Synopsis
A cold front will move offshore tonight. High pressure will
build over the region on Friday and will linger through this
weekend. Low pressure may move across the region on Monday
night through Tuesday night.

Near term until 6 am Friday morning
This evening and tonight: the area will remain along the southern
base of a mid-lvl trough of low pressure shifting over the southeast
united states this evening, helping maintain a westerly flow
across the area. Mixing profiles continue to support wind gusts
generally up to 15-20 mph, but winds should gradually decrease
as diurnal heating is loss this evening. A dry cold front is
expected to continue shifting over the area this evening, then
offshore early tonight, helping maintain modest low-lvl mixing
and winds generally around 5 mph through the night. There
should be a brief period of mid clouds shifting over the area
this evening, but skies are expected to become clear overnight
as dry air continues to advect into the region behind the cold
front and mid-upper lvl trough aloft. In general, temps should
dip into the low mid 40s, coldest well inland.

Short term 6 am Friday morning through Sunday
A elongated area of high pressure sourced from central canada will
begin to build over the region on Friday. The center of the high is
forecast to settle over the forecast area Saturday and Saturday
night. The high will slide off the carolina coast on Sunday. The
weather through the period will be dry with clear to mostly clear
sky conditions. Daytime temperatures will peak around 70 with
morning lows in the 40s, warmest conditions on Sunday.

Long term Sunday night through Thursday
A broad low pressure system is forecast to track across the region
Monday night through Tuesday night. I will increase pops during the
period and will introduce schc for thunderstorms Tuesday afternoon
and evening. Cold air advection in the wake of the low may result in
upper 30s inland early Wednesday morning. Sfc high pressure is
expected to dominate the region Wednesday and Thursday.

Aviation 20z Thursday through Tuesday
Vfr conditions will prevail at both chs and sav terminals through
18z Friday. West-southwest winds could up to around 15-20 kt at
both terminals this afternoon.

Extended aviation:VFR through Sunday. Flight restrictions are
possible Tuesday and Tuesday night.VFR conditions return on
Wednesday.

Marine
This evening and tonight: west-southwest winds will peak near
15-20 kt at times this evening ahead of a dry cold front
approaching the waters by early evening. Winds should be highest
across northern south carolina waters. Seas will generally peak
near 3-4 ft in nearshore waters and up to 4-6 ft in offshore
georgia waters this evening. Jetting and surging is expected
behind the front with west-southwest winds turning more northwest
during the second half of the night. Cold air advection along
with 1000mb geostrophic flow near 30-35 kt will likely support
small craft advisory level conditions over offshore georgia
waters through the night and for roughly a 4-6 hour window
across northern south carolina waters beyond 10 nm from the
coast. Given the setup, a small craft advisory is now in effect
for northern south carolina waters starting at 11 pm tonight,
mainly for wind gusts near 25 kt and seas up to 6 ft closer to
20 nm offshore. A small craft advisory will remain in effect for
offshore georgia waters through the night. Weaker low-lvl
mixing near the coast and south, should keep winds just below
advisory criteria over remaining waters.

Extended marine: high pressure will build over the marine zones
Friday through Saturday, yielding winds generally below 15 kts. A
short window of gusty winds are possible Friday evening. Seas are
expected to range between 2 to 4 ft. Low pressure is forecast to
track near the region on Tuesday and Tuesday night. In the wake of
the low, gusty NE winds are expected across the marine zones. Small
craft advisory conditions may begin on Tuesday and remain through
Wednesday.

Rip currents: a moderate risk for rip currents will continue along
the beaches through Friday evening. Surf is forecast to feature
2 ft with 10 second periods. Northwest winds are expected during
the morning Friday, then will shift from the west.

Fire weather
A dry cold front will move across southeast georgia late afternoon
into early evening. Winds are expected to remain elevated with gusts
up to around 15-20 kt early evening. In addition, rh values will
remain near critical for the next couple hours away from the coast.

Fuels across southeast georgia are the lowest in our forecast area,
but values appear marginal. Per collaboration with SPC fire weather,
all of southeast georgia is in an elevated potential for fire danger
through late afternoon. A fire danger statement remains in place for
this region into early evening.

Friday: rh values as low as 25-30 percent and elevated offshore
winds could also cause fire concerns, especially if partners
report low fuel moisture.

Chs watches warnings advisories
Ga... None.

Sc... None.

Marine... Small craft advisory until noon edt Friday for amz374.

Small craft advisory from 11 pm this evening to 6 am edt
Friday for amz350.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
