tornadotony Posted March 11, 2011 Share Posted March 11, 2011 3/11-3/12/06 was the first outbreak I tracked at Eastern, and it did not disappoint. Over the two day period, 73 tornadoes struck the central United States, with a majority in Missouri. 10 were killed and damage was about $200 million (that number on the map does not include damages in Springfield, IL). The first round of tornadoes was Saturday night across srn MO and wrn IL. This included the infamous St. Mary, MO, F3 that killed 2 people and traveled 54 miles. The second round of tornadoes was a shocker to everyone, occurring well N of the warm front Sunday morning when temps were in the mid-40s and dewpoints in the mid-upper 30s. The third round of tornadoes began about mid-afternoon off the dryline. These cells traveled exceptional distances, with one beginning in NE OK and ending in SE MI. This cell was responsible for the Springfield, IL, tornadoes. Now by the time sundown arrived, even though we had had several rounds of supercells with tornadoes, none were overly impressive in terms of impact, and some were not sure if the event was going to live up to its hype. Well, the main disturbance quickly put that talk to rest, forming an incredible string of pearls across Missouri and Oklahoma. Also on this map is the continuance of the afternoon supercells, as Mr. Fabulous impacts Springfield, IL, and points NE. More to come... Link to comment Share on other sites More sharing options...

Hoosier Posted March 11, 2011 Share Posted March 11, 2011 It was an impressive outbreak for sure. My top 2 memories are those tornadoes in the cold air and the extremely long tracked supercell that was responsible for the tornadoes in Springfield. That thing seemed like it would never quit...I believe there was a spotter report of a brief touchdown in Kentland (I remember seeing pics that showed a funnel) but it was never confirmed.

Chinook Posted March 24, 2011 Share Posted March 24, 2011 You can watch a radar loop of the 6-state supercell on Youtube. It's 5 years later. That was still one of the most amazing cells I've ever seen. Link to comment Share on other sites More sharing options...
Indystorm Posted March 25, 2011 Share Posted March 25, 2011 Yep, I remember tracking that supercell all day as it eventually came up over Kentland way where I was living at the time. And this was the best thread I ever started at the old Easternwx site that ended up having a record number of posts. Hoosier is correct in his memory of the supposed touchdown at Kentland.

thewxmann Posted March 25, 2011 Share Posted March 25, 2011 Twas a good event. Imagine how much worse it could have been if that main wave had come in a tad earlier and more negative-tilt. One of the bigger events I've watched in EUSWx history. Link to comment Share on other sites More sharing options...
Fred Gossage Posted March 25, 2011 Share Posted March 25, 2011 Twas a good event. Imagine how much worse it could have been if that main wave had come in a tad earlier and more negative-tilt. One of the bigger events I've watched in EUSWx history. Or had the dewpoints in the warm sector been a good 5 degrees or so higher. One of the issues we had with the earlier supercells was LCL heights. Link to comment Share on other sites More sharing options...
