Areas affected...portions of southern Alabama and southwestern
Georgia into the western Florida Panhandle
Concerning...Severe potential...Watch possible=20
Valid 121655Z - 121830Z
Probability of Watch Issuance...60 percent
SUMMARY...The severe threat is increasing across portions of
southern AL/GA into the FL Panhandle behind the initial round of
storms. Damaging gusts and large hail are possible with the stronger
storms and a WW issuance may be needed within the next few hours.
DISCUSSION...Ample surface heating is taking place behind an initial
round of thunderstorms across portions of Southern AL and GA into
the FL Panhandle. The initial round of storms has left an outflow
boundary draped across the FL Panhandle, with a supercell meandering southeastward, just north of this boundary. Temperatures have
already warmed well into the 80s F, away from the outflow. Given low
to mid 70s F surface dewpoints, over 3000 J/kg MLCAPE is already in
place. In addition, unseasonably strong mid to upper flow is
contributing to 35-45 kts of effective bulk shear amid modestly
curved hodographs, capable of supporting multicells and transient
supercells this afternoon.=20
Severe potential should continue along the residual outflow boundary
and may increase this afternoon as more storms develop and interact
with this boundary. Additional storms should also develop along a southward-sagging cold front and sea-breeze boundary. Damaging gusts
and large hail are possible with any of the more mature storms that
develop and a brief tornado cannot be completely ruled out.
