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.
