   Areas affected...northwest OK into portions of southwest KS

   Concerning...Heavy snow 

   Valid 281314Z - 281815Z

   SUMMARY...Areas of moderate to heavy snow are possible through this
   morning from northwest OK into parts of southwest KS.

   DISCUSSION...Areas of moderate to heavy snow continue to develop
   across southwest KS and northwest OK this morning. This activity is
   mainly being driven by strong 850mb warm advection ahead of the
   upper shortwave trough centered over the TX Panhandle vicinity as of
   13z. A shallow layer of low level cold advection is wrapping around
   the back side of a surface low located near CDS, and temperatures
   continue to fall across northwest OK. The depth of the dendritic
   growth zone will remain somewhat shallow, but strong forcing through
   the layer and deep, saturated vertical profiles should be sufficient
   for localized heavy snow bands to develop as the deformation zone
   pivots eastward across the area this morning. In addition to snow,
   northerly surface winds around 10-20 mph will result in blowing and
   drifting snow and further reduce visibility.
