.WHAT HAS CHANGED...
There are increasing indications that some shallow ground fog
could impact the region early Wednesday morning. Significant
fog development does not appear likely given 1000 hPa
condensation pressure deficits are progged to remain rather
high, but some very localized dense fog can not be completely
ruled out. A mention of "patchy fog" introduced to account for
about a 3-6 hour time period prior to daybreak.

&&

.KEY MESSAGES...
- 1) Rain-free conditions dominate this week as high pressure
  prevails.

&&

.DISCUSSION...
KEY MESSAGE 1: Rain-free conditions dominate this week as high
pressure prevails.

Quiet weather conditions will remain across the region as sfc high
pressure nudges across the area from the nearby Atlantic under
ridging building aloft. High temps remain on track to be near normal
this afternoon, peaking around the upper 70s north to lower 80s
along/south of the I-16 corridor. High temps are expected to warm
above normal mid to late week as a southwest wind occurs under broad
ridging aloft, reaching the mid-upper 80s away from coastal areas.
Unfortunately, no rainfall is forecast across the local area until a
front arrives late weekend and moisture return remains modest,
suggesting RH values dropping into the 20s west of I-95 each
afternoon through Friday. While RH values are critical, winds are
expected to top out in the 10-15 mph range (mostly near the coast
with a sea breeze), thus no fire weather headlines are in effect at
this time. However, its encouraged to exercise caution if burning
and heed any local burn bans as conditions remain very dry during
the week.

&&

.AVIATION /00Z WEDNESDAY THROUGH SUNDAY/...
22/00z TAF Discussion:
KCHS/KJZI/KSAV: VFR for much of the period. Some shallow ground
fog could produce some localized reduced vsbys at all terminals
early Wednesday morning. ASOS/AWOS observations at KSAV (when
observers are not on site) and KJZI could produce some highly
variable vsbys at times, but the shallow nature of any fog
layer should not impact operations.

Extended Aviation Outlook: VFR conditions will prevail through
Friday with a sea breeze likely to occur each afternoon. A few
showers and/or thunderstorms could impact the terminals late
Saturday.

&&

.MARINE...
High pressure centered across the Mid-Atlantic will slowly shift
south with a weakening cold front during the next few days, favoring
in a southerly flow across local waters for much of the week. Wind
speeds should generally remain around 10-15 kt or less with some
slight enhancement along the land/sea interface where a daily sea
breeze develops, then shifts inland. Seas between 2-4 ft this
afternoon (largest across outer Georgia waters) should range between
2-3 ft Wednesday through late week. A few showers and thunderstorms
could arrive this weekend.

&&

.CHS WATCHES/WARNINGS/ADVISORIES...
GA...None.
SC...None.
MARINE...None.
