.DISCUSSION...
Issued at 228 PM EDT Thu May 7 2026

Current-Tonight...Primary weather concern revolves around the record
heat and dry conditions, as well as heightened fire sensitivity. A
surface-based high pressure ridge axis has relocated south/east from
ECFL with the approach of a weak front that will press south into
north-central FL overnight and into central FL early Fri morning.
The location of the ridge axis has allowed for winds to veer to SW/W
with sustained speeds up to 10-15 mph and higher gusts (20-25 mph).
As for the ECSB, it will be delayed and may only develop from near
the Cape southward, with limited movement inland late today. As
such, afternoon temps are forecast to soar into the M90s (nearly
areawide), including the coast, with a few U90s within reach. Daily
max records are forecast to be tied/broken at many of our climate
sites. See Climate section below.

Temperatures remain warm and well above climo (as much as 10
degrees) overnight as moisture slowly deepens with approach of the
aforementioned front. Mins forecast in the U60s to M70s.

With the approaching boundary, cloud ceilings (low stratus) are
forecast to lower after midnight toward sunrise across the I-4
corridor, possibly as far south as Titusville and Melbourne near
daybreak Fri morning. There will be a decaying area of convection
dropping southward overnight, and a few showers may clip portions of
north Lake/north Volusia counties early Fri morning and we have
added a small PoP (15-20%) here to cover for it. Have managed to
keep fog out of the forecast, but we should monitor southern Osceola
thru Okeechobee County for some potential patchy fog here late
overnight/early Fri morning.

Residents and visitors sensitive to heat should take precautions for
these well above normal temperatures. Remember, NEVER leave children
or pets in cars for any period of time. The increasing heat, as well
as dry and gusty conditions today will lead to an elevated fire
weather danger this afternoon and early evening.

Fri-Sun...The weak front will slide south into central FL early Fri
morning, becoming nearly stationary, then lifting back north Fri
night/Sat. Low clouds, near Melbourne northward could be slow to
burn off during the morning. Also, would not be surprised to witness
some light shower activity (1-4 corridor) during the morning.
Moisture does surge ahead/along this boundary and we will see daily
sea breeze formation and collisions across the central FL peninsula
on Fri, and more towards the eastern FL peninsula side Sat/Sun. We
forecast 20-50% PoPs Fri aftn/eve for far north Okeechobee County
toward Melbourne northward. On Sat, 20-40% PoPs forecast from
generally along the Treasure Coast northward in the aftn/eve
(highest Volusia), with far western reaches of ECFL toward the
Kissimmee River & western Lake County left out. For Sun 20-40% PoPs
nearly areawide. Storm steering is out of the west so convection
could move back toward the coast each evening. Lingering dry air
aloft will continue the potential for ISOLD strong (marginally
severe) storms each day, producing frequent lightning strikes, and
gusty winds up to 40-50 mph - perhaps one or two storms to 60 mph,
and small hail. Some storms may also produce locally heavy rainfall
of 1-2 inches in a short-period of time. Another concern will be for
the potential for fire-starts from lightning strikes, esp away from
the main precip core.

Additional cloud-cover and earlier initiation and deeper inland
movement of the sea breeze will limit continued (already) above
normal temps. Generally U80s (coast) to L90s on Fri for maxes,
widespread L90s on Sat/Sun and cannot rule out a few M90s as well.
The above normal temperatures and increasing relative humidity will
produce widespread peak heat indices in the M-U90s (up to 100
degrees locally) and promote HeatRisk categories to Moderate and
locally Major.

Previous Extended Forecast Discussion Modified...

Mon-Wed...Mid/upper level trough moves through the eastern U.S.,
pushing a weakening cold front toward and eventually through the
area early next week. Current projections from model guidance has
this boundary moving through Mon night, with scattered showers and
storms developing ahead of the front Mon and pushing offshore, with
rain chances increasing up to 40-60%. Increasing W/SW winds aloft
may lead to some stronger storm development Mon afternoon, with the
main threats including frequent lightning strikes, strong wind gusts
and locally heavy rainfall. High pressure pushing off the Mid-
Atlantic coast will switch winds quickly onshore behind the front on
Tue, with lingering moisture leading to low end rain chances (20-
40%) mostly along portions of the coast into Tue. Otherwise, mostly
dry conditions are then forecast into the middle of next week.

