.KEY MESSAGES...
Issued at 220 PM EDT Mon Jul 6 2026

- Deep moisture and light southwest flow will continue high
  afternoon and evening rain chances along the sea breeze
  collision through Tuesday. A few strong storms will be capable
  of frequent lightning strikes, localized wind gusts of 45-55
  mph, and heavy rainfall.

- Drier air builds mid to late week, noticeably reducing rain
  chances from Thursday onward.

- Near to slightly above normal temperatures continue this
  afternoon. A building HeatRisk is expected mid to late week with
  temperatures increasing into the mid to upper 90s across the
  interior.

&&

.DISCUSSION...
Issued at 220 PM EDT Mon Jul 6 2026

Current-Tuesday...Highest afternoon/evening rain chances across the
eastern peninsula with sea breeze/boundary collisions. ISOLD-SCT
lightning storms will develop initially along the inland moving
sea breezes, with coverage and intensity (SCT-NMRS/50-70% today &
30-60% Tue) increasing late day/early evening from numerous
boundary collisions. Storm steering will be light out of the SW/W
bringing storms back to the coast, though movement will be erratic
at times surrounding strong collisions. A few storms locally
strong with primary impacts of frequent lightning strikes, gusty
winds of 40-55 mph locally, and heavy downpours leading to
minor/nuisance flooding which will be handled with Flood
Advisories as necessary. Activity will diminish thru mid-late
evening, though light debris rainfall could linger a bit. Skies
gradually thinning thru the night.

Max temps in the L-M90s each day with peak heat indices 102-107F
ahead of sea breeze/precip. Min temps consistent and in the 70s
with conditions remaining very humid.

Wed-Sun...Weak high pressure ridging continues across the central to
south/central FL peninsula into the weekend. Drier air forecast
Thu/Fri with arrival of Saharan Dust, then a potential resurgence
of moisture this weekend. ISOLD-SCT (20-50%) showers and storms
forecast on Wed, then mostly dry on Thu (5-20% - highest moisture
north of I-4), (10-40% - south) for Fri, and 20-50% for this
weekend. The main weather story for this period will likely be the
building heat across the area. Mid-level ridging across the
region will become stronger as subsidence increases and H500 temps
range between -5.5C to -7.0C. All of this will lead to a period
of above normal temperatures, especially near and north of I- 4.
For much of this period expect highs in the L-M90s near the coast
and M-U90s into the interior - highest values near/north of I-4. A
building HeatRisk is expected to affect those without adequate
cooling and hydration. Trends will be monitored for any potential
Heat Advisories as peak heat index values may near or exceed the
108F threshold across portions of the area by late week.

&&

.MARINE...
Issued at 220 PM EDT Mon Jul 6 2026

Thru Fri...Weak high pressure ridging will continue across the
central/south-central FL peninsula thru the period. This will
produce generally favorable winds/seas this week. Primary boating
concern will center around afternoon/evening lightning storms thru
mid-week that may affect the intracoastal and near shore waters.
Light SW/S flow will transition onshore each afternoon with sea
breeze formation and push inland. Highest rain chances today will
promote SCT to locally NMRS coverage, with SCT coverage near the
coast into Wed before drier air filters into the area Thu/Fri
with reduced chances. Late aftn/evening winds may increase to
14-17 kts over the open Atlc, but otherwise speeds AOB 15 kts
outside of storms. Winds/seas locally higher invof convection.
Seas 1-2 ft occasionally increase to 3 ft far offshore early this
week, and by Thursday, seas build to more widely range 2-3 ft
across the local waters (perhaps 4 ft briefly well offshore north
of Cape).

&&

.AVIATION...
(18Z TAFs)
Issued at 122 PM EDT Mon Jul 6 2026

Scattered showers and lightning storms have formed along the west
and east coast sea breeze this afternoon, with the west coast sea
breeze being more active. High coverage of showers and storms
are expected for this afternoon and evening, with the sea breeze
collision forecast near to just west of I-95 and east of Orlando
this afternoon (generally around 21-23Z). Lingering showers and
storms will be possible through 04Z in some locations. Have
maintained TEMPOs for VIS/CIG reductions beginning
over the interior after 20Z, spreading eastward over the next few
hours. Gusty winds near 45 KT will be possible in the strongest
storms. Otherwise, winds remain 10 KT or less through the period.
Dry conditions with light and variable winds overnight. VFR
conditions prevailing outside of convection through the period.
