646 AM EDT Sun Sep 7 2025
.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 637 AM EDT Sunday: No major changes to the forecast this
morning.  Temperatures are on track to bottom out in the mid-60s
in the next hour or so.  Dewpoints continue to fall slowly as dry
air filters in behind the cold front.  Scattered patchy fog and
low stratus have developed across the low terrain, more or less as
expected.  Other than a few sprinkles over the northern Foothills
and Piedmont, it`s dry across the area, and fog should clear
quickly after the sun come sup.  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.  Today 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
retograde 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 /12Z SUNDAY THROUGH THURSDAY/...
At KCLT and elsewhere: Patchy dense fog and low stratus are in
place across the terminal forecast area, but should not persist
long once the sun is up.  Expect quick improvement in visibility
after sunrise, and somewhat slower 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 day, turning NE tonight.  Clearing over
the NC terminals appears likely tonight, while at least SCT cloud
coverage - but without much chance of flight restrictions - will
remain in place across SC.
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.
