CONCERNING...SEVERE THUNDERSTORM WATCH 455...

VALID 092211Z - 100015Z

ORGANIZED CLUSTER OF TSTMS OVER THE UT/NV BORDER WILL MOVE EWD
AROUND 30 KTS INTO THE SLC METRO AREA BETWEEN 00-01Z. MORE STABLE
AIRMASS OVER THE SLC AREA/WASATCH FRONT WILL LIKELY LIMIT THE
SEVERITY OF THE WIND THREAT...BUT WE WILL CONTINUE TO MONITOR TRENDS
FOR THE POSSIBILITY OF AN ADDITIONAL WW.

CONVECTIVE LINE OVER NERN NV AHEAD OF UPPER VORT MAX WILL CONTINUE
TO MOVE EWD INTO NWRN/NRN UT OVER THE NEXT SEVERAL HRS. SFC AIRMASS
HAS BEEN STABILIZED BY EARLIER CONVECTIVE LINE OVER NRN UT. RECENT
SAT IMAGERY SHOWS CLEARING SKIES WHICH MAY AID TO SUPPORT SOME
ADDITIONAL DESTABILIZATION OVER THIS AREA AHEAD OF THE CONVECTIVE
LINE. ADDITIONAL TSTMS ARE LIKELY TO CONTINUE DEVELOPING AND
INTENSIFYING ALONG THE REMNANT OUTFLOW BOUNDARY FROM WHITE PINE
COUNTY NV EWD INTO JUAB AND MILLARD COUNTIES UT. MODERATE MID LEVEL
FLOW /30-40 KTS OF DEEP LAYER SHEAR/ ALONG WITH ADEQUATE INSTABILITY
/1000 J/KG OF MLCAPE/ WILL SUPPORT A SVR THREAT IN SRN/SERN PORTIONS
OF WW 455 FOR AT LEAST THE NEXT SEVERAL HRS WITH THESE STORMS.
