   Areas affected...western Nebraska and northeast Colorado

   Concerning...Severe potential...Watch possible 

   Valid 090201Z - 090400Z

   Probability of Watch Issuance...40 percent

   SUMMARY...Storm coverage will likely increase in the next couple of
   hours across portions of western Nebraska and northeast Colorado.
   Large hail and damaging winds will be the main threats. A new watch
   issuance and/or watch extension are possible.

   DISCUSSION...Storms are developing across northeast Colorado and far
   western Nebraska behind a surface cold front. An upper-level trough
   is slowly moving across the Intermountain West with
   height/temperature falls occur across the central and northern High
   Plains. This increasing mid-level instability coupled with a
   strengthening low-level jet this evening/tonight will likely
   increase storm coverage across this area. Large hail is possible
   with these storms as the LBF 00z sounding indicates stronger
   vertical shear with relatively long hodographs. While the storms
   will be elevated, strong winds will likely penetrate the low-level
   inversion and reach the surface. Storms will likely continue into
   tonight across the area.
