Concerning...Tornado Watch 722...723...

Valid 290721Z - 290815Z

The severe weather threat for Tornado Watch 722, 723 continues.

SUMMARY...Primary corridor of tornado potential through the pre-dawn
hours should exist from southeast of Montgomery, east-northeast
along the I-85 to I-75 corridors in Alabama/Georgia.

DISCUSSION...After merger of a long-track supercell with the
extensive QLCS near the Montgomery area of AL, an embedded bowing
structure with mesovortices has formed and recently produced a brief
TDS per the MXX 88D. The downstream evolution of this
bow/mesovortices will likely contain greater tornado potential
within WWs 722/723 during the next few hours. The MXX VWP has
sampled a rather enlarged low-level hodograph with 0-1 km shear from
35-40 kts. MLCAPE around 500 J/kg should gradually spread
east-northeast as surface dew points slowly increase through the mid
60s from southeast AL/south GA.
