Vfr conditions should prevail, although a few late afternoon
through mid-evening showers are possible along the east coast as a
weak cold front moves in. Wind flow very light today and sea-
breeze dominate, thus nearly calm wind this morning becoming
onshore at less than 10 kt this afternoon, then light N calm
tonight behind the weak front.

today and tonight: a few areas across the western interior may
see some shallow patchy fog this morning. A few spots have already
reported reduced visibility. Today, high pressure that has been
dominating our weather pattern will break down and erode this
morning allowing for a weak frontal passage across the area later
today. While we will not see a noticeable change in temps, there
will be an increase in low-level moisture to help increase rain
chances today. Scattered showers will be possible in the afternoon
an evening particularly over northern portions of the region
around lake okeechobee and the east coast. With diabatic heating,
there will be some weak buoyancy ahead of the front and low-level
instability, even though model sounding lapse rates are fairly
weak a few weak thunderstorms are possible. Therefore, have
introduced slight chance of thunderstorms over the lake
okeechobee region, the northern half of east coast metro and the
atlantic waters. Any storms that do develop will be fairly weak
with occasional lightning strikes as the main hazard.

Overnight, any remaining showers and storms will be focused over the
atlantic waters with temperatures in the low 60s around the lake
okeechobee region to mid 60s along the gulf coast, to around 70
degrees for the east coast metro.

Short term (Wednesday - Thursday): drier air and across the region
briefly on Wednesday with temps still in the mid 80s and just a
little less humid. For thanksgiving day forecast models differ on
the amount of moisture, precipitable water across the region. The
gfs is much more aggressive than the ECMWF with a shortwave
moving through the area with increased chances of showers and
potential thunderstorms however has been trending downward with
the last few runs. The ECMWF keeps the holiday drier with the vort
shortwave barely existent. Tending to lean towards the ECMWF at
this time with just a slight chance of showers for the holiday.

High temperatures on Thursday will be right around normal this
time of year in the low 80s.

Long term (Friday through early next week): Friday through the
holiday weekend will see temperatures rise as we move through the
weekend back into the mid 80s. A low pressure system across the
northern gulf and florida panhandle will have a cold front draped to
its south. As of now, the low will work its way up the eastern
seaboard and it looks like the front will stall across the lake
okeechobee region and not make it into south florida. With
moisture ahead of the front will keep a slight chance of showers
in the forecast through the weekend into early next week.

a chance of showers throughout the forecast period with a
slight chance of thunderstorms today over the atlantic waters. Seas
will be generally 2 feet or less in the gulf and around 2 feet, up
to 3 feet in gulf stream, the next few days over the atlantic
waters. Northeasterly winds will increase Wednesday, higher seas in
the atlantic waters towards the end of the week with a northerly
swell.

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.
