DISCUSSION...In the wake of earlier convection this morning, some airmass recovery has occurred across parts of southeastern/coastal GA and north FL. Recent radar imagery shows an outflow boundary from prior thunderstorms is still continuing southward along/near the FL/GA line. But, filtered daytime heating to the north of this boundary has allowed surface temperatures to generally increase into the low to mid 80s downstream of multiple supercells ongoing across southwestern into south-central GA. There are still some concerns about instability due to a large area of remnant stratiform precipitation, with MLCAPE quickly dropping off with northward extent across coastal GA into southern SC. Regardless, deep-layer shear still appears strong enough (35-45+ kt) to support supercells. Current expectations are for the ongoing supercells to spread eastward over the next few hours, while posing a threat for large hail and damaging winds. Enough low-level shear is also present to foster low-level updraft rotation and some risk for a couple of tornadoes. Convective trends will be monitored for possible watch issuance this afternoon. ...Gleason/Thompson.. 06/14/2023 ....Please see https://urldefense.com/v3/__http://www.spc.noaa.gov__;!!DZ3fj= g!-gDyurmKFMBRSL1hd4-uPp_CDalSldYSvvvQh9_z-r0f6wvO14P7IPHOhFoixyRC1NfUwyRz4= eIZ-JoNYlBYqL_OF_U$ for graphic product...
