NOAA's latest excessive rainfall outlook assigns a marginal risk for parts of the Mid-Atlantic and New Mexico on September 21, driven by an upper-level disturbance interacting with lingering moisture and a frontal boundary. Official model guidance shows the highest probabilities of measurable rain and thunderstorms across the Southeast, Florida, and coastal Mid-Atlantic, where afternoon instability supports scattered to numerous showers with localized heavy totals possible. In contrast, the Midwest and Ohio Valley see waning chances as the main system shifts east, while the central Plains and Rockies remain mostly dry outside isolated convection. New short-range forecast updates from the Weather Prediction Center will refine placement and intensity 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.
