.KEY MESSAGES...
Issued at 251 PM EDT Mon Jun 8 2026

- Around 2 PM today, a 6.1 magnitude earthquake occurred west of
  Cuba and was felt locally in east-central Florida. There was NO
  tsunami threat to the coast. Visit usgs.gov for more info.

- Low rain chances continue on Tuesday before moisture builds mid
  to late week, resulting in higher rain and storm chances,
  especially into the upcoming weekend.

- Near to slightly above normal temperatures will continue, with
  the increasing moisture leading to greater chances for peak heat
  indices exceeding 100F late this week.

- At the beaches, a moderate risk of rip currents continues.
  Always swim near a lifeguard!

.DISCUSSION...
Issued at 251 PM EDT Mon Jun 8 2026

Now-Tonight...In a bit of news on this quiet weather day, a 6.1
magnitude earthquake occurred around 2 PM, off of the western coast
of Cuba. Reports were received of the earthquake being felt locally
across east central Florida, and there was no tsunami threat with
this activity. For more information, please visit usgs.gov.

Plenty of sunshine this afternoon is supporting temperatures in the
mid/upper 80s to around 90 degrees. With a few more hours left of
peak heating, temps are on track to reach the low 90s across much of
the interior. Satellite imagery shows a few cumulus clouds across
St. Lucie and Martin counties, thinly highlighting the westward-
advancing east coast sea breeze. With appreciable dry air in place
between 500-850mb, a dry forecast is maintained through the rest of
the afternoon and evening. Tonight, temperatures will settle into
the low to mid 70s (upper 70s Treasure Coast) as muggy conditions
build areawide. Shallow, westward-moving showers look to develop
after midnight over the Atlantic. Some of this activity could
approach the coast prior to daybreak Tuesday, especially from the
Cape northward.

Tuesday-Wednesday...Surface high pressure over the Mid
Atlantic/Northeast U.S. slides east over the Atlantic, with its axis
roughly centered over the FL Peninsula. As the upper pattern over
the north-central CONUS becomes a bit more active, H5 ridging over
the eastern Gulf will shift west toward the TX Gulf Coast. Locally,
easterly winds continue each day (10-15 mph) with the east coast sea
breeze pushing inland in the afternoon. Tuesday morning, a low
chance (20%) of coastal showers was included as shallow marine-layer
showers push toward the coast. This activity may translate inland
late morning into the early afternoon hours, especially as the sea
breeze gets going. Still, this update maintains only a 15-24% chance
of showers. An isolated lightning storm cannot be ruled out,
especially across the interior, where surface heating builds
instability a bit more. Similarly, coastal showers are possible
Wednesday morning, but with more moisture available Wednesday
afternoon (PW values 2"+), rain chances climb to 30-55% across the
interior. A few more lightning storms are possible then, too, with
MUCAPE building to ~1000+ J/kg. Daytime temperatures ranging from
the upper 80s to low 90s appear most likely with heat indices
starting to approach the 100-degree mark by Wednesday.

Thursday-Sunday (modified)...Broad mid-level ridging across Florida,
the Gulf, and Mexico is forecast to remain in place through the end
of this week and into the weekend. At the surface, the broad high
pressure across the Atlantic will settle a bit farther south and
east. The ridge axis will extend towards the Florida peninsula,
resulting in south to southeast flow. Late week, the pressure
gradient is forecast to weaken, with winds becoming lighter and more
variable into this weekend. The persistent southerly flow will allow
for moisture advection to occur, with PWATs recovering into the 1.8-
2.0+" range. Greater moisture and convergence along the east coast
sea breeze will lead to scattered to numerous showers and storms
each afternoon. Following the typical summertime diurnal pattern,
activity will peak in the afternoon and early evening hours,
gradually diminishing overnight. A low chance of showers (and a
storm or two) will continue overnight across the local Atlantic
waters.

Models are in somewhat better agreement this afternoon, relative to
the amount of moisture present across the peninsula. While there
should still be some adjustments to location/magnitude of the
highest rain chances, some focus may shift toward the central and
eastern portion of the peninsula this weekend/early next week as
light surface flow turns S/SW. Temperatures across east central
Florida will remain near to slightly above normal through the
extended period and with the humid conditions, peak heat indices
exceeding 100F are becoming likely. Residents and visitors should
plan ahead for a stretch of hotter conditions, especially if
spending extended periods of time outdoors: remain adequately
hydrated, avoid the hottest points of the day, and take frequent
breaks in the shade or an air-conditioned building. Muggy, warm
nighttime temperatures will provide little relief from the daytime
heat.

.MARINE...
Issued at 251 PM EDT Mon Jun 8 2026

Generally favorable boating conditions are forecast to continue this
week. Easterly winds 10-14 kt gradually veer more southeasterly
Wednesday/Thursday, before weakening further and becoming more SSE
into the weekend. Moisture increases each day with an uptick in rain
and lightning storm chances. Isolated/scattered showers and storms
will develop overnight into the early morning hours, until late week
or into the weekend, when some afternoon/evening activity could push
back toward the coast and nearshore waters. Locally higher
winds/waves are possible in the vicinity of any storms.

.AVIATION...
(18Z TAFs)
Issued at 144 PM EDT Mon Jun 8 2026

Dry conditions persist today, remaining mostly VFR. Low chances
for rain return to the forecast Tuesday with VCSH mentioned along
the coast prior to sunrise. Potential for VCSH may then exists
across the interior terminals into Tuesday afternoon. Light
easterly flow increases to 10-12 kts behind the sea breeze this
afternoon, diminishing late this evening.
