Areas affected...Parts of southern Georgia into northern Florida

Concerning...Severe potential...Watch unlikely=20

Valid 212214Z - 212345Z

Probability of Watch Issuance...5 percent

SUMMARY...Locally strong gusts and/or marginally severe hail could
occur with a couple isolated storms over the next couple hours.

DISCUSSION...A couple isolated storms have developed across far
southern GA -- immediately ahead of a cold front draped across the
area. These storms are tracking slowly southeastward into northern
FL -- where earlier heating of a moist boundary layer (middle 70s
dewpoints) has yielded moderate surface-based instability. Given
30-40 kt of midlevel westerly flow sampled by the JAX VWP, these
cells may continue to exhibit marginal/transient supercell
characteristics -- and locally strong gusts/marginally severe hail
will be possible for the next couple hours.
