| Area Forecast Discussion National Weather Service New York NY 135pm EDT Sat September 5 2026 .WHAT HAS CHANGED... No significant changes. .KEY MESSAGES... 1) Conditions turn cooler and more comfortable for the holiday weekend. A few showers remain possible this afternoon and evening, mainly across southern Connecticut and Long Island. 2) After a tranquil stretch of weather early next week, unsettled conditions return Wednesday. .KEY MESSAGE 1... Closed low trough centered over the Canadian Maritimes digs into the Northeast to start the holiday weekend. Meanwhile, surface high pressure slowly builds south from Canada, ushering in a drier, cooler air mass. A mix of sun and clouds expected afternoon with the steep low level lapse rates from the cold pool(a region of relatively cold air) aloft and cyclonic flow. In addition, a spoke of energy pivoting around the digging trough rotates in from the north and east, likely helping to instigate scattered shower activity later this afternoon. Hi res guidance continues to place the bulk of coverage across S CT, before drifting south and west into the early evening hours. Despite the drier environment, a locally heavy downpour or two can't be ruled out, but thunderstorms appear unlikely given the profiles. The activity should begin to dissipate after sunset, though a few remnant showers could drift linger into the evening. Not everyone will see wet weather and many farther west likely remain entirely dry. Today will be the warmest of the weekend, though cooler than the past several days. H850 temps forecast 10-12C should yield highs within a couple of degrees of 80, on par with climatology for early September. And with the dry northerly flow, dew pts have fallen into the upper 50s and low 60s, which will feel noticeably less humid and much more comfortable compared to recent days. Sunday offers a taste of early autumn as temperatures and dew pts continue to fall. Highs on Sunday likely top out in the low to mid 70s for most, with continued lower humidity. Dry conditions prevail with no rain expected, but diurnal cu returns with the lingering trough. Labor Day morning likely starts cool and crisp, with some 40s possible in the coldest locales, mainly far interior and LI Pine Barrens, and 50s elsewhere. Opted to blend in the cooler MAV/MET data given the potential for efficient radiative cooling that could allow many to fall below national blended guidance. Temperatures rebound into the 70s to around 80 in the afternoon, with abundant sunshine and low humidity expected. .KEY MESSAGE 2... Surface high pressure continues to settle overhead through Tuesday, maintaining dry weather and light flow. Temperatures gradually warm with ridging aloft building in from the west and afternoon highs get back into the 80s. By midweek, SW flow develops well ahead of an approaching frontal system and conditions begin to turn more unstable and offer the next chance for rain in the forecast period. At this point, it's too early to discuss specific hazards, but periods of showers and thunderstorms are possible in the late Wednesday into Thursday timeframe. Marine Winds and seas are expected to remain below Small Craft Advisory criteria through Tuesday. Thereafter, SW winds increase ahead of an approaching frontal system. Wind gusts on the coastal waters may begin to exceed SCA (Small Craft Advisory) criteria (25 kt) Wednesday afternoon, which could linger through Thursday. Gale conditions are possible during this time, particularly on the ocean. Ocean seas likely build to 5-8 ft as well. These conditions could linger into at least part of Thursday before subsiding. Rip Currents A lack of significant wind or swell will lead to a low rip current risk through at least Sunday. NOAA New York NY Office: Watches - Warnings - Advisories CT...None. NY...None. NJ...None.
