.SHORT TERM...
(Rest of today through Sunday)
Issued at 1240 PM EDT Sat May 25 2024

Portions of southeast Florida could see scattered shower activity
once again today as ridging erodes and the sea breezes become the
driving features for convection. The 12Z sounding showed moderate
instability and moisture in the lower levels which could support a
few strong thunderstorms, with current values of SBCAPE and PWATs
at 1300 J/kg and 1.5 inches, respectively, which could climb up
to values greater than 3000 J/Kg and near 2 inches this afternoon.
This - combined with growing lapse rates as warming continues -
will support a damaging wind threat and the chance for localized
flooding across western-most portions of the southeast FL metro
areas where the sea breezes are forecast to collide. An additional
risk exists for small hail with some of the stronger storms, but
warmer temperatures aloft will help limit this risk.

Temperatures will reach the mid 90s later this afternoon ahead of
the convection as winds remain out of the S/SW, with heat indices
in the low 100s possible. Some relief will be felt across the
East Coast once the sea breeze pushes in, but we`re talking a few
degrees of difference, if that.

Ridging will build back on Sunday with only isolated chances for
showers and storms in the forecast. Lack of cloud coverage and
convection will once again allow temperatures to climb into the mid
90s across much of South FL.

.LONG TERM...
(Sunday night through next Friday)
Issued at 237 PM EDT Sat May 25 2024

Weather looks more unsettled this upcoming week as the ridge breaks
down and several impulses pivot around the base of a trough that
sets up over the eastern US. At the surface, a frontal boundary will
linger north of Lake Okeechobee in the mid to end week time frame.
Monday will be the driest day of the week with 20-30 PoPs for mainly
afternoon and early evening diurnally driven convection. PoPs then
increase to 40-50 for Tuesday through Friday with the added moisture
and instability in place across South FL. Forecast soundings for the
middle to end of next week show deep layer moisture with PWAT values
in excess of 2 inches. This will lead to efficient rain rates with
the stronger thunderstorms, and could potentially lead to some urban
flooding concerns across the metro, especially if multiple storms
move over the same areas within a short period of time. Still plenty
of time to evaluate this over the next several days. Regardless, the
increase in convection coverage next week could bring some much
needed relief to portions of South FL still experiencing drought
conditions, especially around the lake region.

No relief expected at least in the early to middle portion of next
week from the heat, with highs generally in the low to mid 90s
across the metro, and mid to upper 90s over the interior. Max heat
indices will be over 100 degrees each day through at least Thursday.
Overnight lows will generally be in the 70s to around 80. Some minor
relief is possible late next week into next weekend as the low level
flow becomes northeasterly, however temps are likely to remain above
normal.

.AVIATION...
(06Z TAFS)
Issued at 117 AM EDT Sun May 26 2024

Generally VFR conditions will prevail through the TAF period.
Isolated showers and thunderstorms will be possible this afternoon
near the east coast terminals but currently confidence in coverage
is too low to include mention of TS in current TAFs. Light and
variable winds this morning will shift to the SE at the east coast
terminals and westerly at KAPF this afternoon.

.MARINE...
Issued at 1240 PM EDT Sat May 25 2024

Generally benign conditions should prevail across local waters
through the period. Scattered showers and thunderstorms are expected
this afternoon with locally enhanced winds and seas possible in
storms particularly over the Atlantic waters. Exercise caution
conditions could be possible Sunday-Monday as southerly winds 10-15
kts prevail over the local waters.

.BEACHES...
Issued at 1240 PM EDT Sat May 25 2024

With generally southerly flow prevailing, the risk of rip
currents across East Coast will remain low through the holiday
weekend.
