Hold the left mouse button down as you drag the slider above the image (or use the arrow buttons) to fade between the GOES-8 visible image and the corresponding GOES-8 10.7 micrometer IR image at 23:45 UTC on 28 March 2000. Shadowing from overshooting cloud tops (visible) and an "enhanced-v" cloud top signature (IR) were evident at this time, about a half hour prior to the tornado in downtown Ft. Worth Texas (station identifier KFTW).
