Moving to a high CAPE and DCAPE environment.  SPC Meso analysis has 5000/1700 for each.  Near cast model shows the region is fairly unstable.  Area under clear skies now.  12Z sounding had 12 kft freezing level as well as 8500 wbz.  PW of 0.67 is dry.  Have some cu over western Pennington that is blowing up now.  Seems region is unstable.  CI had a high value just before that cell went up.

The yellow area above did not blow up, but the next image below did go quickly…see following image as well.
