Recent National Weather Service and Weather Prediction Center guidance highlights remnant tropical moisture from Tropical Depression Edouard interacting with a stalled frontal boundary and high precipitable water values, favoring scattered to widespread showers and thunderstorms across the Gulf Coast, Florida Peninsula, and parts of the southern Plains on September 3. An upper-level low and onshore flow will sustain convection in these areas, while a separate Pacific system drives measurable rain across western Washington and Oregon. In contrast, drier high-pressure influence limits chances over much of the central and northern U.S. Traders should monitor updated NWS short-range forecasts and WPC excessive rainfall outlooks, which resolve markets based on official 24-hour precipitation reports at specific stations or regions.

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.
