   Mesoscale Discussion 1402
   NWS Storm Prediction Center Norman OK
   0922 PM CDT Sat Jul 22 2017

   Areas affected...Northeast Kansas into west central Missouri

   Concerning...Severe Thunderstorm Watch 433...

   Valid 230222Z - 230415Z

   The severe weather threat for Severe Thunderstorm Watch 433
   continues.

   SUMMARY...Sporadic severe storms capable of damaging winds and
   localized large hail remain likely across the watch area.

   DISCUSSION...A large mass of thunderstorms continues to evolve
   slowly eastward out of Kansas, with multiple measured wind gusts
   over 50 kt earlier. Radar indicates substantial outflow being
   produced with these storms, which have been undercutting others and
   limiting propagation. Recently, cells over eastern Kansas (Douglas
   into Johnson counties) have shown signs of maintaining a reasonable
   eastward propagational speed, with outflow remaining near the
   storms. Other cells were rapidly developing ahead of it, with at
   least marginally severe hail or wind expected. Surging outflow from
   the west may also given an additional boost to the eastern storms.
   Given strong instability surrounding these storms, strong to severe
   outflow winds are possible radiating in all directions. Further
   development is expected with eastward extend this evening.
