Synopsis..Moderate southeasterly flow will continue across all the waters today, veering south-southwesterly on Sunday ahead of a cold front that is forecasted to push through our area late Sunday into Monday. A strong east-northeasterly wind surge behind the front will bring the potential for hazardous boating conditions, especially over the atlantic, late Monday into Tuesday. Coverage of showers will increase into early next week with the front.

Update
Ridge of high pressure over the western atlantic waters will
remain nearly stationary through today keeping an southeasterly
wind flow in place over south florida. The east and west coast sea
breezes will also develop and push inland with the east coast sea
breeze being the main sea breeze. Therefore, the isolated showers
over the atlantic waters should slowly dissipate through the
morning hours, but one or two of the showers could still work into
the east coast metro areas this morning before the showers
dissipate. Therefore, kept the slight chance of showers in the
forecast for the east coast metro areas through the morning hours.

Isolated showers are also possible this afternoon especially
over the western interior areas late this afternoon into the early
evening hours where the east and west coast sea breeze collide.

Therefore, a slight chance of showers have been added for these
areas for this afternoon into the early evening hours.

Highs today should warm up to into the mid 80s over the east coast
metro areas to the upper 80s to around 90 degrees over the
interior and west coast metro areas. The high temperatures over
the interior and west coast metro areas will be close to the
record highs for this time of year, and naples could tied the
record high temperature for today which is 87 degrees set back in
2018.

The high risk of rip currents will also continue for the east
coast beaches of south florida today, due to the easterly winds
and low tide late this afternoon.

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

vfr conditions are expected to prevail through the
period. Isolated showers will be possible, but overall coverage is
expected to be pretty low. Otherwise, SE flow continues through
tonight with winds becoming a little gusty in the afternoon
today. Winds begin to shift more to the S tomorrow.

Prev discussion... Issued 406 am est Sat feb 23 2019
discussion...

today and tonight: today will be similar to the past few days as we
remain under the influence of the large mid and upper level ridge
just to our southeast with the low level ridge axis just to our
north. Patchy morning fog across the interior will give way to
another partly sunny and very warm day. Highs will remain in the mid
to upper 80s, or just below records.

Prevailing breezy southeasterly flow will bring morning showers
across the atlantic and east coast, with the focus shifting across
the interior into the afternoon hours. Modest seabreeze collision
will lead to a few more showers just inland from the gulf coast
late in the day, but coverage is expected to remain isolated at
best.

Overnight lows remain warm and muggy in the upper 60s and 70s,
with a few late night showers moving through as flow veers out of
the south-southwest. Patchy interior fog will be a concern again
tonight.

Sunday and Monday: the mid-upper level ridge that has been driving
our weather for the past week will slide further southeast and
weaken enough to allow a frontal boundary to progress south into
the region by Monday.

Overall moisture is expected to remain low on Sunday ahead of the
boundary, but enough to squeeze out a few showers along the
seabreezes. With the ridge axis suppressed south of the region,
prevailing south-southwest flow will push the gulf breeze across
the peninsula and focus more scattered showers towards the
atlantic coast later in the day. Sunday will likely be the last
well above normal day, still in the mid to upper 80s across the
region. Temps currently look to remain just below record highs,
but if the atlantic seabreeze or any showers develop later, temps
may approach the record values of 88-89f along the east coast.

The front itself will drop into the region late Sunday night,
gradually sinking south of the region early on Monday. Mid level
flow will quickly become zonal, with low level flow already expected
to come around to the east-northeast by midday. This highlights the
diminishing lift aspects of the front, though the lingering moisture
boundary will be enough for widely scattered showers along wherever
the front ends up during the day.

Remainder of the week: fairly zonal slight troughing pattern will be
in place across the region in the mid-levels into mid week. With no
significant mid-level push, the frontal boundary will halt its
southward progress across the florida straits on Tuesday. Best
rain chances for the week, along with the potential for a few
storms will be as the boundary slowly lifts back across the region
on Tuesday.

Beyond Wednesday, the GFS and ECMWF differ considerably in exactly
where the front ends up as it moves north of the areas. Both show
the potential for a late week vort MAX shortwave to move through,
kicking off some degree of cyclogenesis along the boundary.

However, the exact timing and nature of this is still very much
unclear given the vast model differences. Model consensus suggests
a continuing moist pattern with a chance of showers each day to
end the week.

Marine... Moderate southeasterly flow will continue across all the
waters today, veering south-southwesterly on Sunday ahead of a
cold front that is forecasted to push through our area late Sunday
into Monday.

A strong east-northeast wind surge is expected behind the front
into Monday afternoon as the front stalls across the florida
straits, with the gusty winds continuing into Tuesday. Conditions
may approach advisory levels as winds across the atlantic approach
20 knots with 15-20kts over the gulf. Seas may build to 6-7ft in
the atlantic through midweek.

Winds subside and become south-southeasterly into Wednesday as the
boundary lifts back to the north.

Beach forecast... The high risk for rip currents continues along
the atlantic beaches today under continuing breezy southeasterly
flow. Veering winds will limit the threat along the atlantic
beaches to start the week, with a high risk likely returning
behind the front into mid week with stronger east-northeast winds.
