Synopsis
Atlantic high pressure and an inland trough will prevail
through late week. A cold front will then push into the area
this weekend before stalling over or just to the south. Low
pressure may develop offshore along the front but should move
quickly to the northeast away from the area by mid week.

Near term through tonight
Deep layered ridging will continue to extend along and just
north of 30w into the coastal southeast states. The synoptic
pattern is relatively unchanged from yesterday and typical late
august weather is on tap with hot and humid conditions with
isolated to scattered diurnal convection developing across the
region once again. We suspect showers and tstms will develop in
the axis of the highest 850 mb theta-e air which should extend
along the i-95 corridor in sc down southward into inland SE ga
during the mid late afternoon hours. Sufficiently deep moisture
and typical late summer diurnal instability suggest slow moving
pulse tstms with locally heavy downpours. Similar to Wednesday,
a few stronger storms are possible but risk of severe weather
remains low. Temps will reach the mid 90s many areas this
afternoon with heat indices in the 104-106 degree range.

Tonight: any lingering evening convection will wane with the
loss of surface heating, resulting in thinning clouds overnight
with lows in the mid 70s most areas.

Short term Friday through Sunday
Moderate confidence this period. Surface troughing inland and high
pressure offshore will persist into Saturday before a cold front
sags south toward the area, likely pushing through southeast sc ga
Saturday night. Expect fairly typical summertime weather through
Saturday with mainly afternoon evening scattered showers and
thunderstorms before cooler and wetter conditions kick in for the
later half of the weekend as low pressure possibly develops offshore
along the front. At this point any low looks to remain well enough
offshore and weak and thus little to no impacts are expected across
our forecast area. Otherwise, the severe storm risk will remain low
(mainly just through Saturday) with a heavy rain threat mainly from
late Saturday through Sunday. Temperatures should stay above normal
through Saturday with heat indices peaking in the low to mid 100s
each afternoon for most areas away from the beaches before temps
likely fall below normal Sunday as rain cloud coverage increase.

Long term Sunday night through Thursday
Low confidence this period. There is a bit better agreement amongst
the latest gfs ECMWF that any weak low pressure system should remain
well offshore as it tracks to the northeast and away from the
forecast area Monday. However, the lingering front and upper level
energy will remain along with deep moisture so it looks to remain
more unsettled than normal through at least Wednesday. At this time
it appears as though heavy rain is the main concern with localized
flooding possible, especially near the coast around the times of
high tide.

Aviation 18z Thursday through Tuesday
18z tafs: mainlyVFR. Thunderstorms are possible near the
airports this afternoon. Brief flight restrictions are possible
if they directly impact the airports. Amendments may be needed
to add tempo groups once better radar trends develop.

Extended aviation outlook: periodic restrictions at kchs ksav
each day through Saturday, mainly from afternoon evening showers
and thunderstorms. More significant restrictions are likely
Saturday night through early next week due to increased
moisture rain coverage.

Marine
Through tonight: little change to our persistence forecast with
south to southwest flow below 15 kt and seas 1-3 ft.

Friday through Monday: atlantic high pressure and an inland
trough will result in mainly south southwest winds around 15
knots or less until a cold front likely moves through the waters
Saturday night. Weak low pressure is likely to develop at some
point offshore to the east of the local waters and shift to the
northeast late in the period. Overall the strongest winds will
likely occur near the sc coast, including charleston harbor,
where the best pressure gradient should set up. Seas will likely
stay 4 feet or less, although there is more uncertainty early
next week as much depends on the strength of the winds. At this
point we are not expecting small craft advisory conditions for
any of our waters.

Tides coastal flooding
Astronomical tides will be running close to minor coastal flood
advisory levels next week and onshore winds could lead to even
higher tides, mainly during the evening high tide cycles starting
Sunday. In addition, there is the potential for some heavy rain
around the times of high tide which could exacerbate any flooding
issues.
