Watch issuance likely needed soon. DISCUSSION...As of 19z, an established line of thunderstorms was ongoing across portions of Alabama, with more discrete cells located ahead of and south of the line in southwestern Alabama and Mississippi. Across southeastern Alabama into the Florida Panhandle, air mass destabilization from daytime heating has led to surface based CAPE values around 1500 J/kg. KEOX (Ft. Rucker) has seen an increase in 0-1km and 0-3 km storm relative helicity in the last few hours as 850 mb flow has increased to around 40-50 kts. 0-1km storm relative helicity is currently around 230 m2/s2. This environment is expected to persist and will support the risk for tornadoes, especially within any discrete cells that can maintain supercell characteristics ahead of the main line. ...Thornton/Guyer.. 01/12/2023 ....Please see https://urldefense.com/v3/__http://www.spc.noaa.gov__;!!DZ3fj= g!980vD-2OzsxkXirROKQSNDOkiSQp2UyDjlCCvO9_lGU0hNzT63gSYwRIfTalXxYritrbe-jhO= D1PuSiiwX9j5bRYgDk$ for graphic product...
