April 30th
Missed the El Reno tornado by a few minutes.
Left fairly early and sat in Kingfisher for quite a while letting the atmosphere destabilize. The outflow from the morning convection was too cold to support tornadic storms, and the cold front was gradually shifting SEWD toward us, thus only a narrow area of instability. It sure was nice to have solid mid 60s dewpoints though! The other big problem of the day was decreasing mid to upper level flow, which typically makes for HP cells and screwed up storm structure.
Finally saw some good TCU farther SW thanks to my laptop connection, so we sent SW toward the cell in Caddo/Grady county. This cell had a very strong VIL core on it, but started raining into itself. About this time, guys on the radio simulcast were going bonkers about a tornado near El Reno. Granted, it was a nice little tornado, but not "violent" like they were saying. Drove up the turnpike only to see a dissipating wall cloud. Great instability profile on the OUN sounding at 00Z but the shear was lacking, otherwise it could have been quite a day.
