Widespread heat and humidity across the eastern and central United States on September 5, 2026, is driving scattered afternoon and evening thunderstorms, with National Weather Service forecasts showing elevated probabilities of measurable precipitation in the Southeast, parts of the Midwest, and Northeast. High dew points and instability support convective development, while steering patterns and moisture from lingering fronts increase rain chances in those regions compared to drier conditions in the West and Southwest. NOAA and NWS model guidance emphasize hit-or-miss storm coverage rather than widespread systems, with PoP values varying sharply by location and timing. Updated local forecasts and radar observations through the evening will refine resolution criteria for any city-specific markets, as light or isolated showers could determine outcomes under typical measurement thresholds.

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.
