   Areas affected...Portions of the Texas Panhandle into northwest
   Oklahoma

   Concerning...Heavy snow 

   Valid 091827Z - 092230Z

   SUMMARY...A nearly stationary band of heavy snow with rates around
   0.5-1 inch per hour (locally 1.5 inch) should persist across
   portions of the TX Panhandle into northwest OK for much of the
   afternoon.

   DISCUSSION...The latest radar data from KAMA depicts an increasingly
   organized band of moderate to locally heavy snow extending from the
   TX Panhandle into northwest OK. This organized band is likely being
   aided by a strengthening low/mid-level frontogenetic circulation
   ahead of the primary large-scale trough. Given the slow motion of
   the trough, and an embedded impulse tracking east-northeastward
   across the TX South Plains (evident in WV imagery), this band should
   remain persistent and nearly stationary through much of the
   afternoon. Steep midlevel lapse rates (sampled by earlier observed
   soundings) are likely supporting a convective enhancement to
   snowfall rates, and recent visible satellite imagery corroborates
   this as well. As a result, 0.5-1 inch per hour rates (locally 1.5
   inch) should persist under the core of the snow band before it
   becomes less organized.
