   VALID 070259Z - 070400Z
   
   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 434
   CONTINUES.
   
   SEVERE TSTM WATCH 434 CONTINUES MAINLY FOR PORTIONS OF WEST-CENTRAL
   MT...ALTHOUGH THE SEVERE THREAT IS EXPECTED TO CONTINUE TO WANE THIS
   EVENING.
   
   THE STRONGEST STORMS THE REMAINDER OF THE EVENING WILL LIKELY BE
   CONFINED TO CENTRAL MT MAINLY EAST OF THE GREAT FALLS AREA...AS THE
   BOUNDARY LAYER ACROSS WEST-CENTRAL MT OTHERWISE CONTINUES TO
   STABILIZE POST-SUNSET AMID CONSIDERABLE CLOUD COVER. MODIFICATIONS
   TO THE 00Z GREAT FALLS OBSERVED RAOB SUPPORT THE NOTION OF
   INCREASING CINH/WANING NEAR-SURFACE BUOYANCY. THUS...THE POTENTIAL
   FOR SEVERE HAIL/WIND SHOULD CONTINUE TO DIMINISH ACROSS SEVERE TSTM
   WATCH 434.
