THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 614
CONTINUES.

A LOCALIZED SEVERE THREAT IS EXPECT TO PERSIST JUST E/S OF VALID
PORTIONS OF WW 614 THROUGH 05Z. LITTLE ADDITIONAL TSTM REDEVELOPMENT
IS EXPECTED ACROSS THE REMAINDER OF WW 614.

AS OF 0310Z...TWO MAIN CLUSTERS OF CONVECTION CONTINUE GENERALLY
NORTH OF I-80 IN NRN UT AND FARTHER NE INVOF RIW. THE MOST INTENSE
CELL HAS REACHED THE WASATCH RANGE AFTER PRODUCING A 59 KT GUST AT
HILL AFB IN OGDEN AROUND 02Z. LATEST VAD PROFILER FROM SALT LAKE
CITY UT INDICATES MORE THAN SUFFICIENT DEEP-LAYER SHEAR FOR
ORGANIZED UPDRAFTS /EFFECTIVE VALUES AROUND 40 KTS PER LATEST
OBJECTIVE ANALYSIS/. THIS MAY YET SUPPORT MARGINALLY SEVERE HAIL AND
PERHAPS A SEVERE WIND GUST OR TWO DESPITE NOCTURNAL BOUNDARY LAYER
COOLING AND INCREASINGLY ELEVATED NATURE OF TSTMS.
