Hoosier Posted April 19, 2016 Share Posted April 19, 2016 Beat me to it (was going to post tomorrow). I used to have a radar loop but I don't have it anymore. Guess I could throw one together. Link to comment Share on other sites More sharing options...
Hoosier Posted April 19, 2016 Share Posted April 19, 2016 This one was pretty impressive in terms of numbers. Not sure if it still holds the record for Illinois or if something has passed it since then. There were something like 69 tornadoes in the subforum area with over 50 of those occurring in Illinois and Indiana. Link to comment Share on other sites More sharing options...
Sidewinder Posted April 19, 2016 Share Posted April 19, 2016 I created an animation of the storm that rolled through our county 20 years ago. I had made a lengthy post previously here or the old western forum, search won't go back farther than a year. This storm did damage in other Indiana counties, and there were injuries in ours (Johnson). A barber shop, domino's pizza and Hampton's Market were destroyed.

SchaumburgStormer Posted April 19, 2016 Share Posted April 19, 2016 I was nine and saw my first tornado. My parents were on I-72 west of Decatur with a flat tire. My pops ended up driving on it until we were able to get north. Also was able to see a funnel the day before, don't remember too much about it other than the fact I saw a concrete gas station garbage can flipping end over end down the street. Really the event that sparked a young interest in weather. Link to comment Share on other sites More sharing options...

RCNYILWX Posted April 20, 2016 Share Posted April 20, 2016 23z-01z. 01z-03z. Incredible radar loops. Thanks for sharing them. Tsnow12 did an excellent talk on this event at COD a few years ago, titled something like 'April 19, 1996: When the Dryline Came to Illinois'Regarding the soundings Hoosier posted, the directional shear was excellent, but had the low level speed shear been stronger resulting in higher 0-1/0-3 SRH, there easily could have been multiple violent tornadoes. This was something pointed out in the COD talk. Link to comment Share on other sites More sharing options...

This was something pointed out in the COD talk. Considering where some of these supercells tracked, that would've likely been a catastrophe.

Hoosier Posted April 20, 2016 Share Posted April 20, 2016 Although this was a pretty prolific outbreak, a lot of these tornadoes were fairly short lived. Sort of surprising how nothing managed to stay on the ground really long. Link to comment Share on other sites More sharing options...
