Vfr conditions will prevail, and any bkn ceilings associated with
the inland-penetrating seabreezes this afternoon will be
primarily in the 4,000-5,000 ft range. Sea breeze over SE florida
metro terminals as of 18z, and should move through inland sites by
20z, whereas gulf seabreeze should be well inland of kapf this
afternoon. Patchy fog from about 09z-13z mainly over interior
peninsula but could affect ktmb and kapf with brief MVFR
conditions.VFR and SW wind 8-10 knots expected for Saturday.

Prev discussion issued 943 am est Fri feb 15 2019
update...

a few showers have been affecting parts of metro broward and palm
beach counties as well as the gulf stream waters this morning
caused by convergence of overnight land breeze and light ne-e wind
over the atlantic. For this reason, added in a slight chance of
showers for coastal SE florida and the atlantic marine zones.

These showers should dissipate this afternoon as the sea breeze
circulation diminishes the convergence over the water. Inland-
penetrating sea breezes along both coasts this afternoon will stay
generally 10 mph or less, and with low level moisture remaining
very shallow, any showers that manage to develop along the sea
breezes will be meager and insignificant.

Temperatures should reach 80 degrees over most areas away from the
coasts this afternoon, with lower 80s over the southern
everglades.

aviation...

vfr will prevail under high pressure. A few mostly light showers
and associated bkn ceilings around 2,500 ft over the near-shore
atlantic waters this morning should have little to no impact on
terminals. Patchy light fog over the interior peninsula will burn
off by 14z. Light wind will turn to seabreezes 8-10 knots along
the atlantic and gulf coasts from about 16z-00z, then back to
light and variable after 00z.

Prev discussion... Issued 232 am est Fri feb 15 2019
discussion...

high pressure governing across the sunshine state, in conjunction
with primarily zonal flow in the mid-levels, will keep conditions
mostly dry for Friday and throughout the weekend. The 15 00z
sounding shows a pwat value of 0.76 inches which falls a hair
below average for this time of year, further supporting a dry and
pleasant day across south florida; however, a shower or two can't
be ruled out completely in the atlantic as Wednesday's cold front
has stalled over the bahamas. Additionally, models are hinting at
a gulf breeze setting up this afternoon, but showers are not
anticipated.

For this morning, high clouds will continue to stream in before
sunrise, limiting radiational cooling. So despite light to calm
winds, the lack of radiational cooling and inadequate low level
moisture will ultimately suppress widespread fog development. Any
fog that does somehow manage to make an appearance (which would be
near the gulf coast and western interior) will stay quite
shallow patchy and short lived. Temperatures today will climb into
the upper 70s to lower 80s, just hovering near seasonal average
for this time of year.

For the remainder of the forecast period, a series of systems
will approach southeastern CONUS but will be unable to conquer us
here in south florida thanks to that fairly persistent high
pressure holding strong over the region. Eventually, rain chances
will return early next week as winds shift from the S SE and low-
level moisture returns. Warming temps and light flow may also
allow the return of sea breeze activity.

Marine...

as high pressure builds back in for the weekend, conditions
should remain below advisory thresholds with weakening winds and
diminishing seas. High pressure will remain around the region
through a good portion of the next week, allowing for pleasant
boating conditions.

Beach forecast... The rip current risk will diminish as the wind
lightens over the next couple of days.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
