.NEAR TERM...
(Through Tonight)
Issued at 1135 PM EDT Thu May 9 2024

Watching two areas of convection at the moment, one across central
Alabama and one further west into central/southern Mississippi and
will gradually enter western Alabama. Outflow from earlier storms
runs north of Apalachicola northwest into central Alabama. Dewpoints
east of this boundary in the low to mid 60s and dewpoints west
are in the mid 70s. MLCAPE in the area runs from 1000-2000 J/kg
with higher readings further west. Some inhibition east of the
outflow and much less further west. The outflow boundary is
expected to slowly move back north and east overnight as a mid
level disturbance approaches and southerly winds become more
dominant ahead of this feature.

Assessing the latest CAMs, convection over central Alabama will
drift southeast and into our northern counties before 1AM. Some
questions on how far south this convection can go into our area
before significantly weakening as the atmosphere east of the
outflow boundary is more stable. Additional convection may fire
into the panhandle in that same timeframe while convection in
southern Mississippi/western Alabama races towards the area
towards 5AM. These two areas congeal through the night while
convection in Texas races along the Gulf coast towards the area in
the morning hours.

The enhanced risk from SPC remains overnight with destructive winds
70-80+ mph along with tornadoes and large hail. Residents are urged
to have several ways to receive warnings, and make sure these
devices and means are charged and the volume is up loud as much
of this will be occurring at night. These systems have the
potential to produce widespread damage along its track.

Appears the MCS will push through the area in the morning hours,
trends continue to show residual showers and storms develop into the
afternoon hours. Flooding may become an issue depending on how the
MCS evolves and moves across the area and convection that develops
behind the it. Keep pops going further west into the afternoon hours
and may have to expand if convection does develop further west into
the panhandle.

Pops will be winding down Friday night as a cold front moves
through. Highs will be in the 80s today and lows tonight will fall
in the low 60s. Dewpoints fall into the mid 50s behind the front so
it will feel like a crisp morning into Saturday morning.

.SHORT TERM...
(Saturday through Sunday Night)
Issued at 225 PM EDT Thu May 9 2024

No weather concerns during this time frame for any severe weather
recovery efforts. No precipitation is expected on Saturday and
Sunday with a cooler and drier air mass compared to earlier in the
week. It will be mostly sunny on Saturday with an increase in
mid and high level cloudiness on Sunday. Highs both days in the low
to mid-80s and lows in the upper 50s to lower 60s. Much lower dew
points will make for a comfortable air mass this weekend. Winds
will generally be around 10 mph.

&&

.LONG TERM...
(Monday through Wednesday)
Issued at 225 PM EDT Thu May 9 2024

On Monday another shortwave looks to move across the northern Gulf
states with our region possibly being impacted on Tuesday as winds
turn to being southeasterly. With this shortwave possibly moving
overhead, a stationary boundary to our south, left behind from the
previous system, and a low-level wind field again around 30-45 kts,
the potential for severe is once again present. We'll have to see
how this progresses over the next few days to have better
confidence, be sure to come back for updates.

Expect relatively cooler temps to what we've been experiencing as of
late. Daytime highs will generally be in the low to mid 80s with
overnight lows generally in the upper 50s to mid 60s until Tuesday
morning. Beyond Tuesday morning, overnight lows look to rebound into
the mid and upper 60s.

.AVIATION...
(06Z TAFS)
Issued at 131 AM EDT Fri May 10 2024

Clusters of storms are currently moving through southwest Georgia
with a more intense line moving into southern Alabama. This area
will move eastward and pose a damaging wind threat, along with
some hail and isolated tornadoes. Kept the timing of TSRA and
strong wind gusts as is from the previous TAFs and will amend as
needed. Cigs will lower to MVFR/IFR overnight with vsby
restrictions primarily underneath heavier convection. All and all,
poor flying conditions through the afternoon hours until the
convection passes to the east.

.MARINE...
Issued at 225 PM EDT Thu May 9 2024

An Atlantic ridge axis across the southern Florida Peninsula will
retreat southward tonight. A cold front will slowly approach from
the north on Friday, preceded by strong to severe thunderstorms over
the waters. Cautionary conditions could be possible Friday. The
front will limp across the waters on Friday night. It will be
followed by moderate to occasionally fresh northerly breezes on
Saturday morning. Surface high pressure over the southern Plains on
Saturday will move across the Southeast States on Sunday, causing
winds to clock around. High pressure will move east into the
Atlantic on Monday, brining a return to south-southeasterly flow.

.FIRE WEATHER...
Issued at 225 PM EDT Thu May 9 2024

Multiple rounds of wetting rains and severe thunderstorms are
expected this afternoon through Friday morning. The first round is
this afternoon through the evening hours where all modes of severe
weather are possible. Outside of storms, high dispersions are still
likely for the rest of this afternoon for areas along the I-10/I-75
Corridor in the FL Big Bend.

The second round of storms is expected during the morning hours on
Friday. By the afternoon, showers and thunderstorms are expected to
have cleared the CWA with fair dispersions behind the storms.
Elevated dispersions will be just behind the front, possibly
clipping our northwestern-most counties in SE Alabama Friday
afternoon. Fair to moderate dispersions are expected for the rest of
the period. Following Friday's cold front, winds will shift to be
northerly, with transwinds at about 10-15 mph. Temperatures will be
briefly cooler with MinRH in the mid-30s% to around 40%.

.HYDROLOGY...
Issued at 225 PM EDT Thu May 9 2024

A slight risk of excessive rainfall exists along and north of I-10
today and tonight (SE AL, SW GA, and portions of the FL counties),
with a marginal risk for most of the area on Friday as a frontal
system looks to push through the region. The primary risk here being
torrential downpours or training within any thunderstorm(s) leading
to a localized flash flooding risk. Otherwise, area rivers are
expected to remain below flood stage. In the extended period the WPC
is forecasting 3-5 inches by midweek next week. This could introduce
some riverine concerns, however, it's too far out to say with any
degree of confidence.
