Scattered showers and thunderstorms driven by high humidity, daytime heating, and weak steering patterns represent the main factor shaping trader sentiment for rain locations on September 4. National Weather Service forecasts indicate 50-60% probabilities of precipitation across much of Florida and the Southeast, with similar chances in portions of the Midwest and Northeast tied to lingering moisture and afternoon instability, while the West and central Plains show mostly sunny conditions and PoP below 20%. Model consensus from recent GFS and ECMWF runs highlights localized convective activity rather than widespread systems, with resolution hinging on official station measurements of measurable rain at specific sites. Updated NWS briefings and next model cycles will provide the key data shifts traders monitor ahead of market close.

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.
