Whew...this reminds me of working severe weather events when I interned with the NWS in Fort Worth. Time flies by.

New tornado (or same tornado, who knows?) on the ground near Chandler. Storm continues to move ENE along I-44. Storm is still 1-2 hours from the Tulsa area.

UPDATE: Storm has two reflectivity hooks now. Moderate velocity couplet with the eastern hook. Still a formidable supercell, but looking less organized.

UPDATE: Storm is starting to get very complicated. Tornado on the ground in or near Stroud.

UPDATE: Amos and Dave are still on the storm, keeping ahead by a few miles on I-44. They've been on it since it first started getting organized near Hobart. Tim Marshall and Gene and Karen Rhoden had a close brush with a tornado earlier near I-35 and Briton Rd. in NE OKC. Apparently, they ended up taking cover. The DOWs were nearby, so hopefully they were able to get some good data.

UPDATE: NWS Tulsa went ahead and pulled the trigger on the Tornado Warning for southern Tulsa County...that's close to an hour of lead time. Sirens already sounding in Tulsa neighborhoods. Here's hoping people are paying close attention. Storm has dual circulations now...not sure if either are producing a tornado at this moment. Amos is reporting major damage in Stroud.

UPDATE: Storm entering Tulsa County and accelerating some, taking on a strange appearance. Still has a TVS, though. Right now, it looks like the main circulation should pass south of Tulsa proper. With it going through some sort of transformation in appearance, though, nothing is guaranteed.
