   The severe weather threat for Severe Thunderstorm Watch 422
   continues.

   SUMMARY...Threat for strong wind gusts will continue across
   southeast SD and far northeast NE, and into far southwest MN and far
   northwest IA over the next hour or so.

   DISCUSSION...Organized convective line continues to move
   northeastward across southeast SD and adjacent far northeast NE.
   Recent storm motion was estimated at 45-47 kt, bringing the line to
   the SD/MN/IA border intersection a little after 07Z. Echo tops have
   remained fairly consistent over the past hour or so, with the
   strongest cores currently arcing from Hutchinson County SD to Boone
   County NE. Near-severe gusts of 49 kt and 41 kt were recently
   measured at KHON and KYKN, respectively. 

   Low-level stability exists downstream, but the organized character
   of the convective line (evidenced by the well-defined rear-inflow
   jet on radar imagery) and steep mid-level lapse suggest the line
   should maintain its intensity for at least the next hour or so. As a
   result, the severe wind threat is expected to persist into far
   southwest MN and far northwest IA.
