Today-tonight: one more relatively quiet day across south florida
as the ridging at the surface and aloft begin to break down.
Increasing south-southeasterly flow will usher in a few more
afternoon clouds and keep temperatures warm in the mid-upper 80s,
with the potential for a few 90 degree readings across glades,
hendry, and interior collier counties. While the gulf coast breeze
is still expected to develop this afternoon, it will be much
weaker, later in the day, and not move as far inland as earlier
this week. Similar to the past few days, while a shower or two
can't be ruled out with the evening sea breeze collision, chances
remain too low for a mention in the forecast.
Friday-Sunday: the track of the upper level and surface low
moving across the tn/oh valley and mid-atlantic late week has
shifted further north. With the surface front so far removed from
its parent low, it will be losing a lot of its momentum as it
moves into florida on Friday. Deep moisture return also looks less
robust, especially given the dry airmass currently in place that
needs to be modified.
However, gusty southerly flow will lead to a modest increase in low
level moisture across the region, which along with a robust 90-100kt
jet crossing the peninsula, above normal daytime highs in the mid
80s, and surface convergence with the dying front, will help
generate a few afternoon showers and storms as the front moves into
south florida Friday afternoon. Overall rain chances are lower
than previous forecast, focused towards the east coast, where a
weak seabreeze will help with convergence.
Front is expected to wash out across south florida/fl straits into
Saturday. This will leave some lingering moisture that may generate
isolated showers and a storm or two with daytime heating and the
seabreeze collision Saturday and Sunday afternoons.
Next week: the southern stream jet remains active into next week
with the next upper level low swinging through the southern tier of
the us into Monday and another robust surface low expected to move
into the tn/oh valleys and mid-atlantic Monday-Tuesday. Timing
differences remain in the approach of the next front(s), but it
appears there will be at least low end threat for afternoon showers,
and potentially thunderstorms into mid next week.
Marine Southeasterly flow picks up today ahead of the next system
through the end of the week, becoming 10 to 15 kts today, and more
southerly at 15 to 20 kts on Friday. The front is expected to bring
some showers, and maybe even a few thunderstorms to south florida
waters on Friday.|
Winds become light and somewhat variable as the front washes out
over the region into Saturday with both the east coast and gulf
seabreezes dominating the wind pattern. Winds are expected to
increase out of the southeast again Sunday and Monday ahead of
another approaching system.
Aviation Light and variable winds withVFR conditions will
prevail through the overnight hours across south florida.
Southeast winds begin to increase to around 10 knots by mid day
with a few brief gusts up to 15 knots. Gulf sea breeze will shift
winds southwest in the afternoon over apf but return to the
southeast by the evening hrs. As the next front moves closer into
the area tonight, expect winds to remain around 10 to 15 knots
along the coastal areas.
Fire weather Dry conditions continue across the region today,
though a little stronger southeasterly flow will help modify
locations east of lake okeechobee this afternoon. Afternoon rh
values are expected to drop below 40% across glades and hendry
counties for 4-6 hours this afternoon. Inland collier county may
also see a few hours around 40%. While winds speeds will be a
little stronger this afternoon, with dispersions in the good to
very good range, overall they are expected to remain less than 10
mph. Due to longer duration of rh, the fire weather watch has been
upgraded to a red flag warning for glades and hendry.
The approach of a frontal boundary along with a few showers and
storms will bring a modest increase in rh values on Friday and
Saturday. Drier conditions behind the front may allow interior
locations to see rh values back into the mid 30%-low 40% range
across glades, hendry, and interior collier counties on Sunday.

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.
