Official National Weather Service climatological reports for September 4, 2026, recorded measurable rainfall and thunderstorms across parts of the Gulf Coast and Midwest, with New Orleans logging 1.12 inches amid heavy rain and fog while Columbus, Ohio, saw 0.12 inches. These observations reflect typical late-summer convective patterns driven by high atmospheric moisture, daytime heating, and steering from weak steering currents rather than organized tropical systems. Trader consensus on outcomes such as Miami at high implied probability aligns with localized storm activity in Florida and the Southeast, where NHC and local NWS stations provide the authoritative daily precipitation totals used for market resolution. No further model runs or data releases remain before final verification.

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.
