Areas affected...Tennessee...Northeast Mississippi...Northern
Alabama...Far Northwest Georgia
Concerning...Tornado Watch 213...214...
Valid 090710Z - 090915Z
The severe weather threat for Tornado Watch 213, 214 continues.
SUMMARY...A threat for wind damage, isolated large hail and a few
tornadoes will continue across western and middle Tennessee over the
next couple of hours. The threats are expected to spread into parts
of northeast Mississippi, northern Alabama and far northwest
Georgia. A short-term extension or new weather watch issuance will
be needed as the expiration of WW 213 approaches at 08Z.
DISCUSSION...The latest hi-resolution radar imagery from Nashville,
TN shows a large MCS with numerous severe storms, located across the
Tennessee Valley. An undisturbed airmass is currently evident from
southern middle Tennessee southward into the northern Gulf Coast
states, where the RAP is analyzing MLCAPE in the 1500 to 2500 J/kg
range. The Huntsville, AL WSR-88D VWP has 0-6 km shear near 40
knots, with 0-3 km storm-relative helicity of 300 m2/s2. This will
support a tornado threat, with discrete supercells that remain out
ahead, or with the more intense cells embedded within the MCS.
Supercells could also be associated with an isolated large-hail
threat. A wind damage threat will also be likely, especially with
bowing line segments.
