   Areas affected...Southwest and Central Missouri...Far Northwest
   Arkansas

   Concerning...Heavy snow 

   Valid 151131Z - 151730Z

   SUMMARY...Areas of heavy snow are expected to develop this morning
   from central and southwestern Missouri into far northwestern
   Arkansas. Snowfall rates exceeding 1 inch per hour will be possible.

   DISCUSSION...The latest water-vapor imagery shows an upper-level low
   over central Kansas. This feature will continue to move southward
   into the southern Plains this morning. At the surface, a 1007 mb low
   is present in far southwestern Arkansas with an inverted trough
   extending northward into western Missouri, where a cold front is
   located. Large-scale ascent is maximized to the east of the low
   across parts of the Ozarks, where a large area of precipitation is
   ongoing. The precipitation consists of snow from central and western
   Missouri into far northwestern Arkansas. Rainfall is located across
   much of south-central and southeastern Missouri. Rain may change
   over to snow in some locations in south-central Missouri as
   temperatures cool above the boundary layer. The temperature could
   cool to 32 degrees F where the heaviest snowfall develops. Due to
   strong ascent associated with the upper-level low, heavy snow
   exceeding one inch per hour will be possible within the most
   organized snow banding.
