Current National Weather Service and NOAA forecasts indicate scattered showers and thunderstorms are most likely across the Southeast, Gulf Coast, and parts of the Midwest and Northeast on September 15, driven by lingering summer moisture, weak frontal boundaries, and diurnal heating. Western and northern Plains regions show lower probabilities under drier high-pressure influence. Model consensus from recent runs supports above-normal precipitation chances for much of the eastern U.S. during the broader Sept. 15–21 window, though exact locations and totals remain sensitive to small shifts in steering patterns and instability. Updated local forecasts and radar trends tomorrow morning will provide the final resolution data for market outcomes.

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.
