.KEY MESSAGES...
Issued at 215 AM EDT Tue Jun 17 2025

- High pressure builds across east central Florida, limiting rain
  and storm chances through Thursday. Rain and storm chances
  increase into Friday due to greater moisture, but fall once
  again into the weekend and early next week.

- Afternoon highs reach the low to mid 90s most afternoons, with
  peak heat indices ranging from 100 to 105. Heat stress continues
  to be a concern, with widespread Moderate HeatRisk and Major
  HeatRisk focused across the greater Orlando area.

.DISCUSSION...
Issued at 215 AM EDT Tue Jun 17 2025

Today-Tonight...Ridging both aloft and at the surface will help
limit shower and storm chances across east central Florida today,
along with a drier air mass that has built across the peninsula.
Mostly dry conditions are anticipated across east central Florida
today as a result of this set-up, but some isolated activity still
cannot be fully ruled out along the east coast sea breeze and the
eventual sea breeze collision in the late afternoon and evening
hours. Some of the CAM guidance does show this, but confidence
remains low, so only have a 20 to 30 percent chance for showers and
storms in the forecast across the interior. If any storms were to
develop, the main threats would include frequent lightning strikes,
wind gusts to 50 mph, and brief downpours. Any activity that manages
to develop would diminish into the overnight hours, with dry weather
anticipated tonight.

With the lower rain chances and the drier air present, heat remains
a concern for east central Florida. Highs in the low to mid 90s are
forecast, with the warmest temperatures focused across the interior.
While the drier air will help limit humidity slightly, it may still
feel muggy at times. Peak heat indices are forecast to range from
100 to 105, and a Moderate to Major HeatRisk is anticipated. Staying
well-hydrated and taking breaks in the shade or in an air
conditioned building are strongly encouraged if spending extended
periods of time outdoors. Those particularly sensitive to the heat
or those not acclimated to Florida heat may be at a higher risk of
heat-related stress and illness. Conditions overnight remain warm
and muggy, with lows in the low to mid 70s.

Wednesday-Monday...Mid-level ridging remains over the Florida
peninsula through Thursday, erodes into Friday, and is replaced by a
stronger mid-level ridge over the weekend and into early next week.
At the surface, the Atlantic high remains generally in place, with
the ridge axis slowly drifting northward through the period. Pockets
of dry air continue to move towards the area through a majority of
the period, keeping rain and storm chances generally between 40 to
50 percent, and slightly lower along the coast. The exception to
this occurs on Friday as increasing moisture locally is anticipated
as the mid-level ridge erodes, with a return of 50 to 70 percent
rain and storm chances. Rain and storm chances diminish during the
overnight hours, with some isolated activity possible across the
local Atlantic waters.

Hot conditions are forecast to continue across east central Florida,
with highs in the low to mid 90s each afternoon and peak heat
indices reaching 100 to 105. While these heat indices continue to
remain below Heat Advisory criteria, a Moderate to Major HeatRisk is
forecast to persist across east central Florida. Adequate cooling
and hydration will be key in avoiding any heat stress for residents
and visitors alike if spending extended periods of time outdoors.
Lows remain consistent through the period in the low to mid 70s.

.MARINE...
Issued at 215 AM EDT Tue Jun 17 2025

An area of high pressure will remain in place across the local
Atlantic waters, with the ridge axis forecast to slowly drift
northward through the period. This will result in south to
southeasterly winds becoming more easterly into early next week.
Wind speeds remain fairly consistent at 5 to 10 knots overnight
into the early morning hours and 10 to 15 knots each afternoon
after the development of the east coast sea breeze. Seas are
forecast to remain between 2 to 3 feet. While conditions across
the local waters are anticipated to remain fairly dry through the
next few days, isolated to scattered shower and storm activity
cannot be ruled out.

.AVIATION...
(06Z TAFs)
Issued at 140 AM EDT Tue Jun 17 2025

VFR to persist thru much of the TAF period. Light SSE winds will
continue thru 14z (variable at times) before gradually becoming
ESE as the sea breeze develops after 16z-18z. Gusts around 20-25
kt are possible, especially at coastal terminals. VCTS was
preserved for inland terminals after 20z, only slightly delayed
by ~1 hr. Confidence remains too low at this time for TEMPOs.
Gradual clearing is forecast after 03z Wed. with light/variable
wind.
