Concerning...Severe Thunderstorm Watch 225...226...227...
Valid 100613Z - 100815Z
The severe weather threat for Severe Thunderstorm Watch 225, 226,
227 continues.
SUMMARY...Wind damage, hail and a brief tornado will be possible as
an MCS moves southeastward across the central Gulf Coast region late
tonight. New weather watch issuance will likely need to be
considered as the MCS approaches the southeastern edge of the
ongoing watches.
DISCUSSION...The latest mosaic radar imagery shows a well-developed
MCS from south-central Alabama extending west-southwestward into
southwest Mississippi. The MCS is located on the northern edge of a
strongly unstable airmass centered over the central Gulf Coast.
Across this airmass, MLCAPE is estimated by the RAP in the 2500 to
3500 J/kg range. In addition, regional WSR-88D VWPs have 0-6 km
shear near 50 knots which will be favorable for supercells and
bowing line segments, in or ahead of the MCS. Wind damage will be
likely along the more intense parts of the line. Also, the WSR-88D
VWP in southeast Alabama has 0-3 km storm-relative helicity in the
200 to 250 m2/s2 range. This should support an isolated tornado
threat with supercells and with rotating cells embedded in the line.
The threats should continue to move along the instability gradient,
eventually affecting parts of far southern Mississippi, far southern
Alabama and the Florida Panhandle. New weather watch issuance may be
needed across this area late tonight.
