April 15, 2000 Chase summary
This summary uses some pictures and some video captures.
Today's chase included myself, Robert, Shane, and Julie. We all met at my place in mid afternoon with a rather less than outstanding outlook on the afternoon's potential. The moisture was severely lacking and lack of clearing giving us less than ideal heating had resulted in pretty weak CAPEs in the 1000-1500 range over north Texas and the expected wind profile was poor. As we got into Vernon, we made the decision to drop south to make the storm west of Crowell the target. A good decision overall as we were able to get into a very good position on FM267 southwest of Thalia. We had an ideal view of the storm at it approached and watched the completely flat and featureless rain free base do nothing at all.
The storm was not looking all that strong.
Mammatus to the east....
We made a couple of wise retreats to the south (on 267 and later 1919) as the rather impressive green clouds would catch up with us in this outflow area "with a view." (right) 
Realizing that the storm we were watching was too far gone we headed toward Seymour and the better air, hoping to get information or a view of something happening further south and west. As we came back up 277 to the northeast, I decided we would stop at the intersection of 277 & 183 to watch for awhile since we were safely out of the hail area.
From there, the viewing was briefly interesting as what appeared to be an east-west oriented gust front stretched nearly the western horizon eastward and northeastward out of view presumably ended up back in Wichita Co. where the strongest storms were reported to be at that time. From there, we could also briefly get a nice view of a rain free base on a storm as yet producing little precip back over in Knox county. (below)
The decision was then made to move back toward Seymour, and watch to see if it developed. Perhaps the most amazing thing I've seen in quite some time occured as we approached seymour. There was little left between us and the sun setting to the west and the low sun angle was illuminating the bottom of the low clouds over our heads!
It was quite incredible and we of course stopped here to look and take pictures. Very good timing on our part the whole day to get many great views, be in a great position to view a rain free base, avoid all the hail, and only drive 270 miles. Overall, a very "chase"!
