.AVIATION...
(06Z TAFS)
Issued at 1255 AM EST Sun Dec 17 2023
Inclement conditions continue across terminals as low pressure
over the E Gulf continues NE, with warm front over C FL and
trailing cold front over E Gulf. Showers and storms expected to
continue impacting terminals, with the main band preceding cold
front as the primary concern generally through around 10Z or
shortly thereafter. Gusty winds expected, increasing as winds turn
onshore as the cold front passes through, likely around or just
above 20 knots with higher gusts before diminishing later in the
afternoon. Will need to monitor TPA/PIE through morning into
perhaps early afternoon for potential Airport Weather Warning
necessity should winds verify higher near issuance threshold.
Otherwise, expect restrictions with MVFR/IFR cigs/vsbys given
convection ahead of front, with post-frontal sub-VFR cigs as
cooler, stable air mass works across terminals.
