Area Forecast Discussion
National Weather Service Melbourne FL
329 AM EST Sat Feb 24 2018

.DISCUSSION...
Currently...Fog development will continue to be possible through
early this morning near to northwest of the I-4 corridor.
Observations are indicating visibilities have already begun dropping
from Sanford to Daytona, but latest traffic camera imagery near these
sites doesn`t indicate much more than shallow patchy ground fog. Fog
could thicken some toward daybreak over these areas, but with
elevated SE boundary layer winds across the region, greatest
potential for any dense fog looks to remain north of Lake and
Volusia counties. Will therefore leave mention limited to patchy fog
for northern portions of east central Florida in the forecast.

Today-Tonight...Ridge axis of high pressure over the west Atlantic
that is currently north of the area will begin to shift southward
and eventually settle across the area into tonight. This will veer
low level southeast winds to the south-southwest into tonight. Low
level moisture will build northward across the area through the
afternoon in this flow, with PW values increasing slightly today.
This should again lead to shower development along and ahead of the
inland moving east coast sea breeze, but coverage should remain
isolated with strong ridge aloft. Highs will continue to range from
the low 80s along the coast to mid 80s over the interior, with lows
in the mid to upper 60s tonight.

SUN-MON...Regional upr ridge responsible for the extended period
of well above normal temperatures will become slowly elongated and
weakening through Sunday in response to mid level impulses moving
across the lwr MS valley. Veering winds combined with reduced
subsidence will lead to isold rain chcs primarily at the coast
Sunday then all areas by Mon aftn. Temp ranges will remain well
above normal as well. A slow moving frontal boundary is advertised
to progress into N FL by late Monday.

TUE-FRI...Ongoing migration of pattern to zonal aloft with a
weakening surface front moving across central FL on Tue. Ascd
moisture looks marginal at best to produce no more than isold rain
chc due to lack of forcing mechanism. Temps wl remain at to above
normal to close out the month. Broad ridging is shown trying to
re- establish over the state from mid to late week with continued
rather dry and warm conditions to begin the month of March. A more
pronounced front may make it south into the area around Friday,
bringing cooler conditions for the weekend.

&&

.AVIATION...Patchy ground fog will continue to produce varying
visibilities to IFR/MVFR near to northwest of the I-4 corridor
through early this morning. Otherwise conditions will predominantly
be VFR across the area today, with only brief reductions to MVFR in
any isolated showers that develop along and inland of the east coast
sea breeze through the day.

&&

.MARINE...
Today-Tonight...Ridge axis north of the waters will gradually shift
southward and across the region into tonight.  This will veer
southeast flow to a more southerly direction past sunset, with wind
speeds remaining around 10-15 knots. Longer period swells will
decrease slightly into today, with seas ranging from 3-5 feet.

SUN...Open water conditions wl remain marginally favorable. No
headlines are anticipated, however SE-S winds breezy at times in
the afternoon along the coast combined with remnant swell will
produce 3-5 ft seas over the open waters with highest seas well
away from the coast.

MON-THU...Weakness created by surface boundary over N to central FL
will bring lighter winds to the local marine area early in the
week with veering to S to SW component on Monday. A modest wind
shift to N-NE on Tue will veer direct onshore into midweek.
Headlines are not anticipated at least the first half of the week.

.CLIMATE...Melbourne and Vero Beach still have a shot at breaking or
tying their record warm low for today, February 24th. An additional
warm minimum temperature record or two could be possible on Sunday,
February 25th, mainly for coastal sites.

                    February 24     February 25

Daytona Beach         68-1962         66-1928

Vero Beach            71-1962         70-2001
Ft. Pierce            70-1949         69-2001

Temperatures still forecast to remain well above normal through the
remainder of the month, and a record warm February looks on track
for Orlando, Melbourne, Sanford and Vero Beach, with Daytona Beach
and Fort Pierce likely coming in second warmest.
