   Concerning...Severe Thunderstorm Watch 460...461...

   Valid 260708Z - 260845Z

   The severe weather threat for Severe Thunderstorm Watch 460, 461
   continues.

   SUMMARY...Threat for damaging gusts will continue across far
   southeast Nebraska and northeast Kansas for the next few hours.

   DISCUSSION...Convective line moving across southeast NE has shown a
   notable increase in forward progression over the last hour, with
   storm motion now estimated at 50 to 55 kt. Ample buoyancy exists
   downstream for maintenance of this line, with recent mesoanalysis
   estimating MUCAPE over 3000 J/kg. This line is also oriented nearly
   perpendicular to the deep-layer vertical shear vector, suggesting
   the recent increase in forward motion may persist as the line
   continues southeastward into northeast KS. These factors suggest the
   threat for damaging gusts will continue with the line for at least
   the next few hours. BIE recently gusted to 57 kt. 

   Over time, this convective line will likely interact with the
   slower-moving, more southward-progressing convective line (and
   associated outflow) that is moving from the MO River vicinity across
   northwest into central MO. How this interaction influences the
   either line is uncertain, but there is some chance for initial
   intensification of both lines before one becomes more dominant.
