   SFC TEMPERATURES HAVE WARMED CONSIDERABLY ACROSS ERN NM INTO THE TX
   SOUTH PLAINS...MAINLY JUST WEST OF ERODED EARLY MORNING STRATUS
   DECK. AS A RESULT...MID-UPPER 80S TEMPERATURES HAVE ALL BUT REMOVED
   INHIBITION ALONG A NARROW AXIS NEAR THE DRY LINE.  THIS IS EVIDENT
   BY RECENT BOUNDARY LAYER CU DEVELOPMENT/EXPANSION.  ALTHOUGH DEEP
   LAYER SHEAR IS NOT PARTICULARLY STRONG...VERY STEEP LOW LEVEL LAPSE
   RATES...IN EXCESS OF 9 C/KM...AND MLCAPE VALUES ON THE ORDER OF 1500
   J/KG...SUGGEST ROBUST UPDRAFTS ARE POSSIBLE WITHIN THE NEXT FEW
   HOURS.  A FEW THUNDERSTORMS COULD CERTAINLY PRODUCE LARGE HAIL OR
   PERHAPS LOCALLY SEVERE WIND GUSTS...AS DID DEEP CONVECTION THE LAST
   FEW AFTERNOONS.  WILL UPDATE THE 20Z OUTLOOK TO REFLECT THIS
   LOCALIZED SEVERE THREAT.
