Current atmospheric patterns, including moisture advection and instability ahead of a frontal boundary, are driving scattered showers and thunderstorms across portions of the eastern and central U.S. on August 21, 2026, with National Weather Service forecasts indicating 60-90% precipitation chances and localized heavy rain in the Mid-Atlantic and Midwest. Official NWS and WPC guidance highlights model consensus on diurnal heating fueling convective activity, though exact locations remain sensitive to steering flow and timing of any mesoscale systems. Traders should monitor real-time radar, updated NWS short-term forecasts, and NOAA precipitation discussions for shifts in coverage or intensity that could alter resolution outcomes before the day's end. Historical August climatology shows typical convective patterns in these regions, underscoring the role of current conditions over long-term averages.

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 KBOS.This market will resolve to "Yes" if New Orleans, LA records measurable precipitation on August 21, 2026. Otherwise, this market will resolve to "No".
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 KMSY: midnight to midnight local standard time. The final CLI report for a climate day is issued the following morning.

The resolution source for this market is the NWS Daily Climate Report (CLI) for KSFO.Current atmospheric patterns, including moisture advection and instability ahead of a frontal boundary, are driving scattered showers and thunderstorms across portions of the eastern and central U.S. on August 21, 2026, with National Weather Service forecasts indicating 60-90% precipitation chances and localized heavy rain in the Mid-Atlantic and Midwest. Official NWS and WPC guidance highlights model consensus on diurnal heating fueling convective activity, though exact locations remain sensitive to steering flow and timing of any mesoscale systems. Traders should monitor real-time radar, updated NWS short-term forecasts, and NOAA precipitation discussions for shifts in coverage or intensity that could alter resolution outcomes before the day's end. Historical August climatology shows typical convective patterns in these regions, underscoring the role of current conditions over long-term averages.
