246 PM CDT THU APR 10 1997

ATMOSPHERE CONTINUES TO DESTABILIZE ACROSS THE CWA WITH ADAP
INDICATING LI'S TO MINUS 6 WITH VERY LITTLE CAP IN A PLACE. FORECAST
SOUNDINGS ACROSS WEST TEXAS SUGGEST CAPES TO 2000-2500 J/KG PER
COORD WITH SPC. MEANWHILE DRYLINE IS CLOSE TO MTNS ATTM...HOWEVER
WINDS AT GDP AND DWPTS SUGGEST DRYLINE IS BEGINNING TO MOVE E AND
STILL EXPECT IT MOVE CLOSE TO MIDLAND BY EARLY EVENING. WARMEST
TEMPS ATTM ARE IN WINKLER COUNTY SUPPORTING VERTICALLY ENHANCED CU
FIELD AND BELIEVE IT IS JUST A SHORT MATTER OF TIME BEFORE TSTMS
BEGIN TO RAPIDLY DEVELOP IN THIS AREA. LOW CLOUDS STILL IN PLACE
ACROSS ERN HALF OF THE CWA AND CONVECTION IS LESS LIKELY ATTM AND
SPC HAS RECENTLY ISSUED A TORNADO WATCH. CONVECTIVE THREAT WILL BE
INCREASING FURTHER E HOWEVER AS CLOUDS ERODE ON WRN EDGE WITH
DRYLINE AND UPPER TROF AXIS APPROACHING. SCATTERED MENTION OF SEVERE
STILL WARRANTED TIL AROUND MIDNIGHT AS WINDS INCREASE ALOFT WITH
MID-LEVEL DRYING WORKING INTO THE RGN AND AS ETA IS STILL
FORECASTING CAPES TO 1500 J/KG BY 06Z. THEREAFTER MID-LEVEL TROF
AXIS BEGINS TO SWING THRU SHIFTING WINDS TO THE W. THIS WILL ALLOW
FOR COLD FRONT CURRENTLY IN THE TX PANHANDLE TO DROP S INTO THE PB
BY TMRW AFTERNOON. ETA IS INDICATING MUCH COOLER TEMPS WITH PASSAGE
OF THE MID-LEVEL TROF AND ASSOCD PAC COLD FRONT. TEMPS DIFFICULT DO
TO TIMING OF FROPA AND WILL GO SLIGHTLY BELOW FWC AND ABOVE ETA
AS SIGNIFICANT DOWNSLOPE WARMING OCCURS IN ADVANCE OF FRONT IN TX
PANHANDLE. COORD WITH LBB AND SPC.
