Area Forecast Discussion
National Weather Service Charleston SC
432 PM EDT Sun May 11 2025

.SYNOPSIS...
A front will remain stalled near the area, before lifting north
of the region by midweek. High pressure is expected to return
late week.

&&

.NEAR TERM /UNTIL 6 AM MONDAY MORNING/...
Deep moisture remains across our area as a warm front slowly
lifts north. The radar is very active with showers and
thunderstorms occurring across a large portion of our area.
Heavy rainfall will cause flooding concerns to persist,
especially in areas of training. SPC Mesoscale Analysis points
to MLCAPEs of 500-1,000 J/kg and SRH around 100 m2/s2 around the
front. This is where the strong to severe thunderstorms are
most likely, along with the risk for a brief tornado. Otherwise,
categorical POPs will persist tonight, with up to remain
through the night as the sfc low over the Deep South begins to
track east. Some areas may receive an additional 1-2" with
locally higher amounts. Low temperatures are forecasted to range
in the mid to upper 60s.

&&

.SHORT TERM /6 AM MONDAY MORNING THROUGH WEDNESDAY/...
Active, wet weather will continue early this week. A closed mid
level low will remain over the Lower Mississippi River Valley
on Monday, making some slow northeast progress Monday night.
Shortwave energy will pass over the region ahead of this
feature, coincident with unseasonably high PWats, near or
possibly in excess of 1.8 inches (which is around climatological
maximums). At the surface, a stalled front will linger in the
vicinity before finally shifting northward as a broad low moves
into the region overnight. Ample large scale forcing and deep
moisture will bring another day of widespread showers and
thunderstorms. Additional rainfall amounts on average of 1-2
inches are forecast Monday through Monday night, with potential
for locally higher amounts as hinted by HREF probs of 10% for
greater than 3 inches over southeast Georgia. Given a few days
of soggy conditions, some flooding could be possible especially
in urban and poor-drainage areas and in areas where a large
amount of rain falls in a short period of time. In addition,
radar will bear watching for a couple strong to possibly severe
thunderstorms given some modest instability and shear present.
Locally strong wind gusts and perhaps an isolated tornado would
be the primary threats. Clouds and rain will keep temperatures
cooler than normal.

The mid level low will continue to slowly lift north-northeast
towards the Atlantic coast Tuesday into Wednesday, eventually
opening up into a trough. Less convective coverage is expected
overall than previous days, but there will still be at least
scattered showers and thunderstorms developing each day. Higher
activity/PoPs should become more focused over South Carolina on
Wednesday.

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/...
There will finally be a return to drier weather for late week
as high pressure returns both at the surface and aloft. Models
indicate a shortwave could pass near or over the Carolinas on
Saturday and bring the potential for showers/thunderstorms, but
otherwise the forecast is largely dry during this period.
Perhaps more notably will be the warming temperatures. Highs are
expected to reach the low to mid 90s Friday and Saturday, with
even higher heat indices possibly in the 100-105F range in
spots.

&&

.AVIATION /20Z SUNDAY THROUGH FRIDAY/...
18Z TAFs: Periods of showers and thunderstorms are likely
through the rest of the TAF time period, resulting in
reductions in ceilings and visibilities. Winds will increase
towards the end of the TAF time period.

Extended Aviation Outlook: MVFR or lower cigs and/or vsbys
possible through Tuesday as a front remains stalled nearby and
several rounds of showers/tstms move through.

&&

.MARINE...
Tonight: A stationary front will meander across our area,
yielding SE winds between 10 to 15 kts. Though, there could be a
few gusts to 25 kt across our SC waters this evening. Seas will
average 3-5 ft. Additionally, periods of thunderstorms will
persist, with locally strong wind gusts and perhaps an isolated
waterspout.

Monday through Friday: A stalled front will linger over the
region early this week. Winds/seas will be highest Monday into
Monday night, and Small Craft Advisories have been hoisted for
the nearshore Charleston county waters and outer Georgia waters.
It is possible that the advisory could be expanded to the
remaining marine zones, but at this point conditions appear more
marginal. In addition, mariners should be alert for rounds of
showers and thunderstorms, which could produce locally strong
gusts and/or isolated waterspouts. Marine conditions will
improve Tuesday through late week as winds settle back to around
10 knots and seas 2-3 feet.

Rip Currents: Gusty winds, proximity to the full moon, and
swell of 2-3 feet every 8 seconds will maintain a Moderate Risk
of rip currents at all beaches on Monday. Current calculations
indicate a Low risk for Tuesday.

&&

.CHS WATCHES/WARNINGS/ADVISORIES...
GA...None.
SC...None.
MARINE...Small Craft Advisory from 5 PM Monday to 8 AM EDT Tuesday for
     AMZ350.
     Small Craft Advisory from 6 AM Monday to 8 AM EDT Tuesday for
