Synopsis
High pressure will build over the region this week and will
linger into early next week.

Near term until 6 am Wednesday morning
Tonight: a 5890 meter mid-level ridge will be over the region.

At the surface, a weak backdoor cold front seen on satellite and
via surface analysis sis till near or just north of the north
carolina south carolina border. The front will sag south, but
will not reach the area. Instead, high pressure to the north
will bridge across the front, leading to more cloud cover and a
shifting of winds to the east-southeast across berkeley and
northern charleston counties by daybreak.

Otherwise, conditions will be rainfree with unseasonably warm
weather to prevail. Temps on average are running 2-3f warmer
than this time last night, which suggests it'll be a little
warmer than last night. Lows will only be in the upper 60s and
lower 70s, with even some mid 70s along the immediate coast and
in downtown charleston. And as a result the record high min at
kcxm could be challenged (see climate section below).

Short term 6 am Wednesday morning through Friday
Short term guidance indicates the center of a h5 ridge will settle
over the southeast u.S. Wednesday through Friday. H85 temperatures
on Wednesday are forecast to range from 16 to 18c, warming to around
20c by Friday. On Wednesday, the temperature forecast will be
complicated by the position of a old front, likely dissipating over
the lowcountry Wednesday afternoon. In addition, a sfc ridge will
build south from high pressure centered off the mid-atlantic states.

Flow around the high should result in sfc winds to turn from the se,
likely supporting a sea breeze Wednesday afternoon. The passage of
the sea breeze and weak instability should support a few showers
along and west of the breeze. This scenario is supported by the
majority of the cams, I will highlight the region with schc pops for
showers. High temperatures are forecast to range from the mid to
upper 80s across the chs tri-county to the mid 90s across SE ga. On
Thursday, sfc high pressure is expected to shift over the western
atlantic as the mid-level strengthens over the cwa. The llvl onshore
flow and ridging aloft should maintain cinh through the day.

Thursday should be hot and dry, with temperatures 1-2 degrees
warmer than Wednesday. Llvl thicknesses should increase across
the region on Friday, maintaining cinh through the daylight
hours. Using a blend of mos, high temperatures are forecast to
range from the low to mid 90s along the coast to the upper 90s
across the inland counties. Afternoon dewpoints may mix into the
lower to mid 60s across the inland counties, with near 70 along
the coast. The combination of the temperatures and dewpoints
are expected to result in heat index values around 100 degrees
west of the coastal counties.

Long term Friday night through Tuesday
The hot and dry pattern will linger this weekend into next week. The
h5 ridge is forecast to remain centered over the southeast u.S.

Through this weekend, with the ridge shifting south over the gulf of
mexico early next week. However, a broad and strong h7 ridge will
remain centered over the deep south, with west and downslope h85
winds Sunday night into Tuesday. This pattern is forecast to
maintain h85 temps around 20c and 1000-850mb thicknesses above
1430m. Using a blend wpc and mos, high temperatures are forecast to
range from the mid to upper 90s across the coastal counties with low
100s across the inland counties. The high temperature records for
mon and tues may range very close to record highs, see climate
section below. Heat index values are forecast to reach heat advisory
criteria (105 degrees) across portions of SE ga sat-tues, within 1-2
degrees of criteria elsewhere across the inland counties. In fact,
the climate prediction center has highlighted the forecast area with
a high risk of excessive heat for 5 28 - 5 30. The heat wave
potential will be highlighted in the hwo.

Aviation 02z Wednesday through Sunday
Vfr will dominate. However, with the interaction of the sea
breeze and a nearby cold front on Wednesday there might be a
shra or possibly a tsra at or near kchs. Odds of this happening
though are too remote to consider mention in the 00z TAF set.

Extended aviation outlook:VFR.

Marine
Tonight: a weak pressure gradient will bring generally south winds
15 kt or less. Seas will be about 2 ft. A backdoor cold front
will move into the waters north of the marine area late. But as
high pressure bridges across the front, winds will shift to the
e-se across the far northern waters after 5 or 6 am.

Wednesday through Sunday: high pressure will remain over the marine
zones through this weekend. Conditions are forecast to remain below
small craft advisory criteria. Seas through the period should range
from 1-3 feet, with 1-2 feet common Saturday. Winds are expected to
remain generally from the south around 10 kts.

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.
