   CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY 
   
   VALID 220721Z - 220845Z
   
   A WW IS NOT CURRENTLY ANTICIPATED...BUT TRENDS WILL CONTINUE TO BE
   MONITORED FOR THE POSSIBILITY OF AN INCREASING SEVERE THREAT.
   
   RECENT INTENSIFICATION OF CONVECTIVE ACTIVITY ACROSS THE SOUTH
   CENTRAL HIGH PLAINS INTO THE CENTRAL PLAINS APPEARS TO LARGELY
   CORRESPOND WITH NOCTURNAL SOUTHERLY LOW-LEVEL JET INTENSIFICATION
   /45-50 KT AT 850 MB/ ACROSS THE HIGH PLAINS.  THIS FEATURE IS LIKELY
   REACHING ITS PEAK INTENSITY NOW...WITH A GRADUAL WEAKENING
   ANTICIPATED THROUGH THE 09-12Z TIME FRAME.  UNTIL THIS OCCURS...
   ONGOING STORMS MAY MAINTAIN THEIR CURRENT VIGOR.
   
   INCREASING STORM COVERAGE APPEARS LIKELY WITHIN DEVELOPING EAST-WEST
   BAND OF WARM ADVECTION EXTENDING ACROSS EASTERN COLORADO THROUGH
   SOUTHERN KANSAS...WHERE INSTABILITY MAY BE SUPPORTIVE OF OCCASIONAL
   MOSTLY MARGINALLY SEVERE HAIL.
   
   MEANWHILE...STRONG GUSTY WINDS APPEAR THE PRIMARY HAZARD WITH
   ONGOING STORM CLUSTER WEST/NORTHWEST OF LUBBOCK AND PLAINVIEW. 
   SUB-CLOUD TEMPERATURE/DEW POINT SPREADS...ABOVE SHALLOW COOL/MOIST
   SURFACE LAYER...APPEAR LARGE ENOUGH TO ENHANCE EVAPORATIVE COOLING
   AND DOWNWARD TRANSPORT OF MOMENTUM ASSOCIATED WITH THE LOW-LEVEL
   JET...AT LEAST THROUGH THE NORTHERN/EASTERN PANHANDLE
   REGION...BEFORE ACTIVITY WEAKENS TOWARD DAYBREAK.
