The severe weather threat for Tornado Watch 124 continues.
SUMMARY...Tornadic supercell potential will likely focus near the
AR/MO border through 8am. A strong tornado is possible.
DISCUSSION...A pair of discrete supercells have developed over the
Ozarks ahead of a broken squall line located on a cold front. The
airmass ahead of the squall line in the warm sector is moderately
unstable (2500 J/kg MLCAPE) and features a moisture-rich low-level
airmass (upper 60s dewpoints over northern AR). Rapid storm motions
(50 kt to the northeast) indicate around 450 m2/s2 0-1km SRH is
present over northern AR per KLZK VAD data. As these supercells
continue to mature and cycle, the tornado risk will probably
increase with one or both of the supercells. A strong tornado
(EF2-EF3) is possible.
