  Concerning...Severe Thunderstorm Watch 583...  
    
  Valid 142355Z - 150130Z  
    
  The severe weather threat for Severe Thunderstorm Watch 583  
  continues.  
    
  SUMMARY...Severe potential continues within WW583.  
    
  DISCUSSION...Thunderstorms continue south and eastward within WW583.  
  These have shown a gradual weakening trend but will continue to pose  
  some risk for strong to severe wind in the near term given the hot  
  and unstable environment downstream. Further weakening is expected  
  with loss of daytime heating and movement into a region with less  
  shear for organization occurs in the next hour. As such, downstream  
  watch issuance is not expected.
