.SYNOPSIS...
Dry high pressure lingers over the area through the weekend with
temperatures steadily warming each day. A cold front will approach
from the west on Monday and could bring some showers and a few
thunderstorms to the area on Monday and Tuesday.

&&

.NEAR TERM /THROUGH TODAY/...
As of 135 AM EDT Friday: Any lingering cloud cover has shifted east
of the CFWA as mostly clear skies prevail. No major changes to the
forecast as it remains on track. Only made minor tweaks to current
observations and latest model trends.

Despite largely calm winds, lows tonight will end up a few
degrees above normal, with all areas expected to remain well above
freezing. Did make minor adjustments to temp and dewpoint per recent
obs trends, with most sites having slightly higher dewpoints than
expected at this hour. Dewpoint depressions still look too large
to expect fog thru daybreak. Increasing S/SSW flow will allow for
much warmer highs on Friday (~8-10 degrees above normal). Temps will
climb into the upper 70s to lower 80s across the mountain valleys
and east of the mountains Friday afternoon. Elevations above 3500
ft will see highs range from the mid 60s to lower 70s. Breezy winds
will develop by Friday afternoon, remaining well below advisory
criteria, lingering through the end of the near term.

Forecast CAMs show the potential for a few showers to develop
again tomorrow afternoon. However, with the such a dry air mass
in place, precip is not expected to reach the ground. Regardless,
a few sprinkles cannot be entirely ruled out.

&&

.SHORT TERM /TONIGHT THROUGH SUNDAY/...
As of 124 PM EDT Thursday: An increasingly elongated upper ridge
will remain in place over the Southeast on Saturday, maintaining
southerly return flow at the low-levels.  So, a warming trend is
expected for Saturday and Sunday, with temperatures some 10-12
degrees above normal over much of the area.  Breezy WAA winds are
expected each afternoon, but the influx of moisture should keep
humidity high enough to preclude any fire weather issues.

&&

.LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/...
As of 159 PM EDT Thursday: Guidance depicts a compact upper
low lifting out of the southern Great Plains on Monday, then
riding up and over the deteriorating ridge across the Southeast.
This will further hasten the ridge`s demise, leaving us under a
wave, unsettled pattern for the remainder of the period.  A surface
cold front is progged to cross the area Monday night into Tuesday,
though as the supporting upper trough pivots north, it may lose
some steam as it arrives.  The favored solution among the latest
cycle of global ensembles depicts the front stalling somewhere
over South Carolina, either over our Upstate zones or somewhere
just south.  At least token thunder chances are expected for much
of the forecast area given the front`s timing.  Temps will remain
above normal through the period.

&&

.AVIATION /06Z FRIDAY THROUGH TUESDAY/...
At KCLT and elsewhere: VFR conditions will prevail through much of
the forecast period. Any leftover mid-level clouds have shifted
east of the terminals and skies have become mostly clear. Can`t
rule out drifting thin cirrus overnight, but that`s about it. Winds
are light and variable at all TAF sites, but will quickly pick up
out of the south to south-southwest soon after daybreak. Low-end
gusts ~20 kts are expected during peak heating, but should quickly
subside by sunset. Some of the model guidance try to develop an
MVFR low stratus deck east of the mountains just before daybreak
Saturday and hinted at this in the KCLT TAF with SCT030 as this
falls at the end of the 30-hour forecast period. Otherwise, south
to south-southwesterly winds remain elevated overnight Friday
(5-10 kts), while passing spurts of upper- to mid-level clouds
can`t be ruled out throughout much of the period.

Outlook: Dry and VFR continues through the weekend. Rain and
associated restrictions return early next week and may linger
through much of the week.
