.NEAR TERM...
(Today and tonight)
Issued at 317 AM EDT Tue Jun 25 2024

A weak cold front will drift south to near the Florida state line
this afternoon before stalling and pushed northward again by the sea
breeze. These boundaries and their collision will be the focus for
showers and thunderstorms to develop this afternoon, especially in
the Florida Big Bend. There is a good deal of mid-level dry air that
storms will have to overcome, but this does two things. It may limit
the number of storms we see, but the storms that do develop will
have the potential to be strong. Given this environment, strong to
severe downburst winds are possible. DCAPE is anywhere from 1200-
1600 J/kg on various forecast soundings, and SBCAPE is 2500-4000
J/kg. Thus, while not everyone will see storms today, the storms
that do develop could pack a wallop.

The other story is the heat. Behind the front, drier air will mix
down, leading to hot, but not oppressively humid weather this
afternoon. Dew points will fall into the 60s in these areas. South
of I-10, and south of the developing sea breeze, the oppressively
muggy air remains in place, making for another sweltering day. Dew
points here will be in the mid to upper 70s. This combined with
temperatures well into the 90s to near 100 will result in dangerous
heat index values of 108-112 across the southern half of the area,
where a Heat Advisory is in effect. Lows tonight won`t offer much
heat relief with mid-70s to lower 80s area-wide.

For those that are working or playing outside, take frequent breaks
in air conditioning and stay hydrated. This level of heat is
dangerous if you don`t take precautions. Know the signs of heat
illnesses. And if you hear thunder today, remember "When Thunder
Roars, Go Indoors!"

.SHORT TERM & LONG TERM...
(Wednesday through Monday)
Issued at 317 AM EDT Tue Jun 25 2024

A more unsettled pattern is expected for much of the next week
with the mid level ridge retreating westward and troughing in
place Wednesday through the end of the week. This will allow
shower and thunderstorm chances to increase to scattered to
widespread each day with gusty winds and locally heavy rainfall
the primary threats. Also as a result, high temps are forecast to
lower into the low to mid 90s range Thursday through Saturday.
Over the weekend, the mid level ridge begins to build back into
the area, raising temperatures again into the mid to upper 90s and
limiting daily shower and thunderstorm chances just a bit into
early next week.

.MARINE...
Issued at 317 AM EDT Tue Jun 25 2024

West to southwest winds generally less than 15 knots are expected
through the period. Seas will generally be between 1 to 3 feet,
with the 3 foot waves being favored west of Apalachicola. Long
period swells will continue today before dropping to around 4 to 5
seconds by Wednesday. Nightly chances of showers and storms will
be possible over the waters with the highest chances east of

.FIRE WEATHER...
Issued at 317 AM EDT Tue Jun 25 2024

Generally west to southwest transport winds around 10 to 15 mph and
very high mixing heights will lead to good to excellent dispersions
the next few afternoons. Dispersions will be highest across the
Alabama and Georgia zones Wednesday, then across the Georgia zones
and near the Suwannee Valley on Thursday. Minimum RH values will
fall into the upper 20s across the far northern zones with 30s and
40s elsewhere.

Scattered thunderstorms will develop this afternoon near I-10 and
drift southward. These storms today could produce strong, gusty,
erratic winds in and near the storms. Rain chances increase further
for Wednesday and Thursday area-wide.

.HYDROLOGY...
Issued at 358 PM EDT Mon Jun 24 2024

Diurnal pop-up thunderstorms could lead to localized flooding
concerns where slow moving storms could produce several inches of
rainfall. Otherwise, there are currently no river flooding
concerns.
