Mesoscale Discussion 1599
NWS Storm Prediction Center Norman OK
1200 PM CDT Sun Jul 12 2026
Areas affected...portions of North Florida and the Florida Panhandle
into southwestern Georgia and southeastern Alabama
Concerning...Severe potential...Watch unlikely
Valid 121700Z - 121900Z
Probability of Watch Issuance...20 percent
SUMMARY...Isolated damaging wind gusts and perhaps an instance or
two of small hail will be possible over the next several hours.
DISCUSSION...Scattered thunderstorms have developed along the Gulf
Coast sea breeze from the Florida Panhandle into North Florida amid
a hot and humid air mass, with a couple of gusts measured in the
40-45 mph range over the past 1-2 hours. Temperatures near 90 F and
dewpoints in the low/mid 70s are already supporting 2000-3000 J/kg
MLCAPE, with further destabilization expected through peak heating
this afternoon. Coupled with high PW (greater than 2 inches) and
steepening low-level lapse rates, an isolated risk for water-loaded
downbursts, damaging wind gusts (with localized gusts to 65 mph
possible), and perhaps an instance or two of small hail should
materialize across the region. Weak effective shear and deep
layer-flow will temper overall convective intensity and
organization. Thus, watch issuance appears unlikely at this time.
