   The severe weather threat for Severe Thunderstorm Watch 310
   continues.

   SUMMARY...Strong/severe storms continue over parts of eastern
   Colorado and adjacent/far western Kansas.  As risk expands/spreads
   eastward with time this evening, an eventual/new WW extending into
   central Kansas appears likely.

   DISCUSSION...Latest radar loop shows storms congealing into a fairly
   intense cluster over the Cheyenne/Kit Carson County vicinity in
   east-central Colorado, with some initial/subtle hints of possible
   mesolow development.  Farther southeast, a somewhat loosely
   organized band of storms is indicated, with an eventual merging of
   these two convective areas expected with time.

   As the eastern Colorado/western Kansas convection evolves, eastward
   advance of the storms will eventually result in severe risk
   spreading across eastern portions of WW 310, into central Kansas. 
   This would likely warrant eventual/new WW issuance, as a developing
   low-level jet supports convective continuation.  Meanwhile though, a
   small but rather vigorous cluster of updrafts has developed just
   west of Pratt, KS, east of the southeastern corner of WW 310.  We
   will continue to monitor evolution of this convective cluster, as
   any additional increase in convection could force earlier
   consideration for a new WW east of WW 310 than may otherwise have
   been necessary.
