   Mesoscale Discussion 0346
   NWS Storm Prediction Center Norman OK
   0415 AM CDT Sun Apr 12 2020

   Areas affected...Central Texas

   Concerning...Tornado Watch 104...

   Valid 120915Z - 121045Z

   The severe weather threat for Tornado Watch 104 continues.

   SUMMARY...Thunderstorms spreading into and across the Interstate 35
   corridor will continue to pose a risk for severe hail and perhaps a
   tornado or two. Potential for damaging wind gusts may gradually
   increase to the east of I-35 by 6-8 AM CDT.

   DISCUSSION...Thunderstorm intensities within the frontogenetically
   forced band of convection have generally weakened, as activity
   advances east-northeast of the Texas South Plains and Permian Basin
   at around 40 kt.  Preceding this line, scattered intense
   thunderstorm activity,  within the lower/mid tropospheric warm
   advection regime remains largely discrete, including a few
   supercells, as it spreads toward the Interstate 35 corridor between
   the Dallas/Fort Worth Metroplex and San Antonio.  However, coverage
   is still increasing, and associated cold pools may begin to
   consolidate supporting further gradual upscale convective growth
   through 11-13Z.  Until then, severe hail will remain possible in
   strongest storms, with at least some continuing risk for tornadic
   development.
