Synopsis
A weak cold front shift into the region tonight. High pressure
should then prevail into early next week with hot and mainly
dry weather expected. The best rain chances will likely be late
this week when troughing and moisture are most favorable.

Near term until 6 am Wednesday morning
Late this evening: the surface trough has nudged offshore and
behind it winds have turned northwesterly. They should then
remain light northwesterly through sunrise. Little moisture and
deep westerly flow along near the front will maintain dry
conditions across the region through the night. Winds are
expected to decouple fairly quick overnight despite a front in
the region. This should allow a fair amount of radiational
cooling, resulting in overnight lows in the lower 70s away from
the coast and mid upper 70s along the beaches.

Short term 6 am Wednesday morning through Friday
Moderate to high confidence this period. High pressure will
generally prevail at the low-levels while an upper trough closed
low persists across the deep south west of the forecast area.

Moisture will remain limited so no significant rainfall
chances amounts are expected. A weak coastal trough could impact
the area Friday but we still trended rain chances down from the
previous forecast based on the latest guidance which indicates
limited moisture (especially across sc). Could see a bit better
chance of morning fog Friday morning due to higher dewpoints.

Temperatures should stay near or slightly above normal until
possibly dropping a bit below normal Friday due to increased
onshore winds.

Long term Friday night through Tuesday
Surface troughing will prevail across the region with low
chances of mainly afternoon evening showers and thunderstorms.

Heat indices could peak near 105 degrees for some areas starting
Monday, especially south of i-16. Please note that we will
transition as scheduled to our regular heat advisory criteria of
110 degrees starting july 1.

Aviation 02z Wednesday through Sunday
Vfr conditions will prevail at both kchs and ksav through 00z
Thursday.

Extended aviation outlook: brief flight restrictions are
possible through the period from early morning fog stratus
(starting Friday) and mainly afternoon evening showers and
thunderstorms (especially Saturday).

Marine
This evening and tonight: a weak dry cold front will approach
from the west-northwest overnight, causing west-northwest winds
around 10-15 kt to turn more northerly and weaken through the
night. Seas will generally range between 1-2 ft, highest in
offshore georgia waters.

Wednesday through Sunday: the lack of strong weather features
through the period will preclude any significant marine
concerns.

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.
