Issued at 230 PM EDT Fri Aug 7 2026

- An inverted trough has ushered in deep tropical moisture across
  the area, leading to high rain chances through Saturday along
  with a risk for locally heavy rainfall and minor flooding
  issues.

- Poor boating conditions continue offshore this evening, with a
  High Risk of rip currents at area beaches.

- Conditions trend drier from Sunday onward as high pressure is
  reestablished across the local waters and drier air aloft moves
  towards east central Florida.

- Hot and humid conditions will persist across east central

.DISCUSSION...
Issued at 230 PM EDT Fri Aug 7 2026

Through Tonight...An inverted trough lifting northwest from the
Bahamas and across the Florida peninsula has brought a deep plume
of tropical moisture locally, with PWATs of 2.1-2.3" areawide. The
result has been an early start to convection, with early morning
showers increasing in coverage into the afternoon hours. Active
development of showers and storms will continue through the
remainder of this afternoon into the evening hours, with PoPs
between 60-70% areawide. Despite sufficient steering flow keeping
activity moving westward, multiple rounds of showers and storms
will lead to a higher risk of flooding across east central
Florida, with rainfall accumulations of 2-4" and locally higher
amounts possible. East central Florida remains outlooked in a
Marginal Risk (1/4) of excessive rainfall today. Storm activity so
far has followed typical Florida summertime trends, with frequent
lightning strikes, wind gusts up to 50 mph, and heavy downpours
the primary concerns. The environment remains supportive for this
activity to persist through the remainder of this afternoon and
evening. Guidance continues to favor activity overall diminishing
across east central Florida beyond 8 PM, but persistent onshore
flow coupled with the higher moisture means continued shower and
isolated storm development across the local Atlantic waters is
anticipated. Some of these showers and storms may be able to push
onshore overnight and into early Saturday.

Saturday-Sunday...The inverted trough will continue to lift
northwestward across the Florida peninsula and into the Gulf on
Saturday, eventually diminishing into Sunday as the Atlantic high
reestablishes itself as the dominant surface feature across the
Florida peninsula. The plume of moisture associated with the
trough will linger across the peninsula through this weekend, with
PoPs ranging between 50-70% on Saturday and 40-60% on Sunday.
Activity on Saturday will follow a similar pattern to today, with
southeasterly flow driving development across the local Atlantic
waters and pushing it onshore, with increasing coverage across the
peninsula forecast through the afternoon hours. Weaker flow aloft
may lead to slower-moving activity Saturday, increasing the
threat for localized flooding. The area remains outlooked in a
Marginal Risk (1/4) of excessive rainfall on Saturday, with
rainfall accumulations of 2-4" and locally higher amounts not able
to be ruled out in some spots. Sunday, shower and storm
development will follow more of a diurnal pattern, with convection
primarily being driven by sea breeze development and intrusion
inland as well as any additional outflow boundaries. Storm
development will be possible each day through this weekend, though
activity looks to remain sub-severe overall. Cannot rule out a
stronger storm or two on Sunday thanks to some drier air aloft
drifting towards the area. Frequent lightning strikes, wind gusts
of 45 to 55 mph, and heavy downpours remain the primary hazards.
Each evening and into the overnight hours, anticipate activity
gradually winding down with mostly dry conditions areawide.

Temperatures will overall remain near normal through this
weekend, with highs in the upper 80s to low 90s though some
locations near and north of the I-4 corridor could see some
temperatures reaching the mid 90s. Humid conditions will keep peak
heat indices in the 100- 107F range this weekend, so be sure to
remain adequately hydrated and take breaks indoors or in the shade
if staying outdoors for extended periods of time. Lows remain in
the mid 70s.

Monday-Thursday (previous)...Atlantic ridge axis shifts back
south across the area into early next week, and then slowly shifts
farther south of the area by mid to late week as a frontal trough
pushes into the Southeast United States. This will gradually veer
low level winds from the southeast Monday to the south-southeast
Tuesday and then out of the west-southwest Wednesday into
Thursday. However, winds remain weak and the east coast sea breeze
will still form and move inland each day. Mid level ridge shifts
westward across the state and remains firmly in place through much
of next week. This combined with advection of drier air will lead
to lower than normal rain chances into next week. Forecast PoPs
are currently no more than 20-30% for each afternoon/evening. With
coverage of showers and storms remaining isolated to scattered
each day and with ridge in place, temperatures will continue to
rise, with highs in the low to mid 90s each day. Will have to
monitor for any Heat Advisories as peak heat index values may have
the potential to rise to 108-110 in some spots.

.MARINE...
Issued at 230 PM EDT Fri Aug 7 2026

Poor boating conditions will persist across the offshore waters
through the remainder of this afternoon and into the late evening
hours as an inverted trough lifts northwestward across the local
waters, with easterly winds of 15 to 20 knots and seas of 3 to 6
feet. Conditions are anticipated to improve after midnight as
winds become more southeasterly at 10 to 15 knots and seas subside
to 3 to 5 feet. The trough will continue to pull away from the
local waters through this weekend, with the Atlantic high
returning to the waters late this weekend into early next week.
Southeasterly winds around 10 knots persist through Monday,
becoming more southwesterly at 10 to 15 knots Tuesday onward as
the ridge axis shifts southwards. From Saturday night onward, seas
return to 1 to 3 feet across the local waters.

Scattered shower and storm development will continue across the
local Atlantic waters tonight through Saturday thanks to a plume
of deep tropical moisture brought to the area by the inverted
trough. Storms may be capable of producing frequent lightning
strikes, wind gusts in excess of 34 knots, and locally higher
seas. Saturday night through most of next week, drier conditions
are anticipated across the local Atlantic waters, with rain and
storm chances generally remaining around 20% or less.

(00Z TAFs)
Issued at 737 PM EDT Fri Aug 7 2026

Mostly dry at east central Florida terminals this evening.
However, have kept a mention of VCSH along the coast from MLB
southward through tonight for occasional rounds of onshore moving
showers. East winds settle to 4-8 kts tonight, gradually shifting
south-southeast into Saturday morning. A more typical pattern of
afternoon showers and storms returns tomorrow, mostly driven by
the east coast sea breeze, and afternoon VCTS is mentioned at all
terminals. Winds shift east 7-10 kts as the sea breeze passes.
