   The severe weather threat for Severe Thunderstorm Watch 380

   SUMMARY...The overall thunderstorm intensity continues to wane.
   However, gusty thunderstorm winds capable of sporadic tree damage
   may continue for another couple of hours.

   DISCUSSION...Thunderstorm intensity continues to decrease across
   northern Illinois as the nocturnal boundary layer deepens and,
   consequently, low-level buoyancy weakens. Although gusty
   thunderstorm winds on the leading edge of the convective line may
   yield sporadic tree damage, the potential for a more organized wind
   threat is diminishing.
