Aviation
The winds will remain easterly this afternoon into tonight, as
wind speeds will be between 10 to 15 knots this afternoon
decreasing to 5 to 10 knots tonight. The only exception to this is
at kapf where the wind direction will be westerly this afternoon
before going light and variable tonight. The ceiling and vis will
also remain theVFR conditions through tonight. There could be a
shower or two over northeastern areas of south florida this
afternoon, but the coverage will be few and far between to mention
it in the TAF sites. Therefore, the TAF sites will remain dry
through tonight.

update...

the fog that been occurring over the interior and west coast metro
areas has burned off this morning leaving only some low level
clouds. These low cloud should burn off through the morning hours.

Therefore, the fog wording will be remove from the zones in the
morning update for the interior and west coast metro areas.

High pressure over the western atlantic waters will build into the
florida peninsula tonight into Friday. This will allow for the
wind flow to swing from a southerly direction this afternoon to a
easterly direction tonight into Friday. Both the east and west
coast sea breezes will also develop and push inland today focusing
any showers over the interior areas this afternoon. However, the
coverage will be few and far this afternoon, as drier air has
worked into the area from the south. Therefore, there will only be
silent 10 percent pops over the interior areas for this afternoon
with less than 10 percent over the metro areas.

The winds will remain southeast at 10 to 15 knots over the
atlantic waters today leading to a moderate risk of rip currents
along the east coast beaches of south florida. Rest of south
florida waters will see winds around 10 knots mainly from the
southerly direction.

Rest of the forecast looks good at this time and no other changes
are planned.

easterly winds around 10 mph will increase to around 15 mph over
the east coast TAF sites today, as the ceiling and vis will remain
in theVFR conditions. Kapf TAF site will see light southeast
winds this morning before swinging to an westerly direction this
afternoon around 10 mph. There could still be some fog around at
kapf TAF site through 13z with vis and ceiling dropping down into
ifr conditions. After 13z today the ceiling and vis should be back
intoVFR conditions. The weather will also remain dry over all of
south florida TAF sites today.

convection remains just beyond the coastal waters over the western
bahamas this morning. Outflow boundaries from this convection
could reach towards south florida today, promoting the potential
for some showers. Otherwise, it is expected to be a fairly warm
day with the southeasterly flow push inland from the atlantic and
a gulf sea breeze developing and pushing inland this afternoon.

Expect most of the rain chances to be confined along the east
coast and over the atlantic waters.

Deep layered high pressure builds in on Friday, promoting a drier
day with sunshine and summer-like warmth to kick off the weekend.

The next frontal system will progress across the central united
states late in the weekend and makes its way towards the sunshine
state Monday into Tuesday. There is some difference in timing
between different global guidance. Went ahead and broad-brushed
much of next week's forecast due to this uncertainty in timing.

The front will have plenty of moisture ahead of it to promote
showers and potentially thunderstorms. As of right now, the front
will also pack the ability to have some showers and thunderstorms
along with it.

As the first front exits mid to late next week, the next system
emerges over the region. This could too pack a bit of a punch and
the forecast continues to carry showers and some thunderstorms
through the end of the forecast period. This is still quite a bit
away being late in the extended... So confidence is low and the
different models are providing slightly different solutions as
well. It will be worth monitoring the forecast trend with these
frontal systems over the next week or so.

Marine...

winds and seas should remain below headline criteria heading into
the weekend. Some showers could be possible today with those
chances dropping for tomorrow. During the weekend, the approaching
frontal system will allow winds and seas to build which could
introduce headlines later in the weekend for mariners.

for the east coast TAF sites, light southeast winds will persist
through mid morning. A sct/bkn low cloud deck continues to push
ashore from the atlantic, giving periodic ceilings around 1500 ft
agl to mia and opf. Expect these clouds to shift northward over
the next several hours. South southeast winds will increase aft
27/1400z, generally 12-15 kt, then decrease back to around 10 kt
aft 28/0000z. A gulf sea breezy may develop, bringing southwest
winds to kapf during the afternoon. Otherwise, expect sct low
clouds with bases around 3500 ft agl andVFR conds to prevail
through tonight.

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.
