Areas affected...Alabama...Georgia
Concerning...Tornado Watch 215...216...
Valid 091248Z - 091445Z
The severe weather threat for Tornado Watch 215, 216 continues.
SUMMARY...An isolated wind damage/tornado threat should continue
this morning across northern Alabama and northern Georgia. The
threat may spread southward into central Alabama and central
Georgia, where new weather watch issuance remains possible.
DISCUSSION...The latest mosaic radar imagery shows an MCS,
associated with strong to severe storms, located from far northeast
Mississippi extending eastward into far western South Carolina. A
moist and unstable airmass is present to the south of the MCS across
much of the Gulf Coast states. In addition, regional WSR-88D VWPs
across this airmass have 0-6 km shear near 60 knots and 0-3 km
storm-relative helicities between 200 and 250 m2/s2. This should
support an isolated tornado threat with supercells embedded in the
line, or that develop to the south of the line. A wind-damage threat
will also be possible with the supercells and the stronger line
segments. The severe threat is expected to increase later this
morning as surface temperature warm. For this reason, weather watch
issuance may be needed to the south of the current watches.
