Only have time to provide a few details and a couple poorly-processed photos...)
Amos Magliocco and I observed 3 tornadoes associated with the long-lived supercell from Hartley to Dumas to Stinnett, TX. In addition, very impressive structure was noted, especially after 7pm CDT.
Tornado A. Approximate location: 2 WSW Dumas. GPS time: 622 pm CDT. Developed just north of the main hook echo precipitation blob. Tornado was a slender condensed tube that appeared to move south, presumably rotating around the edge of a larger circulation.
Tornado B. Approximate location: 7 E Dumas. GPS time: 637-639 pm CDT. Condensed cone developed in an occluded region of the storm, near Hwy 152.
Tornado C. Approximate location: 4 NW Stinnett. GPS time: 738-743 pm CDT. Best-looking tornado we observed this day. Cone tornado developed on what appeared the forward flank notch of the updraft. Lasted for nearly 5 minutes before becoming shrouded in precipitation.
