Area Forecast Discussion
National Weather Service Charleston SC
1017 AM EDT Mon Aug 6 2018

.SYNOPSIS...
Atlantic high pressure will continue over or near the area
through the middle of the week, as a lee side trough persists
inland. A cold front could approach the area from the northwest
late in the week.

&&

.NEAR TERM /THROUGH TONIGHT/...
Today: Aloft, a ridge of high pressure centered over the Southeast
United States will gradually slide west and weaken. At the sfc, high
pressure will extend from the western Atlantic while a lee trough
persists inland. The setup will favor a fairly typical summertime
pattern, with a slight chance to chance of showers/thunderstorms
developing across the region as convective temps are met early
afternoon. Most convection should develop along a seabreeze
circulation initially this afternoon. The main focus of precip
activity should then shift to upstream convection that gradually
drifts into inland zones late afternoon/early evening within a
light north/northwest flow. High temps should peak in the upper
80s near the coast to lower 90s inland.

Tonight: There isn't too much change to the overall synoptic pattern,
except that the mid and upper level anticyclone will retrograde
slightly west. This could allow for the tail of a short wave,
that crosses over the central and southern Appalachians by late
today, to skirt the area late tonight. While the bulk of the
models indicate that this feature won't have any impact on our
weather, some of the guidance suggests that this could support
some late night convection to brush the forecast area. For now
we are showing a decay of inland activity during the early and
mid evening, and keeping conditions rainfree overnight, aside
from maybe isolated late night showers approaching the coast due
to low level convergence. Temps will be very similar to what
they have been most nights this summer; lower and middle 70s
inland, upper 70s near the coast and in downtown Charleston.

&&

.SHORT TERM /TUESDAY THROUGH THURSDAY/...
The region will become situated between upper level troughing to the
north and ridging to the south. At the surface, Atlantic high
pressure will ridge across northern Florida, while persistent
westerly 850 mb flow prompts the development a lee surface trough
inland. The resulting southwesterly flow will allow a moist airmass
to remain in place, and PWats will be near 2 inches through the
period. The westerly/downsloping mid level flow will also keep temps
a few degrees above normal, and prompt capping that will limit the
coverage of afternoon convection to just isolated to scattered,
mainly triggering along features such as the pinned sea breeze and
outflow boundaries from inland (Piedmont) convection that are
powerful enough to break the cap. Storm motion will be slow toward
the east or southeast, and some localized flooding issues are
possible if storms persist over a location, especially given the
still saturated soils.

Convective focus will generally shift off the coast during the
overnight hours, with the exception of Tuesday night/Wednesday early
morning, when guidance is hinting at the passage of some shortwave
energy across the Pee Dee region, possibly bringing some scattered
overnight convection across the Santee River and Charleston Tri-
County area.

&&

.LONG TERM /THURSDAY NIGHT THROUGH SUNDAY/...
The area will be located between H5 ridging to the south and east
and a trough digging into the Mississippi Valley through the weekend.
At the surface, a cold front crossing the Mid-Atlantic looks to get
hung up north of the area late in the week, keeping us entrenched
within a sector of warm and moist west to southwesterly flow through
the period. Overall, near normal storm chances have been maintained
in the forecast, with the caveat that if the trough to our west
approaches close enough to induce height falls aloft locally, we
could enter a more active period over the weekend or early next
week. Temps will generally be seasonable.

&&

.AVIATION /14Z MONDAY THROUGH FRIDAY/...
VFR conditions will prevail at both CHS and SAV terminals through
Tuesday morning. However, temporary flight restrictions are possible
at either terminal this afternoon/early evening with showers
and/or thunderstorms. VCTS remains at both terminals between 18Z
and 2330Z today.

Extended Aviation Outlook: VFR conditions will prevail at both CHS
and SAV terminals through the week. However, brief flight
restrictions are possible with afternoon showers and/or
thunderstorms at either terminal each day.

&&

.MARINE...
Today and Tonight: High pressure will remain the dominant weather
feature over the coastal waters through tonight. Outside any
showers/thunderstorms winds will primarily be south/southwest and
remain at or below 10 kt. Expect winds to be highest along the coast
where a seabreeze circulation develops, then shifts inland. Seas will
peak around 2 ft, highest offshore.

Tuesday through Saturday: Atlantic high pressure will dominate
early in the week, bringing mainly light southwest winds. By
midweek, low pressure passing off the Northeast coast will result in
a tightened gradient locally as the Atlantic high slides over the
Sargasso sea and winds increase to moderate levels out of the west-
southwest. Seas will gradually build from 1-2 ft early week to 2-3
ft mid and late week.

Waterspouts: The convergence lines on the nearby Atlantic waters
do not have much vertical growth, at least so far. And with the
SPC Non-supercell Tornado Parameter mostly less than 1 unit, we
have refrained from issuing a Marine Weather Statement for
waterspouts. However, since the local Waterspout Index does show
a Moderate risk, we will continue to maintain a careful weather
watch.
