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.

Aviation
Patches of fog, some locally dense have already developed
over parts of the area and are expected to increase in
coverage and density through sunrise. Periods of ifr or lifr
visibility and ceilings will be possible through just after
sunrise. The one limiting factor will be a large area of
cirrus moving east into the area, which could bring some
relief from the fog. MVFR ceilings may linger through the
morning, then scattered showers will be possible again after
17z, mainly around the tampa bay and areas to the north.

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.
