Areas affected...Eastern KS to West-Central IL

Concerning...Heavy snow 

Valid 120534Z - 120930Z

SUMMARY...Heavy snow will focus along a corridor from eastern KS,
across central MO, into west-central IL. Snow rates will be on the
order of 1"+ per hour.

DISCUSSION...Well-defined mid-level circulation has evolved over the
central Plains along the KS/OK border near Medicine Lodge (KP28).
Large-scale forcing for ascent appears to be increasing ahead of
this feature and precipitation is responding accordingly. Over the
last few hours the corresponding baroclinic leaf is sharpening which
supports radar trends of an expanding/intensifying shield of heavy
snow across portions of eastern KS into central MO. It appears a
corridor of heavy snow (1"+/hr) will establish itself over the next
few hours from near EMP in KS, downstream just south of the KC
metro, into west-central IL just north of the St. Louis area. Heavy
snow will likely continue along this corridor into the post-dawn
hours.
