   The severe weather threat for Severe Thunderstorm Watch 479
   continues.

   SUMMARY...The risk for strong, potentially damaging wind gusts
   appears to be in the process of waning and this probably will
   continue as convection spreads east of WW 479.  A new severe weather
   watch is not anticipated, but trends will continue to be monitored.

   DISCUSSION...The conglomerate surface cold pool has maintained a
   general eastward propagation in excess of 40 kt, accompanied by
   occasional strong surface gusts.  However, trends in MRMS CAPPI,
   among other data, suggest that peak intensities within the more
   intense leading line are diminishing, as increasingly elevated
   updraft inflow becomes less unstable.  These trends are expected to
   continue as convection spreads into the upper Mississippi Valley
   through daybreak.
