.8AM UPDATE...
Areas of fog this morning, especially over portions of inland
northeast FL, will dissipate over the next hour or so. Otherwise,
forecast generally on track with slightly higher chances for showers
and isolated t`storms today with more moisture in place over the low
and mid levels. Best chances for convection, especially t`storms,
will be over far inland GA ahead of the approaching front as well as
towards the coast where the southwest Gulf breeze reaches the nearly
pinned Atlantic sea breeze this afternoon and evening. A very
isolated gusty microbrust in the 40-50 mph range cannot be ruled out
this afternoon and evening with some pockets of drier air lingering
aloft, but otherwise significant strong to severe storms are not
expected. Highs will be very warm today, generally in the mid to
upper 80s. Some areas could push 90+ depending on the extent of both
low and mid level clouds building in throughout the day today.

&&

.NEAR TERM /THROUGH TONIGHT/...
Main Highlights through Tonight:

- Isolated Thunderstorms Along the I-95 Corridor late this afternoon.

- High Risk of Rip Current Risk at the local Beaches This Weekend.

- Near Record Inland High Temperatures.

- Patchy inland fog possible for north-central FL early Monday.

Quiet conditions are expected to continue through the rest of the
early morning hours as southerly boundary layer winds keep
significant, dense fog from developing. Though dry and quiet over
land, convergence near the gulf stream is expected to generates
scattered showers well offshore through the morning.

As a cold front approaches today the prevailing steering flow will
shift southwesterly this today. That shift will push the gulf breeze
toward the Atlantic coast this afternoon which will be a focus for
widely scattered showers and a few thunderstorms along the I-95
corridor around 4-6 PM. In addition to the sea breeze merger
convection, showers and a few isolated storms may develop farther
inland across SE GA in the weakly unstable warm sector along a
prefrontal trough. Good mixing and southwesterly flow push afternoon
highs toward daily record territory again with widespread highs in
the upper 80s to 90 degrees.

Overall, confidence in extensive coverage of showers or strong
t`storms along the sea breeze merger is low given the lingering dry
air aloft, limited dynamics, and a marginal instability profile this
afternoon. Deeper moisture (PWAT above 1.5") will stay pooled along
the incoming front to the northwest and likely won`t reach the
forecast area in time to take advantage of the diurnal heating. Any
convective activity along the sea breeze merger will push off into
the Atlantic around sunset.

As afternoon storms move into the Atlantic, the cold front will push
into SE GA bringing a thicker cloud deck and elevated and remnant
showers along its edge. Enough elevated instability will be
available to keep the potential for widely scattered elevated
showers to develop with the fropa this evening before chances fade
by midnight. The front will slow it`s forward speed as it pushes
through the forecast area tonight and that may allow time for patchy
fog development across north-central FL early Monday morning. Lows
will dip back down into the upper 50s as drier/cooler arrives in SE
GA while thick cloud cover and the slowing front delay the cooler
air from arriving in NE FL until after sunrise Monday, so expect
lows somewhere in the low/mid 60s.

&&

.SHORT TERM /MONDAY THROUGH MONDAY NIGHT/...
Main Highlights This Period:

- Thunderstorm potential Monday and Tuesday

- Cooler with breezy onshore flow developing Monday

The cold front will be south of the area by Monday morning, then
stalling over central Florida as another front slowly approaches
from the north on Tuesday. Enough moisture will remain over the area
on Monday and Tuesday to prompt scattered to numerous showers mainly
over northeast Florida both days. Instability will be low due to
enhanced cloud cover and will limit numerous thunderstorm activity,
but cannot rule out a few storms each afternoon and evening.
Following the frontal passage, the local pressure gradient will
increase as high pressure sits to our northeast, bringing breezy
onshore winds through the week. Wind gusts Monday and Tuesday will
likely stay below Wind Advisory criteria, but gusts will approach 30-
35 mph near the immediate coast and St. Johns river basin areas.
After a hot weekend, temperatures will cool down Monday and Tuesday,
highs generally in the 70s.

&&

.LONG TERM /TUESDAY THROUGH SATURDAY/...
Main Highlights This Period:

-Strong onshore flow next week, with elevated winds along the coast
and inland locations

Strong onshore winds continue through the end of the week, with
gusts Wednesday and Thursday along the Atlantic coast approaching
Wind Advisory criteria (40 mph). Several days of gusty northeasterly
winds will create beach and marine hazards, with conditions
beginning to improve Saturday as the pressure gradient weakens. Rain
and isolated storm chances each day will primarily be over coastal
northeast Florida. Temperatures will be below normal Wednesday and
Thursday with mostly cloudy skies, and will warm up to near normal
Friday and Saturday.

&&

.AVIATION /12Z SUNDAY THROUGH 12Z MONDAY/...
Areas of fog with MVFR to IFR restrictions will continue through
about 13 to 14Z before rather quickly dissipating. Otherwise, VFR
returns for most of the forecast period as only some diurnal cumulus
and mid/high clouds with an approaching frontal boundary fill in
later this morning and afternoon. Some SHRA and isolated TSRA will
be possible both ahead of the front, with the highest chances for
TSRA being at coastal terminals this afternoon in the vicinity of
the nearly pinned sea breeze. This sea breeze is expected to make it
as far inland as JAX by this evening with a wind shift from
southwest to southeast. The aforementioned front moves through late
in the forecast period, with winds quickly veering towards the north
overnight and some lower clouds in the 035 to 050 range lingering as
well.

&&

.MARINE...


Ahead of an approaching cool front, onshore winds will veer
southerly across the waters Today. The slowing front will gradually
move north to south through the waters Sunday night bringing showers
and isolated thunderstorms as the front stalls through Monday. In
the wake of the front, high pressure will build to the north
resulting in strengthening northeasterly winds Monday and the onset
of a multi-day period of strong onshore winds throughout the
upcoming week, likely requiring an extension to the current Small
Craft Advisory. Much stronger high pressure will wedge along the
coast Wednesday resulting in further strengthening and potential for
gales and seas building potentially up to 15 feet across the waters.
As high pressure breaks away from the eastern seaboard late in the
week, onshore winds will begin to relax.

Rip Currents:

Increasing southerly winds will lead to a High risk of rip currents
today at area beaches as surf builds toward 3-5 feet. Fast-moving
longshore currents are also expected. Throughout the week ahead,
surf zone will become hazardous with a High Risk of strong rip
currents each day from Monday through Friday and high, rough surf
developing by Tuesday. Given the battering surf, minor beach erosion
is possible after days of rough surf.

&&

.FIRE WEATHER...
- High Afternoon Dispersions Inland Se Ga Sunday
- Critically Low Min Rh Over Interior Ga Tuesday

A frontal boundary will approach the area Sunday and move through
Sunday Night, which will bring more of a southwest flow except near
the coast and the return of shower & t`storm chances, especially
over inland GA and near the I-95 corridor to the coast where the
best convergence is expected. Areas of high dispersions will be
likely across inland southeast GA ahead of the front where the
strongest low/mid level winds are expected. Much stronger high
pressure builds in from the north for Monday and remains persistent
through mid week, returning breezy onshore winds and mostly cloudy
conditions with chances for showers the closer to the coast.
Critically low minRH values are forecast Tuesday for portions of
inland southeast Georgia, and will improve Wednesday.

FOG POTENTIAL AND OTHER REMARKS: Patchy fog potential Sunday morning
for north central Florida.
