...New UPDATE...

.KEY MESSAGES...
Updated at 224 PM EDT Thu Oct 1 2026

 - A high risk of rip currents remains in place across the
   Atlantic Coast beaches through the rest of the week.

 - Chances of showers and thunderstorms will continue through the
   rest of the week and into the upcoming weekend, however,
   conditions will gradually return to more of a typical late
   rainy season pattern over the weekend.

.UPDATE...
Issued at 224 PM EDT Thu Oct 1 2026

The thunderstorms and heavy rainfall from earlier this morning has
pushed off to the north, leaving some light to moderate rain still
occurring over the Lake Okeechobee region as well as Palm Beach
County. This batch of rain and thunderstorms has stabilized the
atmosphere which will help to cut back on additional thunderstorm
development over a good portion of the region through the rest of
the afternoon hours. An abundance of cloud cover will linger
over most of South Florida through the rest of the afternoon as
well which will help to keep this rain cooled airmass in place
during this time frame. With a mid level shortwave impulse still
nearby, some additional showers and thunderstorms may develop
heading into the evening hours especially across areas where
breaks in the clouds develop. This could create pockets of higher
instability especially heading into the early evening hours. Any
additional shower and thunderstorm activity should gradually lift
off to the northwest as tonight progresses and the mid level
impulse starts to pull away from the region. Low temperatures
tonight will generally range from the lower 70s across interior
portions of Southwest Florida to the upper 70s across the east
coast metro areas.

.SHORT TERM...
(Today through Friday)
Issued at 403 AM EDT Thu Oct 1 2026

Ensembles and EURO solutions depict an upper-lvl regional pattern
characterized by a transitional setup, with a mid/upper lvl trough
departing from the region and into the W Atl, while a stationary
remnant front draped across northern Florida dissipates.
Meanwhile, the W Atlantic high will keep its ridge axis just along
northern Florida, and a prevailing ESE flow across SoFlo during
the short term.

Deep moisture advection will continue today, with 00Z MFL and
sounding data showing PWATs in the 2.1-2.2" range, but latest High-
res solutions keep widespread cloud cover in place across SoFlo,
along with SBCAPE in the 1K-1.8K J/kg and LIs in the -3 to -5 C
range. All these parameters depict a marginally to moderately
unstable air mass, with the aforementioned cloud cover probably
capping the severe convective potential.

POPs will surge into the 70-80% range this afternoon, with
highest chances south of I-75. Therefore, greatest threat will
again be potential for localized flooding, while poor lapse rates
and weak deep-layer wind shear will keep a low level threat for
severe storms. High-res solutions also continue to show streaming
early morning showers with some embedded storms, so showers could
happen throughout the day. Overall rainfall accumulations should
happen in the 0.5-2.0 inches, but isolated higher amounts will
certainly be possible with slower-heavier downpours.

Similar weather pattern expected on Friday, except for some drier
air expected to begin filtering into the mid levels and bringing
POPs down to the 40-50% range.

Cloud coverage could help moderate temperatures through the period,
with highs in the mid 80s and lows in the low 70s.

.LONG TERM...
(Friday night through Wednesday)
Issued at 403 AM EDT Thu Oct 1 2026

Models show a summer-like weather pattern to begin the long term
with the Atlantic high ridge axis remaining just north of the area
and keeping a generally E/ESE wind regime in place through the
weekend.

Early afternoon convection will likely initiate along the east coast
sea breeze, then gradually pushing inland and west through the late
afternoon and early evening hours each day. Models remain fairly
consistent in showing a rather sharp gradient of POPs with 30-40%
for the Atlantic metro areas, and upwards of 70% for the Gulf coast.

For next week, a return to a more widespread wet and unsettled
pattern is shown by guidance as a trough deepens over the E
CONUS. An associated sfc boundary reaches the northern portions of
the peninsula in the Monday-Tuesday timeframe, although the
specific timing of this potential front remains uncertain. But
regardless of the final outcome, guidance in general show coverage
becoming widespread by late Monday and through Tuesday, with
highest NBM POPs well into the 80% range by Tuesday afternoon.

Temperatures seems to steadily warm up back into the upper 80s to
low 90s through the weekend, especially as easterly flow and
moisture return to the area.

.AVIATION...
(18Z TAFS)
Issued at 133 PM EDT Thu Oct 1 2026

Scattered to numerous showers and isolated storms will continue
to bring periods of MVFR or IFR to KDJT through 19-20z. Across
the rest of the east coast terminals, showers will gradually
dissipate as the afternoon progresses bringing a return to VFR
conditions through the evening hours. ESE winds of 10 to 15 kts
will generally remain in place through the evening hours. At KAPF,
VFR conditions will prevail, however, some scattered shower
activity may develop near the terminal through the late evening
hours.

&&

.MARINE...
Issued at 403 AM EDT Thu Oct 1 2026

Easterly winds 10-15 kts this morning will increase into the 15-20
kts range by the late morning hours as surface high strengthens over
the western Atlantic. The situation will be closely monitored in
case an Advisory becomes necessary. Seas gradually build into the
3-5 ft today as winds surge. Isolated to scattered showers will
develop each day, which may result in locally hazardous winds and
seas.

&&

.BEACHES...
Issued at 403 AM EDT Thu Oct 1 2026

Coastal flooding is still possible along the entirety of coastal
South Florida during high tide cycles today. A Coastal Flood
Statement remains in effect for the Atlantic coastline until this
afternoon, and for Mainland Monroe, and coastal Collier through
noon today. Minor coastal flooding is possible within 1.5-2 hours
of the peak of high tide.

A High Risk if Rip Currents is also in effect for all Atlantic
beaches through at least Saturday evening.
