.SYNOPSIS... High pressure will extend across the region through
the week. Temperatures and humidities will gradually rise through
late week.


As of 145 AM Wednesday...

1025+ mb surface high pressure will continue to extend from off the
mid-Atlantic coast southwest across NC/SC today and tonight. The
high will gradually shift eastward with time. There continued to be
some mid level moisture trapped under the subsidence inversion in
place over inland areas of NC (see previous discussion). This
inversion will persist into the afternoon with scattered mid level
clouds likely continuing. Partly to mostly sunny skies today will
yield highs around those observed Tuesday. Expect 86-91. As the
ridge axis gradually shifts east tonight, a continued slow rise in
dew points and humidities will occur. This will yield lows mostly in
the mid to upper 60s tonight.


As of 145 AM Wednesday...

The surface ridge axis will push offshore leading to a WSW flow
aiding warming as the mid level ridging strengthens over the
southern Appalachians. Continued mainly sunny, dry, and becoming hot
Thursday. Highs in the upper 80s to mid 90s N to S. Lows in the
upper 60s to lower 70s.


As of 245 AM Wednesday...

Chances of rain remain miniscule in the extended period. A weak and
moisture-starved surface front edges southeast and into NC on Friday
and progresses south of the area by later Saturday. Concurrently, a
strong upper ridge builds north and parks directly overhead through
the weekend. High temps on Friday will max out in the low to mid
90s, and very modest post-frontal cool air advection in easterly
flow over the weekend will be offset by the building ridge aloft to
allow highs to reach 90 to 95 Sat and Sun. The upper ridge slowly
deamplifies, but maintains its dominance through midweek, with dry
and slightly above normal temperatures - within a couple
degrees north or south of 90 - lingering through mid week.


As of 650 AM Wednesday...

24 Hour TAF Period: There is a high confidence of VFR conditions
continuing through the 24 hour TAF period with high pressure in
control. Patchy ground fog should develop late tonight and early
Thursday around KRWI, where MVFR VSBYS will be likely between 09z-

Outlook...VFR conditions and light winds will generally prevail
through mid to late week with strong subtropical ridging over the
