MD 0300 CONCERNING SEVERE THUNDERSTORM WATCH 47… FOR NORTH-CENTRAL KANSAS INTO SOUTHEAST NEBRASKA AND SOUTHWEST IOWA

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.
