Watch issuance is considered unlikely at this time. DISCUSSION...At 2330Z, extensive convection is ongoing from southwest GA into the northern Gulf of Mexico, in association with a cold front. The front/outflow is tending to undercut convection across the northern FL Panhandle, where the line is oriented southwest-to-northeast. However, the storm cluster over the northern Gulf of Mexico has more of a north-south orientation, which should prevent frontal undercutting in the near term. Downstream of this convection from Panama City to near Apalachicola, modest diurnal heating of a moist environment has resulted in MLCAPE increasing into the 500-1000 J/kg. Weak midlevel lapse rates will continue to limit updraft intensity, but with favorable low-level and deep-layer shear in place (as noted in the KEVX VWP), some threat for locally damaging gusts and/or a brief tornado may materialize as this convection moves onshore. If any small discrete cells forming ahead of the line can mature into supercells, they may pose a brief tornado threat as well, though this scenario is also rather uncertain.=20 At this time, the threat is expected to remain relatively limited in magnitude and areal coverage, rendering watch issuance unlikely. ...Dean/Goss.. 03/17/2023 ....Please see https://urldefense.com/v3/__http://www.spc.noaa.gov__;!!DZ3fj= g!9BNzFTiux_KubW9YLZFfb8paf4TflDDF6Yo67OGkEPllVfRhIeqUJbukKXAC250YpLuDDZyS9= D_7tALJveEqZ3y-G8Y$ for graphic product...
