.DISCUSSION...
Issued at 255 AM EDT Wed Aug 19 2026

Today-Tonight...Broad mid-level ridging continues to weaken today
with the surface ridge axis remaining well south of central
Florida. A frontal boundary will remain quasi-stationary across
the southeast US, with a moist air mass situated over east central
Florida. Light west to southwest winds will persist both at the
surface and aloft, with early development of showers and storms
anticipated along the west coast of Florida. Convection will
spread across the peninsula through early afternoon, with
interactions along the delayed east coast sea breeze prompting
further shower and storm development. The environment continues to
look favorable for strong storm development across east central
Florida, with adequate daytime heating supporting instability, dry
air aloft supporting downdraft potential, and PWATs exceeding 2"
areawide supporting heavy rainfall. Hazards today will include
frequent lightning strikes, wind gusts of 45 to 55 mph, and heavy
downpours. Quick accumulations of 1-3" leading to localized
flooding cannot be ruled out. Boundary interactions may result in
brief rotation in the form of funnel clouds, though confidence in
this remains low. Westerly winds will continue to push activity
offshore through the afternoon and evening hours, with drier
conditions forecast overnight across the peninsula.

August heat persists across east central Florida, with highs
climbing into the mid 90s and lows remaining near to above normal
in the mid to upper 70s. Peak heat indices will continue to reach
and exceed advisory criteria, with another Heat Advisory areawide
between 10 AM and 8 PM. Residents and visitors should continue to
practice heat safety to avoid developing heat-related illness.
Adequate hydration, wearing lightweight, lightly colored clothing,
and taking frequent breaks in the shade or an air conditioned
building will be important and as always, never leave children or
pets unattended in vehicles.

Thursday-Tuesday...An active pattern will persist across east
central Florida through this week and into next week. A localized
mid-level low is forecast to develop across the Gulf and northern
Florida late this week but is forecast to be absorbed by a
strengthening trough extending southward across the eastern US. At
the surface, high pressure will remain situated south of the
Florida peninsula as the quasi-stationary boundary draped across
the southeastern US generally remains in place. This set-up will
maintain a plume of moisture across the Florida peninsula, with
daily afternoon shower and storm development forecast through this
week and into the next. PoPs remain near normal at 40-60% each
day with the typical afternoon storm hazards anticipated with
development. Activity will diminish into the late evening and
overnight hours. Outside of the daily convection, heat will
continue to be a concern. Highs in the mid 90s on Thursday will
trend closer to normal values from Friday onward, but humid
conditions will persist with peak heat indices exceeding 100F
each afternoon. Additional Heat Advisories may be needed for
Thursday and even Friday across portions of the area, though
values are forecast to remain just shy of advisory criteria from
Saturday onward. Will continue to closely monitor and issue heat
products as needed.

.MARINE...
Issued at 255 AM EDT Wed Aug 19 2026

Generally favorable boating conditions are forecast across the
local Atlantic waters through this week and into the weekend as
the surface ridge axis remains well south. West to southwest winds
will persist at 10 to 15 knots, becoming south to southeast
during the afternoon hours as the east coast sea breeze develops.
Seas will remain between 1 to 3 feet, highest across the offshore
waters. A moist air mass will remain in place across the area,
with offshore-moving showers and storms forecast during the
afternoon and evening hours. Storms will be capable of producing
frequent lightning strikes, wind gusts in excess of 30 knots,
heavy downpours, and locally higher seas. Activity is anticipated
to diminish into the overnight hours.

.AVIATION...
(06Z TAFs)
Issued at 143 AM EDT Wed Aug 19 2026

VFR conditions outside of convection. Prevailing westerly flow
backs SE in the afternoon at the coast as the sea breeze develops
after around 18/19Z. Winds remain around 10 kts or less. The sea
breeze will be the focus for convection today, with TEMPOs
included for coastal sites from 20-0Z. Interior locations could
see a few storms, with VCTS included there, but the highest
chances will remain east of MCO/ISM. Convection looks to diminish
by around 0Z, though a few showers may linger near the coast
through around 2Z.
