Dewpoints were way up in the upper 60's and lower 70's with CAPE estimated at over 5000 J/kg. The shear was pretty evident as you can see from these leaning turkey towers. Charles is Rain-X'ing the windshield in anticipation of a good chase.

In this picture, Jim Leonard, Keith Brown and RJ Evans watch the sky.

We headed out that way oin Rte. 277 towards Haskell. Just north of town we observed a nice mesocyclone with curving inflow bands. It tried to form a wall cloud, but got undercut by a surge of outflow from the precip core.

This outflow kicked up a lot of dirt.

Here is a RealPlayer time-lapse movie of this meso. Rotation is very evident!

A bit east of Throckmorton, we watched a rapidly rotating wall cloud form directly overhead. I could really see the funnel in its center rotating.

The wall cloud really began to wrap up drawing in ragged clouds. A small dust whirl formed briefly below this funnel shortly after this photo was taken.

We were treated to a fantastic gold-backlit sunset.
