Wow!  Some detailed stuff re the frequency of severe storms of 2007 in the US and some other neat info for those of us who feed on information!!  Click on the alternate tabs for hail, winds etc on the US map and the mind boggles at the area that received each specific event - that's just not possible surely...but it was!

Mike,

A couple of interesting points come to mind immediately:

- the region of the Texas Panhandle and south central Kansas really dominated this year - some serious tornadoes including Greensburg and the many tornadoes on that day as well as the following day.

- eastern Colorado had one of their better tornado years - which happens from time to time (apparently 1993 was another year when this also occurred)

- note how there is a sharp decline in reports west of the tornado alley states. I know there is a lower population density but generally severe weather is far less frequent in these regions.

Regards,

Yes, Jimmy for sure.  I should look at the past reports of previous years for a comparison, but the differences are mind boggling.  Just about half of the entire US experienced large hail and wind damage and the majority of those were not associated with tornadoes.   Texas with a 187 tornado figure which is pretty impressive.  The figures put into perspective the rationale of tornadoes are rare beasts given the number of active days listed and the amount of tornadoes reported.  Some days are in the 500's, yet only a small proportion of those storms produced tornadoes.  Goes to show that as you have experienced, you can have many, many supercells but no funnels produced.
