Doswell has been busy of late with the historic March 18 Tri-State outbreak. Interesting reading once his new book comes out.
Some details came from the seminar are:
1. The tornado did not occur in the cold sector of the storm
2. The path of the low is incorrect on the old maps that were published in WeatherWise Magazine.
3. The tornado actually started one county earlier than previously thought.
4. The tornado was an F5.
5. There was a large outbreak of tornadoes on that day across the TN and Ohio Valleys. We may never know the full number of tornadoes that touched down. There were a significant number of F3 and F4 tornadoes in TN and KY.
6. They have discovered a strong outflow boundary that set up across KY and TN during the day of the event. This seems to be where a number of the large tornadoes eventually formed.
7. It appears that it may in fact have been a single tornado and not several !
8. A strong dry line swept all the way into West TN and West KY.
Here's a recent video of Doswell during an interview with a reporter at the seminar.
