SYNOPSIS. A nearly stationary front south of Long Island gradually dissipates tonight into Friday. Otherwise, high pressure remains to the north and high weakens Friday. Low pressure well south of Long Island moves northeast within the Western Atlantic Friday night. The low passes well southeast of Long Island on Saturday, eventually moving southeast of the Canadian Maritimes on Sunday. A weakening cold front will move across the region Saturday into Saturday night with strong high pressure building in for Sunday through early next week. The high pressure area will start moving more offshore Tuesday into Wednesday of next week. A frontal system approaches midweek, moving near the region towards Wednesday night into Thursday.

NEAR TERM /UNTIL 6 AM FRIDAY MORNING/. The frontal boundary moved a little farther to the south Thursday afternoon, and across the region there is little surface based or mixed layer CAPE, and little instability. There as some weak energy forecast to move across the region tonight, so will maintain a slight chance of precipitation. And will continue with the coverage wording for showers.

The low off the southeast coast tracks slowly northward tonight, reaching to off the outer banks of North Carolina by Friday morning.

SHORT TERM /6 AM FRIDAY MORNING THROUGH FRIDAY NIGHT/. The frontal boundary south of the region dissipates during Friday. However, weak shortwave energy will be moving into the region, and surface daytime instability increases. So will keep slight chance probabilities most of the day, and chance inland in the afternoon., with scattered to isolated convection.

Models remain consistent with the low off the North Carolina coast Friday morning, tracking to the northeast later Friday and deepening late Friday into Friday night. The low still passes southeast of the 40N/70W benchmark late Friday night and continues to track northeast farther away from the region for the upcoming weekend.

LONG TERM /SATURDAY THROUGH THURSDAY/. Mid level flow transitions from zonal Saturday to NW Saturday night through Sunday. A mid level trough moves across Saturday night with strong ridging thereafter through the remainder of the weekend and through early next week.

At the surface, a weak cold front moves across Saturday night. Ahead of it, some positive vorticity advection aloft and surface instability will lead to a few showers and thunderstorms, mainly north and west of NYC where there will be more instability with relatively cooler temperatures aloft. Moisture will be quite a limiting factor so POPs for showers and thunderstorms are just low end chance to slight chance for Saturday afternoon into early evening. Saturday will be relatively the warmest day of the long term with higher 850mb temperatures and downslope mixing with northerly flow, which will make for relatively warmer temperatures towards the coastline. Highs are forecast to be mainly in the low to mid 80s.

The other surface feature to take notice of is a low offshore that has potential for tropical cyclone development according to the National Hurricane Center. The models indicate the center of the low will be southeast of the 40N/70W benchmark Saturday morning. Then the low will be moving northeast farther out into the Atlantic and eventually southeast of the Canadian Maritimes on Sunday with westerly steering flow aloft.

Dry weather prevails for the rest of the weekend and into next week with strong high pressure taking control as it builds in from the north. Northerly surface flow will make for a relatively cooler temperatures latter half of the weekend and into start of next week. Highs are mainly in the 70s for much of the region Sunday and Monday. Some rebound in temperatures is expected for Tuesday with more of a upper 70s to lower 80s range as the area gets more on the backside of the ridge with more southerly flow.

Towards midweek, next rain shower chances are in the forecast as a frontal system approaches from the west.

AVIATION /20Z THURSDAY THROUGH TUESDAY/. A stationary front remains south of Long Island thru Fri.

Sct shwrs and isold tstms possible thru 00Z, but coverage and probability were to low to pinpoint in the TAF. Because of this, VCSH has been included til 00-01Z. There are additional chances for shwrs and tstms tngt, but again the probability was too low to include in the TAFs. An isold shwr/tstm cannot be ruled out for Fri.

Cigs are expected to fall to MVFR into this eve and then IFR tngt. Conditions may remain IFR most of Fri, with improvement possible mainly aft 18Z. There could be some vis reductions tngt in br. 5sm vis has been included across wrn terminals attm.

Winds will generally be around 060-080 thru the TAF period.

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

Amendments possible for the timing of falling cigs this eve. Amendments will be required if shwrs and tstms are expected to become widespread this aftn and/or eve.

OUTLOOK FOR 18Z FRIDAY THROUGH TUESDAY. Rest of Friday. Improvement to MVFR or VFR, then potential for IFR overnight. Sat. Mainly VFR. A cold front could produce isold-sct shwrs. Winds shift to the N by late in the day. Sun. VFR with NW flow. Mon-Tue. MVFR possible at times.

Detailed information, including hourly TAF wind component forecasts, can be found at: https:/www.weather.gov/zny/n90

MARINE. Winds and seas remain below SCA levels tonight. As the pressure gradient increases late tonight into Friday, as a system off the southeast coast tracks north, ocean seas will build to 5 feet early Friday morning. Then with the low moving northeast Friday night ocean seas will continue to build, and ocean gusts will be near 25 kt, especially east of Moriches Inlet. A SCA has been issued for the ocean waters for Friday through Saturday.

SCA conditions are forecast to linger Saturday night on the ocean east of Fire Island Inlet which could continue into Sunday morning as well. Otherwise, expecting sub-SCA conditions eventually for all waters Sunday and through early next week as high pressure and a weak pressure gradient encompasses the waters.

HYDROLOGY. No hydrologic issues expected.

TIDES/COASTAL FLOODING. There will be a moderate risk of rip currents today for the ocean beaches with 2 to 3 ft ocean seas with residual southerly swell and E-SE winds of near 10 kt. For Friday, ocean seas will be building to 5 to 6 ft with more of an easterly swell and winds will be E-NE near 10-15 kt, making for a high risk of rip currents for the ocean beaches.
