Valid 141804Z - 141930Z The severe weather threat for Tornado Watch 291, 292 continues. SUMMARY...The threat for tornadoes, some of which could be strong, large to very large hail, and severe/damaging winds will continue to increase this afternoon across parts of central Alabama into west-central/southwestern GA. DISCUSSION...Multiple supercells are present over parts of far southeastern AL into southwestern GA at 18Z. Some of these supercells have exhibited low-level rotation, with multiple debris signatures noted earlier. The environment across this area remains quite favorable for supercells, with 50+ kt of deep-layer shear estimated on recent VWPs from KEOX and other area radars. A convectively reinforced front is also draped northwest to southeast across this region, with supercells moving eastward across the boundary into west-central/southwestern GA. Even with low-level flow veered somewhat to west-southwesterly, backed near-surface winds in the vicinity of the front are supporting around 100-200 m2/s2 of effective SRH. Tornadoes will remain possible with any supercell that is sustained, along with large to very large hail. Across north-central AL, multiple clusters are spreading east-southeastward along and just north of the surface front. This convection may pose more of a severe/damaging wind threat in the short term. Another supercell has also recently strengthened across far east-central MS. Any supercells (like this one) that can persist across central AL will also pose a threat for very large hail (2-3+ inches in diameter) and tornadoes. ...Gleason.. 06/14/2023 ....Please see https://urldefense.com/v3/__http://www.spc.noaa.gov__;!!DZ3fj= g!8RzbvrMFv2ipeEjJKJf5XJV0FIBNGrCg8LfHLW15Ca-8Wah7hs7n2Y4itaFVRk_bow1f0qd9e= M1ejYwuhezHKWtRZdI$ for graphic product...
