Synopsis
Unseasonably warm conditions will prevail over the weekend as strong
high pressure holds offshore. A cold front will move through early
Tuesday with a stronger storm system to affect the area late next
week.

Near term /through tonight/
As of 555 am: observed temperatures have remain a few degrees
warmer than forecast early this morning. In addition, satellite
and observations indicate that cloud cover was expanding across
the cwa. I will update to warm temperatures and increase morning
cloud cover.

Previous discussion:
at the sfc, the forecast area will remain
between a bermuda high and a large low pressure system centered
over the southern great plains. At the mid levels, the western
side of a 590 dm ridge will persist over the region today and
tonight. This pattern should yield steady south winds through
the near term. The south low level flow has transported
saturated to nearly saturated air from the near shore waters
inland. The moisture will remain locked below a h925 inversion
this morning, producing periods of low stratus and patchy fog.

Forecast soundings indicate that the low clouds will mix higher
through the day. Using a blend of temperature guidance and to
some degree persistence, highs today should range very close to
values reached yesterday. Tonight, conditions will remain very
warm and dry. Low temperatures are forecast to range from the
upper 60s over rural areas, to the low 70s over the sea islands.

Fog and low clouds will likely redevelop over land this evening
and tonight.

Short term /Sunday through Tuesday/
Deep high pressure to the east should extend far enough westward to
keep rain chances at a minimum Sunday, although cannot completely
rule out a few showers/thunderstorms as the sea breeze moves inland.

By Monday an approaching cold front will bring a better risk for
showers and thunderstorms, as well as breezy conditions with gusts
around 30 mph or greater especially near charleston where the
pressure gradient should be maximized. Most showers should be
offshore by daybreak Tuesday with drier air moving into the area.

Temperatures look to remain well above normal for this time of year
Sunday with a bit of a cooldown Monday into Tuesday.

Long term /Tuesday night through Friday/
Generally drier/cooler weather through Wednesday before rain chances
return with the approach of a stronger storm system toward the end
of the week. Quite a bit of uncertainty remains regarding this
system so forecast confidence is lower than normal. Conditions look
at least marginally favorable though for some stronger storms
Thursday. Temperatures should be near or above normal through at
least Thursday night before likely dropping below normal
Friday/Saturday.

Aviation /10z Saturday through Wednesday/
Passing patches of high clouds will make forecasting the
placement and timing of low stratus challenging this morning.

Sfc observations and satellite data indicates that ifr stratus
and fog was common across the lowcountry at 130 am. Kchs should
see ifr ceilings redevelop by 7z, remaining through 14z. Ksav
appears less exposed to stratus with thin high clouds drifting
over the terminal. However, I will indicate a period of MVFR
ceilings with a tempo from 7z-11z. Gusty south winds are
forecast to develop over the terminals this afternoon. Tonight,
stratus sourced from the shelf waters should drift over kchs by
3z sun. I will indicate bkn015 by 3z.

Extended aviation outlook: restrictions due to low ceilings will be
possible at kchs/ksav Sunday morning and again Sunday night. Ceiling
and/or visibility restrictions are likely Monday into Monday night
due to more low clouds, showers and thunderstorms, then again
Wednesday night/Thursday. Breezy/gusty conditions also expected
Sunday afternoon and especially Monday afternoon.

Marine
Patchy sea fog will linger a few shelf water locations through most
of this morning. Otherwise, steady south winds will remain through
the near term, with gusts this afternoon. Wave heights are forecast
to favor 2-3 feet within 20 nm. Wave heights over amz374 should see
a slight increase in values heading into tonight, reaching 3 to 4
feet.

Sunday through Thursday: deteriorating conditions expected Sunday as
a cold front approaches with the best chance of an advisory in
charleston harbor where it will be breezy near the land/sea
interface. The worst conditions overall are likely Monday into
Monday night when winds could gust near 30 kt and seas build to 8 ft
near the gulf stream. Could see an advisory linger Tuesday morning
across the offshore ga waters but otherwise no significant issues
until Wednesday night/Thursday when another cold front approaches.

Tides/coastal flooding
Elevated tides are expected to continue over the weekend, aided
by persistent onshore winds. Minor saltwater inundation is
possible during the high tide Sunday night along the sc coast.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
