.DISCUSSION...
KEY MESSAGE 1: Mild temperatures expected through midweek, then
a cold front should bring at least scattered showers on Thursday.

Rest of Today and Tonight: Water vapor imagery shows that dry air
has made its way into the western portions of the local forecast
area. This dry air is forecast to continue its eastward progression
and showers currently over the adjacent Atlantic waters will wane
into the afternoon. As clouds continue to clear with the arrival of
the drier air, temperatures will reach into the upper 70s/around 80
across most locations away from the coastline. Surface high pressure
will remain the dominate feature through the overnight period,
yielding NE winds 5 to 10 mph. Low temperatures are forecast to
range from 55 to 60 inland to the low 60s along the coast.

High pressure will be centered over the north Atlantic on Tuesday
which will allow for the northeast gradient along the coast to
gradually break down into Wednesday as a front begins to approach
from the west. The front should arrive into the area Friday morning
and then move offshore Friday night. For Tuesday and Wednesday,
shower activity should continue offshore over the coastal waters but
could try to push onshore at times. But overall, mostly dry. As the
front gets closer Thursday and into Friday, the potential is higher
for increased shower coverage though model guidance continues to be
rather underwhelming regarding the rainfall potential. The forecast
continues to feature 20-30 percent chances Thursday and Friday.
Temperatures will remain mild, with highs in the low 80s through the
week followed by mid to upper 70s over the weekend.

.AVIATION /18Z MONDAY THROUGH SATURDAY/...
Prevailing VFR through the 18Z TAF period at KCHS/KJZI/KSAV. A brief
moment of MVFR cigs at KSAV is possible over the next hour or two.
Gusty NE winds around 20 knots will wane with sunset, however winds
will remain elevated around 10 knots through the overnight
period.

Extended Aviation Outlook: Northeast winds could produce wind
gusts up to around 20 knots Tuesday afternoon and evening.
Increased shower coverage is expected with a front Thursday and
Friday.

&&

.MARINE...
Today through Tonight: The surface pattern should generally
support NE winds between 15 to 20 kts and gusts around 25 kts
through the near term. As a result, wave heights should remain
between 5 to 7 ft. Small Craft Advisories will remain in effect
outside the Charleston Harbor. Conditions in the Charleston
Harbor are just shy of Small Craft Advisory criteria, with wind
gusts in the 20 to 25 knot range.

Tuesday through Saturday: High pressure situated to the north will
drift further over the north Atlantic on Tuesday. This will keep the
tight pressure gradient and enhanced northeast flow across the local
waters going with speeds mostly in the 15-20 knot range. By
Wednesday, the gradient will relax and winds will turn more easterly
with speeds no more than 10-15 knots. Then for Thursday, a front
will approach from the west and winds will turn more southerly and
light (5-10 knots). The front is expected to pass through Friday and
Friday night with no significant surge behind it. Ongoing Small
Craft Advisories will come to an end across the nearshore waters on
Tuesday with decreasing winds and seas. The advisory for the outer
GA waters will extend into Wednesday to account for lingering 6 ft
seas.
