NWS Storm Prediction Center Norman OK
0456 PM CST Sun Jan 09 2022
Areas affected...parts of southeastern MS...southern AL...the FL
Panhandle...and southwest GA
Concerning...Severe potential...Watch unlikely
Valid 092256Z - 100100Z
Probability of Watch Issuance...20 percent
SUMMARY...The severe threat will continue spreading southeastward of
WW14, though the localized and brief nature of the threat will
likely preclude watch issuance.
DISCUSSION...Scattered thunderstorms will continue spreading
southeastward into parts of southeastern MS, southern AL, the FL
Panhandle, and southwest GA over the next few hours, where a moist
boundary-layer (lower 70s dewpoints) and southerly surface winds are
contributing to moderate surface-based instability. VWPs across the
pre-convective warm sector indicate favorable low-level hodographs,
with 0-1 km SRH of 150-200 m2/s2 and 0-6 km bulk shear of 50-60
knots. These factors may support a brief continuation of organized
convection prior to being undercut, with a mix of supercell
structures and linear segments possible. The primary risk will be
isolated wind damage, though a brief tornado will also be possible
with any discrete and longer-lived convection. At this time, a new
watch is not anticipated owing to the localized and brief nature of
the threat.
