MD 1049 CONCERNING SEVERE POTENTIAL…WATCH LIKELY FOR SOUTHEASTERN OKLAHOMA AND CENTRAL ARKANSAS
Mesoscale Discussion 1049
NWS Storm Prediction Center Norman OK
0414 PM CDT Wed Jun 14 2023
Areas affected...Southeastern Oklahoma and central Arkansas
Concerning...Severe potential...Watch likely
Valid 142114Z - 142215Z
Probability of Watch Issuance...80 percent
SUMMARY...The risk for large hail and damaging winds may increase
this afternoon and evening. Supercells with large to very large hail
and damaging winds are the main risk. A new Weather Watch may be
needed.
DISCUSSION...In the wake of early day convection, new development
has been noted in the recovering air mass across far eastern OK and
central AR. Strong heating and unseasonably steep mid-level lapse
rates of 8-9 C/km were supporting 2500-300 J/kg of MLCAPE with 60-70
kt of effective shear from SPC mesoanalysis. As storms evolve and
mature, the cape/shear space, supercell mode, and very steep lapse
rates will favor large hail production with the more intense storms.
Significant hail (2+ in) also appears possible. Storms should
persist into this evening with a continued severe risk across
central and possibly eastern AR. A new Weather Watch is likely
needed this afternoon and evening.
