   WELL DEFINED SHORTWAVE TROUGH /NOW OVER WRN NM/ WILL SHIFT EWD
   ACROSS TX TONIGHT AND ENHANCE LARGE SCALE ASCENT ALONG NOSE OF
   ASSOCIATED SLY LLJ WHICH WILL INCREASE THIS EVENING AND GRADUALLY
   VEER OVERNIGHT.  MODELS CONSISTENT IN DEVELOPING SCATTERED TO
   WIDESPREAD THUNDERSTORMS LATER TODAY AHEAD OF THIS SYSTEM WHICH

   STORMS WILL DEVELOP AFTER 00Z AND REMAIN ROOTED NEAR H85.  STEEP
   LAPSE RATES AND STRONG CLOUD-LAYER SHEAR WILL SUPPORT A THREAT OF

   ...CENTRAL ROCKIES INTO THE NM HIGH PLAINS...
   COOL MID LEVEL TEMPERATURES AND INCREASED VERTICAL MOTION AHEAD OF

   MARGINAL INSTABILITY ACROSS SOME OF THE HIGHER TERRAIN OF CO/NM. 
   THUS...A FEW THUNDERSTORMS MAY DEVELOP OVER AND NEAR THESE AREAS. 
   ACTIVITY MAY BE MORE LIMITED OVER THE ERN NM PLAINS DUE TO VERY DRY
   LOW LEVEL AIR...THOUGH AN ISOLATED STORM MAY FORM LATE IN THE DAY AS
   MID LEVEL MOISTURE/LIFT AND WEAK INSTABILITY BECOME COLLOCATE.
