.SYNOPSIS...
Surface high pressure will build into the area today in the wake
of a front and linger through most of the week, resulting in fair
weather with below-normal temperatures and humidity.
&&
.NEAR TERM /THROUGH TONIGHT/...
As of 135 AM EDT Sunday: All quiet across the forecast area as a
potent cold front pushes to our east, ushering in a much drier air
mass behind it.  Dewpoints, already in the mid to even low 60s,
will fall throughout the night, likely hitting the upper 50s
across the higher elevations.  Lows are on track to bottom out
in the mid 60s by dawn, and in the upper 50s for the mountains.
ACARS and RAP data indicate a decent amount of low-level moisture
trapped beneath a developing postfrontal inversion, which supports
model trends toward patchy fog across the area - already beginning
to develop in some parts of the Piedmont/Foothills - and the
occurrence of some low cloud cover leading up to daybreak. A
few of the CAMs also depict a resurgence in shower activity
across the I-40 corridor before dawn...but confidence is low.
Whatever fog develops will scatter out quickly after sunrise, but
cloud cover will take longer to scatter out owing to what by then
will be a fairly robust inversion trapping any lingering moisture.
Nonetheless, as day wears on and increasingly dry air filters into
the western Carolinas, clearing will occur going into the afternoon.
Sunday should be a pleasant day, with highs in the 70s and
little chance of rain. Partly cloudy but generally dry
conditions will persist into Sunday night, and lows will drop
into the 50s.
&&
.SHORT TERM /MONDAY THROUGH TUESDAY NIGHT/...
As of 130 am EDT Sunday: A return of anomalously cool and dry/low
humidity conditions is expected during the short term. Although
the portion of a long wave trough over the Southeast is expected to
retrograde and weaken through the period, persistent confluent
flow associated with multiple rounds of height falls over the
northeast Conus and southeast Canada will support surface high
pressure and associated inverted ridging and thermal/moisture
trough down the Eastern Seaboard into our forecast area. Temps
will be almost 10 degrees below climo through the period, while
afternoon dewpoints will generally be in the upper 40s and lower
50s. Doesn`t get much better than that in the Carolinas in
early September.
&&
.LONG TERM /WEDNESDAY THROUGH SATURDAY/...
As of 145 am EDT Sunday: A broad/baggy trough will gradually return
to the Southeast during the extended, as a strong upper low/short
wave trough digs into southeast Canada and New England toward the
latter part of the week. Prior to this, inverted surface ridging
will be gradually weakening and the air mass modifying across our
CWA, with temps warming and humidity increasing. Having said that,
temps are forecast to remain below climo through the end of the work
week...but perhaps falling just shy of normal by Thursday. Temps
are then forecast to cool again by the end of this forecast cycle,
as inverted ridging re-strengthens across the East in the wake
of aforementioned short wave. Despite the steadily increasing
humidity, moisture and instability are expected to remain too
limited to support convection through the week.
&&
.AVIATION /06Z SUNDAY THROUGH THURSDAY/...
At KCLT and elsewhere: A soupy night on tap for the 06z TAFs with
convection fully ended, but lots of low-level moisture remaining.
Guidance is still keying on MVFR to IFR fog overnight across much
of the terminal forecast area, as well as potential for IFR or
worse ceilings in some locations.  Will leave TEMPOs for reduced
VIS/CIG at most sites.  Expect quick improvement in visibility
after sunrise, but only slow improvement in ceilings...since it`ll
take a while for the postfrontal inversion to fully mix out,
and thus moisture will remain trapped for much of the morning.
By mid-afternoon, all terminals should return to VFR conditions.
Expect NW winds through the period.
Outlook: Dry high pressure is expected into the middle of next week.
Fog and/or low stratus is possible each morning, especially in
the favored mountain valleys.
