This loop presents 30-second interval Visible imagery from GOES-8, focusing on thunderstorms in extreme eastern CO and western KS. Note the rapid changes in individual cloud appearance, and changes in the nearby cumulus fields that occur from image-to-image. Also notice the feature that appears within one minute, twenty-five seconds (00:01:25) on the southeast flank of the western-most storm complex (last two frames). This is a low-level stratocumulus shield associated with a thunderstorm outflow boundary. Wind gusts of 70 mph were reported at the ground at this time.
