   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.
