...Unseasonably Warm Temperatures Expected Through Wednesday...
...Some Sea Fog Possible Tonight Through Early Wednesday...

.UPDATE...
An unseasonably warm and moist air mass will continue across the
forecast area through mid week as high pressure from the Atlantic
extending west across the peninsula remains in control. The warm
and moist air mass overriding the cool Gulf waters may support
some patchy sea fog later tonight, with even better chances Tuesday
night as higher dew point air moves into the region ahead a cold
front approaching from the west. In addition to the sea fog patchy
to areas of land fog are forecast to develop with some locally
dense fog possible toward daybreak. It will be another very mild
night with overnight lows in the lower 60s. On Tuesday the low
clouds and fog should gradually burn off over the land area by
late morning, with warm and dry conditions expected for the
remainder of the day with afternoon temperature climbing into the
lower 80s area-wide. The exception to this will be over the
adjacent Gulf waters and right along the immediate coast where sea
fog may linger through the day resulting in less sunshine and
slightly lower temperatures. Overall the current forecast is in
good shape with no changes or evening update required at this
time.

.AVIATION...
VFR conditions early tonight will give way to MVFR/IFR cigs/vsbys
after 07Z with localized LIFR cigs/vsbys possible between 08-12Z
as low clouds and fog develop over the region. VFR should return
after 16Z as the low clouds and fog burn off, but sea fog may
remain an issue for the northern coastal terminals of KTPA, KPIE,
and KSRQ through the day, but due to the uncertainty of its
overall impacts at this time will depict VFR returning to these
sites as well after 16Z. South to southwest winds in the 5 to 7
knot range the rest of tonight, will increase to 9 to 12 knots
after 16Z on Tuesday.

&&

.MARINE...
An unseasonably warm and moist air mass overriding the cooler Gulf
shelf waters will support some sea fog development over the waters
later tonight through Wednesday night which will produce some hazardous
marine conditions for mariners. As for winds and seas, winds should
continue from the south and southwest around 10 knots the remainder
of tonight through Tuesday night with seas of 2 to 3 feet. Ongoing
forecast is on track with no changes expected in the next forecast
issuance around 9 PM.
