   CORRECTED FOR WRONG WATCH NUMBER

   The severe weather threat for Severe Thunderstorm Watch 377
   continues.

   SUMMARY...Severe threat will gradually shift southeast across
   ww0377.

   DISCUSSION...Low-amplitude, positive-tilt short-wave trough is
   currently ejecting northeast across southern MB/ND. Trailing
   influence of this feature appears to be aiding strong/severe
   convection that is approaching the Red River region, while a
   secondary short wave is likely aiding upstream activity that arcs
   across the western Dakotas. With time, surface front is expected to
   advance southeast across ww377, and this boundary will serve as the
   focus for ongoing/renewed development. Latest radar data suggests
   hail is approaching severe levels in many of the most robust
   updrafts. This trend should continue along with the threat for gusty
   winds.
