A meandering frontal boundary and associated upper-level low are driving scattered showers and thunderstorms across parts of the northern Plains, Midwest, lower Great Lakes, and Southeast on September 18, 2026, with NOAA and NWS forecasts indicating 50-100% precipitation probabilities and localized heavy rain risks in those zones due to elevated moisture and instability. High pressure and drier air maintain mostly clear or isolated-storm conditions across the southern Plains, Southwest, and much of the West, consistent with official outlooks showing minimal PoP values there. Model consensus from NWS products highlights steering patterns favoring eastward progression of the system, with afternoon heating enhancing convective activity in the East and South; real-time observations and updated short-range guidance will refine exact rainfall footprints for market 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.
