Latest NOAA and ECMWF model runs indicate scattered precipitation across parts of the eastern and central United States on September 20, driven by a slow-moving frontal boundary and lingering moisture from recent systems. Short-range forecasts emphasize high uncertainty in exact rainfall locations due to model spread on storm track and intensity, with guidance updates expected multiple times daily through the National Weather Service. Traders should monitor afternoon model cycles and radar trends for shifts in coverage, as even modest changes in steering flow can alter probabilities for specific regions. Historical September patterns show variable convective activity this time of year, underscoring the value of real-time observational data over longer-range outlooks.

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.
