Current National Weather Service and NOAA model consensus points to limited widespread precipitation on August 21, 2026, driven by typical late-summer high-pressure dominance over much of the U.S. and dry subtropical air masses suppressing convection. Regional variations depend on localized moisture advection, diurnal heating, and weak frontal boundaries, with afternoon showers possible where CAPE exceeds 1,000 J/kg and dew points remain elevated. Official quantitative precipitation forecasts emphasize low probabilities outside convective hotspots, aligning with climatological baselines of 20–40% coverage in mid-latitude summer. Traders monitor real-time radar and updated short-range guidance through the evening for resolution thresholds tied to measurable rainfall at designated stations.

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.
Resolution is based on the station's first published precipitation figure for the day. Subsequent revisions or corrections to the published data will not be considered; the first published value is final. If no figure has been published by 11:59 PM ET on the day following the observation date, this market will resolve to "No".
The resolution source for this market is the NWS Daily Climate Report (CLI) for KNYC.
