   The severe weather threat for Severe Thunderstorm Watch 405
   continues.

   SUMMARY...A small, intense bowing complex will pose a threat for
   significant severe wind gusts of 75-100 mph this evening as it
   spreads eastward across southwestern Kansas and northwestern OK.

   DISCUSSION...Multiple measured severe wind gusts ranging from 65 mph
   up to around 100 mph and damage reports have recently occurred in
   the OK Panhandle with a small bowing cluster now moving into far
   northwestern OK and southwestern KS. Strong inbound velocities noted
   from KVNX around 9000 ft AGL along the apex of the bow suggest the
   development of a pronounced rear-inflow jet. The thermodynamic
   environment in the near term (next 1-2 hours) should remain quite
   favorable for significant severe wind gusts of 75-100 mph in a
   narrow corridor across far northwestern OK into southwestern and
   south-central KS. Instability gradually decreases with eastward
   extent into north-central OK and south-central KS along/north of a
   stalled surface boundary. The potential for significant severe winds
   farther east into these areas beyond 04Z (11 PM CDT) is less clear
   owing to the somewhat weaker instability. Still, some severe wind
   threat will likely persist tonight as the bowing complex develops
   eastward.
