.DISCUSSION...

Current-Today...Weak front currently pushing southward across the I-
4 corridor. The low clouds (stratus) over this area continue to
slowly lift/burn off as the sun rises and drier air slowly slides
down the peninsula behind the front. Further south across southern
Okeechobee, southern St. Lucie, and Martin counties, KMLB Nexrad 88D
shows showers with embedded lightning streaming west to east and out
across the adjacent coastal waters. Some heavy downpours and perhaps
gusty winds, too, as these training echoes could gradually amount to
1.00 to 1.50 inches across portions of Martin County. Much of this
activity is the result of ample moisture and energy traversing the
area. As the front continues southward this trend will diminish and
push south of Martin County into early afternoon. For the morning
update will likely begin to trim back PoPs (north to south) as the
aforementioned boundary passes through. SW/W winds will veer NW
behind the front with speeds increasing to 7-12 mph over the
interior and in upwards of 15 mph along the coast. Wind speeds could
be immediately a bit higher for a short time post-frontal. Winds
closer to the coast will continue to veer to N/NNE/NE/ENE thru late
aftn/early evening. Thinning skies overall will gradually occur post-
frontal from north to south as high pressure slowly builds in from
the northwest.

High temperatures will reach the upper 70s to low 80s at the coast
and mid 80s across the interior, but it should start to feel quite
comfortable out as the airmass steadily dries out.

Tonight...Previous...High pressure will continue to build over the
SE U.S. and FL overnight. As the pressure gradient relaxes winds
will become light, and combined with dry air and mostly clear skies,
a cool night is expected with temperatures dropping fairly quickly
after sunset this evening. Overnight lows in the mid-upper 50s for
most but a few normally cooler spots could see some lower 50s.

&&

.AVIATION...Stubborn stratus to continue to burn off into mid-late
morning. Cold front currently pushing south of I-4 will pull in
drier air with MSunny conditions gradually spreading from north to
south across ECFL. Showery precip (ISOLD TSRA) southward, generally
south of KFPR will gradually get pushed south of KSUA into early
afternoon as the front continues down the peninsula. VFR conds
areawide by early afternoon and continuing thru tonight.

&&

.MARINE...Today...A cold front will push across the waters early
today. Shower and isolated lightning storm activity will occur ahead
of the front into early afternoon and generally south of Ft. Pierce.
Westerly winds 10-15 knots with some higher gusts will veer to the
NW behind the front and then N/NE this afternoon. Seas 2-3 ft near
shore and 3-5 ft Gulf Stream.

Tonight...Previous...High pressure will continue to build across the
southeast U.S. with the ridge axis draped across Florida. Winds will
become offshore around 10 kt roughly north of Sebastian Inlet
overnight while remaining NE at around 10 kt to the south. Seas will
gradually subside to 2-3 ft except 3-4 ft in the Gulf Stream.

&&

.FIRE WEATHER...Today...Previous...Much drier air will quickly move
into the area behind a cold front from north to south beginning late
this morning and continue the rest of the day. Min RH expected to
fall into the low-mid 30s over portions of the interior late this
afternoon, possibly reaching the upper 20s to the north and west of
I-4.
