Discussion
Current... Water vapor imagery shows very dry air aloft across the
region early this morning with mid level shortwave ridging over the
gomex. Weak surface high pressure ridging remains across the area
with associated weak pressure gradient. Mclear skies early on with
mild temperatures in the 60s, light winds and conditions dry. Will
need to watch for any patchy fog formation or smoke issues near
sunrise, especially around any smoldering burns.

Today-tonight... The influence of surface high pressure ridging and
light winds will linger around for another day. Shortwave ridging
aloft will move across the fl peninsula this afternoon providing
subsidence, then moving out into the western altc this evening.

Light/variable morning winds will become onshore along the east
coast late morning/early afternoon, then this trend will track
inland through the interior over the remainder of the afternoon and
early evening. Expect an evening collision of both east/west sea
breeze boundaries west of orlando, but moisture/instability still
not impressive to ignite any convection and will leave conditions
dry over the next 24hrs. A boundary over the deep south will slide a
bit further southward into late tonight, but still remain well north
of our coverage warning area.

Continued warm with afternoon highs generally in the l80s along the
coast and m-u80s inland. Overnight lows continue mild and mainly in
the 60s with some u50s possible well inland from the treasure coast
and over okeechobee county. Winds become light/calm again tonight.

The lighter winds and mclear skies will again produce the potential
for shallow, patchy fog overnight. Main concern will be if any smoke
from lingering brush fires mixes with fog and leads to localized
reduced visibilities on some roadways late tonight into early
morning thu.

Thu-fri... Unseasonably warm conditions Thu ascd with proximity of
high pressure and SE flow will produce aftn temperatures well into
the 80s with mild night time temperatures in the l-m60s thu
night. An approaching disturbance during Fri will improve rain
chcs during the morning and into afternoon with later day timing
of the approaching feature to bring scattered showers and
some developing lightning storms to the area. The relatively fast
moving feature should cross to the atlc waters by fri
night... Ending pcpn chcs for land areas in the evening. A notable
change in airmass is not expected due to lack of frontal psg ascd
with the disturbance.

Weekend... A transitory ridge will become established over the
area with pleasant but warm temperatures expected and scattered
cloudiness at most. Onshore breezes will develop along the coast
each afternoon... Breezy at times due to the seasonally strong
thermal contrast in the coastal zone. Highs in the m-u80s inland
with overnight lows 60-65.

Extended... Another disturbance is shown apchg the area during mon.

This feature initially looks a little more defined than the
previous one, and a window for development of sct storms should
exist at least over the northern portion of the peninsula late
Monday and into tue. As ul energy driving the system pulls away
from the area, a lingering boundary sagging into the central
peninsula tue-wed may help in local pcpn development diurnally.

Sct rain coverage is indicated for the period ATTM through tue
then becoming isold at midweek.

Aviation
Continued mainlyVFR thru the period. Will monitor early
this morning for shallow, patchy fog producing MVFR vsby's for a
brief time. Locally reduced visibilities will again be possible near
any wildfires. Light/variable winds early on. The ecsb will develop
and move inland slowly this afternoon/early evening gradually
backing winds to ese. Winds again l/v this evening/overnight.

Marine Today-tonight... Surface high pressure ridging remains in
control of weather conditions across ecfl. Offshore light winds
early this morning will become onshore along the coast by early
afternoon as the ecsb develops and moves inland. Winds speeds
generally AOB 10 kts over the open atlc thru the period. Wind
direction will become offshore again later this evening and
overnight with the weak pressure gradient in place. Seas 2-4 ft near
shore and 3-5 ft offshore subsiding to 2-3 ft near shore and 3-4 ft
offshore tonight. Persistent east swells could produce rough
conditions near inlets during the outgoing tide again today.

Later week... Stronger sly-se flow 15 to 20 kts ascd with apchg
disturbance will produce increasing seas, ESP over the outer
waters Thu night and into fri. Caution stmts may be required by
late Thu into fri. Improving conds during the weekend ascd with
high nearby should allow for favorable boating conds into sun
eve.

Fire weather High pressure in control of weather with a weak
pressure gradient in place. Light/variable winds slowly backing
toward ese inland from the coast this afternoon/early evening as the
ecsb slowly advances into the interior. Dispersion remains poor to
fair at best. Lowest min rh values this afternoon will be found well
inland (30-35pct) for a few hours. Localized vsby issues for a brief
time early this morning where shallow, patchy fog mixes with smoke
from any ongoing smoldering burns.
