At its peak
it was rated an F4 on the Fujita Scale.
Out of all the videos taken of this tornado
the most famous came from a local sheriff, Randy Stubblefield
who used his dashboard camera to videotape the twister.
At one point in the video
the tornado lifted and hurled a van and a couple of flattened pick-up trucks into the air.

Significant Tornado Parameter
?
VORTEX reports from experienced spotters indicated the Allison tornado was one of the biggest and meanest appearing tornadoes they had ever seen.
All sighting reports would place this as an F5 tornado
but due to little interaction with man made structures
the heavy rains and lapsed time to see the site
F4 was as high a rating as could be awarded.
