   Concerning...Severe Thunderstorm Watch 652...

   Valid 170030Z - 170230Z

   The severe weather threat for Severe Thunderstorm Watch 652
   continues.

   SUMMARY...A threat for large hail and wind damage is expected to
   continue over the next few hours, from eastern Minnesota into
   northwest Wisconsin and far western Upper Michigan.

   DISCUSSION...The latest high-resolution radar imagery from Duluth
   shows a continuous line of strong to severe thunderstorms across
   northern Wisconsin and far eastern Minnesota. This line is located
   near a cold front, along an axis of moderate instability where the
   RAP is analyzing MLCAPE in the 1000 to 2000 J/kg range. This
   convection is being supported by large-scale ascent associated with
   an upper-level trough moving eastward into the upper Mississippi
   Valley. The latest WSR-88D VWP at Duluth has 0-6 km shear near 65
   knots with strong speed shear in the lowest 2 km above ground level.
   This wind profile will continue to support a severe threat as the
   line move eastward across northwestern Wisconsin this evening. The
   RAP also has 700-500 mb lapse rates near 7.5 C/km suggesting a
   threat for large hail will be possible with embedded cells that
   rotate. A wind-damage threat will also be possible along the leading
   edge of the more intense and faster moving parts of the line.
