Synopsis
A stationary front will linger off the coast today. High
pressure will past north of the region Wednesday, then shift
into the atlantic Thursday. A surface trough will develop inland
on Friday and prevail into the weekend.

Near term until 6 pm this evening
Only subtle changes for the latest update, mainly to slow the
diurnal climb in temps due to insolation being limited by
various layers of clouds.

The stationary front looks to have cleared the entire forecast
area, both land and the coastal waters. Extensive jet stream
cirrus cirrostratus clouds encompass the entire region, and with
daytime heating, diurnal cumulus will develop in advance of the
sea breeze. The change to a continental air mass will lead to
slightly less humidity and temps a tad below normal for late
june, as highs reach 85-90f inland from the immediate coast.

We're within a fairly nebulous pressure pattern between the
offshore stationary front and canadian high pressure moving
into the ohio valley. There's also a fast moving mid level short
wave that reaches near our NW tier by nightfall. That feature
plus the sea breeze and differential heating boundaries will be
the main drivers for convection this afternoon. We continue to
show isolated to scattered coverage due to pwat's no more than
80-90% of normal. The greatest probabilities of showers and
t-storms will be in the 30-40% range near the altamaha river,
where there is better moisture profiles.

The overall thermodynamic atmosphere is very unimpressive, but
with the associated dry air and 0-6 km in excess of 30 kt,
where boundary collisions occur we could experience some
isolated strong wind gusts.

Short term 6 pm this evening through Friday
Tonight: any residual convection will quickly dissipate after
sunset. Dry conditions will prevail through the night. Lows will
range from the mid 60s across interior southeast south carolina
to the mid 70s at the beaches.

Wednesday through Friday: we'll get a short break from the typical
summertime heat and humidity Wednesday before it slowly return
Thursday. Shower and t- storm chances are below average
Wednesday, then creeping up Thursday and Friday.

The broad trough in the east lifts out and gives way to building
heights aloft from a building sub-tropical ridge centered near the
nw bahamas Wednesday that becomes positioned about midway between
florida and bermuda Thursday into Friday. Moisture is definitely
lacking Wednesday, with pwat's struggling to get above 1" across our
northern zones, or roughly 2 standard deviations below normal. This
is due to dry high pressure to our north holding the moisture to our
south. The high is forecasted to move offshore into the atlantic
Thursday, allowing SE flow to pump in higher pwats across our area,
much closer to normal for this time of year. The sea breeze is the
main driver of any diurnal convection during this time, and this
supports at most isolated coverage across interior SE ga Wednesday.

With better moisture Thursday we are forecasting 30-40% pops, mainly
for SE ga. Pops taper northwards into SE sc where enough dry and
subsidence aloft may remain in place to only allow afternoon cu
development. But by Friday the moisture will be in place across our
entire area. With temperatures topping out near 90 degrees and
plenty of instability in place, pops range from 40-50%. Isolated
severe storms with damaging winds are possible.

Long term Friday night through Monday
Nearly zonal flow will persist aloft with surface high pressure in
the atlantic. Southerly flow around the high will advect plenty of
moisture into the southeast as an inland trough develops this
weekend. The result will be the typical summertime
shower thunderstorm pattern with the coverage and intensity trending
upwards each day into the weekend.

Aviation 18z Tuesday through Sunday
Vfr. A few showers tstms will meander around ksav during the
afternoon, but impact probabilities are too low to show anything
more than vcsh and brokenVFR ceilings.

Extended aviation outlook:VFR Wednesday. Brief flight restrictions
are possible in afternoon evening shra tsra for ksav Thursday, then
both kcsh and ksav Friday and Saturday.

Marine
This afternoon: a stationary front will meander not far to the
se of the local waters, with the sub-tropical ridge deflected
to the e-se and continental high pressure in the ohio
valley midwest region. The end result will be a weak pressure
pattern driven mainly by sea breeze circulations. Easterly winds
will average no more than around 10 kt and seas will hold close
to 2 ft with isolated showers and t-storms, mainly south of
edisto.

Tonight: easterly winds will encompass the entire marine area
as continental high pressure remains well to the north and a
weak stationary front lingers to the south. Winds will remain
less than 10 kt with seas 1-2 ft.

Wednesday through Saturday: high pressure centered to our north
Wednesday will shift offshore Thursday and prevail in the atlantic
into the weekend. Easterly winds ~15 kt on Wednesday will veer to
the SE Thursday and ease a few kt as counter-clockwise flow develops
around the high, prevailing through the end of the week. Sea breeze
circulations will give a boost to the winds each day with
shower thunderstorm chances increasing into the weekend. Seas will
average no greater than 2-4 ft.
