Areas affected...Southeast Alabama...Georgia
Concerning...Tornado Watch 10...11...12...
Valid 160901Z - 161130Z
The severe weather threat for Tornado Watch 10, 11, 12 continues.
SUMMARY...A potential for severe gusts and a few tornadoes will
likely continue for a few more hours over parts of southeast Alabama
and western to central Georgia.
DISCUSSION...The latest water vapor imagery shows a plume of
mid-level moisture over the central Gulf Coast states, which is
associated with a shortwave trough and ongoing squall line. The line
is located from Mobile, Alabama north-northeastward to near Atlanta,
Georgia and is just ahead of a fast-moving cold front. Ahead of the
line, surface dewpoints are in mostly in the 60s F, with mid to
upper 50s F over north-central Georgia. The RAP shows weak
instability ahead of the squall line, with MUCAPE generally near or
below 500 J/kg across much of southeast Alabama and western Georgia.
The WSR-88D VWP ahead of the line at MXX near Auburn, Alabama shows
very strong speed shear in the boundary layer with winds increasing
to around 70 knots at one kilometer above ground. For this reason,
it will not be hard for the more organized parts of the line to
produce severe gusts. In addition, storm-relative helicity is very
strong, which should enable a tornado threat to continue. However,
the tornado threat will remain isolated, mainly due to weak
instability and the lack of discrete cells ahead of the squall line.
As the line moves eastward, a slow downtrend in the overall severe
threat is expected.
