Caught at least the last several minutes of the Norman tornado this evening about 3 miles east of my apartment on OK-9. I had originally gone out to sample the hail after watching the cell explode on radar, and fortunately had TDWR data on GR3 - from one volume scan to the next, I went from wondering if I'd be able to find any quarters in the storm to flying to the nearest hilltop to find the obvious tornado.
I first saw the tornado at approximately 0334 UTC, but it may well have been on the ground before that (in fact, based on the first TDWR velocity scan I saw, I bet it was). Though lightning was not frequent enough for me to see very well with the naked eye, it appears from the stills I shot that it was likely on the ground until about 0340 UTC. I watched in amazement during and immediately leading up to the ropeout as the tornado moved west - probably by at least half a mile - despite the storm motion being SE. With little precip in the immediate vicinity, this probably would have been a beauty with a little daylight, but I'll take it as it was, considering my last tube was March 26.
Unfortunately, given the lack of lightning, I had to shoot at ISO1600 and even then the exposures were too dark, so these stills are quite noisy and very contrast-enhanced - mainly just to give an idea of what it looked like.
EDIT: I just went out briefly to hunt for damage. For any locals interested, I found trees and fences down in three locations:
1) Along 48th Ave. about 0.2 mi. N of Lindsey St. (or 0.8 mi. S of Alameda)
2) Along Highland Hills Dr., in the subdivision bounded by 48th/36th/Lindsey/Alameda
3) Along 36th Ave. about 0.4 mi. N of Lindsey St. (or 0.6 mi. S of Alameda)
I'm sure the NWS survey will shed more light on exactly what happened. Should be one of their easier surveys in recent memory, as the damage is literally a 10-minute drive from the NWC.
