303 FXUS61 KOKX 240000 AFDOKXArea Forecast Discussion National Weather Service New York NY 800 PM EDT Tue Sep 23 2025
.SYNOPSIS... Offshore high pressure will shift farther out into the Atlantic through tonight while a cold front approaches from the north. The front will settle over or just south of the area late tonight into Wednesday night. The front will lift north of the area Wednesday night into Thursday as weak low pressure passes well to the west. A trailing cold front will remain nearby from Friday into Saturday. A second cold front will move across on Sunday, followed by high pressure for Monday and Tuesday.
&&
.NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/... Showers with embedded thunderstorms will be pushing into NE NJ and the Lower Hudson valley this evening. Radar obs show gusts have likely remained below 35-40 mph so far in these storms, and with instability waning and winds aloft not too supportive, not expecting any severe gusts with these storms. Thunderstorm potential will remain into the overnight hours, but mainly isolated in nature. Showers in general spread east across the forecast area through the night, but becoming less in total coverage as the night wears on. Brief heavy downpours still possible, but just looking at brief nuisance flooding in urban and poor drainage areas as impacts. Patchy fog could also develop especially after midnight.
&&
.SHORT TERM /6 AM WEDNESDAY MORNING THROUGH THURSDAY/... The cold front should sag just south of the area on Wed and remain nearly stationary into Wed evening, then lift northward again as a warm front later Wed night as weak low pressure passes W of the Appalachians. Chances for showers and possibly a tstm continue into daytime Wed, then more widespread shower/tstm activity expected for Wed night into Thu as the front lifts northward late Wed night into Thu morning, then Thu afternoon as another cold front approaches.
&&
.LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/... NBM was followed with no changes.
Key Points:
* A slow moving area of low pressure, and cold front, is expected to impact the region Friday and Saturday. A second cold front follows on Sunday.
* Chances of showers persist through the weekend.
* Drier conditions expected Sunday into the first part of next week as high pressure builds back into the region.
* Daytime temperatures will be near to slightly above normal Friday through Monday, with highs in the 70s. Nighttime lows will be above normal Friday night and Saturday night, and return to more normal levels Sunday night and Monday night.

.AVIATION /00Z WEDNESDAY THROUGH SUNDAY/... A cold front from the north moves into the region late tonight and becomes stationary across the area on Wednesday.
VFR early this evening, but MVFR will be possible with any showers and thunderstorms tonight, then even outside of showers late tonight, especially away from the city terminals, but still went with TEMPO MVFR cigs in the city during the Weds morning push. Still cannot completely rule out a thunderstorm tonight, but not enough probability for a mention in the TAFs.
Chance of showers and thunderstorms late afternoon into the evening, mainly to the north of the NYC and LI terminals.
SW-S winds 10 kt or less will go light and variable late tonight. Mainly E to SE winds at 10 kt or less for Weds.
...NY Metro (KEWR/KLGA/KJFK/KTEB) TAF Uncertainty...
TEMPO MVFR cigs might not occur during the Weds morning push, but it is still possible for prevailing MVFR cigs.
.OUTLOOK FOR 00Z THURSDAY THROUGH SATURDAY...
Wednesday night through Saturday: Periods of MVFR with showers possible. Isold tstms possible at times.

.MARINE... SCA continues on the ocean waters given long period swells up to 5 ft associated with distant Hurricane Gabrielle. These elevated seas should persist into at least Wed afternoon.
&&
.HYDROLOGY... Showers/tstms ahead of a cold front could produce downpours with brief nuisance flooding in urban and poor drainage locales, mainly across interior portions of the Lower Hudson Valley and SW Connecticut tonight evening, also possibly across SE CT and the forks of Long Island late tonight. Antecedent conditions have been notably dry though, so the risk for flash flooding is low.
More widespread rainfall of 1-2 inches is likely from late Wed afternoon into Thu night. This does not appear to warrant flood concerns more than the possibility of localized minor issues.
&&
.TIDES/COASTAL FLOODING... A high rip current risk continues into Wed as long period 4-5 ft SE swell continues from distant Hurricane Gabrielle. The risk should lower to moderate on Thu as ocean seas subside.
&&
.OKX WATCHES/WARNINGS/ADVISORIES... CT...None. NY...High Risk for Rip Currents through Wednesday evening for NYZ075-080- 081-178-179. NJ...None. MARINE...Small Craft Advisory until 6 PM EDT Wednesday for ANZ350-353. Small Craft Advisory until noon EDT Wednesday for ANZ355.
