   THE SEVERE WEATHER THREAT FOR TORNADO WATCH 360 CONTINUES.
   
   SUMMARY...WW 360 IS SCHEDULED TO EXPIRE AT 05Z. ALTHOUGH THE TORNADO
   THREAT APPEARS TO HAVE BECOME MINIMAL...A RISK FOR MARGINALLY SEVERE
   HAIL MAY PERSIST WITH POST-FRONTAL CONVECTION JUST E OF THE I-15
   CORRIDOR. NEW WW ISSUANCE IS NOT ANTICIPATED.
   
   DISCUSSION...SEVERE-PRODUCING SUPERCELLS THAT TRACKED ACROSS ERN
   PORTIONS OF WW 360 EARLIER THIS EVENING HAVE NOW CROSSED INTO
   ALBERTA. STILL...STRONG CONVECTION PERSISTS TO THE WEST OF THE
   COMPOSITE FRONT/OUTFLOW THAT EXTENDS FROM AROUND 20 W HVR TO 20 E
   LWT. 40-50 KT EFFECTIVE SHEAR WILL REMAIN SUFFICIENT FOR MARGINALLY
   SEVERE HAIL WITH THE MORE INTENSE CORES UNTIL CONVECTION ULTIMATELY
   PROGRESSES N INTO ALBERTA.
