No.

...or frequency for that matter.
We need it broken down
by months to be of value. The Midwest does not get many T-storms in
the Winter, which is about 6 months of the year in Chicago.

Neither does Mobile, except when cold fronts pass.

On this same subject. Midwest tstorms are frequently 45k+ feet. Is
this common in other areas? From my aviation readings, I was lead to
believe that the Florida/Louisiana storms tend to top in the 30s, and
hence are less intense.

They vary, but the're almost always 45k'. Truly violent boomers
capable of producing property damage are not common in sunmmer, but
often accompany fronts in spring and fall.
