   ...THERE IS A SLGT RISK OF SVR TSTMS FOR PORTIONS OF ERN NM TROUGH W

   ...SRN HIGH PLAINS...
   
   EARLY THIS EVENING AN AXIS OF MARGINAL TO MODERATE INSTABILITY
   EXTENDS FROM SW TX NWD THROUGH ERN NM AND INTO CNTRL PARTS OF W TX
   WITH MLCAPE FROM 500 TO 1200 J/KG. SCATTERED STORMS THAT DEVELOPED
   OVER THE HIGHER TERRAIN OF NM IN UPSLOPE REGIME HAVE SPREAD EWD INTO
   THE HIGH PLAINS OF ERN NM AND W TX. THOUGH ACTIVITY IS EVOLVING INTO
   AN MCS...A FEW DISCRETE CELLS INCLUDING SUPERCELLS PERSIST.
   
   SLY LOW LEVEL JET WILL INCREASE TONIGHT THROUGH W TX AND INTO WRN OK
   IN ADVANCE OF SHORTWAVE NOW MOVING EWD THROUGH NM. SURFACE BASED
   CONVECTIVE INHIBITION WILL INCREASE AS THE BOUNDARY LAYER COOLS AND
   SHOULD LIMIT SWD EXTENT OF DEVELOPMENT. HOWEVER...UPPER DIVERGENCE
   DOWNSTREAM FROM SHORTWAVE TROUGH AND LIFT ASSOCIATED WITH WARM
   ADVECTION ACCOMPANYING STRENGTHENING LOW LEVEL JET WILL SUPPORT
   ACTIVITY CONTINUING THROUGH W TX AND EVENTUALLY INTO OK. STRONGEST
   STORMS WILL LIKELY CONTINUE ON SRN HALF OF MCS IN CLOSER PROXIMITY
   TO FEED OF HIGHER INSTABILITY. STORMS MAY BECOME ELEVATED LATER
   TONIGHT AS BOUNDARY LAYER DECOUPLES. HOWEVER...THREAT FOR ISOLATED
   LARGE HAIL AND DAMAGING WIND SHOULD PERSIST AT LEAST INTO THE LATE
   EVENING THROUGH W TX BEFORE ACTIVITY GRADUALLY WEAKENS DUE TO
   INCREASINGLY MARGINAL INSTABILITY.
   
   OTHER MORE ISOLATED STORMS HAVE DEVELOPED OVER SW TX NEAR SAN ANGELO
   IN ASSOCIATION WITH A WEAKER SRN STREAM SHORTWAVE TROUGH AS WELL AS
   OVER THE DAVIES MOUNTAINS. THIS ACTIVITY EXISTS AN ENVIRONMENT WITH
   WEAKER SHEAR AND WHERE FORCING FOR ASCENT IS EXPECTED TO REMAIN
   RELATIVELY WEAK. THOUGH AN ISOLATED SEVERE THREAT MAY CONTINUE
   THROUGH MID EVENING..STORMS ARE EXPECTED TO WEAKEN AS THE BOUNDARY
   LAYER COOLS AND CONVECTIVE INHIBITION INCREASES.
