Areas affected...Portions of east-central AL and west-central GA

Concerning...Tornado Watch 21...

Valid 221831Z - 221930Z

The severe weather threat for Tornado Watch 21 continues.

SUMMARY...A cluster of intense storms will spread across portions of
east-central AL into west-central GA through mid-afternoon.

DISCUSSION...A cluster of thunderstorms spreading eastward and
northeastward across portions of central AL is exhibiting forward
motion around 35-45 kt, with linear extrapolation suggesting its
leading edge crossing into GA around 2030-2200Z. This activity is
evolving within a region of strong deep ascent associated with the
left-exit region of a midlevel speed maximum. While this activity
lies to the north of the most unstable air presently confined to
southern AL/GA, the 18Z Birmingham sounding indicates sufficient
buoyancy amidst around 60-70 kt of deep shear for a continued severe
risk with this activity. Damaging winds and tornadoes will be
possible, especially owing to rapid intensification of the surface
low in proximity to the area.

Cells are looking ominously discrete now from SE AL into the FL panhandle. Scary situation unfolding.
 
New tornado warning for a strong couplet just west of Union Springs. Looks like there might be a couple of other small areas of rotation to the north of there.

EDIT: Confirmed tornado.
 
Wow, the mesolow is starting to remind me of the morning system on 4/27/11 with the multiple embedded circulations and the strong rotating cells near its core. This is a dangerous but very fascinating situation unfolding over east central AL...
 
Got some storm mergers going on with the main line. Hopefully could limit some of the tornado potential as inflows get disrupted but still a VERY potent set up.
 
Pressure reading here just west of Jasper is at 990.7mb/29.22in. That's one of the lowest readings in many years that I've noted outside of tropical systems this far inland.
 
These non-warned storms in Shelby Co are pretty fierce!!
