CONCERNING...SEVERE THUNDERSTORM WATCH 776...777...

VALID 092359Z - 100130Z

SCATTERED STORMS ONGOING ACROSS ERN UT AND WRN CO MAY HAVE AN
ISOLATED SEVERE THREAT OVER THE NEXT FEW HOURS. HOWEVER...THE THREAT
IS EXPECTED TO BECOME MARGINAL LATER THIS EVENING.

AT UPPER-LEVELS...A SWRN TROUGH IS TAKING SHAPE ACROSS NV WITH AN
EJECTING WEAK SHORTWAVE TROUGH CURRENTLY MOVING NEWD THROUGH ERN NV
AND SRN UT. STRONG ASCENT IS SPREADING ACROSS ERN UT AND WRN CO
WHICH IS SUPPORTING SCATTERED THUNDERSTORM DEVELOPMENT. ALTHOUGH SFC
OBSERVATIONS SHOW DRYING CONDITIONS FROM THE SOUTHWEST...ENOUGH
INSTABILITY STILL EXISTS ALONG WITH STRONG DEEP LAYER SHEAR FOR AN
ISOLATED SEVERE THREAT. HAIL WOULD BE THE PRIMARY THREAT ALTHOUGH A
FEW STRONG WIND GUSTS WILL ALSO BE POSSIBLE. THE SEVERE THREAT
SHOULD BEGIN DIMINISHING WITHIN A FEW HOURS AS INSTABILITY DECREASES
ACROSS THE REGION.
