Early this evening, a large supercell thunderstorm turned southward and moved across Briscoe, Hall and Motley Counties accompained by very large hail up to tennis ball size and damaging straight-line winds. By late this night, scattered strong and severe storms organized farther west near the Texas and New Mexico state line and quickly flourished into a damaging squall line that raced east-southeast across the southern Texas Panhandle. Several reports of severe winds accompanied this squall line from Parmer County east to Childress County - the most severe of which involved 47 freight train cars derailing in far northeast Parmer County from winds determined to be as high as 100 mph.
