Flash flooding in the Waco, Texas area
5-minute CONUS Sector GOES-19 (GOES-East) Infrared Window images combined with the Total Precipitable Water derived product in cloud-free regions (above) showed clusters of thunderstorms that produced heavy rainfall across parts of central Texas shortly after sunset on 14 June 2026. Significant flash flooding affected the Waco area — which temporarily closed a portion of Interstate 35 near Waco, stranding vehicles with a few water rescues being required. 1-hour precipitation amounts at Waco were as high as 1.68 inches.
Multiple Flood Advisories and Flash Flood Warnings were issued as the thunderstorms expanded eastward and southward across Central Texas (below) — for the Waco area, the initial Flash Flood Warning was issued at 0054 UTC.
The coldest cloud-top infrared brightness temperature exhibited by these thunderstorms was -81.03C at 0041 UTC (above) — according to a plot of rawinsonde data from Fort Worth (below), that temperature represented an altitude near the Maximum Parcel Level (MPL) of the Forecast Surface (FCST SFC) air parcel.
