SPC Mesoscale Discussion: Severe Thunderstorm Watch 421…

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.
