Overview

After cooler than normal days due to cloud cover across the Panhandles after a cold front pushed through, sunshine broke through the clouds and allowed for adequate instability and shear to develop and support severe thunderstorms. Thunderstorms developed in a moisture-rich upslope regime in southeast Colorado and then moved south into the western OK panhandle. A thunderstorm moved south out of Colorado and dropped a couple brief tornadoes in Cimarron County, OK and then proceeded to move south across the Texas Panhandle. As the storm moved south, it dropped baseball size hail in Dalhart, TX.  Other thunderstorms developed nearby and started to congeal with the original storm into a line of storms before moving through Amarillo and the southern TX Panhandle. Before leaving the TX Panhandle, some of the stronger segments dropped 70 to 80 mph winds.
