The number of tornadoes in our area tends to peak May 25-June 5 in our viewing area as a whole.

However, the southwest counties tend to see the peak first & the north & northeast last.

Although the sheer number of tornadoes tends to peak in this period, the the most violent tornadoes have occurred in April to early May area-wide.

The area that seems to have the greatest number of tornado watches per year is deep in Dixie Alley.  There, Tornado Watches occur in the Late Fall, Winter to early Spring & then again with landfalling hurricanes in Summer to early Fall.  This increases the overall number of such watches there.

In our area Warren & Tippecanoe counties have averaged the greatest number of Tornado Watches, at least in the 1993-2012 period.

This deep Dixie Alley tends to have the greatest number of Tornado Warnings per year.

Central Oklahoma & Kansas see the greatest number of Severe T'Storm Watches per year in the 1993-2012 dataset.

However, note the Corn Belt/Prairie Peninsula higher frequency of Severe T'Storm Watches from Iowa to Central Illinois, Indiana & Ohio where there are a high number of MCSs, derechos in Summer & frequent squall lines in Spring & Fall.

In terms of severe t'storms, the average period to get damaging winds (1955-2014) is 5-6 p.m.

This map shows the average minutes in Severe T'Storm Warnings on average per year.

In the 1994-2013 period, Newton, Fulton, Miami counties averaged the greatest number of minutes in Severe T'Storm Warning.
