Aviation
24/12z-25/12z. Cold front approaching tampa bay with low clouds
and a few showers. Tafs have MVFR CIGS that spread south then lift
around mid-afternoon to bknVFR. Shra too isold to mention. Winds
currently westerly and modest but will increase and become gusty
in the wake of the front.

Gusty winds with slightly cooler temperatures expected today
Short term (today - Tuesday)...

water vapor loop shows a closed upper level low over north-central
alabama early this morning. This closed low and an attendant weak
surface low over northeast georgia will move off the southeast u.S.

Coast through early tonight, and will then lift slowly north up
along the eastern seaboard through Tuesday. A trailing cold front
from this storm system now over the big bend region will continue to
move south moving through the nature coast toward sunrise, and then
through the bay area during mid morning, and then exiting to the
south of the forecast area during early afternoon.

Limited moisture along and ahead of the front should only support
some isolated showers (pops 20 percent) through early afternoon with
its passage with limited rainfall amounts expected. As the front
moves through northwest winds will increase and become gusty by mid
to late morning and into the afternoon which will make for hazardous
boating conditions on the adjacent gulf waters as well as on area
lakes. In addition to the winds considerable post-frontal moisture
via model cross-sections will support a good deal of clouds (mostly
cloudy skies) across the region through the day, especially along
the coast.

Given the expected increase in winds will hoist a lake wind advisory
for the area lakes from noon through early this evening. Cool air
advection in the wake of the front combined with considerable post
frontal cloudiness will support cooler temperatures across the
region today compared to previous days with highs topping out in the
mid 70s north, and upper 70s to around 80 central and south.

Tonight drier air in the wake of the front will support clearing
skies and cooler conditions across the entire forecast area with
slowly diminishing winds as weak high pressure takes hold, with
overnight lows falling into the upper 50s across the nature coast,
and around 60 to the lower 60s central and south.

On Tuesday zonal flow aloft and weak surface high pressure will
support pleasant dry weather across the forecast area with ample
sunshine. Temperatures on Tuesday will return to near seasonal norms
with afternoon highs reaching around 80 to the lower 80s area wide
during the afternoon with west wind in the 10 to 15 mph range.

Long term (Tuesday night - Sunday)...

by the middle of the week, a shortwave trough positioned over the
carolina coast will be moving away from florida, while weak mid-
level high pressure over the gulf of mexico slides east into
florida. At the surface, atlantic high pressure ridging across the
florida straits Tuesday night will gradually lift north into florida
through the rest of the week, keeping dry and stable conditions in
place. With the high pressure building into the area both at the
surface and aloft, temperatures will increase through the second
half of the week, with maximum temperatures forecast to reach into
the low 90s inland and upper 80s along the coast each afternoon
beginning on Thursday.

By the end of the week, the upper level pattern will become much
more meridional as a deep trough digs into four corners region and
the ridge over florida amplifies. This more dynamic pattern will
bring in increased atmospheric moisture from the gulf and allow for
a slight chance of showers both Saturday and Sunday afternoons,
although there does not look to be enough instability to allow for
heavy or widespread rainfall anywhere in the area.

Marine...

a storm system over the southeast u.S. This morning will help to
pull a cold front south through the eastern gulf waters today. As
the front moves south through the waters winds will become northwest
with speed increasing into the cautionary range by mid to late
morning with hazardous marine conditions developing for small craft
operators. Given these expected conditions will raise cautionary
headlines for all of the waters in the next marine forecast package
later this morning. In addition, the gusty onshore flow and building
seas and surf with bring a high risk of rip currents to area beaches
this afternoon through early Tuesday morning and will issue a
coastal hazard message to address the threat of rip currents later
this morning.

Tonight into Tuesday winds will back to the west as the above
mentioned storm system lifts slowly out to the north along the
eastern seaboard with wind speeds diminishing into the 10 to 15 knot
range. During Wednesday through Friday high pressure from the
atlantic extending west across the central peninsula will support a
lighter southeast to southerly wind flow over the gulf waters with
an onshore sea breeze component developing along the coast each
afternoon.

Fire weather...

despite some drier air moving into the region today in the wake of a
cold front humidity values are expected to remain above critical
levels. On Tuesday and through the remainder of the week some
pockets of humidity values at or below 35 percent will be possible
over interior locations each afternoon, but lighter winds and erc
values below critical levels should preclude red flag conditions.

Gusty 20 foot winds and transport winds today will support high
dispersion indices across the region. The strong and gusty winds
will also create hazardous conditions near any ongoing fires around
the region. Winds are expected to slowly diminish on Tuesday and
through the remainder of the week as high pressure builds in over
the region.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
