The 3/12/2006 supercells

Note: It may take a few seconds for the images to load.

Updated: 6/7/2006 to include list of supercells and tornadoes.

The association of the tornadoes with the individual supercells is based on the best available data, but may not necessarily be correct (especially with some of the evening and late Missouri supercells in close proximity where I did not save some of the radar data from individual sites). The tornado list is from the preliminary submissions to Storm Data and may be revised.

The map shows paths of four different tornadic supercells from the March 12-13 outbreak. However, this shows the paths of only four of the apparently 12 tornado-producing storms. The tornado paths displayed are listed below as the "North Twin" storm, the "South Twin" (Springfield IL) storm, the Springfield MO storm (Evening MO Storm #5) storm, and the "Oklahoma-Arkansas" storm. The naming convention is just what I made up to help me keep things organized - this is in no way any kind of official name.

This map shows the storms from first echo to where the individual storm could not be tracked as an entity. The "width" displayed is when the storm was displaying supercell characteristics and shows the width from the base of the hook to the top of the notch. The storm with the longest path began losing supercell characteristics in northern Indiana, but continued to be identified to the Jackson MI area. Although continuity was more difficult as it moved NE from near Jackson MI as it interacted with additional thunderstorms, there appeared to be some evidence of the storm until it moved offshore over Lake Huron.
