FXUS61 KOKX 081754 AFDOKX Area Forecast Discussion National Weather Service New York NY 154 PM EDT Wed Jul 8 2026 .WHAT HAS CHANGED... No significant changes to forecast. && .KEY MESSAGES... 1) Gradual warming trend through the end of the week. 2) Showers and thunderstorms are possible both Thursday and Friday afternoon and evenings. 3) Mainly dry conditions for the upcoming weekend with seasonably warm temperatures. && .DISCUSSION... .KEY MESSAGE 1... Low pressure moves into the open Atlantic today, while weak high pressure slides southwest of the region, allowing for dry conditions expected through Thursday morning. Temperatures will be slightly below average with highs in the upper 70s to low 80s. The high pressure will shift to the southeast and offshore on Thursday. Temperatures will continue to moderate with highs reaching near seasonable levels in the lower to middle 80s. The warmest day of forecast period will likely be Friday. Highs could come close to 90 degrees in the NYC metro and NE NJ with most other spots reaching the upper 80s. Max heat indices should reach the low to mid 90s. Temperatures/heat indices will be lower for the weekend behind a cold front passage. The forecast heat indices on Friday are below the 1 day heat advisory criteria (100-104 for any length of time). .KEY MESSAGE 2... A weak shortwave aloft is forecast to pass across the northeast on Thursday. At the surface, a trough of low pressure is likely to set up across the area. The combination of these features supports the potential for showers and thunderstorms in the afternoon and evening. Modeling has differed in the placement of the focus for convection, but current consensus indicates the highest probabilities across the southern half of the area including the NYC metro, NE NJ, and Lower Hudson Valley. Showers/storms that develop in the afternoon may gradually work east towards southern CT and Long Island in the evening. CAPE values are not too impressive with forecast soundings indicating 1000-1500 J/KG of SBCAPE away from any sea breeze influence. 0-6km shear is weak with on average of about 20 kt. This should limit severe potential and SPC currently only has the area in a general thunderstorm risk for Day 2/Thursday. A slightly more amplified shortwave trough axis is expected to pass across the northeast on Friday. This system should drag a cold front through the area late Friday into Friday night. The system will bring potential for another round of showers and thunderstorms Friday afternoon and early evening. The latest model consensus brings the highest probabilities to areas north and west of the NYC metro. Shear is a bit stronger averaging around 25-30 kt with similar CAPE valued as Thursday. Specific details on any severe weather threat are uncertain since this is still 3 days out, but CSU MLP does indicate a marginal probability for a severe thunderstorm. PWATs are progged to range from 1.75-2.00 inches both days. Some lingering MVFR at KGON through about 12Z.It is too early to determine if there will be any flooding impacts and WPC currently does not have the area in an excessive rainfall outlook. However, given the high moisture content, any thunderstorm can produce heavy rainfall rates. .KEY MESSAGE 3... The ensemble mean synoptic pattern across the CONUS indicates ridging across the west and NW flow/troughing over the east and Western Atlantic. This pattern should keep conditions mainly dry through the weekend with temperatures near seasonably warm levels. The general synoptic pattern could persist into early next week with only a slight uptick in temperatures. && .AVIATION /18Z WEDNESDAY THROUGH MONDAY/... Mainly VFR conditions are expected through Thursday afternoon. Scattered showersand thunderstorms will be possible Thursday afternoon at the NYC area terminals, as well as at KSWF. PROB30 groups were maintained during the timeframe where TSRA is most likely, which is generally between 18Z and 22Z Thursday, depending on location (on the earlier side for the terminals farther to the west; on the later side to the east). Winds are shifting to S/SW this afternoon at less than 10kts and will remain that way through Thursday afternoon. Winds pick up slightly at 10-15kts Thursday afternoon, with locally higher gusts in any thunderstorms. ...NY Metro (KEWR/KLGA/KJFK/KTEB) TAF Uncertainty... No unscheduled amendments expected. .OUTLOOK FOR 18Z THURSDAY THROUGH MONDAY... Thursday afternoon through Friday: Mainly VFR. Chance of afternoon and evening showers and thunderstorms each day with brief MVFR to IFR conditions possible. Saturday through Monday: VFR. && .MARINE... SCA remains in effect on the ocean waters east of Moriches Inlet through 2 pm due to lingering 4-5 ft seas. Seas will diminish on all waters today with high pressure returning. A frontal system passes across the waters late Friday into Friday night. Conditions should remain below SCA levels through the upcoming weekend. Rip Currents: A moderate risk of rip currents persists through Friday, due to a mixture of 1-3 ft S wind wave and lingering 1-3 ft SE/E swells. && .OKX WATCHES/WARNINGS/ADVISORIES... CT...None.
