Due to the increase and duration of the southerly fetch Thursday and Thursday night...seas trend higher. Thunderstorms increase in coverage. The front looks to make passage early Friday morning...bringing a moderate westerly flow during the day Friday in its wake. Onshore flow returns over the weekend and shows a greater increase by Sunday.

A couple of showers possible early this evening with late sea
breeze collision over the middle of the everglades between
alligator alley and tamiami trail, otherwise a dry and mild night
is in store. Patchy fog expected after midnight over the interior
to just inland of the gulf coast. All forecast elements on track
and no updates needed.

the winds will be light and variable tonight into Wednesday
morning over all of south florida TAF sites. The ceiling and vis
will also remain in theVFR conditions along with dry weather at
all of south florida TAF sites.

Fair weather through at least Thursday
near-term (this afternoon and tonight): weak mesoscale low
pressure off the palm beach county coast this afternoon causing a
few showers over the gulf stream. Otherwise, light background
synoptic pattern promoting inland penetration of both east and
west coast sea breezes this afternoon, but with dry air
predominating, little in the way of showers anticipated except
for maybe an isolated shower or two over the everglades south of
alligator alley. Light winds and mostly clear skies tonight will
be favorable for patchy fog over interior sections, mainly during
the pre-dawn and sunrise hours.
Short-term (Wednesday through Friday): high pressure surface and
aloft will dominate the weather pattern across florida through
Thursday as area in between low pressure systems over the SW united
states and new england. Weak pressure gradient on Wednesday once
again will lead to sea breezes pushing inland during the afternoon,
but dry air in place will limit if not completely prevent any
showers. Patchy fog possible late Wednesday night and early
Thursday over interior sections. On Thursday, high pressure shifts
east of area as upstream low pressure system enters the gulf of
mexico. Low level flow will become southeast with the gulf sea
breeze not pushing as far inland as previous days. Although
suppressing influence of the high pressure will diminish on
Thursday, still not enough moisture for more than perhaps an
isolated shower or two. On Friday, the low pressure system moves
across the southeast united states, but the associated mid/upper
level trough becomes less amplified as it approaches florida. As a
result, possible area of showers and thunderstorms over the gulf
of mexico early in the day on Friday may weaken substantially as
it nears south florida, but enough increase in low level moisture
with the s-sw wind will support at least low-end chance of showers
Friday afternoon. Will have to watch for potential of more
organized convection holding together enough for more widespread
activity affecting parts of the area, but we have time to monitor
Temperatures will remain a few degrees above normal for late
march, with highs in the 80s and lows in the upper 50s and 60s.
Dry air will keep dewpoints and relative humidity values on the|
low to moderate side.
Extended period (Saturday through early next week): mid/upper
level trough departs on Saturday, with lingering moisture trailing
back over area leading to a chance of showers. Sunday looks a
little drier before moisture surges back into area early next week
in association with next mid/upper level trough moving across the
southeast united states. For now models showing this next system
to be similar to the one expected on Friday, which means a better
chance of showers along with increasing south-southeast winds.
Temperatures expected to warm up a bit this upcoming weekend, and
we may see a few 90-degree readings over the interior along with
mid 80s over the metro areas along both coasts. Remaining warm
into early next week, along with increasing humidity levels.
generally good boating conditions expected through Wednesday
(wind generally 10 knots) before winds gradually increase
Thursday and especially Friday. Winds on Thursday will be in the
10-15 knot range, highest over the near shore atlantic and gulf
waters. By Friday, southeast winds will be in the 15-20 knot range
over most of the local waters along with seas building to 3-5 ft.
Wind and seas look to decrease in time for the upcoming weekend,
then increasing again by early next week ahead of the next low
decent beach conditions expected through Thursday with the rip
current risk staying on the low side, expect borderline moderate
risk for the palm beaches due to a small northeast swell. The rip
current risk will increase on Friday as southeast winds pick up,
possibly lingering into at least the first part of the upcoming
dry air in place across south florida along with little if any
precipitation through Thursday will lead to some fire weather
concerns, particularly a result of low relative humidity values in
the 35 percent range over the interior (glades county through
inland collier county). Although fuels are quite dry, forecast wind
speed and duration of critical relative humidity values are
at worst marginal for red flag warning conditions. Future shifts
will evaluate the need for warnings if trends show lower humidity.

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.
