Mesoscale Discussion 1481
NWS Storm Prediction Center Norman OK
0145 PM CDT Thu Jul 14 2022

Areas affected...Portions of north FL and southern GA

Concerning...Severe potential...Watch unlikely

Valid 141845Z - 142115Z

Probability of Watch Issuance...5 percent

SUMMARY...Occasional strong to damaging winds may occur as
thunderstorms spread eastward this afternoon. Watch issuance is not
expected.

DISCUSSION...Scattered to numerous thunderstorms have developed
along/south of a front across parts of north FL and southern GA.
Weak low-level flow strengthens very modestly at mid/upper levels
based on recent VWPs from KTLH/KVAX, with a general eastward
co*ponent to ongoing activity. A moderately unstable and moist
low-level airmass, with MLCAPE around 2000 J/kg, is present across
the warm sector. Low-level lapse rates are beco*ing modestly
steepened as strong diurnal heating continues, and occasional strong
to damaging winds will be possible with any convective downdrafts.
Regardless, weak effective bulk shear should limit overall
convective intensity and organization through the rest of the
afternoon, with pulse to loosely organized multicell thunderstorms
possible. Therefore, watch issuance is not expected.
