.KEY MESSAGES...
Issued at 300 AM EDT Sat Aug 15 2026

- A Heat Advisory is in effect for all east central Florida
  counties between 10 AM and 8 PM for peak heat indices of 108F to
  112F. Practice heat safety!

- Heat will remain a concern across east central Florida over the
  next several days as afternoon highs near records in some spots
  and peak heat indices near or exceed Heat Advisory criteria.

- Below normal rain and storm chances are forecast to persist
  through this weekend and into early next week due to drier air
  aloft from Saharan dust. Any storms that develop will be capable
  of producing lightning strikes and strong, gusty winds.

- Increasing moisture Tuesday onward will result in a return of
  near-normal rain and storm chances across east central Florida.

.DISCUSSION...
Issued at 300 AM EDT Sat Aug 15 2026

Today-Tonight...Ridging aloft will keep the surface high across
the Atlantic in place, with the surface ridge axis extending
towards the Florida peninsula. This will result in persistent
light and variable winds locally through this morning until the
east coast sea breeze develops and pushes inland, with winds
becoming south to southeast around 10 mph through this afternoon.
Isolated to scattered shower and storm development will be
possible in association with the sea breeze and its intrusion
inland, but chances for development remain low (20-40%). The best
chances (30-40%) are focused across the Treasure Coast and near
Lake Okeechobee where a plume of moisture lifts northward today.
North of this area, a slightly drier air mass will limit rain and
storm chances to around 20%. Sufficient daytime heating across the
area today will provide enough energy for convective development
and drier air aloft will act to enhance any potential wind gusts.
Any storms that develop will be capable of producing lightning
strikes, wind gusts up to 50 mph, and brief heavy downpours.
Activity is anticipated to diminish late this afternoon into the
evening hours with a return of dry conditions overnight.

The persistent high pressure both at the surface and aloft will
support a continued warming trend across east central Florida
today. Afternoon temperatures are forecast to reach the low to mid
90s across much of east central Florida, with some locations near
and north of the I-4 corridor climbing into the upper 90s and
nearing record temperatures. These temperatures combined with
humid conditions will produce peak heat indices of 108F to 112F
today, and a Heat Advisory has been issued between 10 AM and 8 PM
across all of east central Florida. Those spending extended
periods of time outdoors are strongly encouraged to remain
adequately hydrated, wear lightweight, lightly-colored clothing,
and take frequent breaks in the shade or an air conditioned
building to help reduce the risk of developing heat-related
illness. Muggy conditions will continue into the overnight hours,
with lows in the mid to upper 70s tonight.

Sunday...Ridging aloft and at the surface will remain in place
across east central Florida on Sunday, with a plume of Saharan
dust anticipated to drift across the peninsula. This will result
in even lower rain and storm chances across the area (20%). Any
storms that do manage to develop may be capable of producing
lightning strikes, wind gusts to 50 mph, and brief downpours.
Activity will diminish into the evening and overnight hours. The
combination of the dry air aloft and the persistent high will
support a continued warming pattern locally, with afternoon highs
reaching the mid to upper 90s areawide. Maximum apparent
temperatures are anticipated to once again reach and/or exceed
108F areawide, and a Heat Advisory will likely be needed once
again across east central Florida. Practicing heat safety will
continue to be strongly encouraged through the remainder of this
weekend in order to reduce the risk of heat illness. Little relief
is anticipated into the overnight hours with lows remaining above
normal in the mid to upper 70s.

Monday-Friday...Ridging aloft becomes broader into next week with
the Atlantic high sliding southward as a weakening frontal
boundary drifts southward across the southeastern US towards the
Florida peninsula. Moisture is forecast to increase locally, with
a return to near-normal rain and storm chances across northern
portions of the area on Monday and areawide Tuesday onward.
Convection will continue to follow a diurnal pattern, with peak
coverage happening during the afternoon and early evening hours in
association with the sea breezes. Lightning, gusty winds, and
heavy downpours will all be possible with activity. Showers and
storms are anticipated to diminish into the late evening and
overnight hours. Aside from shower and storm chances, heat will
continue to be a concern through next week. Afternoon highs are
forecast to remain above normal areawide with humid conditions
still leading to peak heat indices near or even above Heat
Advisory criteria.

.MARINE...
Issued at 300 AM EDT Sat Aug 15 2026

High pressure will remain in place across the local Atlantic
waters through this weekend and into the middle of next week,
resulting in generally favorable boating conditions. West to
southwest winds will become more south to southeasterly each
afternoon as the east coast sea breeze develops and pushes inland
across the peninsula, with wind speeds forecast to remain below 15
knots through the period. Seas of 1 to 3 feet will persist across
the local waters. Isolated to scattered showers and storms will
be possible from the Cape southward today, with mostly dry
conditions elsewhere. Drier air will move across the local waters
late this weekend into early next week, keeping rain chances below
normal.

.AVIATION...
(06Z TAFs)
Issued at 113 AM EDT Sat Aug 15 2026

Continued mainly VFR through the TAF period. Dry conditions and
light/VRB winds into morning hours. Lower than normal TSRA/SHRA
chances Sat, though the light SRLY LLVL flow could help develop
ISOLD SHRA INVOF KSUA-KFPR as early as 16Z. The ECSB is forecast to
develop after 17Z, reaching KMCO/inland terminals after 22Z, and
shift winds ESE-SE 7-12 kts behind the boundary. ISOLD TSRA/SHRA are
forecast to develop on the boundary as it moves inland. A sea breeze
collision is forecast near to west of MCO Sat evening, with quiet
conditions resuming overnight.
