Areas affected...Southern Mississippi...Southern Alabama...Western
Florida Panhandle
Concerning...Severe potential...Watch likely=20
Valid 130934Z - 131030Z
Probability of Watch Issuance...80 percent
SUMMARY...A wind damage, hail and an isolated tornado threat will be
possible for several more hours, as a line segment moves
east-southeastward from southern Mississippi into southern Alabama
and the western Florida Panhandle. Weather watch issuance will
likely be needed.
DISCUSSION...The latest hi-resolution radar from Jackson, MS shows
an organized line segment moving east-southwestward across southern Mississippi. This line is being supported by a shortwave trough,
evident on water vapor imagery, and is located along a gradient of
instability, where the RAP has MUCAPE in the 500 to 1000 J/kg range.
Along this west-northwest to east-southeast corridor, regional
WSR-88D VWPs and RAP forecast soundings have 0-6 km shear in the 60
to 75 knot range. This should continue to be favorable for storm
organization for several more hours. Wind damage will be possible
along the leading edge of the line. In addition, the WSR-88 VWP at
Fort Rucker, AL has 0-3 km storm-relative helicity around 350 m2/s2
suggesting an isolated tornado threat will also be possible. The
severe threat may increase along the leading edge of the line, if it
can become more surface-based.
