Areas of ifr local lifr conditions in fog will lift and dissipate
by 14z withVFR conditions then expected to prevail into early
tonight. Late tonight into Thursday morning some MVFR ceilings
will be possible with a couple of showers possible around the
tampa bay TAF sites toward morning.

short term (today through Thursday)...

a deep layer of low level moisture has helped fuel some patches
of fog across the area early this morning. As the temperature
continues to fall, this fog will continue to expand in coverage
and thickness, and a dense fog advisory may be needed before the
fog clears out after sunrise.

Regional satellite is showing a developing storm system in the
west central gulf of mexico associated with an amplified shortwave
trough that is digging into the region. This system is moving
considerably slower than it was forecast to earlier in the week,
and is now expected to remain in the gulf today and will only move
east into the florida peninsula late tonight and into Thursday.

As a result, rain chances will be rather limited today across the
forecast area while the most favorable moisture holds well to the
west. That said, an occasional shower or thunderstorm cannot be
completely ruled out this afternoon.

The trough and deeper moisture will shift east into the florida
peninsula tonight and Friday with building rain chances. Mid level
temperatures of -10c to -12c will also allow for enough
instability for a few thunderstorms to be mixed in with the
showers as well. With the deep moisture producing numerous clouds
in addition to the rain chances, temperatures should also be a bit
lower Thursday, only topping out in the upper 60s over the nature
coast where rain chances will be highest.

Mid-long term (Thursday night through Tuesday)...

a strong shortwave trough and upper energy to start the forecast
period in the E gulf and slowly move over the state. Complex
surface gulf storm system to slide over the area then into the w
atlantic through Fri with unsettled weather continuing. Fairly
deep moisture, enhanced surface forcing and mid upper dynamics to
produce a few rounds of light to moderate numerous showers and
embedded thunderstorms through Friday.

Eastern u.S. Longwave trough to come in phase as second shortwave
wraps over the region Sat then entire trough moves into the w
atlantic Sun with drying nw-n flow aloft. Surface high pressure to
build into the region Saturday with drying trend from N to s,
then reinforcing cool dry canadian airmass Sunday-Monday. Cool
late nov temps expected to remain slightly below seasonal averages
Sunday into Tuesday morning.

Marine...

an area of low pressure will develop in the central gulf of mexico
today and lift northeast into northern florida tonight and
Thursday. This will bring an increase in wind speeds over the gulf
waters, mainly from tampa bay north tonight and Friday, with
periods of cautionary or low end advisory level winds possible.

Conditions will improve Friday afternoon and evening as high
pressure builds back in over the gulf.

Fire weather...

humidity will remain well above critical threshold through the
rest of the week. Patchy fog will be possible again
tonight Thursday morning.

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.
