.NEAR TERM...
(Today and tonight)
Issued at 353 AM EDT Fri May 10 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 353 AM EDT Fri May 10 2024

Being post-frontal will lead to relatively cooler temps and a 
decrease in moisture as northerly flow prevails throughout the short 
term. Although surface winds will be southerly near the coast during 
the afternoon hours due to the sea breeze, high pressure will lead 
to large-scale subsidence. Limiting development to fair weather Cu 
or developing towers that fizzle away. Overall, a nice weekend is on 
tap.

Expect daytime highs generally in the 80s with overnight lows 
generally in the upper 50s to low 60s.

.LONG TERM...
(Monday through Thursday)
Issued at 353 AM EDT Fri May 10 2024

Next week a parade of shortwaves looks to move across the north Gulf 
states with several rounds of weather possible. Given upper-level 
support and good instability and decent low-level shear there's a 
fair chance for multiple rounds of severe weather. Given the 
mesoscale nature of these disturbances it's far too early to get 
into specifics, however, once we get into Tuesday and beyond we're 
looking at an active period.

Expect daytime highs initially in the upper 70s to mid 80s on Monday 
to climb back up into the upper 80s to low 90s by Thursday. 
Similarly, expect overnight lows initially in the low to mid 60s 
initially climb into the upper 60s to lower 70s by Thursday.

.AVIATION...
(12Z TAFS)
Issued at 635 AM EDT Fri May 10 2024

QLCS line has passed DHN/ECP/ABY and is bearing down on TLH and
VLD through 12Z. Expect damaging winds to possibly accompany the
line and have it in the TAFs. Once the line goes through, expect
several hours of SHRA and VCTS but should decrease later today.
Some CAMs show additional development along the coast which would
affect ECP/TLH through the morning so may have to amend to keep
TSRA longer at these locations. Winds will eventually veer to the
northwest with time as the rain moves out. Degraded flight
conditions as would be expected will gradually improve later
today.

.MARINE...
Issued at 353 AM EDT Fri May 10 2024

A cold front will slowly approach from the northwest today, preceded 
by strong to severe thunderstorms over the waters. Cautionary 
conditions could be possible throughout today into tomorrow morning. 
The front will limp across the waters on tonight. 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 southerly flow.

.FIRE WEATHER...
Issued at 353 AM EDT Fri May 10 2024

Through early this afternoon, thunderstorms are expected to increase 
in coverage and intensity as a complex of storms moves through the 
region. Severe storms including destructive winds, hail, and 
isolated tornadoes will all be possible. By late afternoon or early 
evening, the rain will move east of the Florida Big Bend with drying 
conditions into the weekend. The weather pattern will remain 
unsettled into next week with several rounds of wetting rains and 
possible severe weather.

.HYDROLOGY...
Issued at 353 AM EDT Fri May 10 2024

A marginal risk of excessive rainfall is place today for most of the 
area 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.
