A rare November tornado touches down in Oklahoma, and is captured by Basehunters weather chase team based out of Norman, Oklahoma.
Severe thunderstorms with a tornado outbreak were captured by videographers near the Blue Canyon Wind Farm northwest of Lawton, Oklahoma and northeast of the Wichita Mountains Wildlife Refuge.
Amazing video from the Basehunters weather chase team captured several tornado scenes. Once scene shows the tornado passing right through the Blue Canyon Wind Farm with little turbine blade movement observed. No report of damage to the windmills. At one point a Basehunter team member says something not heard very often during a tornado chase: A request to turn on the car window defroster.
No injuries were reported, but firefighters rescued people from flood homes in Murray County, about 75 miles east of Lawton, Oklahoma.

Thanks for using our video! Just a couple of factual corrections. The SPC graphic here is actually valid only until 6AM on 11/7, as it was the 01:00 UTC forecast. The correct graphic is here: http://www.spc.noaa.gov/products/outlook/archive/2011/day1otlk_20111107_1200.html. SPC did expect significant tornadoes on 11/7.
The other comment, we use the defroster quite often on chases. Not because of icing, but because windows fog up near storms because of abrupt temperature and humidity changes.
Isaac, Thanks for the comment and corrections. I had a feeling The Cardinal would get called out on the defroster statement. Great video.
