  locations and I-95 corridor

- Extended Dry Spell Continues through Early Next Week. Be very
  cautious with outdoor fires, check for local burn bans. Severe

&&

.NEAR TERM /THROUGH TONIGHT/...

Weak high pressure ridge will be over the region Tonight. Dewpoints
over the coastal waters will rise to levels that will be at or above
the water temperature. This setup will lead to fog development after
sunset along the coast, with this fog spreading inland through the
night. Beach front communities could have low visibilities
beginning as early as sunset. Dense fog advisories may become
necessary, especially for coastal counties.

Lows will trend above seasonal averages Tonight.

&&

.SHORT TERM /FRIDAY THROUGH SATURDAY NIGHT/...

High pressure over the area begins to shift away from the FL
peninsula on Friday as a frontal boundary begins to push towards the
southeastern CONUS. The frontal boundary pushes into the area
on Saturday.

Lingering fog along coastal locations will begin to lift and clear
by the mid morning hours on Friday. The persistent southwesterly
flow ahead of the front will continue to bring in moisture and
warmer temperatures across the area on Friday. There will be an
increase in cloud cover compared to the past couple of days.
Friday daytime highs will again reach into the low and mid 80s
across inland locations, while upper 70s along the coast as a
weak sea breeze develops during the afternoon hours. Overnight
lows in the mid to upper 50s across inland locations and the
lower 60s along the coast.

Another night of patchy to areas of fog will be in Friday night
as lingering moisture from the Gulf will allow for some fog to
develop along the I-75 corridor during the early predawn hours
on Saturday, with some locally dense fog. Southwest winds will
steadily shift to be northwesterly during the overnight hours
into Sunday. A similar spread of daytime temperatures compared
to Friday with highs in the lower to mid 80s. With the cold
front pushing through, overnight lows will be cooler across SE
GA locations with lows in the mid to upper 50s and lows in the
lower 60s across NE FL.

&&

.LONG TERM /SUNDAY THROUGH THURSDAY/...

Frontal boundary will clear the area on Sunday. Winds shift to
become northeasterly behind the front. Highs on Sunday will
mostly be in the upper 70s for most locations, with lower 80s
along the I-75 corridor. The northeast to easterly onshore flow
will shift to become southwest-southerly during the start of the
next week as high pressure centered over the Carolinas extends
south towards the southeast CONUS. Guidance is indicating the
next frontal boundary to arrive towards the local area by
midweek of the upcoming week as the high pressure moves off
towards the Atlantic sometime on Tuesday. This front could bring
some showers over SE GA and south towards locations along the
I-10 corridor in NE FL Wednesday morning. Otherwise, fog
development will continue to be of concern during the upcoming
week as moisture continues to be brought into the area due to
the southerly flow.

&&

.AVIATION /18Z THURSDAY THROUGH 18Z FRIDAY/...

Fog is expected to develop Tonight. The fog will first develop near
the coast around sunset, then move inland through the night. The fog
is expected to become dense, and may be slow to lift on Friday
morning. Once the fog lifts mid morning on Friday, prevailing VFR
conditions will be expected.

&&

.MARINE...

High pressure ridging over the Florida panhandle will weaken while
shifting slowly southeastward by Friday afternoon and Saturday. A
weakening and mostly dry frontal boundary will then push southward
through the Georgia waters on Saturday night, with this boundary
pushing across the northeast FL waters on Sunday morning. High
pressure will build east-southeastward from the Upper Midwest on
Sunday night towards the Mid-Atlantic states by early Tuesday, with
breezy onshore winds developing across our local waters from Sunday
afternoon through Monday afternoon. A stronger cold front may then
push eastward across the southeastern states next Wednesday and
Wednesday night, with southerly winds expected to develop ahead of
this front beginning on Tuesday.

Rip Currents: SE GA Moderate Friday
              NE FL Moderate Friday

&&

.FIRE WEATHER...

Persistent weather pattern of dry conditions, warm
temperatures, and rising afternoon humidity into the upcoming
weekend as the drought continues. Lingering low level moisture
from the Gulf will continue to bring the potential for morning
fog, with some locations with dense fog. Poor afternoon
dispersions will also be in play as minimal surface and
transport winds remain Friday and Saturday.

Breezy southwesterly winds will start to increase with gusts up to
15 mph across southeast GA on Friday afternoon as a weak cold front
slowly approaches from the northwest. Breezy southwesterly winds
will spread across the entire area Saturday as the aforementioned
front pushes into and through the region overnight Saturday into
Sunday. Northeasterly winds behind the front Sunday will trend
easterly by Monday. Another cold front will pass through the area
during the middle of next week which may offer breezy winds and low
relative humidity in its wake.
