.KEY MESSAGES...
Issued at 300 AM EDT Sat Oct 3 2026

- There is a High Risk for rip currents through the weekend.
  Entering the surf is not advised! Boating conditions deteriorate
  into the middle of next week

- Scattered to numerous showers and storms are forecast each day
  across east central Florida through this weekend before rain
  chances increase into next week. Minor flooding is the main
  hazard (especially during the workweek) along with lightning
  strikes and gusty winds

- Near to slightly above normal temperatures are anticipated to
  continue across east central Florida through this weekend. Peak
  heat indices nearing and even exceeding 100F are expected

.DISCUSSION...
Issued at 300 AM EDT Sat Oct 3 2026

Currently-Today... KMLB radar imagery currently shows scattered
showers with embedded lightning. GOES-19 satellite imagery and
local observations indicate partly to mostly cloudy skies across
east central Florida. Temperatures are currently in the mid 70s to
low 80s and dew points in the mid 70s to around 80F degrees.
Analysis charts show a mid/upper level high (591mb) over the
southwest Atlantic.

Rain chances (30-60% chance) increase into the afternoon/evening
hours (highest rain chances between 2 PM and 8PM) with onshore low
level flow in place coupled with daytime heating. Guidance shows
MLCAPE up to 1,500-3,200 J/kg, 0-6km shear up to 5-20kts, PWAT
values up to 2.0-2.4", and 500mb temperatures at -6C. Relatively
warm temperatures at 500mb and cloud cover is likely to limit the
strong storm potential, however there is the potential for a strong
storm or two capable of occasional to frequent lighting, wind
gusts up to 35-45mph, as well as heavy rainfall (up to 1-3" in 60
minutes). Afternoon highs in the mid 80s to around 90F degrees are
expected with heat index values up to 98F-105F degrees. There is
a Moderate HeatRisk which affects anyone sensitive to heat without
adequate cooling and hydration. Remember to practice heat safety
if you are sensitive to heat!

Sunday-Monday...  A similar forecast is expected to end the weekend
with onshore low level flow in place. Rain chances then increase
across east central Florida on Monday as a cold front moves
southeast across the Deep South and northern Florida. Expect
isolated to numerous showers and lightning storms to develop on
Sunday with the highest rain chances in the afternoon and evening
(mainly between 2PM-8PM). Scattered to widespread showers and
lightning storms are forecast on Monday with the highest rain
chances (60-80%) in the afternoon and evening hours. Guidance
continues to show a limited potential for strong storms with 500mb
temperatures at around -5C to -4C and moderate MUCAPE values.
Thus, the primary hazards with isolated strong storms will be
occasional to frequent lightning, wind gusts up to 35-45mph, and
heavy rainfall (up to 1-3"+ in 60 minutes). Additionally, the WPC
has outlooked northern east central Florida on Monday in a
Marginal Risk (level 1 out 5) for excessive rainfall. Expect
afternoon highs in the upper 80s to low 90s with heat index values
up to 98F to 105F degrees.

Tuesday-Friday... Deterministic models and LREF-clusters are in
good agreement that a longwave trough will deepen over the
southeastern US through at least Wednesday. At the surface, a wet
week is expected as a cold front - which is forecast to extend
from low pressure over the southwest Atlantic - stalls across east
central Florida through the week. The aforementioned front is
forecast to meander between north central and south central
Florida which will result in a tricky forecast for where the
heaviest rainfall, as well as the greatest flooding potential will
be each day. Either way, high rain chances (80-90%) are forecast
which are forecast to gradually reduce mid to late week to 60-70%
by Friday. The ECMWF and NAEFS ensembles indicate PWAT values
(2.0"+) towards the 97.5th+ percentile on Tuesday and Wednesday.
The WPC has outlooked much of east central Florida on Tuesday in a
Marginal Risk (level 1 out 5) for excessive rainfall.
Deterministic models show relatively warm 500mb temperatures
coupled with moderate MUCAPE values and substantial cloud cover.
Therefore, the main concerns at this time for east central Florida
will be showers and lightning storms capable of heavy rainfall
which will have the potential to result in flooding of roadways
and low- lying areas. Temperatures will be dependent on the
position of the stationary boundary with seasonable to below
normal temperatures forecast.

.MARINE...
Issued at 300 AM EDT Sat Oct 3 2026

Currently-Today... Favorable boating conditions are expected
outside of showers and lightning storms. Isolated to scattered
northwest showers and lightning storms are forecast this morning
before re-developing into the afternoon. There is the potential
for isolated strong storms capable of wind gusts to 34kts or
greater. East- southeast winds at 10-15kts with gusts up to 20kts
are expected. Seas to 2-3ft with up to 4 ft over the Gulf Stream
are forecast.

Sunday-Wednesday... Mostly favorable boating conditions are
expected outside of showers and lightning storms with onshore low
level flow in place through Sunday. Boating conditions deteriorate
and become hazardous on Wednesday. High pressure is expected to
gradually shift east over the western Atlantic to the north of
east central Florida before a cold front/stationary boundary is
forecast to gradually move southeast over east central Florida on
Tuesday. Generally, scattered to numerous/widespread showers and
lightning storms are forecast each day with the highest rain
chances in the afternoon hours. The potential exists for isolated
strong storms capable of wind gusts at 34kts or greater. East-
southeast winds at 10-15kts with gusts to 20kts are forecast to
weaken on Sunday to 6-12kts before becoming light and variable on
Monday. Winds are forecast to gradually increase from north to
south across the waters on Tuesday and become hazardous over the
Volusia county waters by Tuesday night as low pressure develops
over the southwest Atlantic. Seas to 2-3ft are forecast before
increasing rapidly from north to south on Wednesday at around
5-10ft.

.AVIATION...
(06Z TAFs)
Issued at 155 AM EDT Sat Oct 3 2026

VCSH included at all east central Florida terminals to start the
06Z TAF. Brief VIS/CIG reductions will be possible in heavy
downpours, and have included SHRA TEMPOs (06Z-08Z) along the coast
from MLB southward where coverage is currently highest. Rounds of
showers and an occasional storm are generally forecast to persist
along the coast through the morning period, but have VCSH ending
by 09Z across the interior. Could potentially see VCSH needing to
be extended a little longer at LEE. Looking towards the
afternoon, guidance highlights the highest coverage of convection
across the far interior. Therefore, have kept mention of
afternoon VCTS at MCO/ISM/LEE with the 06Z TAF. Winds continue
from the east-southeast up to 12 kts, becoming locally gusty near
showers and occasional storms.
