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

A more unsettled pattern arrives tomorrow through the weekend,
yielding some very beneficial rainfall to the forecast area. A
surface low tracking across the Tennessee and Ohio River Valley
could bring periods of isolated to scattered showers and/or
thunderstorms tomorrow into Thursday. However, instability
remains very limited, thus thunderstorms that develop will
likely be weak and there is a low potential for significant
impacts.

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

&&

.AVIATION /18Z TUESDAY THROUGH SUNDAY/...
18Z TAFs: As some light showers pass through the region, a mention
of VCSH was added at KCHS/KJZI/KSAV. Thus, MVFR ceilings have been
noted as these showers pass through. This activity is definitely
weakening, however no notable impacts expected. Another round of
decaying showers and thunderstorms could move in from the west and
produce showers near the TAF sites in the last few hours of the 12Z
TAF period.

Extended Aviation Outlook: Flight restrictions likely this upcoming
weekend as another system approaches the region, yielding another
round of showers and thunderstorms at all terminals.

&&

.MARINE...
Through Tonight: High pressure will prevail over the marine waters
through the remainder of the afternoon, yielding northeasterly flow.
A weak boundary will push over the area late this afternoon and into
this evening, shifting winds to the southeast. Conditions will
remain below Small Craft Advisory criteria, however gusts could
approach 20 knots at times this afternoon.

Extended Marine: A front will push through the region Wednesday
afternoon, lingering in the vicinity of the marine waters into the
end of the week. Conditions Wednesday afternoon could approach Small
Craft Advisory criteria as southwesterly winds gust upwards of 25
knots. The current forecast keeps gusts just shy of advisory levels
and therefore no headlines have been issued at this time. Conditions
will remain well below SCA levels Thursday and Friday,
deteriorating this weekend as a stronger system impacts the forecast
area. Small Craft Advisories are likely this weekend across some of
the marine zones as low pressure develops off the SE coastline.

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 tomorrow (Wednesday).
