Hold the left mouse button down as you drag the slider above the image (or use the arrow buttons) to fade between the GOES-11 visible channel and the corresponding GOES-11 10.7 micrometer IR image at 22:15 UTC (5:15 PM CDT) on 11 July 2000. Note the appearance of shadowing and texture on the visible image, indicating regions of overshooting thunderstorm tops. On the IR image, there are two distinct "Enhanced-V" signatures (west and south of Watertown, KATY), which often indicates convection that is producing or soon will produce severe weather. Preliminary locations of reports of severe weather at 22:15 UTC (+/- 5 minutes) are also plotted on the images (TORN=tornado; A100=hail of 1.00 inches in diameter; G70=wind gust of 70 knots). This tornado produced F2 damage near Madison, SD.
