.NEAR TERM...
(Today and tonight)
Issued at 241 AM EDT Fri Jun 7 2024

A lingering cold front draped across the Florida Panhandle and Big
Bend today will provide a small focus for showers and thunderstorms
to develop along during the afternoon hours. The best chances will
likely be where the diurnal sea-breeze and this front collide during
the afternoon. While PoP chances will be at their highest across the
Florida Big Bend, they will be near climatological values, which is
roughly 30-40% for this time of the year. Some of these storms could
produce strong gusty winds, and some minor nuisance flooding. With
the front passing through most of the region on Thursday, drier air
has started to push into the region, which will lead to deep mixing
across the region. This deep mixing will lead to high temperatures
climbing into the mid to upper 90s across the region. Fortunately,
lower dewpoints in the low to mid 60s are expected to coincide with
the deep layer mixing, which will prevent heat index values from
climbing much beyond the 95 to the low 100s. With the drier air
continuing to advect into the region Friday night, overnight lows
will be able to fall into the mid 60s across SE Alabama and SW
Georgia, and the low 70s across the Florida Panhandle and Big Bend.

.SHORT TERM...
(Saturday through Sunday night)
Issued at 241 AM EDT Fri Jun 7 2024

Hot temperatures from Friday are expected to continue into the
weekend as the center of an upper level ridge approaches the tri-
state region from the west. We`ll likely see the hottest
temperatures of season so far as we climb into the upper 90s on
Saturday and Sunday. While the lack of significant humidity will
keep the dangerous heat away, temps will still be above average
with heat indices likely in the low 100s. With the upper level
ridge overhead, no rain is expected this weekend.

&&

.LONG TERM...
(Monday through Thursday)
Issued at 241 AM EDT Fri Jun 7 2024

The long term period will see a transition to wetter pattern but
the main uncertainty in the longer term is just how wet things
we`ll be. The week starts out with the upper level ridge weakening
as a broad upper level trough moves through the southern states.
This should help bring a weakening frontal boundary into the area
on Monday. Whether we squeeze out any rain will largely depend on
how quickly we can return the deep-layer moisture across the area.
Most ensemble guidance keeps conditions fairly dry Monday so POPs
were lowered on Monday compared to what the NBM gave us, but it
was noted that there are some wetter ensemble members in the GEPS
solutions where deep layer moisture streams quickly back so did
not stray too much drier from the NBM.

From Tuesday onwards, attention begins to turn to the south as the
area potentially sees a notable increase in deep-layer moisture
as winds become southerly and a moist tropical airmass advects
northwards into the Gulf. Whether this moist airmass sticks around
into the remainder of the week largely depends on how progressive
the upper level pattern across the CONUS is. The more progressive
GEFS solutions shunt tropical moisture off to the east while the
more amplified Euro ensembles would likely mean a slower
transition and eastward displacement of the rich tropical moisture
moving in from the south. Regardless, confidence is high in a
return to a few days of wet conditions, but uncertainty in whether
this sticks around into the end of the week and next week is
still large.

Accordingly, temperatures generally follow in inverse order to
rain chances. High temperatures in the upper 90s on Monday with
dry conditions cool off into the low to mid 90s by week`s end as
rain chances climb.

.MARINE...
Issued at 1007 AM EDT Fri Jun 7 2024

Offshore buoys were reporting light winds below 10 kts with 1-2-ft
seas and a dominant period of 5-6 seconds late this morning.

From CWF Synopsis...Favorable boating conditions are expected
into the weekend with relatively light winds and no showers or
storms expected outside of isolated activity late this morning and
afternoon. Winds and seas will be highest today before decreases
to around 1 foot are expected this weekend. Shower and
thunderstorm chances increase early next week as well as southerly
winds as deep- tropical moisture begins to move in from the
south. Cautionary conditions are possible at some point early next
week.

&&

.FIRE WEATHER...
Issued at 241 AM EDT Fri Jun 7 2024

High dispersions north of I-10 today will be the largest fire
weather concern. Transport winds of around 10-15 mph out of the
northwest across SE Alabama and SW Georgia are the main reasons for
high dispersions today. For areas along and south of I-10, transport
winds will remain around 5-10 mph out of the west/northwest. With
deep mixing expected today, mixing heights will reach heights around
7000 to near 8000 feet today. Minimum RH values will likely only
fall into the upper 30s. Overall, there are minimal PoP chances
today, with the highest chances of (30-40%) being along coastal
Florida Big Bend zones where surface dewpoints will remain their
highest.

.HYDROLOGY...
Issued at 241 AM EDT Fri Jun 7 2024

Mostly dry weather is expected this weekend, followed by a wetter
patten developing sometime next week and possibly beyond into the
following weekend. It`s too early to speculate with rainfall
amounts and uncertainty remains rather large with regards to how
long deep-tropical moisture will stick around. In terms of rivers,
a few in the Suwannee basin remain in action stage but are on a
downward trend.
