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 south of the area
through early next week.

Near term until 6 am Thursday morning
Boundary collisions and moderately unstable conditions are
supporting scattered showers tstms across the interior early
this evening. Tstms will linger for a few more hours before
diminishing with the loss of insolation. Pops were adjusted
slightly for the next several hours to take current radar and
mesoscale trends into account. Expect mainly dry conditions
overnight with debris cloudiness gradually diminishing with
time. Similar to the past several nights, some marine-based
stratocumulus is expected to move inland from off the atlantic,
especially at the beaches. Lows will range from the mid 70s
inland to around 80 at the beaches and downtown charleston.

Short term 6 am Thursday morning through Saturday
The mid-level pattern will be in transition with troughing to our
north, high pressure to our southeast dissipating, and low pressure
even further to our southeast approaching as time progresses. At the
surface, our area will remain between high pressure in the atlantic
and a trough inland Thursday and Friday. By Saturday a cold front
will approach from the north, but models currently show it remaining
just north of our area during the daylight hours. Moisture will
gradually increase throughout the short term. Pwats will start ~2"
on Thursday, gradually increasing into Saturday. There are hints at
a band of 2.5" pwats approaching our area from the north, ahead of
the front on Saturday. The thunderstorm threat on Thursday is low,
with only a brief period of chance pops forecasted along the sea
breeze late in the afternoon. Friday the parameters improve
(moisture, lift, etc.), so we have pops a bit higher, into the
chance category for most of the area during the afternoon. On
Saturday pops increase from north to south, especially in the
afternoon. The highest pops are in the north near the approaching
front, where we have likely pops. These will need to be adjusted
with the upcoming forecasts. The risk of severe thunderstorms is
low. Though, heavy rainfall is possible due to the abundant
moisture. Temperatures will be near normal throughout the
period.

Long term Saturday night through Wednesday
Low confidence this period. The pattern doesn't change much until a
cold front likely pushes into the area this weekend, probably
starting Saturday night, before stalling over or near the area into
the middle of next week. Rain chances should end up being above
normal but confidence is lower regarding temperatures as much
depends on the location of the front and rain cloud coverage.

Probably the biggest issue this period will be periods of heavy rain
which could cause some flooding, especially near the coast early
next week when astronomical tides will already be higher than
normal.

Aviation 22z Wednesday through Monday
May need to include vcts or a brief tsra at kchs through 01z
depending on radar trends at issuance time, otherwiseVFR will
prevail at both kchs and ksav.

Extended aviation outlook: there is a low probability of flight
restrictions Thursday and Friday afternoon evening due to
showers thunderstorms. Flight restrictions appear more likely this
weekend into early next week due to a cold front.

Marine
Tonight: the expansive bermuda-azores high is again the most
prominent feature across the local waters. This will maintain
s to SW winds as high as 12-17 kt a good portion of the night,
before they start to veer more toward the SW and W and diminish
around 3-5 kt late with land breeze influences occurring. Seas
will average 2 to 3 feet throughout.

Extended marine: no small craft advisories are expected. The coastal
waters will be sandwiched between high pressure in the atlantic and
a trough inland through late week. A cold front will then move into
the area this weekend, then become stationary overhead or nearby
through early next week. The strongest winds Thursday and Friday
appear to be along the land sea interface each afternoon (including
charleston harbor) due to the sea breeze.

Chs watches warnings advisories
Ga... None.

Sc... None.

Marine... None.
