   Mesoscale Discussion 0049
   NWS Storm Prediction Center Norman OK
   0202 AM CST Sun Jan 15 2017

   Areas affected...Eastern KS...I-70 corridor of MO

   Concerning...Freezing rain 

   Valid 150802Z - 151300Z

   SUMMARY...Some expansion in the coverage and intensity of freezing
   rain is possible overnight, with hourly rates of 0.03 - 0.05
   inches/hour possible.

   DISCUSSION...At 0745 UTC, a precipitation shield was slowly
   expanding northeastward into portions of east-central Kansas and the
   I-70 corridor of Missouri that remain below freezing. While the
   strongest warm advection is focused further to the west over
   central/western KS, ascent associated with a departing upper-level
   jet streak over the Great Lakes should help to maintain light
   precipitation across the MCD area through 12-13Z. Even with
   relatively modest ascent, PW values approaching 1 inch will support
   precipitation rates of around 0.03 - 0.05 inches per hour. 

   The 0-degree C temperature and wet bulb contours have moved very
   little over the past several hours, and only a very slow northward
   movement is expected before sunrise, given the lack of a stronger
   warm advection regime. Ice accretion may be somewhat less efficient
   over the southern portion of the MCD area, where temps are in the
   30-32F range, while wet-bulb cooling will support temperatures in
   the upper 20s and more efficient accretion across the northern
   portion of the area.
