   Areas affected...northeast Kansas...northwest Missouri...southern
   Iowa

   Concerning...Severe Thunderstorm Watch 172...173...

   Valid 120232Z - 120430Z

   The severe weather threat for Severe Thunderstorm Watch 172, 173
   continues.

   SUMMARY...A threat of damaging wind and hail continues across the
   watch area, and may extend into the remainder of southeast Kansas
   and western Missouri this evening.

   DISCUSSION...An MCS stretches from northeast KS into south central
   IA as of 0230Z. Northern portions of the line previously contained
   measured severe winds, but, may begin to weaken a bit as the most
   unstable air remains to the southwest. The bulk of the MCS was
   beginning to propagate in a more southerly direction, with locally
   damaging outflow winds along with embedded hail cores. A very
   unstable air mass extends from OK across eastern KS, and this air
   mass should maintain the MCS as it travels across the severe
   thunderstorm watch. Another watch may be needed later this evening
   for portions of southeast KS and western MO, should the storms still
   be severe at that time. 

   Farther north into central IA, the threat appears more marginal for
   both wind and hail, with a gradual weakening trend expected as these
   storms encounter a stabilizing air mass due to cool east winds.
