   Mesoscale Discussion 0123
   NWS Storm Prediction Center Norman OK
   1251 PM CST Thu Feb 18 2021

   Areas affected...southern Val Verde ...Kinney...and Uvalde counties
   in Texas

   Concerning...Heavy snow 

   Valid 181851Z - 182145Z

   SUMMARY...A narrow band of heavy snow continues across southern Val
   Verde, Kinney, and Uvalde counties in Texas. This band will
   gradually weaken through the afternoon.

   DISCUSSION...A band of heavy snow has become narrower, but heavy
   snowfall rates remain within this corridor from Del Rio, Texas
   eastward. Snowfall rates as high as 3 inches per hour have been
   reported in Del Rio this morning. Frontogenesis has started to
   weaken across the area, which is likely responsible for the
   narrowing corridor of the heaviest snow rates. As frontogenesis
   continues to weaken, snowfall rates will continue to lower, but 1+
   inch per hour snowfall rates could persist through mid to late
   afternoon beneath the heaviest portions of the band. The heaviest
   snowfall rates will likely remain near Del Rio where significant
   snowfall totals have already been reported.
