   Mesoscale Discussion 0092
   NWS Storm Prediction Center Norman OK
   0235 AM CST Tue Jan 24 2023

   Areas affected...a small portion of east-central New Mexico and into
   an adjacent portion of the Texas South Plains

   Concerning...Heavy snow 

   Valid 240835Z - 241100Z

   SUMMARY...Snowfall rates in excess of 1" per hour are expected over
   the next couple of hours in few-county area surrounding Clovis New
   Mexico, straddling the New Mexico/Texas border.

   DISCUSSION...Latest water-vapor loop shows the primary upper center
   of circulation entering far southwestern New Mexico at this time,
   and moving very slowly eastward.  Meanwhile, a smaller/more subtle
   vort max is evident just southwest of the discussion area, moving
   slowly northeastward.  This is contributing to the area of maximized
   ascent/precipitation that extends from east-central New Mexico,
   across the Texas South Plains and southern parts of the Panhandle.

   While much of this precipitation east of the Caprock is falling as
   rain, due to surface temperatures in the upper 30s to low 40s, snow
   is observed westward across the Lubbock and Plainview areas and into
   the Clovis vicinity.

   A roughly east-to-west band of heavier precipitation is generally
   advancing northward toward the Texas Panhandle.  As such, heavier
   snowfall rates are generally occurring for only a limited amount of
   time over any one area.  However, the band has remained
   quasi-stationary within the discussion area over the past hour or so
   -- which seems to be due to some easterly/locally east-northeasterly
   upslope flow.  As the aforementioned vort max translates only slowly
   northeastward, this area of enhanced snowfall rates appears likely
   to continue across the discussion area over the next couple of
