Current-Today...Stubborn fog/stratus to continue to slowly burn off
thru mid/late morning. Strong deep layer ridging continues over the
area providing for generally clear skies aloft, with moisture
trapped near the surface, light/calm winds, and enough subsidence
for fog promotion early this morning. Else, weak surface high
pressure ridging remains aligned east-west oriented over the central
FL peninsula today. Weak pressure gradient in place will promote
light surface winds. Conditions will remain dry.

High temperatures into the lower 80s most areas, except U70s to
around 80 degrees immediate east coast. We continue several degrees
above climo. Will update zones shortly to clean up first period

Tonight...Previous...Very light to calm winds and mostly clear skies
will combine with dewpoints holding in the low to mid 60s to produce
another round of fog. Mild overnight with lows between 60-65 which
is a good 10 degrees above climatology.


.AVIATION...Stubborn fog/stratus continuing to slowly burn off with
improving conds thru mid/late morning at local TAF sites. Weak
pressure gradient in place with light winds today. VFR after
fog/stratus burns off, continuing into late evening. Then another
round of fog formation with some stratus with favorable conditions
for this once again overnight into Tue morning. Expect IFR/LIFR
cigs/vsbys late overnight/Tue morning.


.MARINE...Today/Tonight...Low-level ridge axis across the central FL
coastal waters. The pressure gradient remains weak with light winds.
Light S/SSW winds will become onshore near the coast during the
afternoon, remaining light. A light offshore component will develop
once again this evening/overnight as position of the ridge axis
moves across our southern marine legs. Wind speeds AOB 10 kts. Seas
2 ft in mainly an east swell.
