An upper-level low and slow-moving frontal boundary are driving scattered showers and thunderstorms across the eastern U.S. on September 21, 2026, with the highest probabilities concentrated in the Mid-Atlantic, Northeast, and parts of the Southeast according to National Weather Service and Weather Prediction Center guidance. Official forecasts show 60-90% chances of measurable precipitation in areas like the mid-Atlantic states through the day and night, supported by deep moisture and weak shortwave energy, while the central and western U.S. remain drier. Model consensus from NOAA indicates potential for locally heavy rainfall where instability peaks in the afternoon, though exact placement carries typical short-range forecast uncertainty. Updated WPC QPF products and NWS briefings expected later today will refine 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.
