   Mesoscale Discussion 0022
   NWS Storm Prediction Center Norman OK
   0642 AM CST Thu Jan 09 2025

   Areas affected...West Texas into north central Texas and southern
   Oklahoma.

   Concerning...Winter mixed precipitation 

   Valid 091242Z - 091515Z

   SUMMARY...A mix of snow, freezing rain and occasional sleet is
   expanding from West Texas to the Red River.

   DISCUSSION...A precipitation shield has expanded across West Texas,
   the Texas Panhandle, and southern Oklahoma as isentropic ascent
   strengthens ahead of an approaching mid-level trough. Many
   observation sites across West Texas have observed freezing rain this
   morning with relatively light accumulation. However, as
   precipitation intensifies, isolated greater accumulation amounts
   have been observed (KABI reported 0.14 inches of ice accretion
   between 11Z and 12Z), with this likely continuing through the
   morning. While some mixed phase precipitation may occur this morning
   while the boundary layer is moistening across Oklahoma and North
   Texas, expect mostly snow across this region by mid-morning given
   the thermal profile from the KOUN 12Z RAOB. Farther south, expect
   freezing rain to persist this morning before temperatures should
   rise above freezing by late morning as low-level flow/warm air
   advection strengthens.
