Winds will become westerly as the front exits our area and gradually decrease in the late afternoon. However, poor to hazardous boating conditions will remain through Monday as moderate to fresh northerly winds occur behind the front. Winds and seas will slowly subside this weekend, but remain choppy in persistent north to northeast flow.
Gulf stream hazards..South to southwest winds increasing up to 25 to 30 knots, with frequent gusts to gale force through the morning. Seas building up to 8 to 10 feet.

Discussion
Marginal risk of strong to severe thunderstorms across east
central florida this morning...

Hazardous sea conditions through this afternoon...

today-tonight... A cold front extending from the NE u.S. Towards
central fl panhandle early this morning will continue to push to the
southeast today. At the same time, an area of high pressure will be
pushed east and away from the peninsula, keeping a tight pressure
gradient over east central fl today. Active weather (showers and
thunderstorms) will reach the northern counties of our forecast area
(ie lake and volusia) at around 5 am, although a few showers and
storms could develop ahead of the main line. At the mid and upper
levels, a strong jet will lift north at the morning progresses,
remaining to our north. However, south winds of +50 kts were
observed in the last 3 hours at around 2500-5000 ft in the 915 mhz
profiler winds at the cape. These storms will be capable of
producing gusty winds of 30 to 40 mph or higher and heavy rain.

By early afternoon, the front will be over the CAPE and with showers
and perhaps a few thunderstorms reaching the treasure coast. As the
line clears east central fl, weather conditions will improve from
north to south, with temperatures ranging from near 70 for
orange northern brevard north, while the rest of the forecast area
will be able to rise to the mid to upper 70s. A moderate risk of rip
currents is expected today for the east central fl beaches.

By evening night, lingering clouds and perhaps a few showers are
possible for the treasure coast while the rest of east central fl,
will be clearing with northwest winds decreasing. Cold advection
will then be possible, dropping temps to the low to mid 40s north of
i-4, with mid to upper 40s for the space and treasure coast.

Friday-Sunday... After clearing the SE cwa, the cold front will stall
near the florida straits late Friday as its orientation becomes
parallel to the mid level flow. Additional shortwave troughs in both
the northern and southern streams will drop SE into the longer wave
trough over the central-eastern CONUS through this weekend. The two
systems will remain unphased, as the northern trough the lower ms
valley gulf coast deep south, while the southern stream feature
moves across old mexico and the southern gomex. The lack of phasing
will result in multiple frontal waves sliding eastward along the
stalled boundary and remaining south of ecfl rather than a stronger,
more coherent storm system directly impacting the area. This in turn
will make for a cool, damp stretch of weather. Overrunning high mid
clouds will become increasingly widespread this weekend, steadily
lowering, and producing increasing coverage of stratiform rainfall,
especially for the southern cwa. Overall QPF doesn't look terribly
high for this event, and the rainfall is needed given the ongoing
lack of significant rainfall for most areas. MAX temps will stay
well below normal (u50s far north, 60s to the south), with mins in
the 40s and l50s in a cool, damp and occasionally breezy n-ne flow.

Monday-Thursday... The southern stream trough will cross florida
early Monday, and move well offshore Monday night, bringing and end
to the high rain chances by sunset Monday. Long wave troughing will
remain anchored over the central and eastern conus, however, with
multiple weak impulses coming in behind this feature through much of
next week. Consequently, the weak post frontal "bubble" high Monday
night-Tuesday will only provide brief drying decrease in clouds.

Clouds will start to spread back into the area starting late Tuesday
afternoon ahead of the next fast moving cold front, which will move
into central florida late Tuesday night-Wednesday. This front will
be moisture starved as return s-sw flow ahead of is forecast to be
pretty much non-existent. Early indications are this front may get
hung up over south or even central florida through late week as a
breezy showery onshore flow develops. Cooler than normal temps will
continue with only Tuesday looking line and chance for much in the
way of limited Sun and temps to reach the l70s. While there will be
more clouds than Sun much of next week, rain chances from Tuesday
onward look to be fairly low.

Aviation Low CIGS and gusty winds will continue this
morning ahead of a cold front. Shra tsra will move into the area,
starting with klee and continue to the southeast this morning. Gusts
of 30-40 kts, low visibilities and even brief ifr CIGS will
accompany this activity. Conditions should improve after 24 15z from
the NW and clear kvrb-ksua by mid afternoon.

Marine
Today-tonight... Fresh to strong south to southwest breezes this
morning will turn from the west in the afternoon over the east
central fl waters. Due to the offshore flow, seas near the coast
will remain low but by 18 nm east of the coast, seas will be 7 feet
or higher and near 9 ft along the gulf stream. Winds beyond the 20
nm will be near gale with frequent gale force winds gusts. And a
gale warning is in effect for the offshore waters through the
afternoon. As the front moves away, pressure gradient will relax and
winds are expected to drop quickly in the afternoon and early
evening. However, seas will take a bit longer to drop below advisory
criteria until late evening. Boaters should remain in port today as
hazardous seas could get even worse near thunderstorms moving to the
northeast from the coast.

Friday-Monday... Boating conditions will remain less than optimal
through early next week. Post frontal northerly surge will result in
winds seas briefly flirting with 20kt 7ft over the gulf stream early
Friday, with gradual slackening thereafter. A steady, moderate NE to
north breeze will prevail this weekend with seas mainly in the 4-5ft
range. Seas will rebuild Monday as n-ne flow freshens north of the
next frontal wave to our south.

Fire weather Rh values will drop to 30-35 percent over much of
the area in post-frontal northerly flow of 10-12kt Friday. Fire wx
sensitivity should be mitigated somewhat by today's rainfall. Beyond
that, no critical wind rh concerns are expected.
