   The severe weather threat for Severe Thunderstorm Watch 355
   continues.

   SUMMARY...Upscale growth is expected with time. Storms will
   generally move into greater surface moisture to the southeast. The
   primary hazard will likely be severe wind gusts along with continued
   potential for large hail with discrete elements.

   DISCUSSION...Moist upslope flow into the central High Plains has
   promote semi-discrete storms near the Laramie Mountains. With
   downshear MLCIN remaining, storms have so far struggled to move
   eastward. Over the past 30 minutes, activity has begun to congeal.
   As a stronger cold pool develops, the expectation is for a cluster
   of storms to move southeastward into greater buoyancy and weaker
   MLCIN along the frontal zone of ascent. With the 21Z observed LBF
   sounding showing very steep mid-level lapse rates and objective
   analysis showing 40-50 kts of effective shear, large hail (isolated
   stones to around 2 in.) will be possible, particularly for the more
   discrete elements. Severe wind gusts may be the primary threat,
   however as a more linear storm mode should be favored with time.
