   Areas affected...Parts of northeastern Minnesota

   Concerning...Severe Thunderstorm Watch 626...

   Valid 252133Z - 252230Z

   The severe weather threat for Severe Thunderstorm Watch 626
   continues.

   SUMMARY...A highly localized favorable corridor for supercell
   intensification and a brief tornado and damaging wind gusts may
   persist for another hour or so.

   DISCUSSION...A weak, semi-discrete supercell structure is tracking
   eastward across parts of northeastern MN, with access to
   warm/unstable inflow to its southeast. Trailing cells and associated
   outflow are approaching this storm from the west. This could support
   a constructive cell interaction and brief intensification of the
   supercell as it continues eastward for the next 30 min to an hour --
   before being undercut by the outflow. This could support a locally
   favorable risk for a brief tornado and damaging wind gusts.
