Re: Possible Severe Event - 4/30 to 5/3
KOTV in Tulsa has a storm spotter observing the tornado in Osage County.
It had gone through a cycle and actually lifted up a couple of times, but then has come back and he said that it may be turning more violent again with multi-vortexes. Also said that there was a large cone trying to descend from a wall cloud near the tornado on the ground.
Looks like it is over sparsely populated rangeland right now but town of Pawtuska (sp?) is in it's path in the next 1/2 hour or so.

Re: Possible Severe Event - 4/30 to 5/3
Pawhuska is a town of about 3,700 people.
KOTV spotter said there is a tornado on the ground and another area of circulation to west.
KOTV meterologists are noting a rightward trend in motion, say that it will bring the storm very, very close to Pawhuska.

Re: Possible Severe Event - 4/30 to 5/3
KOTV spotter has seen a series of power flashes, one for eastern circulation nearer to Pawhuska and others (4-5) with the circulation to the west. Several more as I'm typing this...
