| Area Forecast Discussion National Weather Service New York NY 1031pm EDT Monday August 10 2026 .WHAT HAS CHANGED... No significant changes since the last update. .KEY MESSAGES... 1) The heat and humidity lowers slightly into mid week, followed by a more meaningful drop late week. 2) Thunderstorm chances lower Tuesday and Wed, followed by an increase in the thunderstorm chance on Thu. 3) Minor coastal flooding possible for some areas during the middle of this week. .KEY MESSAGE 1... A slight drop in humidity levels should commence Tuesday. Also temperatures are expected overall to be a degree or two lower during the day. This should lead to heat indices across a large majority of the area to fall short of heat criteria, although a few locations mainly across southern portions of the area may flirt very briefly with heat criteria (heat index of 95) for an hour or two. Therefore heat headlines will not be carried into Tuesday. A more meaningful drop in the humidity levels are anticipated into Wednesday morning. With temperatures and dew point readings forecast to be even lower on Wednesday heat indices are forecast to be mainly 85 to 90. On Thursday heat indices are expected to be on either side of 90. Therefore at this time heat headlines are not anticipated for the remainder of the week as a more meaningful drop in humidity levels takes place Friday into Saturday. .KEY MESSAGE 2... For Tuesday into Wednesday forcing appears minimal around convective chances. Shortwaves currently are forecast (via NWP (Numerical Weather Prediction) and AI) to stay just to the south. If shortwave energy gets further north then convective chances would increase. Otherwise, the convective chances increase into Thursday as heigheights begin to fall some and cyclonic curvature increases in the mid levels, and thus the greater chance of late day and evening convection. .KEY MESSAGE 3... Astronomical tides will increase with an approaching new moon on Wednesday. Winds don't appear to be much of a factor with the evening/nighttime high tide cycles tonight through Wednesday night when minor flooding would be possible. A blend of 50th percentile NAEFS-based PETSS and NYHOPS seemed reasonable given recent trends. Flooding is therefore not anticipated tonight, but levels should come close to minor benchmarks for the south shore bays of Nassau County and Queens as well as Southern Fairfield County. With the astronomical tide a little higher Tuesday night, a Coastal Flood Statement could be needed for these areas. A better chance of an advisory would be during Wednesday night for these spots as flooding would be more widespread, and other spots including parts of NY Harbor and more of Western LI Sound could reach minor benchmarks as well. Marine Winds and seas are expected to remain below SCA (Small Craft Advisory) levels this week. Ocean wave heigheights are not expected to exceed 3 ft or so. A more northerly component to the prevailing wind direction is expected towards Friday and Friday night. Rip Currents Waves around 2 ft this week and winds generally 10 kt or less will likely keep the rip risk low through Wednesday. NOAA New York NY Office: Watches - Warnings - Advisories CT...None.
