   Areas affected...Northeast/East-Central CO...Northwest KS

   Concerning...Severe Thunderstorm Watch 419...

   Valid 060012Z - 060145Z

   The severe weather threat for Severe Thunderstorm Watch 419
   continues.

   SUMMARY...Convective trends are being monitored for possible watch
   issuance across northwest KS.

   DISCUSSION...Recent radar imagery shows an increased in
   thunderstorms Yuma County CO, ahead of the approaching convective
   line moving through Washington County CO. This convective line
   recently produced a 55 kt gust at AKO, and will begin interacting
   with the storms out ahead of it soon. As it does, there is some
   potential for the linear system to accelerate, resulting in an
   increased potential for strong wind gusts across Yuma County CO and
   potential into northwest KS. However, the low-level air mass will
   become increasingly stable over the next few hours, leading to
   uncertainty regarding the eastern extent of the severe threat. In
   contrast, steep mid-level lapse rates and a strengthening low-level
   jet could allow the line to persist across much of northwest KS.
   Convective trends are being monitored closely and there is some
   potential a small downstream watch may be needed across northwest
   KS.
