Concerning...Severe Thunderstorm Watch 421...

Valid 011703Z - 011900Z

The severe weather threat for Severe Thunderstorm Watch 421
continues.

SUMMARY...Isolated severe wind gusts remain possible in association
with a line of storms moving from eastern Alabama into western
Georgia. Storms along the coastal Florida Panhandle may produce a
severe wind gust as well.

DISCUSSION...A broken line of storms currently stretches from the
Al/GA/TN tri-state area southward along the AL/GA border and into
the western FL Panhandle. Much of this activity has been relatively
low-topped owing to weak instability, but strong lift along the
leading outflow has been able to breach a weak inversion just above
850 mb. Pockets of heating, as well as the northward advection of
65-68 F dewpoints should maintain current instability levels of a
few hundred J/kg MUCAPE. Some of the activity may not produce
lightning, but gusty winds are likely along the line. A few surges
of stronger wind gusts are possible to 40-50 kt. A brief/weak
tornado cannot be ruled out, but the primary threat will be strong
wind gusts.
