   ...MID MS VALLEY...
   
   EARLY MORNING WATER VAPOR IMAGERY CLEARLY DEPICTS LARGE SCALE
   FORCING ASSOCIATED WITH UPPER SPEED MAX OVER AR LIFTING NEWD TOWARD
   THE OH VALLEY.  DEEP WLY FLOW IN ADVANCE OF THIS FEATURE FORCED A
   PLUME OF STEEP MID LEVEL LAPSE RATES AS FAR AS THE MS VALLEY WHERE
   ISOLATED THUNDERSTORMS MANAGED TO DEVELOP WITHIN ZONE OF ELEVATED
   INSTABILITY OVER THE LAST FEW HOURS.  CONVECTIVE OVERTURNING
   HOWEVER HAS STABILIZED THIS REGION AND ACTIVITY APPEARS TO BE
   DECREASING IN BOTH LIGHTNING FREQUENCY AND INTENSITY. 
   THUNDERSTORMS MAY STRUGGLE TO DEVELOP ACROSS THIS REGION AS LARGE
   SCALE ASCENT SPREADS DOWNSTREAM.
   
   ...TX...
   
   FARTHER SOUTHWEST...TRAILING COLD FRONT SHOULD BE FORCED SWD INTO
   CENTRAL/ERN TX IN WAKE OF UPPER SHORTWAVE TROUGH.  WEAK CONVERGENCE
   AND DILUTED SUNSHINE ALONG THE BOUNDARY MAY PROVE INEFFECTIVE IN
   DRIVING DEEP CONVECTION THIS AFTERNOON...EXCEPT ACROSS FAR WEST TX
   WHERE ISOLATED THUNDERSTORMS MAY DEVELOP OVER HIGHER TERRAIN. 
   LATER TONIGHT...WARM ADVECTION WILL INCREASE NORTH OF THE BOUNDARY
   AND ELEVATED CONVECTION/ISOLATED THUNDERSTORMS ARE POSSIBLE.  WEAK
   INSTABILITY WILL PRECLUDE SEVERE ACTIVITY.
   
   ...PACIFIC COAST...
   
   SATELLITE IMAGERY INDICATES UPPER SPEED MAX IS INCREASING IN
   INTENSITY OFF THE NRN CA COAST WHICH IS ENHANCING STRONG SSEWD
   MOVEMENT OF UPPER TROUGH.  MID LEVEL CAA SHOULD AID IN POST FRONTAL
   DESTABILIZATION ACROSS MUCH OF NRN CA INTO SWRN ORE...ESPECIALLY IF
   PARTIAL SUNSHINE CAN DEVELOP BENEATH THE UPPER TROUGH.  ISOLATED
   LOW-TOPPED THUNDERSTORMS APPEAR A REASONABLE POSSIBILITY DURING THE
   MID DAY-EARLY EVENING HOURS.
