   Concerning...Severe Thunderstorm Watch 265...

   Valid 070434Z - 070600Z

   The severe weather threat for Severe Thunderstorm Watch 265
   continues.

   SUMMARY...Wind threat continues ahead of long-lived Derecho over the
   central Dakotas.

   DISCUSSION...Numerous measured severe wind gusts that were occurring
   with the long-lived Derecho have gradually lessened, with only
   isolated severe now being observed along the leading squall line.
   While this MCS appears to have weakened some over the last hour,
   likely due to encountering more stable boundary layer, forward
   propagation remains at least 50kt. Some damaging wind threat will
   continue with this activity despite convection likely becoming
   increasingly elevated in nature.
