The severe thunderstorm over western Osage county is showing signs of increasing rotation on radar. No ground reports have been received as of yet, however radar indicates that a tornado could occur at any time. The circulation on radar (white circle on image below) is currently located very near Fairfax, and moving East to East/Northeast at 25-30 mph.
Remember, when looking at the velocity data (bottom image), reds show wind blowing away from the radar, and greens show wind blowing toward the radar. The radar site is located toward the right center of the screen (at the light blue "KINX").
Seek shelter if you are in the path of this storm. After passing Fairfax, it will generally be in rural areas between Fairfax/Gray Horse and Wynona to Pawhuska.
Other storms are developing further East along the old outflow boundary, very near Tulsa and to points East. None of this activity is severe as of yet, but could become so quickly...
