Today marks the 21st anniversary of the deadly tornado outbreak that hit Indiana on June 2, 1990. The National Weather Service confirmed 37 tornadoes that day, a record for Indiana, with a total of 65 tornadoes through parts of the Midwest and Ohio Valley. 7 of the tornadoes were rated “F4” with winds estimated at greater than 207 mph.
Check out this video from YouTube of the Petersburg, Indiana Tornado on YouTube that killed 7 in Petersburg.
May 30th was the anniversary of the 2nd largest tornado outbreak in the Hoosier state. 23 tornadoes were reported in that storm system. The third largest outbreak for the state was the “Super Outbreak” of April 3-4, 1974 with 21 tornadoes in Indiana. The “Super Outbreak,” however, is the largest nationwide outbreak, with a total of 147 tornadoes reported in 13 states.
This year, we’ve already had 24 tornadoes in Indiana, which not only puts us above the year-t0-date average of 9 tornadoes, it also beats the annual average (1950-2010) of 23.5. And nationwide preliminary statistics from the Storm Prediction Center show 1425 tornado reports year-to-date. That’s well above the annual average, but since those numbers are preliminary, it’s too soon to say if 2011 will go down as a record tornado season. It sure has been an incredible season for large, deadly tornadoes. Tuscaloosa,Minneapolis, Joplin, Oklahoma City, and Springfield, MA are just some of the hard-hit areas in this season that shows no signs of quieting down.
Here in Central Indiana, our next chance of severe storms comes Saturday. The Storm Prediction Center has placed us in a “slight risk” for severe storms. I think the chances are 30% or less of storms, but if you have plans late Saturday afternoon/evening keep in mind the chance of a few storms.
Before then, you’ll also be greeted by the return of heat and humidity! After a cooler/drier/less humid Thursday, we’ll head back into the 80s tomorrow and 90s on Saturday!
