National Weather Service forecasts indicate widespread rain across the Northeast and parts of the Midwest on September 20, 2026, driven by a low-pressure system and associated cold front lifting northward. Official outlooks show periods of steady rain and embedded thunderstorms expected from the mid-Atlantic through New England, with rainfall totals of 0.5–1.5 inches and a marginal to slight risk of excessive amounts in urban areas; similar organized showers are projected over eastern Iowa, northern Illinois, and Indiana. Florida faces a 70% chance of afternoon thunderstorms tied to tropical moisture, while the southern Plains and Southwest remain largely dry under clearer conditions. Resolution will hinge on verified precipitation measurements from NWS stations, with model updates from the Weather Prediction Center providing the latest guidance on exact boundaries and intensities.

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.
