Current NOAA and National Weather Service forecasts for September 22, 2026, show regionally variable precipitation chances driven by a mix of frontal boundaries, lingering moisture, and developing low-pressure systems. The National Weather Service highlights higher probabilities of rain and thunderstorms across parts of the Midwest, Northeast, and Southeast, with PoP values ranging from 20-80% depending on location and timing, while drier conditions are expected in portions of the central Plains. In the Bay of Bengal region, the India Meteorological Department notes an intensifying low-pressure area likely to deliver heavy rainfall to coastal West Bengal and adjacent areas. Traders should monitor updated model runs and NWS short-range forecasts, as steering patterns and convective development can shift outcomes rapidly 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.
