Synopsis
High pressure will prevail through Saturday with a mainly dry
cold front passing through Saturday night into Sunday morning.

High pressure will then return through much of next week,
although at least one low pressure system could affect the area
mid to late next week.

Near term until 6 am Saturday morning
Tonight: no significant changes were made to previous forecast. A
mid upper lvl low will push further off the northeast coast,
helping maintain a northwesterly flow aloft over the southeast
united states. At the sfc, high pressure centered over the mid-
atlantic states will shift offshore tonight, allowing light
northeast winds to become more southerly overnight. Given the
setup, dry conditions will persist through the night while winds
decouple under favorable radiational cooling conditions.

However, the light onshore wind along with a few strato-cu clouds
could drift onshore late, especially south of the savannah
river, will help keep temps warmer tonight than the previous
night. In general, lows should dip into the lower middle 40s
inland and upper 40s lower 50s near the coast. Shallow, patchy
ground fog is possible, mainly over the south ga zones, but
confidence not high enough to put in forecast.

Short term 6 am Saturday morning through Monday
Pretty good model agreement this period leads to high forecast
confidence. High pressure will be giving way to an approaching cold
front Saturday but increasing southerly winds will bring warmer
temperatures. The front is expected to move through Saturday night
into Sunday morning but limited moisture will only bring small rain
chances to the area. Cooler temperatures will move in behind the
front Sunday into Monday and could be cold enough mid 30s Monday
morning for some frost across inland areas. Can't even completely
rule out freezing temperatures in the normally colder inland rural
spots, mainly toward the csra midlands where winds should be less.

Lake winds... Winds will increase on lake moultrie Saturday night
into Sunday as a cold front passes through the area, possibly
reaching marginal advisory levels.

Long term Monday night through Friday
Dry high pressure is expected to prevail much of next week but
a gulf surface low could lift northeast late in the week and
potentially bring some precipitation.

Aviation 00z Saturday through Wednesday
Tonight:VFR conditions still expected to prevail through 00z
Sunday. Some strato-cu could move into ksav after 08z tonight,
but think it will stayVFR. Patchy shallow ground fog possible
late, especially ksav,but probabilities not high enough to
mention in taf.

Extended aviation outlook: brief minor restrictions possible
Saturday night into Sunday morning due to low clouds showers
with a passing cold front. Breezy gusty conditions over 20 knots
at times Saturday afternoon through Sunday afternoon.

Marine
Rest of tonight: no significant changes made. A northeast
oriented pressure gradient within a high pressure regime will
produce northeast winds around 15 kt and seas as high as 3-5 ft
this evening, but expect condition to improve later in the
evening as the main center of high pressure to our north
reaches the mid-atlantic coast. Overnight, the pressure
gradient will begin to relax as the center of high pressure to
our north shifts off the mid-atlantic coast. The pattern change
will eventually turn winds from northeast to southeast
overnight. In general, winds will diminish to 5-10 kt after
midnight while seas range between 2-4 ft.

Saturday through Wednesday: conditions will go downhill Saturday as
the pressure gradient tightens ahead of an approaching cold front
but should stay below advisory levels until Saturday night when the
front passes. Best chances appear to be across the sc waters outside
charleston harbor and across the ga offshore waters. Conditions will
then improve later Sunday with some deterioration again toward mid
week when another cold front is expected to move through Tuesday
night, although no advisories are anticipated at this time.

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.
