National Weather Service forecasts for September 23, 2026, show scattered showers and thunderstorms possible across portions of the eastern and southern United States, driven by lingering atmospheric moisture, weak frontal boundaries, and daytime heating that favors convective development. Probability of precipitation values range from 20-50% in many areas per NWS grids, with higher chances in parts of the South and lower odds farther north or west; quantitative precipitation forecasts remain modest outside organized cells. These patterns align with typical late-September climatology of isolated to scattered activity rather than widespread systems. Traders should monitor updated model runs and real-time radar for localized intensification, as measurable rain (>0.01 inch) at specific NWS stations determines resolution.

Measurable precipitation means 0.01 inches or more as reported by the PRECIPITATION (IN) figure in the NWS Daily Climate Report (CLI) for the city's station.
A report of trace ("T") does not qualify.
The PRECIPITATION (IN) figure measures total liquid-equivalent precipitation and does not distinguish between precipitation types.
The observation period is the NWS climate day for KNYC: midnight to midnight local standard time. The final CLI report for a climate day is issued the following morning.
This market will resolve according to the NWS Daily Climate Report as published by 2:00 PM ET on the day following the observation date. If multiple versions of the report are issued, the last version published before that time governs. If no figure has been published by that time, this market will resolve to "No".
The resolution source for this market is the NWS Daily Climate Report (CLI) for KNYC, published at https://forecast.weather.gov/product.php?site=NWS&product=CLI&issuedby=NYC.
