National Weather Service forecasts and quantitative precipitation outlooks as of September 22 indicate the strongest signal for measurable rainfall on September 23 centers on central and eastern New Mexico, where a moderate risk of excessive rainfall persists amid elevated precipitable water values and favorable dynamics, supporting localized totals of 2–5 inches. Scattered to numerous thunderstorms are also favored across parts of the Southeast, including Florida and Tennessee, with 65–80% probability of showers in many areas. The Northeast and Mid-Atlantic face mostly dry conditions under northeast flow, with precipitation chances generally below 20%. Model consensus from the NWS and high-resolution guidance highlights steering patterns and moisture transport as key variables, with updates from the Weather Prediction Center expected to refine totals and boundaries ahead of 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.
