Official NWS climatological reports for September 4, 2026, indicate measurable precipitation at southern stations including 1.12 inches at New Orleans and smaller amounts or trace at some northeastern and mid-Atlantic sites such as Central Park (0.11 inches) and Washington National (trace). Many central and western locations recorded zero precipitation. These daily totals from primary NOAA stations directly determine market resolution for city-specific outcomes. Forecasters and traders monitor the timing of final non-preliminary data releases, as revisions can shift implied probabilities in lower-volume markets. Historical September patterns show scattered convective activity favoring the Gulf Coast and Southeast on such dates.

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 KMIA: 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 KMIA, published at https://forecast.weather.gov/product.php?site=NWS&product=CLI&issuedby=MIA.
