   The severe weather threat for Severe Thunderstorm Watch 375

   SUMMARY...A severe threat is likely to continue for several more
   hours from far northeast Colorado into western and central Nebraska.
   Large hail and severe wind gusts will be the primary threats.

   DISCUSSION...The latest hi-resolution radar imagery from North
   Platte shows a cluster of strong to severe thunderstorms in far
   northeast Colorado and western Nebraska, where at least two
   supercells are ongoing. The storms are located along the western
   edge of a moist airmass. Surface dewpoints within this airmass are
   in the lower 60s F and the RAP is analyzing MLCAPE in the 2000 to
   3000 J/kg range. As the storms move eastward into more instability
   over the next few hours, the overall intensity of the cluster is
   expected to be maintained. The 20Z special sounding at North Platte,
   NE and RAP forecast soundings into early evening in same area have
   0-6 km shear of 40 to 45 knots with 700-500 mb lapse rates around
   8.5 C/km. This will support supercell development, with a potential
   for isolated large hail and severe wind gusts. The threat for severe
   gusts may increase if a cold pool can organize across western and
   central Nebraska.
