Synopsis
A cold front will move offshore tonight. High pressure will
build over the region on Friday and will linger through this
weekend. Low pressure may move across the region on Monday night
through Tuesday night.

Near term until 6 am this morning
Early this morning: surface analysis shows that the secondary
cold front is poised to push through the forecast area over the
next few hours. Satellite imagery shows that this front will
bring few to scattered mid level clouds with it for southeast
south carolina, followed by clear skies. The forecast is very
quiet through sunrise.

Short term 6 am this morning through Sunday
An elongated area of high pressure sourced from central canada
will begin to build over the region on Friday. The center of the
high is forecast to settle over the forecast area Saturday and
Saturday night. The high will slide off the carolina coast on
Sunday. The weather through the period will be dry with clear to
mostly clear sky conditions. Daytime temperatures will peak
around 70 with morning lows in the 40s, warmest conditions on
Sunday.

Long term Sunday night through Thursday
A broad low pressure system is forecast to track across the
region Monday night through Tuesday night. I will increase pops
during the period and will introduce schc for thunderstorms
Tuesday afternoon and evening. Cold air advection in the wake of
the low may result in upper 30s inland early Wednesday morning.

Sfc high pressure is expected to dominate the region Wednesday
and Thursday.

Aviation 06z Friday through Tuesday
Vfr conditions will prevail at both kchs and ksav through 06z
Saturday. Westerly winds will become gusty late this morning and
this afternoon, with frequent gusts into the 20-25 knot range.

Extended aviation:VFR through Sunday. Flight restrictions are
possible Tuesday and Tuesday night.VFR conditions return on
Wednesday.

Marine
Tonight: a dry cold front will continue to push through the
southern and central waters this evening, then eventually
through the northern waters by midnight. Large isallobaric
pressure rises and decent mixing of 30 kt of geostrophic winds
supports expanding the small craft advisory headlines to now
include all atlantic zones. W-nw winds will reach 20-25 kt with
gusts to near 30 kt at times over the ocean, while seas climb as
high as 3-5 ft within 20 nm and up to 7 ft further out.

Charleston harbor will come close to advisory thresholds, but
for the present time conditions look to fall just shy.

Extended marine: high pressure will build over the marine zones
Friday through Saturday, yielding winds generally below 15 kts.

A short window of gusty winds are possible Friday evening. Seas
are expected to range between 2 to 4 ft. Low pressure is
forecast to track near the region on Tuesday and Tuesday night.

In the wake of the low, gusty NE winds are expected across the
marine zones. Small craft advisory conditions may begin on
Tuesday and remain through Wednesday.

Rip currents: a moderate risk for rip currents will continue
along the beaches through Friday evening. Surf is forecast to
feature 2 ft with 10 second periods. Northwest winds are
expected during the morning Friday, then will shift from the
west.

Fire weather
Friday: rh values as low as 25-30 percent and elevated offshore
winds could also cause fire concerns, especially if partners
report low fuel moisture.

Equipment
The kclx radar has failed. Technicians will look into the issue
this morning.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
