.SHORT TERM...
(Today through Sunday)
Issued at 236 AM EDT Sat May 25 2024

Models show fair agreement regarding the overall scenario
for today. The persisting ridge over the area will briefly
erode as a shortwave trough feature migrates eastward into
the Atlantic seaboard. Thermodynamic parameters will become
a little more robust by this afternoon with SBCAPE values
around 1500 J/kg, while model PWATs around 2 inches depict
increasing moisture advection with the winds shifting S/SW.
But the key element for convection to get initiated will revolve
around the sea breeze boundaries, with the Atlantic sea breeze
driving thunderstorm activity early in the afternoon.

The overall flow pattern will favor shower/storm activity over
the east half of SoFlo with best chances late in the afternoon.
As the sea breeze boundaries begin marching inland, expect a few
storms to become strong, or even severe at times. The latest
convective outlook from the Storm Prediction Center has
placed the area under a marginal risk for severe storms today.
Main hazards will be strong damaging winds, large hail, lightning
strikes, and localized flooding.

Despite the increasing cloud cover and potential for convection,
model solutions remain stubborn in keeping afternoon high temps
in the low-mid 90s. Can`t even rule out a few interior spots in
the upper 90s.

For Sunday, models quickly push the aforementioned trough further
Into the western Atlantic, with a mid-level ridge building back
Across the peninsula. This will help in shifting flow back to the
SE, along with increasing drier mid-level air advection. However,
The Gulf coast should have a westerly sea breeze veering winds to
a more westerly flow in the afternoon. Convective activity will be
much less than Saturday, with mainly the Atlantic coast carrying
low-end POPs.

Expect the warming trend to continue on Sunday with afternoon highs
in the low-mid 90s, along with heat index values in the 105 range
over interior areas

.LONG TERM...
(Sunday night through Friday)
Issued at 236 AM EDT Sat May 25 2024

Models keep a mid-level ridge in place early next week, with drier
mid-level air and ridging keeping convection to a minimum through
the middle of the work week. Then global solutions show the mid-level
ridge eroding away as a deepening trough reaches the eastern CONUS.
An associated sfc frontal boundary will move southward and through
the Florida peninsula late Wednesday and Thursday. And although some
discrepancies remain in the global models, it seems that solutions
are trending towards pushing the boundary either near of just over
SoFlo. However, regardless of the final outcome, it should bring
an increase in moisture and instability, with better chances of
showers and storms for the end of the work week. Convection will
again be mainly driven by sea breezes each afternoon.

Expect high temperatures continue to hit the low-mid 90s across
the east coast metro areas and in the upper 90s over some interior
locations. Increasing moisture will also result in heat index values
in the 100 to 105 range, and localized areas rising above 105.

.AVIATION...
(06Z TAFS)
Issued at 125 AM EDT Sat May 25 2024

VFR conditions will prevail at the terminals through the morning
hours. Scattered thunderstorms can be expected mid-late afternoon
at the east coast terminals, with the peak window for impacts
generally from 19-02Z. Light and variable winds this morning will
trend SErly at the east coast sites (outside of thunderstorm
outflows) and westerly at KAPF this afternoon.

.MARINE...
Issued at 236 AM EDT Sat May 25 2024

Boating conditions will remain generally good today, then
southerly winds will become breezy and close to exercise
caution criteria on Sunday and Monday. Benign conditions
should return on Tuesday as winds shift to the SE and
decrease to around 10kt across the coastal waters.

.BEACHES...
Issued at 236 AM EDT Sat May 25 2024

The moderate risk of rip currents will become low at the Palm
beaches today, and remain low over the rest of the beaches through
the weekend and into early next week.
