.DISCUSSION...
KEY MESSAGE 1: Rain chances will increase Wednesday through the
weekend, though no significant impacts are expected at this
time.

The latter half of the week marks the onset of a gradual
transition toward a more unsettled pattern, although coverage
could remain limited. A surface low tracking across the
Tennessee and Ohio Valleys could bring periods of isolated to
scattered showers and/or thunderstorms Wednesday into Thursday.
Instability looks meager, so any thunderstorms that develop are
expected to be weak and non-severe, with low potential for
significant impacts.

A second system could affect the region Friday into the
weekend, bringing another round of showers/thunderstorms.
Similarly, the risk of hazardous weather remains low at this
time.

.AVIATION /08Z TUESDAY THROUGH SATURDAY/...
The 06z TAF period begins with mostly VFR conditions across the
area, though there are still remnants of the MVFR stratus from
Monday. Overall, VFR conditions are expected to prevail at KCHS,
KJZI, and KSAV through 06z Wednesday. Over the next few hours,
we could still see MVFR ceilings move back in, mainly at KJZI
and KSAV. This stratus should finally dissipate for good by
sunrise. Otherwise, a diminishing area of showers and
thunderstorms will move towards the area from the northwest on
Tuesday but all model guidance shows it dissipating and not
impact the terminals.

Extended Aviation Outlook: Possible flight restrictions within
isolated/scattered showers and thunderstorms that could impact
the terminals during the latter half of this week.

&&

.MARINE...
Through tonight: Northeast flow will continue this morning
before the gradient falls apart and results in very weak flow
into the afternoon. The sea breeze will produce some modest
onshore flow, but speeds should mostly top out around 10 knots
(perhaps 10-15 right along the land/sea interface). Overnight,
southerly flow will increase and could reach 10-15 knots by
sunrise Wednesday. Seas will steadily diminish through the
period, highest this morning with 2-4 ft on average and up to 5
ft in the outer waters, becoming 2-3 ft late tonight.

Conditions are expected to decline Wednesday as a cold front
approaches, with winds and seas nearing Small Craft Advisory
levels. Southeast winds will gust 20-25 knots, with seas
building to 3-5 ft. The latest forecast remains below SCA
criteria; therefore, no headlines are anticipated. A more robust
system later this week or this weekend could bring another
period of elevated winds and seas, potentially leading to Small
Craft Advisory or low-end gale conditions.

Rip Currents: Higher-period swell and gusty S/SW winds will
result in a moderate risk of rip currents for all southeast
South Carolina and southeast Georgia beaches Wednesday.
