.KEY MESSAGES...
Issued at 300 PM EDT Fri Oct 9 2026

- A High Risk of life-threatening rip currents continues at all
  Central Florida Atlantic beaches today. Stay out of the rough
  surf!

- Scattered to numerous (~ 50-80%) showers and lightning storms
  are forecast each day through the weekend with coverage peaking
  in the afternoon and early evening. The strongest storms will be
  capable of producing gusty winds of 40-50 mph and occasional to
  frequent lightning. Locations that see repeated storms will have
  the potential to experience localized flooding

- Remaining quite warm and very humid through Sunday, with peak
  heat index values as high as 100 to 105 degrees. Know the signs
  of heat illness; take frequent hydration breaks in the shade or
  A/C. Less humid conditions are forecast by Monday

.DISCUSSION...
Issued at 300 PM EDT Fri Oct 9 2026

Currently-Tonight... KMLB radar imagery currently shows dry
weather across east central Florida. GOES-19 satellite imagery and
local observations indicate partly to mostly cloudy skies across
east central Florida. Temperatures are currently in the mid 80s to
low 90s with dew points in the mid 70s to around 80 degrees. Winds
are breezy from the southeast at 10-15 mph with gusts to 20-28mph.
The 10Z XMR sounding showed MLCAPE at 1,327 J/kg, 0-6km shear at
31kts, a PWAT value at 2.11," and a 500mb temperature at -6.4C.
Analysis charts show the Atlantic ridge extended over the Florida
Panhandle with Major Hurricane Isaias moving north-northeast at
16mph near the Alabama coast.

Scattered to numerous (~30-70% chance) generally north-northeast
moving showers and lightning storms are forecast this afternoon and
evening before chances gradually diminish around 8PM. Guidance
shows MLCAPE increasing to up to 2,500 J/kg, 0-6km shear up to
35kts, a LLJ up to 25-30kts across northern ECFL, and PWAT values
up to around 2.3-2.5" (90th percentile to the maximum percentile
for the date). The aforementioned weather parameters are
sufficient for isolated strong storms capable of occasional to
frequent lighting, wind gusts up to 35-45mph, and heavy rainfall
(up to 1-2" in 60minutes). Expect breezy southeast winds to
gradually weaken tonight at around 5-10mph. Above normal (~4F-8F
degrees) low temperatures in the low to upper 70s are expected.

The Weekend... The wet weather pattern is expected to continue
through the weekend as Major Hurricane Isaias transitions to a
extratropical system with a cold front - extending from the low
over central Tennessee - across east central Florida on Sunday.
Rain chances (~50-80% chance) will remain high through the weekend
with scattered to numerous showers and lightning storms expected
each afternoon and evening hours. However, the coverage of showers
and lightning storms will be nearly equal across all of east
central Florida on Saturday; then the coverage will be greatest across
areas to the south of I-4 on Sunday as the aforementioned cold
front moves south-southeast across east central Florida. Guidance
shows moderate instability, moderate bulk shear values, relatively
warm 500mb temperatures at -5C to -6C, and PWAT values up to
2.3-2.5" (90th percentile to the maximum percentile
for the date). Thus, the primary hazards with isolated strong
storms will be occasional to frequent lightning, wind gusts up to
40-50mph, and heavy rainfall (up to 1-3"+ in 60 minutes).
Additionally, there is a Marginal Risk (level 1 out of 5) for
excessive rainfall on Saturday.


Monday-Thursday... Deterministic models and LREF-clusters are in
good agreement that the Atlantic ridge will weaken and shift east
over the western Atlantic as a longwave trough deepens over the
eastern CONUS/western Atlantic Monday into Tuesday. The
aforementioned guidance then shows a mid/upper level ridge
building over the eastern CONUS on Thursday; although there is
disagreement on how far north the ridge builds and for how long it
stays over the eastern CONUS. Much drier air filters in across
east central Florida with mostly dry conditions across the region
through Thursday. However, isolated showers cannot be ruled out
across the Treasure Coast Monday and Thursday. Expect offshore
flow through Tuesday before flow shifts onshore
midweek. Seasonable high temperatures are forecast with seasonable
to above normal low temperatures.

.MARINE...
Issued at 300 PM EDT Fri Oct 9 2026

Currently-Tonight... Poor and choppy boating conditions are
expected even outside of showers and lightning storms. Isolated to
numerous generally offshore moving showers and lightning storms
are forecast. The potential exists for isolated strong storms
capable of wind gusts at 34kts or greater. Southeast winds are
expected to increase tonight at 15-20kts with gusts to 25kts.
Seas up to 2-4ft with up tp 5ft over the Volusia county waters are
forecast. Small Craft Should Exercise Caution.


Saturday-Tuesday (modified previous discussion)... Moderate winds
on Saturday are expected to become southerly on Sunday. Small
craft should exercise caution at times, particularly on Saturday.
Scattered to numerous showers and storms will continue through the
weekend. The potential exists for isolated strong storms capable
of wind gusts to 34kts or greater. A front arrives on Monday
which will usher in drier air next week. SE winds at 10-15 kts
increase to 15-20 kts on Saturday. Winds turn southerly on Sunday
at 10-15 kts. Seas generally 3 to 4 feet through this weekend. A
front will turn winds northwesterly on Monday with seas remaining
3 to 4 feet.

.AVIATION...
(18Z TAFs)
Issued at 127 PM EDT Fri Oct 9 2026

A weak frontal boundary has lifted just north of KDAB/KLEE early
this afternoon promoting ESE/SE winds (7-12 kts - few higher
gusts) areawide. However, deep moisture remains across the area
and expect a summer diurnal SCT-NMRS shower/lightning storm
pattern with activity lifting northward. Highest PoPs inland and
along/north of I-4. Inherited "Vicinity", "PROB30", and "TEMPO"
wording for many TAF sites this aftn/early eve. Still dealing
with some spotty MVFR CIGs, otherwise generally VFR outside of
convection. Showers/storms diminish thru this evening with mainly
dry conditions overnight. Winds light SE/ESE.

For Sat, S/SSW winds which may "back" SE along the immediate coast
in the aftn with sea breeze development, but push inland limited.
Higher than normal shower/storm chances continue (60-80%) and mainly
afternoon/evening variety.
