**A frontal boundary and lingering moisture are driving scattered showers and thunderstorms across portions of the eastern and southern United States on September 22, 2026, with National Weather Service forecasts showing 40-70% precipitation chances in the Southeast and Florida tied to afternoon convective activity.** Cooler, drier air advancing from the north is limiting totals in the Northeast and Midwest, where patchy drizzle or light rain dominates under overcast skies and northeast winds. In the Rockies and Plains, isolated high-based storms are possible amid unstable lapse rates. NOAA and local NWS offices continue issuing updated short-range forecasts and QPF products through the evening, while longer-range models will refine steering patterns and moisture return for any residual activity overnight. Historical late-September patterns show elevated rain probabilities in the Southeast during transitional seasons, supporting current trader focus on regional resolution criteria.

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.
