26 April 2009

This was our second consecutive family chase to the same part of west central and NW OK. Tornado potential was greater than the previous day given stronger low-level shear and greater low-level moisture. However, early convection and some changes in the wind and moisture profiles by late afternoon led to a somewhat unusual decrease in tornado potential. We managed to get in position on the main tornadic storm just before it produced its first of 2-3 tornadoes near Roll, OK.

A diversion storm early in the afternoon to the NE of Clinton, OK. We wandered up to check out this weakening supercell on the way to our actual target area farther W/NW near the TX/OK border. This storm soon weakened as rear flank outflow became too st

After repositioning to just WNW of Roll, we observed a strongly rotating cloud base to our SSW. I decided to move back to the ESE to get out of the hail and the direct path of the mesocyclone, utlimately settling on a location halfway between Roll and Cr

The funnel cloud continued to develop into a classic tornado to our WNW where it crossed hwy 33 just S of Crawford, or about 2 miles to our WNW.

Wide angle view of the tornado and broader storm structure. Unfortunately for us, we quit paying attention to the faintly visible lowering to the right.

The tornado continued to our NW and N as it began to rope out. The trees and poor contrast masked our view of the new mesocyclone to the N of the tornado. As we moved back E to the hwy 33 and US 83 intersection, we guessed that the viewing time on the s

The original Roll supercell was eventually seeded by several other storms to its WSW, leading to the formation of a band of storms. Later, the southwestern-most storm evolved into a more discrete structure, as it passed to our NW near Camargo. This stor
