   AREAS AFFECTED...EASTERN UT/WESTERN WY/SOUTHERN WY
   
   CONCERNING...SEVERE THUNDERSTORM WATCH 696...
   
   VALID 080001Z - 080100Z
   
   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 696
   CONTINUES.
   
   SEVERE THUNDERSTORM WATCH 696 CONTINUES UNTIL 02Z...WITH CONTINUED
   POTENTIAL FOR ISOLATED BOUTS OF SEVERE HAIL/WINDS GUSTS. OVERALL
   SEVERE POTENTIAL SHOULD BEGIN TO DIMINISH OVER THE NEXT FEW
   HOURS...AND CURRENT THINKING IS THAT WW 696 WILL BE ALLOWED TO
   EXPIRE AT/BY 02Z.
   
   ON THE SOUTHEAST PERIPHERY OF A CLOSED LOW OVER THE GREAT
   BASIN...WATER VAPOR IMAGERY REFLECTS A NORTH-NORTHEASTWARD PIVOTING
   SHORTWAVE TROUGH/SPEED MAX ACROSS CENTRAL UT EARLY THIS EVENING. THE
   COMBINATION OF COOL THERMAL PROFILES ALOFT AND VERY STRONG DEEP
   SOUTHERLY FLOW /REFERENCE GRAND JUNCTION WSR-88D VWP/ WILL CONTINUE
   TO SUPPORT SOME WELL-SUSTAINED/ORGANIZED STORMS CAPABLE OF SEVERE
   HAIL/WIND...MAINLY ACROSS NORTHEAST UT/FAR SOUTHWEST WY AND WESTERN
   CO OVER THE NEXT HOUR OR TWO. OTHERWISE...THE BOUNDARY LAYER WILL
   BEGIN TO GRADUALLY COOL...SUCH THAT THE SEVERE THREAT SHOULD BECOME
   MORE ISOLATED/MARGINAL THROUGH THE 01Z-02Z TIME FRAME.
