.NEAR TERM /THROUGH TONIGHT/...
After a cool start especially away from the coast, a very
similar pattern to the previous few days is expected across the
region today as the area remains under the influence of high
pressure ridging from the north and east. The main difference will
be the fact that the high pressure center will start to slowly drift
southeastward off the coast of the Carolinas throughout the day
today and through tonight, which will veer winds more east to
southeasterly as compared to a northeast flow. In addition, higher
clouds will start to move into the region throughout the day today,
especially north and west. Despite more cloud cover for many, the
veering winds as well as ridging building a bit aloft will allow for
high temps a few degrees higher today, especially away from the
coast where widespread 70s are expected and perhaps a few readings
at 80 near the Suwannee River Valley. Further north and east and
towards the coast, we will still hang on to the 60s for the most
part.

Tonight, higher clouds will start to thicken as low pressure and
associated frontal system start to approach the area from the
northwest. Expecting the area to remain dry through early Sunday
Morning at this time, though a warm front lifting northeast
overnight Sunday may bring a few isolated showers with it. Min temps
will be milder accordingly, with readings in the 50s being most
common.

&&

.SHORT TERM /SUNDAY THROUGH MONDAY NIGHT/...
On Sunday, a positive tilt mid to upper level trough will swing
through the eastern U.S. with a sfc low around 1000-1004 mb moving
across the southern U.S. A strong cold front will be moving quickly
eastward from the lower MS valley east to our local area by the late
evening. The forecast area will be in the warm sector on Sunday with
breezy and warm conditions ahead of the front. Breezy/windy
southerly winds of 15-25 mph gusting to near 40 mph are anticipated,
with a possible need for a wind advisory, for gusts near the 40-45
mph range. A good swath of moisture moves out ahead and the cold
front with instability reaching upwards of 300-500 J and bulk shear
of about 50 kt. CAM model guidance shows the main squall line
approaching the area, moving into western zones by about the 1-4 pm
time frame but some prefrontal scattered convection may also develop
ahead of this feature. The line should continue to move east,
possibly merging with prefrontal convection by late aftn, with
potentially for a few damaging wind gusts and an isolated embedded
tornado within the line. Latest HRRR shows some indications of this
isolated tornado threat from inland northeast FL to parts of inland
southeast GA. Sunday night, the weakening squall line looks to be
located roughly from near the GA nearshore waters southwest to
northeast FL, continuing to move east. However, timing of the line
still a little in question given the differences between HRRR and
other guidance. While the threat is still there for a severe storm,
the threat should be waning Sunday night after about 8-9 PM as the
airmass stabilizes overnight and front moves in from the west. SPC
has highlighted the forecast area in a marginal to slight risk of
severe storms. The front should push into the area Sunday night
while the associated sfc low moves offshore of the southeast coast.
Precip chances should diminish considerably overnight and lows will
drop to the 50s.

On Monday, post-frontal trough extends from the low offshore and
across our area and so we continue to have a chance of showers in
the morning, but would assume the chances will diminish further in
the aftn. Northwest to north winds and drier conditions will make
for a more pleasant day with highs in the lower 70s south zones to
60s coast and nrn zones as weak cold advection is anticipated behind
the departing system. Not too cold on Monday night with lows in the
40s for nrn zones and lower 50s further south. Some patchy fog can`t
be ruled out.

&&

.LONG TERM /TUESDAY THROUGH FRIDAY/...
Surface high pressure system around 1025 mb will be positioned over
the SC/NC coast Tuesday morning and will move southward through mid
to late week and so return flow will develop eventually by mid week.
Airmass looks dry for the long term but the model blend shows some
low chance for showers on Friday but confidence at this point
remains low given the low amount of QPF in the output and what looks
like weak forcing aloft. The return flow suggests moderation in high
temps and then above normal temps with high of around 80 and then
lower 80s by Thursday into Friday. Overall, lows will be above
average during the long term. The pattern may favor some occasional
late night and early morning fog/stratus.

&&

.AVIATION /12Z SATURDAY THROUGH 12Z SUNDAY/...
VFR conditions are expected to persist today and into later tonight.
FEW to SCT cumulus expected to develop in the afternoon as mean
layer low-level flow through 5 kft turns east and then southeast
with a moisture increase. Some chance of MVFR late tonight, but
confidence is on the low side. Very isolated showers/sprinkles
will also be possible towards the end of the forecast period,
though coverage/impacts expected to be very minimal.

&&

.MARINE...


High pressure ridging persists through today, with the high center
drifting towards east of the region by tonight. A warm front will
lift northward across the area tonight as a low pressure system
approaches from the west. Isolated shower and thunderstorm chances
will increase tonight over area waters, but especially through
Sunday as the low and associated cold front move across the region
through Sunday Night. A few storms may be strong to severe Sunday
afternoon and Evening as a squall line moves across the region.
South-southwesterly winds also increase ahead of the front on
Sunday, with  small craft advisory conditions likely for all waters
Sunday Afternoon/Evening and persisting offshore Sunday Night. High
pressure ridging will then build back down the southeastern coast on
Tuesday before weakening and shifting east of the Florida Peninsula
once again mid week.

Rip Currents: Moderate rip current risk today for all beaches with a
persistent onshore flow. Stronger more southerly winds along shore
Sunday will persist a moderate rip current risk for the end of the
weekend.

.FIRE WEATHER...

- CRITICALLY LOW HUMIDITY ACROSS INLAND SOUTHEAST GEORGIA THIS
  AFTERNOON
- HIGH DAYTIME DISPERSIONS ON SUNDAY...

Long durations of critically low relative humidity values are
forecast this afternoon for inland portions of southeast Georgia.
However, low-level moisture gradually increases tonight and
early Sunday morning as a cold front approaches.

Increasing cloud cover is expected later tonight into Sunday ahead
of cold front, with high chances for showers and embedded
thunderstorms, some of which could be strong or briefly severe. This
activity will overspread the area Sunday, possibly continuing into
late Sunday night. Strong transport winds, breezy surface speeds,
and elevated mixing heights will create high daytime dispersion
values on Sunday throughout most of the area. Beneficial rainfall
overspreads the region Sunday into Monday. Rainfall amounts of
around 1 inch are possible, with locally higher totals possible.
Linger shower chances on Monday but will decrease in the afternoon
as drier air will filter in.

FOG POTENTIAL AND OTHER REMARKS: Significant fog formation is not
expected during the next several days but some localized visibility
reductions are possible during the predawn and early morning hours
for locations near active or ongoing wildfires or prescribed burns.
