Aviation
The winds will be from the southerly direction tonight with speeds
between 5 to 10 mph over all of the TAF sites before going
southwest on Friday with speed increasing to around 15 knots
ahead of a cold front. The front should be mostly a dry front on
Friday, except for some showers around kapf TAF site. The ceiling
and vis should remain inVFR conditions through Friday.

Update
Main change is to add a slight chance of showers for portions of
the atlantic coast and kept higher winds into the overnight hours.

Otherwise, little change to the forecast.

discussion...

weakening surface high pressure to the east has kept today's
weather mostly dry with near normal temperatures across the
region. To the northwest, an upper-level trough is chugging across
the lower mississippi river valley with an associated surface low
pressure area and attendant cold front stretching southward into
the west central gulf of mexico. As the evening and overnight
hours progress, the system will continue its eastward voyage
towards the florida peninsula, increasing the thunderstorm and
shower chances along with the pressure gradient. A breezy day is
in store for Friday due to the tighter pressure gradient which
will may possibly provide advisory level conditions across the
atlantic waters and cautionary conditions across lake okeechobee... More
in marine section below...

the main story here is what the storm prediction center is saying.

Previously, a good chunk of south florida was under a "marginal"
risk for severe storms Friday; now, that risk has been pulled
northwards with only the far NW portion of glades county in the
"marginal" risk. Otherwise, pretty much all of south florida is
now in a general thunderstorm risk, moreso along the waters and
lake okeechobee region. As the front traverses the state from nw
to SE on Friday, the stronger and more supportive dynamics rest
across central northern florida. Regardless, there is still a
chance for isolated thunderstorms across the region tomorrow.

Friday night into Saturday looks even more unfavorable for
thunderstorm development across the peninsula as dry air begins
to filter in and the environment becomes increasingly hostile for
thunderstorm development.

Entering the weekend, guidance continues to hone in on drier air
filtering southward into south florida. This will lead for a
generally mostly dry weekend. Some showers, fed by atlantic and
gulf moisture, cannot be ruled out especially if any sea breezes
were able to get going on Saturday or Sunday (which it looks like
they will). Temperature wise, no impact from the cold front
whatsoever... High temps are still forecast to be in the low to mid
80s areawide.

By early next week, high pressure will build back towards the
area from the atlantic which will allow for persistent easterly
flow to return through the rest of the forecast period. GFS and
ecmwf do differ a bit in the amount of available moisture heading
into mid-week next week. Favored a blend between the two models
for pops for the time being due to low confidence.

Marine...

se winds are forecast to veer and increase from the SW tonight
into Friday morning as a cold front approaches the region. Then,
Friday night into Saturday morning, winds will veer from the W nw
after frontal passage. For the time being, small craft should
exercise caution across the offshore atlantic waters and lake
okeechobee throughout the day tomorrow. Advisory criteria might be
met for the offshore waters, but will monitor overnight to see if
that is the case.

Increasing chance for showers and thunderstorms Friday into parts
of the weekend, particularly for the atlantic waters. By next
week, a persistent easterly flow returns with the potential for
increasing winds and waves.

Beach forecast...

as a cold front approaches the region Friday, an elevated risk of
rip currents could develop briefly along the palm beach county
beaches due to a northeasterly swell. That risk should stick
around for the couple of days before further increasing early
next week as easterly winds return. This return in easterly wind
flow will also increase the rip current threat for the rest of
the atlantic beaches by early next week.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
