| Brief Description: A quickly moving tornado tore a 10 mile path through southern Taylor County. This tornado hit the community of Tuscola, where it damaged the Jim Ned high school injuring two people. A strong upper level disturbance combined with a strong surface low pressure system moving across West Central Texas produced a significant squall line that moved through the entire San Angelo county warning area. This squall line was accompanied by 60 to 80 MPH winds which produced widespread damage, especially across the Big Country. Embedded within the squall line, were several Supercell thunderstorms which produced nine tornadoes within the San Angelo county warning area. | |||||||||||
