A watch issuance is likely before 0230Z. DISCUSSION...A QLCS is tracking eastward across western TN into northern MS, while northeastward-moving supercells are ongoing over northern into central MS. As a large-scale trough evident in water vapor imagery continues eastward this evening, the warm sector (characterized by middle/upper 60s dewpoints) will spread eastward into parts of western AL and Middle TN. At the same time, a strengthening low-level jet will also shift eastward over the warm sector, favoring a continuation of the severe storms with eastward extent. Large/clockwise-turning hodographs (sampled by regional VWP) will support organized storms including supercells (even if embedded in a line) with a risk of tornadoes, damaging winds, and large hail. A watch will likely be issued for parts of this area before 0230Z. ..Weinman/Thompson.. 03/25/2023 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...OHX...BMX...HUN...MEG...JAN...
