.SHORT TERM...
(Today through Friday)
Issued at 103 AM EDT Thu Mar 13 2025

A quiet weather regime will persist for South Florida today as the
combination of surface ridging and a persistent sub-tropical jet
aloft will keep the bulk of synoptic activity away from the region.
Aloft, a plume of weak mid-level vorticity will advect eastward
along the subtropical jet-stream arriving across South Florida
during the afternoon and evening hours. At the surface, The
advection of the surface ridge axis to the east of the region over
the western Atlantic waters will result in light and variable winds
across the region today with mesoscale processes (the Atlantic and
Gulf sea-breeze in full swing. Winds will veer onshore and enhance
along both coasts during the afternoon hours resulting in high
temperatures ranging from the upper 70s along both coasts to
temperatures in the low 80s across most of SoFlo`s inland locales.
With the gradual moderation of the airmass over South Florida,
increasing low-level boundary moisture will allow for more some
shallow cloud development across the region, particularly during the
afternoon hours. In fact, some of the mesoscale models depict
isolated to scattered shower activity across the east coast metro
areas this afternoon as the sea-breeze boundary interacts with good
diurnal heating. Given the dry air aloft, any shower activity will
be shallow in nature as instability remains meager.

With the loss of surface heating, the atmosphere will decouple and
stratify resulting in light and variable winds overnight. This will
result in another comfortable night across the region with forecast
lows several degrees warmer in the mid 50s inland with low temps in
the low to mid 60s along the east coast. Given light winds and an
increase in surface moisture, patchy fog will be a possibility on
Friday morning.

Rinse and repeat pattern on Friday as temperatures continue the
upward trend as the airmass continues to moderate. Sea-breeze
circulations will once again veer winds onshore during the afternoon
hours resulting in forecasted high temperatures in the low 80s along
both coasts with temps in the middle to upper 80s expected inland.

.LONG TERM...
(Friday night through Wednesday)
Issued at 103 AM EDT Thu Mar 13 2025

As the subtropical jet-stream begins to retrograde to the north of
the region, stout mid-level ridging will develop over the Gulf and
South Florida during the first half of the upcoming weekend. At the
surface, winds will remain out of a persistent southeasterly
direction and enhance in response to a developing gradient between
surface ridging and a low pressure system over the western Gulf. The
combination of mid-level subsidence and enhanced onshore flow will
reinforce and accelerate the ongoing warming trend. The
aforementioned mid-level subsidence will prevent any notable rain
chances across the region which will result in efficient diurnal
heating. Given the southeasterly flow regime, a temperature gradient
is forecast across the region with forecasted high temps in the low
to mid 80s on the east coast of SoFlo on Saturday with highs in the
mid to upper 80s forecast for most inland locations. These
forecasted high temperatures are several degrees above average for
this time of year. Some model guidance even hints at potential high
temperatures in the lower 90s across inland Collier, Glades, and
Hendry counties on Saturday afternoon.

As surface winds veer to a southerly then southwesterly direction
during the day on Sunday, the heat really does turn up. After a warm
start to the day for this time of year (The Euro`s Extreme Forecast
Index (EFI) depicts anomalous overnight temps) with daybreak temps
in the upper 60s to mid 70s; temperatures will climb into the low
80s along the gulf coast, mid to upper 80s along the east coast, and
the lower 90s across most of inland South Florida. Apparent
temperatures values (feels-like temperatures) are forecast to be in
the mid 90s with muggy and humid conditions. Given the unseasonable
heat for this time of year, individuals who will be outdoors should
take precautions to remain hydrated and take frequent breaks to
prevent any heat related illnesses. The official climate sites may
come within a few degrees of the record high temps for the date.

As a mid-level trough advects eastward over the southeastern United
States, a surface low will accelerate northeastward away from the
Gulf. An attendant surface boundary attached to the low will sweep
eastward across the Gulf and move across South Florida on Sunday
night. With the passage of the front overnight, instability should
be fairly limited. However, given a relatively deeper plume of
moisture along the frontal boundary, a line of broken shower
activity cannot be ruled out during the overnight hours of Sunday
into Monday morning with minimal rainfall accumulations.

Temperatures will return to seasonable norms on Monday as highs
remain in the mid to upper 70s area-wide with the exception of
temperatures in the low 80s across the southern extent of the
region. Northerly winds will enhance on Monday night into Tuesday as
a pressure gradient develops, resulting in a cool and comfortable
start on Tuesday with forecasted low temps in the 50s and 60s. For
the remainder of the week, winds will slowly veer back to an
easterly direction and a gradual warming trend will commence once
again.

.AVIATION...
(06Z TAFS)
Issued at 103 AM EDT Thu Mar 13 2025

Mainly VFR conditions will prevail through the 06Z TAF period.
Winds will remain light and variable early this morning.
East/southeasterly flow picks up again around 16-18Z with winds
around 10 kts, with a Gulf breeze at the KAPF TAF site between
17-19z. SCT showers are possible late this afternoon across the
east coast metro.

&&

.MARINE...
Issued at 103 AM EDT Thu Mar 13 2025

Boating conditions will remain benign as winds remain light and
variable for the remainder of the week and seas lessen. Another
frontal boundary approach early next week is forecast to result in
enhanced winds and seas beginning during the upcoming weekend.

&&

.BEACHES...
Issued at 103 AM EDT Thu Mar 13 2025

The risk of rip currents will remain elevated for portions of the
Atlantic coastline for the duration of the week as onshore flow
develops. The highest risk of rip currents during this time frame
will be across the Palm Beach county beaches.
