Current National Weather Service and NOAA guidance shows scattered to widespread showers and thunderstorms across the Northeast, Midwest, and parts of the Ohio Valley on September 20, driven by a slow-moving frontal boundary and anomalously high precipitable water values. Moderate excessive rainfall risk persists over eastern Iowa, northern Illinois, and northern Indiana, with 1–3 inches possible in localized areas. In contrast, much of the South, Southwest, and northern High Plains remain mostly sunny or only partly cloudy with lower probabilities. Short-range model consensus and radar trends indicate the primary rain axis will shift slowly eastward through the day, while drier air builds from the west. Updated NWS forecasts and QPF products issued overnight will provide the final resolution inputs for any location-specific markets.

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.
