   Mesoscale Discussion 0300
   NWS Storm Prediction Center Norman OK
   1008 PM CDT Wed Apr 10 2019

   Areas affected...north-central Kansas into southeast Nebraska and
   southwest Iowa

   Concerning...Severe Thunderstorm Watch 47...

   Valid 110308Z - 110515Z

   The severe weather threat for Severe Thunderstorm Watch 47
   continues.

   SUMMARY...A hail threat will likely persist through the evening from
   northern Kansas into southeast Nebraska and southwest Iowa.

   DISCUSSION...Significant large-scale lift persists across the region
   with a deep low moving into northeast KS. While boundary layer
   moisture has been marginal for severe weather, the presence of steep
   lapse rates and favorable lift has led to scattered severe storms
   producing hail up to Golf-Ball size. Extremely strong shear profiles
   exist across the warm sector and north of the stationary/warm front,
   but much of this SRH has been rendered in-effective.

   Continued warm advection around the cyclone will support elevated
   hail through the evening. The prospect for surface based storms
   appears low at this time.
