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. ...Bentley.. 06/15/2023 ....Please see https://urldefense.com/v3/__http://www.spc.noaa.gov__;!!DZ3fj= g!9PzMHDuRvZqC2Hr4Mqm87DvFTB3uqR5TGkExpf3kVMUE9MM7UKU1u94k-TONqvoq93SlbtnvJ= oMr8ziN3EOpx437vBg$ for graphic product...
