National Weather Service Tampa Bay Ruskin Florida
807 PM EST Monday Dec 22 2014

For the evening update...
a warm front was located across north central Florida and was
producing scattered showers and isolated thunderstorms. Bulk of
the shower activity was located north of the forecast area...but
there will be a chance of showers and thunderstorms north of Tampa
overnight...with the best chance across Levy County. The warm
front will gradually lift north tonight and Tuesday. South of the
frontal boundary...warm moist air is in place across west central
and southwest Florida with dew points in the upper 60s...with
lower 70s over the coastal waters. The high dew point air
advecting over the relatively cooler waters of the eastern Gulf of
Mexico will allow sea fog to develop tonight which will likely
persist into Tuesday and may move locally onshore. Areas of fog
will likely form over west central and southwest Florida after
midnight and may be locally dense late tonight into early Tuesday
morning. Will update zones to add potential for locally dense fog
tonight.

Aviation...
VFR conditions this evening...then MVFR ceilings/visibilities likely
developing at all terminals after midnight with local IFR ceilings/visibilities
due to fog late tonight/early Tuesday morning.

&&

Marine...
numerous marine hazards to continue this week. Several rounds of
showers and thunderstorms will continue to move over the
northeastern Gulf waters tonight through midweek ahead of a potent
storm system. Southerly and southwesterly winds will bring a warm
and humid airmass over the cold shelf waters to produce areas of
sea fog tonight and continuing through middle week. Moderate
southerly winds will keep seas in the 3-5 feet range tonight into
Tuesday. Then stronger southwest-west then northwesterly winds
will elevate rough and choppy hazardous seas Wednesday-Thursday into Small
Craft Advisory conditions. High pressure will build into the
region to end the week with winds and seas subsiding by the
weekend.
