I live in Broken Arrow and I remember a lot of sirens, but not much in the way of actual tornadoes touching down. I googled it, though, and came up with these:

April of 2006, a brief touchdown by a weak tornado occurred in northeast Tulsa. The weak twister caused some minor damage at the Tulsa International Airport and an adjacent hotel. The storm served as a reminder how unpredictable Tulsa weather can be.

One of the final tornadoes in the outbreak almost hit the studios of ABC affiliate KTUL-TV in Tulsa, located on Lookout Mountain, a few miles west of the city itself, at around 12:15 a.m. CDT on May 4. Then chief meteorologist Travis Meyer advised his co-workers to take shelter while still on the air reporting on the approaching tornado. It weakened before reaching the station.
