From http://www.spc.noaa.gov/faq/tornado/#Climatology...

"What is tornado season? Tornado season usually means the peak period for
historical tornado reports in an area, when averaged over the history of
reports. There is a general northward shift in "tornado season" in the U.S.
from late winter through mid summer. The peak period for tornadoes in the
southern plains, for example, is during May into early June. On the Gulf
coast, it is earlier during the spring; in the northern plains and upper
Midwest, it is June or July. Remember: tornadoes can happen any time of year
if the conditions are right! If you want to know the tornado peak periods
for your area, Harold Brooks of NSSL has prepared numerous tornado
probability graphics, which include distribution during the year."
