   ...MO RIVER VALLEY...
   SERIES OF STRONG SHORTWAVE TROUGHS WILL TRACK EASTWARD ACROSS THE
   NORTHERN TIER OF STATES ON SATURDAY...WITH PERSISTENT SOUTHERN
   STREAM UPPER TROUGH REMAINING OVER NORTHERN MEXICO.  STRONG SURFACE
   COLD FRONT IS FORECAST TO SURGE SOUTHEASTWARD ACROSS THE
   NORTHERN/CENTRAL PLAINS DURING THE AFTERNOON/EVENING...WITH STRONG
   LARGE SCALE FORCING FOR PRECIPITATION AND SCATTERED CONVECTION. 
   PRESENT INDICATIONS ARE THAT VERY LIMITED LOW LEVEL MOISTURE WILL BE
   IN PLACE AHEAD OF FRONT...WITH MAIN THUNDERSTORM THREAT DURING THE
   EVENING OVER PARTS OF EASTERN KS/WESTERN MO.  WEAK INSTABILITY IS
   EXPECTED TO PRECLUDE ORGANIZED SEVERE STORMS IN THIS REGION.
   
   ...ERN NM/WEST TX...
   LOW LEVEL MOISTURE WILL SLOWLY RETURN TO CENTRAL/WEST TX ON
   SATURDAY...WITH DEWPOINTS RISING INTO THE 50S BENEATH A RATHER COOL
   MID LEVEL AIRMASS.  POCKETS OF STRONG DAYTIME HEATING AND STEEP
   LAPSE RATES MAY RESULT IN MUCAPE VALUES OF 500-1000 J/KG...AND A
   RISK OF HAIL IN ANY STORMS THAT DEVELOP.  THIS REGION WILL
   EXPERIENCE SHORTWAVE RIDGING MOST OF THE FORECAST PERIOD...WITH
   LITTLE FORCING EXPECTED FOR CONVECTIVE DEVELOPMENT. 
   HOWEVER...POTENTIAL EXISTS FOR ISOLATED STORMS TO MOVE OFF THE
   MOUNTAINS OF EASTERN NM INTO WEST TX.  THIS AREA WILL CONTINUE TO BE
   EVALUATED IN LATER OUTLOOKS.
