   Mesoscale Discussion 0013
   NWS Storm Prediction Center Norman OK
   1254 PM CST Fri Jan 10 2020

   Areas affected...Portions of central/eastern KS into far
   southeastern NE...northwestern MO...and southern IA

   Concerning...Freezing rain 

   Valid 101854Z - 110100Z

   SUMMARY...A mix of freezing rain, sleet, and snow will likely occur
   through the remainder of this afternoon and into the early evening.
   Freezing rain rates in excess of 0.05 inch per three hours should
   occur.

   DISCUSSION...18Z surface analysis shows a shallow arctic cold front
   advancing south-southeastward across the central Plains. A rapid
   transition from isolated hail potential to freezing rain concerns
   exists in a narrow corridor along and behind the front across parts
   of central/eastern KS into southern IA this afternoon. An area of
   ongoing precipitation associated with low-level warm advection
   occurring above the surface cold front should continue shifting
   northeastward over the next several hours. A pronounced warm nose in
   roughly the 900-750 mb layer noted on the 12Z sounding from TOP will
   be slow to erode, and complete melting aloft of frozen hydrometeors
   should occur initially. Refreezing at the surface will occur behind
   the cold front as temperatures rapidly fall into the mid to upper
   20s. A few surface observations already show this process occurring,
   with light to moderate freezing rain noted from central KS into
   northeastern KS, far southeastern NE, and southern IA. Potential
   exists for freezing rain rates to exceed 0.05 inch per 3 hours in a
   narrow southwest to northeast corridor across this region through
   the early evening, with some convective enhancement possible. A
   gradual transition to sleet and eventually snow appears likely as
   the warm nose aloft slowly erodes.