Increasing cloud cover and rain chances ahead of the front will
lower max temps slightly on Mon, but still forecast near to above
normal in the U80s-L90s. Highs are forecast to drop slightly to more
seasonable values in the 80s behind the front into Tue-Wed.

.MARINE...
Issued at 228 PM EDT Thu May 7 2026

Current-Tonight...The low-level high pressure ridge axis has slipped
south of the local waters as a weak front approaches late tonight
and early Fri. Generally southerly winds 10-15 kts becoming more SE
along the immediate coast this aftn as the sea breeze develops but
remains fairly close to the coast.  Models hint at a brief wind
surge offshore late today into tonight 15-20 kts before backing down
to 10-15 kts late as winds veer west, then WNW ahead of daybreak.
Generally dry conditions continue with seas 2-3 ft.

Fri-Mon...The weak front may slip into our northern waters early Fri
morning, possibly as far south as the Cape and cannot rule out ISOLD
showers with it. This feature will become nearly stationary,
briefly, before lifting back north Fri night/Sat. Sea breeze
collisions over the peninsula each day may send convection
(ISOLD/SCT) back toward the coast each evening, esp Cape northward
as moisture surges across the region in association with the front.
A few strong storms will be possible.

Otherwise, boating conditions continue to be mostly favorable. There
will be some variability in the winds thru the remainder of the
extended with onshore flow each aftn with the sea breeze, then some
offshore potential each night. Any convection will temporarily alter
wind fields from time to time. Wind speeds generally 10-15 knots,
but may increase to 15-20 knots offshore briefly during the late
afternoon/evening hours, again, on Sat/Sun. Seas typically 2-3 ft
but could build to 4 ft surrounding wind surges and may be
locally higher invof showers/storms.

Another weak front is forecast to push southward through the waters
into early next week, with SCT showers and storms (some strong)
developing ahead of the front and pushing offshore. Winds are
forecast to become SW Mon at 10-15 knots (pre-frontal), then N/NW
Mon night (post-frontal). Seas continue 2-4 ft.

.AVIATION...
(06Z TAFs)
Issued at 210 AM EDT Fri May 8 2026

Mainly VFR with intermittent MVFR CIGs as a front approaches from
the north. Latest satellite and ground observations indicate
SCT/BKN 018-025 moving south toward LEE/SFB/DAB. CIGs may drop to
MVFR at times, perhaps reaching MCO before 14z. Some improvement
is expected thereafter, prior to SHRA/TSRA development after
16z-18z. VCSH/TS and TEMPOs were included from MCO northward (may
need to add TIX in later updates), with a primary focus for TSRA
impacts after 20z. Activity gradually dissipates after 03z while
moving offshore.

West winds shift NW/NE by 18z, then onshore (ENE) as the sea
breeze develops, remaining 8-12 kt. Winds become light and
variable into early Sat.

.FIRE WEATHER...
Issued at 228 PM EDT Thu May 7 2026

Sensitive to critical fire weather conditions will exist this
afternoon and early evening as record highs in the mid 90s and dry
conditions produce Min RH values as low as the upper 20s to mid 30s
for much of the area. A Red Flag Warning remains in effect from
Osceola and Brevard counties northward where critically low RH and
gusty west to southwest winds around 15 mph are forecast to
coincide. While near to critically low RH is also forecast farther
south, wind speeds are forecast to remain just below 15 mph. This
will still lead to sensitive fire weather conditions across
Okeechobee County and the Treasure Coast. The east coast sea breeze
will likely form near to south of the Cape with limited inland
movement, but will be delayed, switching winds to the southeast.
This will keep Min RH values just above critical values along the
immediate coast where the sea breeze is able to form. Dispersion
will be Very Good to Excellent this afternoon, which may lead to
control issues. Dispersion will fall back to Fair to Generally Good
on Friday and Very Good to Excellent again on Saturday.

A weak front pushes into the north central Florida on Friday before
lifting northward into the weekend. This will increase moisture,
keeping RH values above critical values, but will also help generate
isolated to scattered lightning storms, mainly during the afternoon
and evening hours from late week into this weekend and early next
week. A few storms could be strong to marginally severe. However,
there could be some light rain showers early Friday morning north of
I-4 in association with the boundary.

Also, low stratus clouds are forecast to be associated with the
front and dip as far south as Melbourne, with a slow burn-off of
these low clouds Friday morning. Widespread fog is not forecast.
However, we should monitor southern Osceola thru Okeechobee County
for some potential patchy fog here late overnight/early Fri morning.
