Current National Weather Service and NOAA guidance highlights a frontal boundary and associated moisture advection as the main drivers of precipitation chances across the eastern and southeastern United States on September 21. Scattered showers and thunderstorms are expected with 50-80% probabilities noted in the Mid-Atlantic, Northeast, and Florida regions, where localized heavy downpours remain possible. Model consensus shows lower rain chances farther west and in the interior, consistent with steering patterns and limited instability. Traders monitor updated short-range guidance and official probability of precipitation maps, which can shift quickly with new observational data or model runs ahead of the daily resolution criteria for measurable precipitation at specific city stations.

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.
