| Area Forecast Discussion National Weather Service New York NY 130pm EDT Wednesday August 5 2026 .WHAT HAS CHANGED... No significant changes .KEY MESSAGES... 1. Potential for scattered afternoon/early evening heavy downpour and thunderstorm activity from tonight into early next week. 2. Hot and very humid from Thursday into Monday, with the highest heat and humidity Thursday and Friday. .KEY MESSAGE 1... Potential for scattered diurnal convection should persist from tonight into early next week as region lies on the NW edge of Bermuda ridging, with shortwave energy riding up the ridge itself and then also approaching from the west this weekend into early next week as the ridge weakens. The ridge will help usher in a very warm and very humid air mass into the region Thu into early next week, with deep SW flow and H8 temps rising to 18-20C. Guidance depicts best forcing mainly south/west of NYC today. Additionally, not expecting any significant moisture advection (aside from the thin layer near the surface due to the sea breeze) until after sunset today. Current forecast carries only slight chance late day Probability of Precipitation for portions of NE NJ, then better chances tonight. As the moisture builds particularly from Thursday onward, this will present an isolated severe and flash flood threat, primarily in the afternoon and evening hours. Storm motions are expected to be moderate through this period (20-30 kt), so it may come down to whether will be any training of storms or if brief very heavy downpours occur over the most flood vulnerable locations. The WPC marginal risk of excessive rainfall for Thursday through Saturday is reasonable. The severe threat for Thu looks only marginal well inland. .KEY MESSAGE 2... Very warm and very humid for Thursday into the weekend. Temps on Thu/Fri should rise to at least to the upper 80s/lower 90s if not a little warmer in the urban corridor of NE NJ/NYC metro, with dewpoints in the mid 70s. This should yield widespread heat index values of 95+ across the entire CWA, and as high as 100-105 for NYC metro, coastal CT, and most of Long Island except the south fork and immediate south shore. MOS continues to run higher on temps and lower on dewpoints than NBM, but with similar heat index values. A heat advisory will be needed for this time frame. For Sat-Mon, heat index values should reach the mid/upper 90s across the NYC metro area and across most of Long Island and the I-95 corridor of southern CT. Marine Could see a period of winds/seas approaching 25 kt and 5 ft on the ocean waters W of Moriches Inlet from late day into the evening on Thu. Rip Currents A moderate rip current risk is expected for today as SSE swells continue to subside closer to 3 ft. The moderate risk should continue through most of Thursday, however it may increase to high at some beaches toward evening as southerly winds and swells increase.
