Area Forecast Discussion
National Weather Service Charleston SC
408 PM EDT TUE JUN 28 2016

.SYNOPSIS...
A cold front will drop into the area tonight, becoming nearly
stationary and lingering nearby Wednesday and Thursday. The front
will lift back north on Friday as Atlantic high pressure builds
across the region. Another cold front will approach the area early
next week.

&&

.NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/...
Showers and thunderstorms will become more numerous through early
this evening across the area as a cold front drops into the area
and interacts with an increasingly moist atmosphere. PWs now close
to 1.8" per latest SPC mesoanalysis, expected to continue rising
through late afternoon. We're also seeing increasing low-level
convergence along prolific convective outflow boundaries. An
expansion of upper jet divergence across southern SC will further
enhance mid-level ascent during this period. We maintained likely
pops for most areas through early to mid evening. DCAPE values are
elevated in southeast GA though by the time most of the convection
gets that far south the values will be lower. Still cannot rule
out an isolated damaging wind gust just about anywhere. Heavy
rainfall also expected given such high PWs and good convergence.
So far the activity has been moving to the ESE at a decent clip
which may minimize flooding concerns except in areas where
multiple storms move over the same area.

Precip coverage expected to decrease mid to late evening though
isolated to scattered showers/storms expected to continue
overnight as the surface front stalls over the area. Lows will be
in the low to mid 70s.

&&

.SHORT TERM /6 AM WEDNESDAY MORNING THROUGH FRIDAY/...
The mid to late week period looks fairly unsettled with a cold front
that stalls over or near the area early Wednesday into Thursday
before lifting back to our north on Friday. The large-scale pattern
will feature a broad mid-lvl trough of low pressure extending over
much of the eastern conus that gradually becomes less amplified
heading into the weekend. Overall coverage of showers and
thunderstorms is hard to pin down to any particular location at this
time, but in general we expect to see isolated to scattered
showers/thunderstorms each day as temperatures warm into the upper
80s to lower 90s. Given a lack of strong wind fields and pwats
around 2.0 inches, slow-moving showers and thunderstorms could be
heavy rainfall producers over the southeastern United States.

The most interesting day of the period appears to be on Thursday
when a more pronounced h5 shortwave rounds the base of the mid-lvl
over the southeast. The combination of this shortwave trough along
with the Piedmont trough inland and lingering sfc front near the
area should result in a larger coverage of showers/thunderstorms,
some of which could produce heavy rainfall and an isolated occurrence
of a damaging wind gust. At this time, the Tri-County area should
see the greatest potential for a stronger thunderstorm given a setup
of moderate instability below the best upper-lvl divergence
associated with a departing h25 jet. By Friday, the flow aloft
becomes slightly more zonal and the sfc front will have dissipated
or lifted well to our north ahead of high pressure beginning to
shift over the area late. Although most substantial forcing will no
longer be present over the area, isolated to scattered showers and
thunderstorms will be possible, especially during afternoon hours.

&&

.LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/...
The weekend will feature more typical summer weather, with the
Bermuda-Azores High and Piedmont trough to encompass the synoptic
pattern. Zonal flow aloft and mid level heights up near 5920-5940
meters will limit the amount of convection both Saturday and Sunday
to generally 30 or 40 percent. Low level thickness and 850 mb
temps are a little above normal, so max temps will peak around 93-
95F. With dew points in the lower and middle 70s will generate heat
indices as great as 103-105F each afternoon, but well below our July
1st Heat Advisory criteria of 110F or greater heat index.

An upstream cold front will attempt to approach early next week, but
the flow aloft stays fairly zonal, which indicates that the front
will struggle to get this far south. For that reason we won't go any
higher than 30-40 Pops for Independence Day and next Tuesday.

&&

.AVIATION /20Z TUESDAY THROUGH SUNDAY/...
Quite a bit of convection will impact both terminals through this
evening, especially KCHS as a cold front drops into the area. The
best chance for KSAV, other than isolated pre-frontal activity,
will be with a potential line of storms that move in during the
evening hours. It is not clear if the line will make it that far
south as it will be after sunset and the airmass will be
stabilizing. Carried vicinity showers through the night at both
sites given the lingering front and very moist environment.

Wednesday may again be active, especially during the afternoon.

Extended Aviation Outlook: Flight restrictions are possible
Wednesday and Thursday due to showers/thunderstorms that develop
near a lingering cold front. While there are less chances for direct
impacts Friday and Saturday, there is still some potential for
showers and thunderstorms around both CHS and SAV terminals.

&&

.MARINE...
A cold front will stall near the area tonight though most of the
marine area will remain south of the front. Thus we expect south
to southwest winds less than 15 kt through tonight, though
weakening slightly late tonight.

Wednesday through Thursday: A cold front will likely stall near or
just north of the coastal waters mid week, resulting in a fairly
weak pressure gradient over the area. Although occasional small
surges will be possible due to the seabreeze circulation and
nocturnal jetting, winds will generally be no higher than 10-15 kt.
Seas will range between 2-3 ft through the period.

Given a rather slackened wind field Wednesday and Thursday morning
along with the proximity of a cold front and the expectation of
convergent cloud lines, there might be an enhanced risk for
waterspouts. There is also the potential for greater coverage of
showers and t-storms than what is typical.

Friday through Sunday: The Atlantic ridge will become the dominant
weather feature while a Piedmont trough prevails inland. In general,
southwest synoptic flow will prevail at or below 15 kt, with seas
no higher than 3 ft.

&&

.TIDES/COASTAL FLOODING...
The upcoming Perigee occurs early on Friday, and the New Moon occurs
on Independence Day. This could allow for another bout of "King
Tides" and an increased risk of shallow coastal flooding late this
week into early next week.
