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

Satellite water vapor showed a wide band of dry air extending from
the central Gulf north across AL. As a H5 trough ripples over the
Southeast U.S. today, dry air will gradually increase from the west.
Before the dry air arrives this afternoon, isolated showers may
drift over the coastal counties this morning, resulting in very
little rainfall. Increasing isolation this afternoon should allow
high temperatures to range in the upper 70s across the SC
Lowcountry, with highs around 80 possible across portions of SE GA.
A ridge of sfc high pressure will remain across the region tonight,
keeping ENE winds between 5 to 10 mph overnight. Low temperatures
are forecast to range from 55 to 60 inland to the low 60s along the
coast.

Extended: High pressure lingers into Tuesday before drifting
offshore by Wednesday. Will then see an upper level trough and its
attendant sfc cold front dig across the central CONUS as it slides
northeastward. This may result in renewed chances for isolated to
scattered showers during the latter half of the week - though model
guidance still varies on how the upper level pattern will evolve. As
such, the exact track and placement of the moisture axis could still
shift in the coming days, making it difficult to put too much
confidence behind one solution just yet. So, will continue to carry
NBM blend of 20-30% PoPs Thursday and Friday.

Outside of this, should see quiet conditions largely prevail, with
temperatures generally in the upper 70s to low 80s. A pinched
gradient will also remain in place through Wednesday, resulting in
gusts between 20 to 25 mph during the afternoon and evenings.
Otherwise, expect lows to remain mild, as temperatures only fall
into the 60s.

.AVIATION /06Z MONDAY THROUGH FRIDAY/...
6Z TAFs: The passage of a H5 trough will provide mid and high cloud
cover across the terminals through the TAF period. A sprinkle to
light shower is possible at KSAV after sunrise, but no restrictions
are expected. TAFs will feature northeast to east-northeast winds
through the period. Gusts near 20 kts are possible during the
daylight hours at KCHS and KSAV. KJZI should maintain occasional
wind gusts early this morning, with frequent gusts between 20-23 kts
today.

Extended Aviation Outlook: Breezy NE wind gusts around 20 to 25 mph
will continue through Tuesday. Rain chances increase late in the
week.

&&

.MARINE...
Today through Tonight: The sfc pattern should generally support
northeast 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 could approach Small Craft wind
conditions in the Harbor this afternoon, but is forecast to remain
just below criteria.

Tuesday Onward: Winds should gradually diminish Tuesday into
Wednesday as the gradient relaxes. However, seas will remain
elevated enough to keep the advisories going through Tuesday night.
By Wednesday night and Thursday, winds will diminish even more as a
cold front approaches from the west.
