.DISCUSSION...
KEY MESSAGE 1: Gradual increase in rain chances early this week.

Rain chances will gradually increase this week as troughing
approaches from the west and deeper moisture spreads across the
Southeast via southerly flow. Mostly dry conditions will persist
Monday due to lingering influence of the ridge aloft, with only
a slight uptick in POPs. Rain chances then increase Tuesday as
the greatest influence from forcing and moisture overlap the
area ahead of a weakening cold front. However, guidance
continues to suggest the front will dissipate before reaching
the region, keeping precip coverage limited.

Through the remainder of the week, expect a typical summer-like
pattern with activity driven by weak forcing and diurnal heating.
This will support isolated to scattered showers and thunderstorms
each afternoon, triggering mainly along the sea breeze. The
threat for severe or hazardous weather is low at this time.

.AVIATION /18Z SUNDAY THROUGH FRIDAY/...
18Z TAF Discussion: The majority of cloud cover will consist of a
few cumulus this afternoon and cirrus streaming overhead through
the night. Winds will increase as a sea breeze pushes inland
later this afternoon into the evening. Otherwise, VFR conditions
will prevail at KCHS/KJZI/KSAV through 18Z Monday.

Extended Aviation Outlook: An isolated shower or thunderstorm could
result in brief flight restrictions Tuesday through the rest of the
week.

&&

.MARINE...
Today and Tonight: South/southwest winds will prevail along the
western periphery of an Atlantic high. Seas will range between 2-3
ft.

Monday through Friday: Conditions will remain below Small Craft
Advisory criteria through the period. High pressure will dominate
over the marine waters Monday, with a weak cold front possibly
approaching on Tuesday. High pressure will return through the
remainder of the period. Winds will generally be out of the south,
with a typical summertime pattern of a surge in gusts along the
coast with the afternoon sea breeze.
