Mesoscale Discussion 1057 NWS Storm Prediction Center Norman OK 0710 PM CDT Wed Jun 14 2023 Areas affected...Southeast Arkansas...Mississippi...Northeast Louisiana 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. ..Darrow.. 06/15/2023 ...Please see www.spc.noaa.gov for graphic product...
