|
The first section contains radar and satellite imagery of the
thunderstorm which produced the Williamson County tornado. The first two
radar images were taken at 3:00 and 3:10 p.m. CDT respectively from the St.
Louis WSR-57. The second two images are enlarged copies of the first two
images for easier viewing. The final radar image is a loop of the third
and fourth images. The strongest storm in the center of the image is the
storm that produced the first reported tornado touchdown west-northwest of
Carterville, Illinois at 3:05 p.m. CDT. Below the radar images are
satellite pictures from 2:30 and 3:30 p.m. CDT respectively. All these
images are from the files of Dennis McCarthy, Regional Director of National
Weather Service, Central Region Headquarters.

This section contains impressive photographs of the actual
tornado, shown as it moved east along Illinois Route 13 toward Marion. The
left three pictures were shot from the southern portion of Herrin, Illinois,
looking south-southeast toward Route 13. They were provided by Bill May,
Herrin businessman and resident, and member of A.R.E.S. (Amateur Radio Emergency
Services) when these pictures were taken. The picture on the right is a
close-up shot of the tornado, looking southeast toward Marion from the Illinois
Route 13 exit of Interstate 57. While the identity of the person who took
this picture is unknown, Don Fisher, Marion businessman and resident, now has
the ownership rights to this photograph, and gave the National Weather Service
permission to use this picture.
