Recent National Weather Service and NOAA model guidance highlights a lingering frontal system and associated moisture pooling driving scattered showers and thunderstorms across the Midwest, Ohio Valley, Mid-Atlantic, and Southeast on September 21, 2026, with elevated precipitation probabilities tied to daytime heating and instability. Official forecasts note continued excessive rainfall risk in saturated areas from prior convection, while the Northeast sees lingering clouds and isolated activity before clearing trends. These patterns align with typical early-fall frontal passages, though ensemble spreads in GFS and ECMWF runs introduce uncertainty in exact rainfall totals and boundaries. Traders should monitor the next NWS short-range forecast discussion and updated quantitative precipitation forecasts, which will refine local probabilities ahead of market 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.
