thunderstorms have developed. Most of the instability has been to the south of the area in New Jersey so as the shortwave trough approaches, light to moderate stratiform rain is likely for several hours with embedded heavier downpours and thunderstorms. Though the threat of severe weather has diminished a bit from this morning, a strong to severe thunderstorm can't be entirely ruled out this evening. The primary threat of any strong to severe thunderstorms will be heavy rain and gusty winds, though an isolated tornado still cannot be ruled out as there is ample low level helicity.

With PWATs on the increase over the last few hours, values of 1.5 - 1.7 inches will result in the potential of locally heavy rainfall. Generally, anywhere from 0.5 - 1 inch of rainfall is expected with locally high amounts up to 2 inches in any more persistent downpours. Any showers and thunderstorms should end after midnight tonight.

As the shortwave trough moves through tonight and the cold front passes, a brisk NW flow will develop behind the front tonight bringing in generally drier conditions. Lows tonight will be in the upper 60s and low 70s.

SHORT TERM /6 AM FRIDAY MORNING THROUGH FRIDAY NIGHT/. A brisk NW flow behind the cold frontal passage will develop Friday morning with generally drier conditions as a high pressure system builds in from the west. With daytime heating and a secondary cold frontal passage moving through during the day, the lower atmosphere should become well mixed resulting in gusty winds of up to 30 - 35 mph through the afternoon and into the evening. Mostly clear skies through the day will allow temperatures to rise into the upper 70s and low 80s.

Dew points will be falling through the day as strong NW flow advects drier air into the area. Dew points by the evening will likely be in the 50s for much of the area and with clear skies from an approaching high pressure system, some radiational cooling overnight into Saturday morning is possible though a steady wind may prevent significant cooling. Lows will be below average with temperature dropping into the 50s for much of the Interior and low 60s along the coast. Some spots in the Interior may drop into the upper 40s.

LONG TERM /SATURDAY THROUGH THURSDAY/. Mean upper troughing will be in place for the upcoming weekend. Saturday continues to shape up to be a seasonably cool day with temperatures in the middle and upper 70s and dew points falling into the 40s to around 50. Temperatures could reach 80 degrees in the NYC metro and NE NJ urban corridor. These readings are a bit below normal for this time of year.

The next within the upper trough dives out of southern Canada on Sunday, moving across the Great Lakes region in the morning and afternoon. This energy carves out a shortwave that lifts across New England Sunday night. The associated frontal system approaches during the day and then moves across Sunday night. Have gone below NBM PoPs due to uncertainties in the mesoscale. Global models continue to struggle with potential convective development and any convectively induced vort maxes. This will be important to determining where any wave of low pressure forms along the front. Instability is not impressive, but have left in mention of thunder for now.

The front will be offshore on Monday, but likely become stationary as western Atlantic ridging strengthens. This should adjust the location of the upper trough axis, pushing it across the Ohio Valley down to the southeast late Monday into Tuesday. There are also indications the jet stream flow will become split with the northern stream becoming situated over southern Canada. The southern stream remaining over the eastern states may continue carving out troughing. These features are all uncertain giving the time range and have followed the NBM closely during the middle of next week. The amplification of the western Atlantic ridge will play an important role in how much the frontal boundary retrogrades west. Waves of low pressure could ride along the boundary, but specific details are uncertain at this time. Temperatures should trend close to normal next week.

AVIATION /20Z THURSDAY THROUGH TUESDAY/. A warm front approaches from the southwest and a frontal system pushes through the area this evening.

Showers and thunderstorms will impact the terminals late this afternoon and evening through 02z. Gusty winds and heavy rainfall are the primary threat which will bring varying ceiling conditions in and around storms. MVFR/IFR cigs expected overnight tonight with isolated showers possible through midnight.

Mainly S-SE flow 10-15 kt for coastal terminals will continue through the evening with gusts to 15 kt. Uncertainty on wind direction this evening especially in and around thunderstorms.

West north west winds 5-10 kts overnight could increase to 10-15kts with potential gusts Friday morning into the afternoon, possibly to 25 kt.

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

Showers and Thunderstorms through 02z could have MVFR to IFR conditions and wind gusts greater than what is currently indicated in the TAFs.

OUTLOOK FOR 21Z FRIDAY THROUGH TUESDAY. Friday. Mainly VFR. Slight chance of a shower. NW winds G25kt late day/evening. Saturday. VFR. Sunday. Mainly VFR with chance of showers . mainly at night. Monday. VFR. Tuesday. MVFR or lower with a chance of rain.

MARINE. SCA conditions are expected tonight on the ocean waters as wind gusts ahead of the approaching cold front will increase with gusts to 25-30 kt and waves rise to near 5 feet.

After a brief lull Friday morning, SCA conditions likely on all waters Fri afternoon/night after a secondary cold frontal passage, with gusts 25-30 kt, also ocean seas building to 4-6 ft. Conditions should fall below SCA criteria by Sat AM.

Sub-SCA conditions are likely Saturday through early next week with a relatively weak pressure gradient in place.

HYDROLOGY. There is the potential for up to 1 inch of rainfall this evening and tonight, with locally higher amounts possible. Minor urban and poor drainage flooding is possible.

TIDES/COASTAL FLOODING. A moderate risk of rip current development will develop at ocean beaches on Thursday due to building S wind waves and lingering SE swell. There is a moderate risk of rip current development at the ocean beaches again on Friday despite offshore flow, due to residual 3 ft S swell.
