A LOOK AT SOME AWOS SITES ARND CWA SHOW LOW CLDS(BKN-OVC010) ON NRN
PLATEAU.  LAWRENCEBURG ALSO HAS SOME BKN CLDS AT 5K.  ALSO EXPECT
CONSIDERABLE CLDS FROM THE DECAYING MCS IN MO/AR.  WOULD PREFER PARTLY
SUNNY TO CURRENT WORDING.  ALSO TEMPS ON SRN PLATEAU ARE IN LINE WITH
ZN GRP 8 INSTEAD OF GRP 7.  WOULD LIKE TO MOVE COFFEE-WARREN-BLEDSOE AND
S IN WITH GRP 8.

AND JUST FOR YOUR INFO...WE MODIFIED THE SOUNDING FOR A HIGH OF 86/DWPT
69 AND ALSO ADJUSTED UPPER LVLS AS PER UPPER AIR MAPS.  THIS GAVE US
ABOUT -8 LI AND CAPE OF 2600 J/KG.  BUT THERE WAS A DECENT CAP IF THE
TEMPS AT H8 WARM THE 2-3 DEGS IT LOOKS LIKE THEY MIGHT.  IF NOT...WELL
IT COULD BE A REAL FRIDAY THE 13TH.
