A weather system featuring upper-level energy and associated fronts is driving showers and thunderstorms across the central and eastern United States on September 19, 2026, with the National Weather Service Weather Prediction Center highlighting a moderate risk of excessive rainfall over parts of the Upper Great Lakes into the Middle Mississippi Valley. Official forecasts show 70% or higher precipitation probabilities in areas such as eastern Iowa, northern Illinois, and southern Wisconsin, alongside scattered afternoon thunderstorms in Florida (around 40% daytime chance) and minimal odds in the Northeast like New York (near 2%). Model consensus from sources including the HREF and GEFS supports localized heavy totals exceeding 2–3 inches in the Midwest risk zone, consistent with typical late-summer convective patterns. Traders should monitor updated NWS quantitative precipitation forecasts and local office briefings for any shifts in steering or intensity before resolution.

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.
