A low-pressure system and associated warm front, combined with high precipitable water values exceeding 2 inches along the I-95 corridor, drove scattered showers and thunderstorms across the Southeast and Mid-Atlantic on September 12, 2026. National Weather Service observations recorded measurable rainfall in Atlanta (thunderstorms noted) and portions of the Ohio Valley, while Miami saw lower totals amid more variable coverage. Model consensus from the HREF highlighted efficient warm-rain processes and localized heavy bands, consistent with climatological patterns for early-September moisture surges. Official NWS climate summaries and QPF discussions confirm these events as the key drivers behind market-implied probabilities for affected cities, with resolution hinging on station-specific daily totals.

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.
