- An active weather pattern will persist across east central
  Florida this weekend and into next week, with scattered to
  numerous showers and storms possible each afternoon.

- A moderate risk of rip currents is forecast at all east central
  Florida beaches; always swim near a lifeguard!

.DISCUSSION...
Issued at 300 AM EDT Sat May 30 2026

Today-Tonight...Broad high pressure at both the surface and in
the mid-levels will remain situated south of the Florida peninsula
today, with a weak quasi-stationary frontal boundary forecast to
remain draped across the southeastern US. This setup will maintain
predominantly westerly flow at the surface and aloft as well as a
plume of tropical moisture across the Florida peninsula, with
PWAT values 2" and greater persisting areawide. A weak shortwave
looks to traverse the peninsula this afternoon, leading to a
slight increase in westerly flow aloft. This will serve as a
limiting factor to progression inland of the east coast sea breeze
this afternoon. The east coast sea breeze will remain pinned to
the coast with an eventual sea breeze collision leading to greater
development along the east central Florida coastline late this
afternoon into the evening hours. Rain chances range from 30% to
60% across east central Florida today, with the highest chances
primarily focused along the Volusia and Brevard coasts. Storm
development will be possible with this activity, though the moist
atmospheric profile present across the area means that the primary
concern with activity today remains heavy rainfall that could
lead to localized flooding. Rainfall totals of 1-3" will be
possible, though some places may exceed 3", especially if there
are multiple rounds of rainfall in a given location. Modest
instability will allow for frequent lightning strikes and wind
gusts up to 50 mph within the strongest storms. Brief spin-ups
cannot be ruled out entirely along boundary collisions, though
confidence in this remains very low. Given the prevailing westerly
flow at the surface and aloft, shower and storm activity will
move eastward and offshore into the overnight hours, with mostly
dry conditions anticipated tonight.

The moist air mass will allow for cloud coverage to slowly build
throughout today. This will help limit daytime heating, though
temperatures are still forecast to reach the upper 80s areawide.
Higher humidity will lead to peak heat indices climbing into the
mid to upper 90s across the area, with the highest values focused
along the coast. Overnight lows will fall into the low to mid 70s.

A moderate risk of rip currents continues at all east central
Florida beaches. If heading to the beaches, be sure to swim near a
lifeguard.

Sunday-Tuesday...The pattern through the remainder of this
weekend and into the start of next week will stay relatively
unchanged compared to today. The broad surface and mid-level high
pressure south of the peninsula will remain in place with the
quasi- stationary boundary anticipated to stay north of central
Florida. West to northwest flow persists at both the surface and
aloft, with moisture remaining plentiful across the peninsula
through at least Tuesday. This setup will allow for continued
scattered to numerous shower and storm development each afternoon
as the sea breeze collision occurs across the eastern portion of
the peninsula. Lightning and wind gusts will be possible with
storm development, but heavy rainfall and flooding concerns will
remain at the forefront each day due to the moist atmospheric
profile. Widespread rainfall totals of 1-3" will be possible each
afternoon, but localized higher amounts exceeding 3" cannot be
ruled out, especially in locations that receive multiple rounds of
rainfall. Saturated locations from the prior day will also be
more susceptible to flooding. Activity will continue to push
offshore into the overnight hours.

Temperatures are forecast to remain near normal through Tuesday,
with highs climbing into the upper 80s to low 90s. Higher humidity
from the moist air mass will cause peak heat indices to reach the
mid 90s to low 100s, so adequate hydration and breaks in air
conditioning will be important for those spending extended periods
of time outdoors. Lows will generally remain in the low to mid
70s each night.

Wednesday-Friday...By the middle of next week, a mid-level trough
will swing eastward and offshore, causing the quasi-stationary
boundary to slowly sink southward across the Florida peninsula.
Surface high pressure will then filter in behind the boundary into
Friday, allowing for some drier air to settle across east central
Florida towards the end of the week. Winds are forecast to
gradually veer and become more onshore as the pattern slowly
shifts, leading to the highest rain chances shifting away from the
coast and towards the interior late next week. Storm chances also
remain in the forecast, with lightning, gusty winds, and brief
heavy downpours all remaining possible. The Euro has trended
closer to the GFS with the latest model guidance suite, favoring a
drier solution across the peninsula. The NBM has been slower to
integrate this into its guidance, keeping rain chances a bit
higher in the extended. Would not be surprised to see PoPs trend
downward with the next forecast package. Temperatures are forecast
to trend a bit downward as the boundary shifts south of the
peninsula, with highs generally in the low to mid 80s areawide and
lows in the upper 60s to low 70s.

.MARINE...
Issued at 300 AM EDT Sat May 30 2026

Winds and seas are forecast to remain favorable across the local
Atlantic waters as broad high pressure stays south of the area and
a quasi-stationary boundary remains north of the area. Seas of 1
to 3 feet are forecast through this weekend with offshore winds of
5 to 10 knots in the mornings picking up to 10 to 15 knots in the
afternoons. Along the immediate coast, some onshore flow cannot
be ruled out as the east coast sea breeze develops and moves
inland. Monday and Tuesday, seas build to 3 to 5 feet as a low
pushes eastward into the Atlantic well north of the area, with
winds generally remaining offshore at 10 to 15 knots. Wednesday,
boating conditions begin to deteriorate as the quasi-stationary
boundary drifts southward, causing winds to veer out of the east
at 10 to 15 knots, allowing seas to build to 4 to 6 feet. A brief
period of 7 foot seas also cannot be ruled out across the offshore
waters. Onshore winds are anticipated to persist through the
extended period, with seas staying between 3 to 6 feet.

Isolated to scattered showers and storms will be possible across
the local Atlantic waters over the next several days, especially
in the evenings as activity from the peninsula moves offshore and
across the waters. Storm hazards include cloud-to-water lightning
strikes, wind gusts exceeding 34 knots, and slightly higher seas
near stronger storms. Activity will diminish through the overnight
hours.

.AVIATION...
(06Z TAFs)
Issued at 155 AM EDT Sat May 30 2026

Mainly VFR to continue this TAF period. Will be monitoring some
intermittent lower CIG/VIS across northern sites thru 12z but
models suggest little in the way of significant reductions due to
low clouds or BR/FG. WNW winds 9-12 kt are established after
15-17z, bringing the west coast breeze quickly across the
peninsula. VCTS included earlier for western/northern terminals,
ending by 00-03z across southern sites. Confidence is highest in
TS at DAB for now, lower elsewhere, so will wait on TEMPOs for
now.
