Additional thunderstorm development is possible this afternoon, with the primary threats being locally damaging wind gusts and hail. DISCUSSION...An area of ongoing and developing thunderstorms is currently moving through southeastern OK into the Arklatex region, with local MESH cores recently exceeding 1". The storms are generally propagating east-southeastward along a cold front, which is being convectively reinforced in central/southern OK by the system's cold pool. Convective redevelopment across southeastern OK -- and surface temperatures warming into the mid-/upper-80s -- are evidence of negligible remaining MLCIN as of 17z. MLCAPE around 2000-2500 J/kg currently resides in the Arklatex region, which is expected to increase gradually throughout the afternoon. Vertical wind shear is rather meager but should gradually strengthen during the next few hours, perhaps to around 15 kts of 0-6-km shear by 20z. In line with the destabilizing environment, numerical guidance depicts increasing convective coverage through peak diurnal heating. Increasing shear amidst steadily steepening lapse rates (to around 7.5 C/km in the lowest 3 km AGL) could foster sporadic damaging wind gusts and small hail with the strongest storms by mid-afternoon. Overall severe coverage appears rather limited, and watch issuance is not anticipated. ...Flournoy/Grams.. 07/06/2023 ....Please see https://urldefense.com/v3/__http://www.spc.noaa.gov__;!!DZ3fj= g!61BD-rTuTaVJvoIg2o68nX2Oy9gomHkajQpvpJVZrrxEA0lvTUYLgIePa8Z8WXkhQ5hpjoDE5= GbhekTiyqxB7Yo1Ry8$ for graphic product...
