Hoosier Posted October 18, 2011 Share Posted October 18, 2011 Already 4 years since this event occurred. It is one of the more impressive October outbreaks in recent memory with over 60 tornadoes, 17 of which were rated EF2/EF3.

Hoosier Posted October 18, 2011 Author Share Posted October 18, 2011 I thought there might've been a PDS tornado watch but looks like there wasn't according to the archives.

Stormhorn Posted October 19, 2011 Share Posted October 19, 2011 My buddy Bill and I chased in Indiana that day. We tracked a nice supercell from initiation. At one point it looked like it wanted to drop a tube so bad, it was about ready to pee its pants, but it never did. Just to our north, Nappannee got clobbered by an F3, but we missed that storm.

Stebo Posted October 20, 2011 Share Posted October 20, 2011 Me and Patrick7032 chased this day too, through Central Michigan, caught 2 funnel clouds and had we had stayed at the Williamston exit on I-96 we would have seen a tornado. We were there 40 mins before Williamston was hit with a EF-2, we were on the storm before that one which had a funnel cloud that passed just West of the exit there, and crossed I-96. This was one of our better chases and 90% of it came at night time. Link to comment Share on other sites More sharing options...
patrick7032 Posted October 20, 2011 Share Posted October 20, 2011 One unusual event at least where Stebo48858 and I were and likely occurred else where is areas that had been hit by convection got repetitively hit when you would expect a meso high/meso stable layer from that area being convective overturned. But you're right Hooiser, it was quite the storm. I remember Stebbo48858 and I looking at Bufkit data showing sfc-8km shear of 100 and sfc-6 of 85 and mesoanalysis showed that when it hit sfc-8m was 120 and sfc-6 was 95. Let alone getting 1000-1500 cape at that time of year in Michigan. I'd say that storm and the Oct. 2001 storms were the most memorable fall storms for me.

Can't believe it's already 10 years. Will probably do an anniversary post for that one. Link to comment Share on other sites More sharing options...
