A WATCH DOES NOT APPEAR LIKELY UNLESS STORM-SCALE TRENDS     DICTATE OTHERWISE.          DISCUSSION...TSTMS HAVE INCREASED OVER THE PAST FEW HOURS IN     VICINITY OF A WEAK BOUNDARY AND OTHERWISE AN EASTERLY LOW-LEVEL     UPSLOPE REGIME ACROSS THE REGION. WITH VERY WEAK DEEP TROPOSPHERIC     FLOW IN PROXIMITY TO THE UPPER RIDGE...STORMS WILL LIKELY CONTINUE     TO PROPAGATE GENERALLY WESTWARD ACROSS THE REGION. PARTICULARLY     ORGANIZED/SUSTAINED INDIVIDUAL UPDRAFTS ARE NOT EXPECTED...BUT AMPLE     INSTABILITY AND A DEEPLY MIXED BOUNDARY LAYER MAY ALLOW FOR SOME     DOWNBURST AND PULSE-TYPE HAIL POTENTIAL INTO EARLY EVENING.          ..GUYER/CARBIN.. 06/04/2012               ATTN...WFO...LUB...AMA...MAF...ABQ...
