.SHORT TERM...
(Today through Thursday)
Issued at 1258 AM EST Wed Dec 4 2024

Mesoanalysis this morning indicates that the potent positively tilted
shortwave has propagated into the western Atlantic waters while the
expansive trailing ridge of surface high pressure remains situated
across the southeastern United States at the foothills of the
Appalachian Mountains. From a climatological standpoint, this setup
is a classic harbinger of a hyperborean (cold) morning across the
region. This will allow for one last morning of continued anticyclonic
circulation of surface ridging to support northerly peninsular flow
across the region and continued cold air advection (CAA). The coldest
temps and feels-like temps will once again be observed to the west of
Lake Okeechobee this morning with a northwest to southeast temperature
and dew point gradient remaining in place. Actual minimum temperatures
will range from the upper 30s to low 40s across interior Hendry and
Glades counties, low to mid 40s across coastal Collier, and lows in the
low 50s along the east coast metro areas. Although the pressure gradient
has relaxed compared to previous days, apparent (feels-like)
temperatures will certainly be felt across the area this morning as wind
chills will range from the mid to upper 30s across the interior of
Hendry, Glades, and Collier counties. Across coastal Collier and
portions of inland Palm Beach, feels-like temps  in the mid to upper
40s can be expected with feels-like temperatures near 50 expected
elsewhere across the east coast metro.

With the previous 500mb shortwave/lobe of troughing advecting eastward
into the western Atlantic waters by late Wednesday, the subtropical
jet-stream will take a more zonal (west to east) orientation across
the region. Both the GEFS and EPS indicate the next short-wave/lobe
remaining a little further north, keeping the best dynamics closer to
its trajectory over the Great Lakes, northeastern United States, and
mid-Atlantic. Synoptic changes aloft dictate what occurs at the surface
and the anomalous heights (strong surface high pressure) currently over
the southeastern United States will advect offshore on Thursday into
the western Atlantic as well. This subtle but key move will switch our
prevailing surface flow from a northerly direction to a northeasterly
direction. This will begin the gradual moderating trend on Thursday
with high temperatures across the region a few degrees warmer than
Wednesday and a continued moderation of temperatures during the
overnight hours.

.LONG TERM...
(Thursday night through Tuesday)
Issued at 1258 AM EST Wed Dec 4 2024

After a prolonged period of east coast troughing, mid-level ridging
will begin to build across the region during the end of the work week
as surface winds remain out of a northeasterly direction. Expect a
gradual climb in both low and high temperatures as the work week leads
into the weekend as well as a gradual moistening of dew points across
the region. Model solutions have backed off on the previous solution of
having this next frontal boundary arrive in South Florida with any
noteworthy temperature implications. Instead, any frontal boundary
passage will be meager in nature with winds quickly swinging out of
a northeasterly direction. The lack of moisture and synoptic support
aloft will keep rain chances to a minimum across the region acting to
extend the long period of dry weather South Florida has experienced in
the recent past.  High temps will range from the mid to upper 70s
through the weekend, before increasing to the low to mid 80s early next
week. Overnight lows will generally be in the mid 50s to low 60s through
the weekend, increasing to the low 60s inland and near 70 along the coast,
early next week.

.AVIATION...
(06Z TAFS)
Issued at 1201 AM EST Wed Dec 4 2024

VFR through the 06Z TAF period. Mainly clear skies expected with
NNW winds 5-10 kts becoming NE after 17Z. APF expected to have NE
winds through the entire period.

&&

.MARINE...
Issued at 1258 AM EST Wed Dec 4 2024

As high pressure gradually shifts into the western Atlantic today, winds
across all local waters will gradually diminish and seas across the
Atlantic waters will subside. Another frontal boundary may approach the
local waters towards the end of the week and into the upcoming weekend,
which may cause winds and seas to increase during this time frame.

&&

.BEACHES...
Issued at 1258 AM EST Wed Dec 4 2024

A high risk of rip currents will continue across the Atlantic Coast beaches
today. An elevated risk will remain along the Palm Beaches late
this week due to a lingering NE swell.
