487 FXUS61 KOKX 281520 AFDOKX Area Forecast Discussion National Weather Service New York NY 1120 AM EDT Thu May 28 2026 .WHAT HAS CHANGED... Raising SCA for this afternoon and early evening for NY Harbor where near shore gusts this afternoon should reach 25 knots. && .KEY MESSAGES... 1) Cooler for the end of the week with multiple disturbances dropping south across the Northeast through the first half of next week. 2) A moderate rip current risk continues Thursday into Friday. && .DISCUSSION... .KEY MESSAGE 1... A series of upper level disturbances dropping SE across ern Canada will carve out an upper trough across the Northeast into the Canadian Maritimes. The strongest of these will move across New England and drive a stronger cold front through Fri night. So after a warmer Thu/Fri with temps running a few degrees above normal, Sat will be noticeably cooler and almost brisk, with a NW wind gusting to 25-30 mph. Temps daytime Sat per MOS may not make it out of the 60s. Temps should recover somewhat on Sunday with highs 70-75 which is actually close to normal. An upper level low may stall over the Northeast and produce chances for showers and isolated thunderstorms Mon-Wed. Some of the modeling however suggests a more transitory pattern, producing lesser chances duration-wise. The blended approach was followed to account for the uncertainty this far out. .KEY MESSAGE 2... A moderate rip current risk continues Thursday into Friday with a residual 2-ft 7 to 8 sec SE swell lingering. && .AVIATION /15Z THURSDAY THROUGH MONDAY/... A weak surface trough moves across the area today. Behind it, high pressure builds in form the northwest. Mainly VFR, but brief MVFR possible in a shower this afternoon.

An isolated low-topped thunderstorm is possible, but unlikely. NW winds increase to 10-15 kt with gusts 20-25kt this afternoon. KGON may not gust as the pressure gradient across that area is weaker. A few terminals may see occasionally higher gusts. Winds diminish after 00Z. ...NY Metro (KEWR/KLGA/KJFK/KTEB) TAF Uncertainty...
