   Areas affected...southeast Kansas...much of southern Missouri...far
   southern Illinois and western Kentucky

   Concerning...Winter mixed precipitation 

   Valid 051356Z - 051800Z

   SUMMARY...A combination of snow, sleet, and freezing rain will
   become mostly rain by late morning.

   DISCUSSION...13Z surface analysis shows a 1004 mb surface low in
   eastern Oklahoma with strong high pressure across the northern
   Plains and Great Lakes region. Northeasterly surface winds resulting
   from this pressure gradient continue to supply low-level arctic air
   to areas north of the warm front from Kansas to the Lower Ohio
   Valley. Strong 850mb warm air advection has resulted in a thermal
   profile favorable for freezing rain across a broad region from
   southeast Kansas and across much of southern Missouri early this
   morning. The 0C 850mb line will continue to slowly shift north as
   strong warm air advection occurs ahead of the surface cyclone. This
   will result in snow changing to freezing rain in the next few hours
   across parts of southern Illinois and western Kentucky. Areas across
   southern Missouri where temperatures are currently near freezing
   will likely rise above freezing this morning and bring an end to the
   freezing rain threat. However, for much of the area currently
   observing freezing rain, the threat will persist through at least
   midday.
