A strong area of low pressure crossed Kansas on Monday February 20th.  This storm
system brought multiple rounds of rainfall to the area through the day.  By afternoon, a 
narrow band of unstable air developed across central Kansas.  This instability coupled 
with strong wind shear to produce a line of strong to severe thunderstorms that tracked 
from central Kansas into Missouri.  There were many reports of pea size hail with a 
few instances of hail up to the size of quarters.  Meanwhile, wind gusts of 45 to 60 mph 
accompanied the thunderstorms as they passed through.
