MD 1058 CONCERNING SEVERE THUNDERSTORM WATCH 297… FOR SOUTHERN AND CENTRAL ARKANSAS
Mesoscale Discussion 1058
NWS Storm Prediction Center Norman OK
0819 PM CDT Wed Jun 14 2023
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.
