...New UPDATE...

.UPDATE...
Issued at 811 PM EDT Tue Apr 30 2024

PoPs were increased across portions of the western Florida Big
Bend this evening, where some persistent showers and thunderstorms
have developed. These showers and thunderstorms should diminish in
the next 1-2 hours. Outside of this change, there were no other
updates needed at this time.

.NEAR TERM...
(Through Wednesday)
Issued at 349 PM EDT Tue Apr 30 2024

The forecast is on track this afternoon as an upper level shortwave
swings through the region. This has brought isolated to scattered
showers and thunderstorms to SE AL and the W FL Panhandle so far
today, with the line of storms pushing to the east and southeast.
Model guidance has been all over the board with what will happen,
though this line should continue its track toward the Gulf.
Elsewhere, the guidance varies leaving confidence low. Opted to keep
the shower and thunderstorm potential to about 15-30% for SW GA and
the W FL Big Bend should any should any other storms try to pop up.
If not, skies should gradually clear leaving us with the overnight
forecast of fog and stratus. Tweaked the fog for SW GA and the E FL
Big Bend to capture more of a patchy fog threat rather than areas of
fog as confidence was lower for widespread fog development. This may
need to be reverted back depending on what the next set of guidance
is. Elsewhere areas of fog was kept for SE AL, the FL Panhandle, and
W FL Big Bend. Dense fog could develop in this region, but
confidence is too low at this time to hoist any sort of advisory.
Any fog or stratus that does develop should dissipate within a few
hours of sunrise. Then skies should clear leaving us with a mostly
dry day. Some CAMs suggest we could see some sea breeze type showers
and thunderstorms tomorrow, but again confidence was too low to
include at the forecast this time.

.SHORT TERM...
(Wednesday night through Thursday night)
Issued at 349 PM EDT Tue Apr 30 2024

An H5 ridge building over the Southeast will limit rain chances
through the short term period. There is just enough moisture that an
isolated shower or thunderstorm along the East Coast sea breeze that
will be pushing west Thursday afternoon. Confidence wasn`t too high
to get it much west of I-75, but it`s something to monitor on
Thursday. Otherwise, temperatures Wednesday and Thursday nights will
generally be in the middle 60s with highs Thursday in and around 90.
It`s also worth mentioning that fog is possible each night thanks to
the proximity of the surface high and ample low-level moisture.

.LONG TERM...
(Friday through Monday)
Issued at 349 PM EDT Tue Apr 30 2024

Warm and humid conditions are expected the first weekend of May with
daytime highs hanging out in the upper 80s to lower 90s and
overnight lows in the middle 60s. A series of H5 shortwaves are
forecast to move through the Southeast, which will increase
afternoon rain chances through much of the period. The strongest
shortwave is forecast to swing through Saturday and is when rain
chances are highest along and north of I-10. Shower and thunderstorm
chances linger Sunday afternoon before drier air takes over early
next week as ridging develops over the Southeast.

.AVIATION...
(00Z TAFS)
Issued at 715 PM EDT Tue Apr 30 2024

Showers and thunderstorms may be ongoing at the start of this TAF
period for the VLD terminal. Reduced vsbys are likely if caught
in the heavier rain but, should soon end around 00z-01z. During
the overnight hours, fog will develop and affect all terminals,
but can be dense for ECP, DHN, and TLH terminals. The timing for
the lowest vsbys are expected between 09-12z for all terminals;
where 1/2SM vsbys are expected, although 1/4SM will be possible
but confidence is low at this time. Fog will begin lifting by
13-14z and should be VFR conditions soon after. Expect clearing
skies for the afternoon with westerly and northwesterly winds. ECP
will have southwesterly winds during the afternoon as a result of
the seabreeze.

Issued at 349 PM EDT Tue Apr 30 2024

A few showers and thunderstorms remain possible through the

High pressure takes over the northeastern Gulf of Mexico the rest of

are expected with seas generally 2 feet or less into the weekend.
