National Weather Service outlooks highlight elevated precipitation potential across the southern High Plains and Southwest on September 23, driven by a mid-level shortwave and subtropical moisture surge that favors organized thunderstorms and training cells over New Mexico and far west Texas. Official guidance assigns moderate excessive-rainfall risk in these areas, with model consensus supporting localized totals exceeding several inches where bands align. Elsewhere, probabilities remain lower: scattered afternoon showers are possible in parts of the Southeast and Midwest, while many northern and western locations trend drier under building high pressure. Forecasters emphasize that short-term model runs and radar trends through the evening of the 22nd will refine exact placement and intensity before the market resolves against official gauge or radar-derived observations.

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.
