.NEAR TERM [Through Tonight]...

Another cool morning with temperatures in the mid 30s to around 40
across the interior and around 50 at the coast. A Frost Advisory
is in effect through this morning for interior southeast Georgia.

Surface high pressure over southern Georgia and South Carolina
this morning will settle east of the Carolinas by this evening. A
weak coastal trough along the coast of north central and northeast
Florida will move inland this morning, and a light easterly flow
will develop south of the ridge over the area today. Dry air will
remain in place across the area, and temperatures will rebound to
70-75F across the interior and the mid to upper 60s towards the
coast. Low level moisture will slowly tick upwards due to the
easterly onshore flow, and overnight lows will moderate into the
40s across the interior and remain 50-55F at the coast. Patchy fog
is possible across the interior towards daybreak on Wednesday.

.SHORT TERM [Wednesday Through Thursday]...

Dry conditions expected as upper level ridging stretching across
the eastern seaboard remains over the region. Moistening onshore
flow persists as surface high pressure builds from the Mid-
Atlantic states into the western Atlantic. Temperatures continue
to warm with near normal highs in the 70s on Wednesday increasing
to above normal highs in the mid 70s to low 80s on Thursday.

.LONG TERM [Friday Through Tuesday]...

Dry weather with a warming and moistening trend continues into
the weekend. Weakening surface high pressure over the western
Atlantic will shift more to the east resulting in a prolonged
period of onshore flow. Temperatures continue to be above normal
with highs in the mid 70s along the coast to the 80s inland
through the weekend. The next chance for rain will be for early
next week as a cutoff low ejects northward out of the desert
southwest and pushes a front towards the region late Sunday into
early next week.

&&

.AVIATION...
[Through 06Z Wednesday]

VFR conditions will prevail through the period. Light winds
overnight will become easterly near 10 knots by Tuesday afternoon.
Light winds are expected again Tuesday night.

&&

.MARINE...

Onshore flow will continue to weaken through mid week as near-
stationary high pressure centers itself slightly west of the area
waters across southeastern Georgia. Fair boating conditions and
lighter onshore winds are expected to continue through the week
and into the weekend as high pressure expands into the the western
Atlantic.
