   Areas affected...Southern and central Arkansas

   Concerning...Severe Thunderstorm Watch 297...

   Valid 150119Z - 150245Z

   The severe weather threat for Severe Thunderstorm Watch 297
   continues.

   SUMMARY...A large to very large hail threat continues across
   Arkansas this evening.

   DISCUSSION...Supercells continue to develop across Arkansas this
   evening on the eastern edge of a steeper mid-level lapse rate plume.
   The environment remains very favorable with 3000+ J/kg MUCAPE and
   effective shear of 60 to 70 knots. Expect continued development well
   into the overnight period as the reservoir of buoyancy continues to
   be replenished from the west and as a shortwave across northeast
   Oklahoma (associated with showers east of Tulsa) approaches the
   area. This is supported by the 00Z HRRR which shows continued
   supercell development across Arkansas through 05-06Z.
