.SHORT TERM AND LONG TERM...
(This Evening through next Friday)
Issued at 254 PM EDT Sat Sep 12 2026

While not as robust as yesterday, additional shortwave energy aloft
today is aiding scattered to widespread showers and thunderstorms,
with gusty winds and heavy rainfall. Tonight, the low-level moist
air mass and a tendency for skies to clear is expected to result in
patchy fog Sunday morning over the inland areas.

Shower and storm coverage will increase again early Sunday morning
closer to the coast (albeit less coverage compared to previous
days), then move inland into the FL Counties by the afternoon, with
activity more seabreeze driven. Isolated to scattered showers and
storms possible again on Monday and Tuesday, mainly south of I-10.
Stronger storms will be capable of gusty winds, frequent lightning,
and locally heavy rainfall.

Anomalous ridge aloft will maximize early next week. The combination
of highs in the mid-90s and dew points in the mid-70s yields a low
to medium chance of dangerous heat index values exceeding 107 deg on
Sunday, Monday, and Tuesday, mainly over the Florida counties.
Otherwise, moderate heat-related impacts are expected each day, with
heat index values generally reaching the 98-106 degree range each
afternoon.

Wednesday is looking to be the driest day of the week, with dew
points falling into the 60s away from the Gulf Coast. Despite highs
in the upper 80s to lower 90s, the drier air will begin to alleviate
heat concerns. Increased easterly flow will gradually moisten the
air mass, with a higher chance of showers and storms by Friday.

.AVIATION...
(00Z TAFS)
Issued at 722 PM EDT Sat Sep 12 2026

Small band of showers continues to move through southwestern
Georgia this evening and may clip KABY between now and 01Z.
Otherwise VFR conditions are expected this evening. Patchy fog
and/or low stratus are a concern, especially for KDHN, KABY, and
KVLD, later tonight into early Sunday morning where MVFR-IFR
ceilings/visibilities appear likely. Improvement is expected by
around 14Z. A few showers are forecast over the Gulf early Sunday
morning and may approach KECP in and around sunrise, which has
prompted the PROB30 there. Another couple of showers and storms
are forecast, mainly along Florida`s seabreeze, or near KTLH,
Sunday afternoon, but coverage is not expected to be as widespread
as it was today. Confidence in rain/storms impacting KDHN, KABY,
and KVLD is too low for Sunday afternoon to include in the TAFs at
this time.

.MARINE...
Issued at 254 PM EDT Sat Sep 12 2026

With high pressure progged just to the west of the waters on Sunday
and Monday, winds tend to become West-Northwest, except onshore
in the seabreeze zone during the afternoon and evening. Scattered
showers and thunderstorms expected to be centered again on Sunday
morning with briefly higher winds and seas possible. Waterspouts
cannot be ruled out. A notable decrease in the coverage of showers
and storms early next week. Strong high pressure nosing down the
Eastern Seaboard will favor moderate easterly breezes Tuesday,
which will become fresh Tuesday Night into Wednesday. There is a
low to medium chance of meeting or exceeding advisory level winds
Wednesday and Thursday.

.FIRE WEATHER...
Issued at 254 PM EDT Sat Sep 12 2026

Scattered to numerous showers and thunderstorms are expected across
much of the region on Saturday, with the greatest coverage shifting
to the FL districts on Sunday, before a notable decrease forecast on
Monday. Storms will come with sudden gusty winds, frequent lightning
and brief torrential downpours. Southerly transport winds Saturday
become Westerly on Sunday. On Saturday, the light nature of the
transport winds combined with modest mixing heights will lead to
pockets of poor dispersion across the Florida districts that will
persist through the afternoon. The heat index will be in the 98-107
degree range through early next week. Dangerous heat indices above
107 degrees are possible Sunday into early next week mainly across
the FL districts.

.HYDROLOGY...
Issued at 254 PM EDT Sat Sep 12 2026

The focus for scattered showers and storms will shift to the Florida
Counties on Sunday. Much of the upcoming week will feature more
isolated storm coverage generally south of I-10 and the Florida Big
Bend. While the combination of locally heavy rainfall and slow
moving storms may lead to minor urban and poor drainage flooding,
widespread flooding and river flooding is not expected through the
period.
