Brian Gotter: Welcome Back, Gotter

Tornado Season is Here

  • Print

Yesterday was the anniversary of the earliest tornado in Milwaukee’s recorded history back in 2000 when an EF1 formed on north side of airport and moved into St Francis.  Last week’s tornado outbreak in Kansas, Missouri, Illinois and Indiana reminded us tornado season is here, but to have that many tornadoes in a week in March and that violent, is rare. 

However, the deadly Tri-State tornado that also started in Missouri and went through southern Illinois was on March 18, 1925.  It was the deadliest tornado (695) until last year’s Alabama tornado outbreak in April.  

The country averages about 90 tornadoes in March and since 1844, Wisconsin has had only 18 twisters.  Tornadic activity increases across the country in April and even in Wisconsin with 117 tornadoes since 1844, May 236, June (the peak month) has had 430, July 325, and August has 196 recorded tornadoes.  September can still be active with 125 twisters, 30 in October, 9 in November, 6 in December and 3 in January.  February remains the only month without a recorded tornado in Wisconsin. 

2005 had the most twisters across the Badger state with 62 and last year had 38…15 of those were on April 10.  The average is 21. 

No tornadoes here this weekend but rain is possible Sunday afternoon.  Today will be sunny and in the upper 30s and back into the 50s on Saturday.
