MD 0017 CONCERNING HEAVY SNOW FOR EASTERN KS TO WEST-CENTRAL IL
Mesoscale Discussion 0017 NWS Storm Prediction Center Norman OK 1134 PM CST Fri Jan 11 2019 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. ..Darrow.. 01/12/2019 ...Please see www.spc.noaa.gov for graphic product...
