   Concerning...Severe Thunderstorm Watch 293...

   Valid 150010Z - 150115Z

   The severe weather threat for Severe Thunderstorm Watch 293
   continues.

   SUMMARY...New Severe Thunderstorm Watch will be issued by 01z to
   account for ww293 expiring.

   DISCUSSION...Water-vapor imagery depicts a mid-level short-wave
   trough over southern MO early this evening. Seasonally strong
   westerly 500mb flow currently extends across the southern Plains
   into the Gulf States with 50-60kt common. Isolated supercells
   persist immediately ahead of this feature over eastern AR. This
   activity should propagate southeast along the western fringe of
   convectively overturned air into central MS later this evening.
   Given the strong westerly shear, and buoyancy available, new severe
   thunderstorm watch is warranted by 01z.
