   Areas affected...Central and Southwest Nebraska...Far Northeast
   Colorado

   Concerning...Severe Thunderstorm Watch 450...

   Valid 040237Z - 040430Z

   The severe weather threat for Severe Thunderstorm Watch 450
   continues.

   SUMMARY...A threat for severe wind gusts and isolated large hail
   will likely continue over the next few hours. As storms move
   eastward into southwest Nebraska, a watch extension in area may be
   needed.

   DISCUSSION...The latest radar imagery shows a couple of intense
   storms over the central High Plains. The first storm is in
   west-central Nebraska with the second in far northeast Colorado.
   These storms are located near a shortwave trough evident on water
   vapor imagery, which is providing large-scale ascent helping to
   sustain the storms. Ahead of the storms, a moderately unstable
   airmass is located across much of southern and central Nebraska,
   where the RAP has MLCAPE in the 2000 to 3500 J/kg range. In
   addition, the North Platte WSR-88D VWP has 0-6 km shear around 40
   knots. This will support supercell maintenance late this evening.
   Supercells should be capable of isolated large hail and severe wind
   gusts. As the storms in far northeast Colorado move eastward into
   southwest Nebraska later this evening, a watch extension in area may
   need to be considered.
