You can still check on the archived SPC mesoanalysis page for a few more days. Then you'll have to go to this site to view CONUS sized views of them. 0-1 km EHIs maxed out at 11-12 and pretty much followed along with the Tuscaloosa-Birmingham supercell during the peak hours of the event. There was quite a gradient around it, though. In far northern AL, 0-1 km EHIs were only about 2-5. 0-3 km EHIs maxed out at 15-16 in C/N MS early in the event and actually decreased slightly to 13-14 as the Tuscaloosa-Birmingham supercell was hitting those cities. Again, there was a sharp gradient away from the axis of highest values there.Anyone know what the EHI values were prior to this event?
