Scattered thunderstorms driven by surface troughs, a mid-level disturbance over the Carolinas, and daytime heating amid high humidity are the main catalysts for precipitation today, August 21, 2026. National Weather Service and Storm Prediction Center outlooks highlight slight risks of severe storms with heavy rain across the central Plains, Midwest, lower Mississippi Valley, and Carolinas, while South Florida and parts of the Northeast face afternoon convective showers amid heat indices near 105°F. Tropical weather discussions from the National Hurricane Center note disorganized Atlantic activity but no immediate landfall threats. Short-term model runs and radar trends will refine exact rainfall footprints as cells develop through the afternoon and evening.

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.
