Discussion
Ongoing convection across much of south florida is expected to
continue throughout the remainder of the afternoon and into the
evening hours as unsettled weather begins to take precedence.

Focus of most of the storms will be across the gulf coast and lake
okeechobee region, though the atlantic waters and east coast metro
are not in the clear, especially as an inverted trough pushes
into south florida from the bahamas. Main hazards for the
remainder of today will be gusty winds, frequent lightning, and
small hail. Overnight lows tonight are forecast to be in the upper
70s to near 80 along the east coast with low to mid 70s
elsewhere.

Things get spicy overnight tonight into tomorrow as the
aforementioned inverted trough creeps towards south florida. The
environment will still feature ample moisture (pws in the 2.00 to
2.50 inch range) with additional moisture reinforcements coming
with the trough. A parade of mid-level vort maxima (most evident
in the 500 mb levels) march across the west coast of south florida
overnight as well, further aiding in the instability. To add to
this already complex forecast are relatively cool 500 mb temps.

Gfs guidance suggest temps to waver in the -8c to -9c range from
now through Monday with slightly warmer temps advecting in
afterwards (-6c to -7c Monday afternoon through the remainder of
the forecast period). To put these temperatures into scope, the
average 500 mb temp for this time of year is around -7.4c.

With all of this in mind, higher rain chances will be possible
Saturday night into Sunday morning compared to south florida's
normal diurnally driven weather pattern. Scattered to numerous
storms are forecast Sunday afternoon and Sunday evening,
especially as the atmosphere heats up. Main hazards besides the
routine lightning, gusty winds, and heavy rainfall will be the
concern for possible minor localized flooding, particularly for
urban areas.

Taking a quick side note for two sentences -- models are showing
a very brief and shallow coverage of the saharan air layer (sal)
Sunday with surface concentration at only about 20-40 micrograms
per cubic meter. Essentially this will need to be monitored in
regards to the precipitation size spectrum and potentially
stronger updrafts.

For the beginning of next week, Monday looks to be the quietest
day weather wise. A ribbon of drier air (pw's around 1.50 inches)
drags across the region but this is short lived as an approaching
mid-level trough and associated surface boundary pushes into the
region from the north. The amplification of the mid-level trough
axis continues to reach into the northeastern gulf of mexico by
late Wednesday into early Thursday. As the trough sits to the
north and west of our area and the ridge retreats a bit back into
the atlantic, the rest of the week could see quite the unsettled
weather pattern with scattered to numerous showers and
thunderstorms outside of the diurnal sea breeze norms. Eventually
by the end of the extended forecast period, high pressure will
attempt to regain control, but until we reach that point in time,
the pattern will bear watching for the potential of excessive
rainfall and gusty winds.

Marine
While the overall pattern with the ridge of high pressure at the
surface will keep a generally light southeasterly flow across the
area most of the period, there will be periods of unsettled
weather this weekend into next week that mariners should maintain
awareness of. In particular, the passage of a trough late tonight
through Sunday and the approach of another trough early in the
week could cause an increase in storms over the waters. The main
concern with any storms remains gusty winds, lightning, and heavy
rain.

Beach forecast...

the persistent southeasterly flow will continue to permit a non-zero
rip current risk along the atlantic beaches of south florida through
the weekend and into next week. It is possible, particularly if the
passing troughs into early next week develop a bit stronger wind and
create surges of southeasterly to easterly flow that could enable a
moderate rip current risk at times along the atlantic beaches.

Aviation
Showers and thunderstorms are ongoing and continue to develop over
the interior and west coast. MVFR ifr conditions for vis and CIGS are
possible for kapf with the gulf sea breeze developing. For the
east coast TAF sites most of the activity has moved west of the
terminals however there is additional development in the atlantic
moving towards east coast. Have reintroduced vcsh fll and points
southward to account for development in the atlantic moving nw.

Southeast flow will prevail throughout along east coast.

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.
