.SHORT TERM...
(Rest of today through Saturday)
Issued at 1251 PM EDT Fri Jun 23 2023

The active weather pattern continues this afternoon as South Florida
remains situated between a ridge of high pressure in the western
Atlantic and a ridge off to the west in the Southern Plains. The mid
level cut off low that has been parked over the Southeast over the
past several days is moving northward towards the Midwest and Great
Lakes region. This will allow for mid level temperatures to moderate
as the afternoon continues to progress. South to southwesterly
steering flow continues to pump in deep tropical moisture allowing
for another afternoon of scattered to numerous showers and
thunderstorms. With PWAT values over 2 inches across most of the
region, heavy downpours will continue to create the potential for
localized flooding through the evening hours especially across the
east coast metro areas. While strong thunderstorm development will
still be possible, the chances of severe thunderstorm development
will be a bit lower than it has been over the past several days.
Most of the shower and thunderstorm activity will diminish as the
evening progresses leaving mainly dry conditions across most areas
overnight. Low temperatures tonight will generally range from the
lower 70s across the Lake Okeechobee region to the upper 70s across
the east coast metro areas.

Moving into Saturday, South Florida will remain wedged in between
the two ridges of high pressure, one centered over the Southern
Plains and one over the western Atlantic. While weak mid level
troughing remains overhead, additional deep tropical moisture will
advect into the region as the day progresses. This will allow for
the coverage of showers and thunderstorms to become widespread
during the afternoon and evening hours. As mid level temperatures
continue to warm, the chances for severe thunderstorm development
will remain rather low, however, one or two storms could still
become strong containing gusty winds. With abundant moisture
filtering into the region, the potential for localized flooding will
persist especially over the east coast metro areas that have been
saturated from recent heavy rainfall over the past several days.
High temperatures on Saturday will generally remain in the lower 90s
across most of South Florida.

.LONG TERM...
(Saturday night through next Thursday)
Issued at 241 PM EDT Fri Jun 23 2023

Tomorrow Night through Thursday: As we wrap up the weekend, Sunday's
pattern looks similar to that on Saturday with a good chance for
showers and thunderstorms during the day. The weak flow and
substantial moisture will provide a prime atmosphere for slow-
moving storms with high PWATs (~2") and localized flooding
potential. The best chance for storms will be in the interior;
however, coverage for rainfall is regionwide with likelihood for
flooding in our eastern metro.

Moving into next week, there will be a change in the pattern as an
upper level ridge begins to move into the Gulf of Mexico. With this
ridging, it will prevent the deep tropical convection we have been
receiving these past few days and support our stereotypical summer
afternoon sea breeze convection. Therefore, there will still be
potential for thunderstorms (less strong to severe), but without the
tropical moisture, heavy downpours and PWATs will be much lower
(1.5-1.7"). The ensemble outlooks are forecasting much less
rainfall, but still potential for afternoon showers and scattered
thunderstorms.

Looking into the extended temperature outlook, excesssive heat
will continue in South FL with daily highs in the low to mid 90s.
With the contribution of high dew points approaching the mid-70s,
heat indices will reach the triple digits. Especially as we move
into mid-week, the HI values will be approaching heat advisory
levels for certain locations (especially interior and M-D County)
and nearing the 107-110 range. Whether reaching those levels or
not, the high temperatures will be hot and precautions should be
taken if spending excessive time outside. Overnight lows will be
in the 70s with the coastal regions keeping to the upper 70s and
slightly cooler elsewhere.

.AVIATION...
(18Z TAFS)
Issued at 1251 PM EDT Fri Jun 23 2023

Southeasterly winds will continue this afternoon across the east
coast terminals before becoming light and variable this evening.
Scattered showers and thunderstorms will develop and could affect
the east coast terminals later this afternoon into the early
evening hours. Periods of MVFR or IFR will be possible in and
around storms. At KAPF, southwesterly winds this afternoon will
become light and variable later this evening.

&&

.MARINE...
Issued at 1251 PM EDT Fri Jun 23 2023

A moderate southeasterly wind flow will remain in place across the
local waters through the weekend and into the early portion of next
week. Seas across the Atlantic waters will generally remain at 3
feet or less while seas across the Gulf waters remain at 2 feet or
less during this time frame. Scattered to numerous showers and
thunderstorms will develop over the local waters each day. Winds and
waves could be locally higher in and around showers and storms.

&&

.BEACHES...
Issued at 1251 PM EDT Fri Jun 23 2023

A moderate risk of rip currents will continue across the beaches of
Palm Beach and Broward counties as a moderate southeasterly wind
flow remains in place.
