Regional atmospheric instability and moisture advection from a decaying frontal boundary are driving scattered showers and thunderstorms across the Midwest and Southeast on August 21, 2026, with National Weather Service guidance showing 40–80% precipitation probabilities in areas like Milwaukee and central Georgia tied to daytime heating and sufficient CAPE. Drier conditions prevail elsewhere under high pressure, including parts of the Northeast and Finger Lakes, where models indicate minimal convective development and near-zero measurable rain. Late-summer climatology supports isolated afternoon activity in humid air masses, while ongoing NWS radar and short-range model updates through evening will refine exact coverage and intensity thresholds relevant to market resolution.

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.
