Area Forecast Discussion
National Weather Service Charleston SC
856 PM EDT Sun Apr 14 2024

.SYNOPSIS...
High pressure will persist much of this week. A cold front
might impact the area late in the week.

&&

.NEAR TERM /UNTIL 6 AM MONDAY MORNING/...
-- Changed Discussion --
No major changes were made for the late evening update. Cirrus
associated with a passing impulse aloft will spread over the
area through the night. The bulk of the thickest cirrus looks
to impact parts of Southeast Georgia. Expect partly cloudy to
mostly cloudy skies to prevail. Most of the cirrus should exit
offshore by daybreak. The boundary layer has decoupled in a few
spots this evening, but the surface pressure gradient is
forecast to tighten overnight as a lee-side trough to the north
sharpens a bit. This should keep a few knots of wind going.
Lows from the upper 50s well inland to lower- mid 60s at the
beaches and Downtown Charleston look on track. The boundary
layer may decouple enough in the Hinesville-Darien-Ludowici-
Glennville corridor to support an area of mid 50s. This assumes
the thickest cirrus exits off the coast several hours before the
diurnal minimum.

.SHORT TERM /6 AM MONDAY MORNING THROUGH WEDNESDAY/...
Deep layered ridging expected during the period, though the
upper ridge will slightly weaken on Wednesday. Dry weather and
well above-normal temperatures expected. Sunny skies on Monday
will give way to extensive high clouds Tuesday into Wednesday.
Highs Monday and Tuesday will push into the upper 80s away from
the coast, while Wednesday is mainly in the middle 80s.

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/...
A zonal flow will remain in place through Saturday, with mainly
dry weather and above normal temps. A weak dry cold front may
drop into the area on Friday. Highs on Friday could be the
highest of any day this week due to compressional heating ahead
of the front. A few spots could touch 90 degrees. Otherwise,
highs will be in the upper 80s through Saturday, then slightly
cooler on Sunday.

.AVIATION /01Z MONDAY THROUGH FRIDAY/...
15/00z TAF Discussion:
KCHS/KJZI/KSAV: VFR through 16/00z Tuesday.

Extended Aviation Outlook: VFR.

.MARINE...
-- Changed Discussion --
Tonight: Atlantic high pressure will be in control as a broad
trough remains inland over parts of the east and southeast
states. There`s a enough of a gradient between these two
features, plus 15-20 kt of wind at 925 mb to result in mostly
S-SW winds of 10-15 kt and a little gusty over all waters. Seas
of just 1-2 feet early on will build about a foot through the
night.

Monday through Friday: High pressure will persist over the
western and central Atlantic Monday through Thursday,
maintaining persistent S to SW flow over the local waters. Winds
will generally be less than 15 kt, though we could see a slight
enhancement in the late afternoons along the coast due to the
sea breeze. Wind directions become a bit chaotic on Friday as a
weak cold front drops into the area, then likely dissipates.
