The NWS Storm Prediction Center has issued a
* Severe Thunderstorm Watch for portions of
Southern and eastern Kansas

until 200 AM CDT.
* Primary threats include...
Scattered large hail likely with isolated very large hail events

A tornado or two possible
SUMMARY...Storms will continue to develop initially along a boundary
that extends from southwest Kansas northeastward into northeast
Kansas and northern Missouri. Very steep lapse rates, strong

potential for damaging winds may increase as storms tend to cluster
this evening and move east-southeastward across the region.
The severe thunderstorm watch area is approximately along and 65
statute miles north and south of a line from 50 miles south of
Kirksville MO to 30 miles southwest of Garden City KS. For a
