.SYNOPSIS...
High pressure will dominate the weather pattern through the
next seven days with dry conditions and near to above normal
daytime temperatures.
&&
.NEAR TERM /THROUGH TONIGHT/...
-Dry airmass remains with slightly cooler temperatures.
Strong ridging east of the Appalachians will continue to control our
weather through tonight. Dry forecast on tap due to limited
deep moisture. Winds remaining mostly out of the north. Although
pwat readings remain below an inch, with the higher values
residing along the coastal plain through the period. This shows
up in the dewpoint fields, with dewpoint values in the low to
mid 60s east, and the mid to upper 50s west. The higher moisture
should lead to a little more cloud cover across the east this
afternoon and into tonight. Even though the NBM does show partly
cloudy skies tonight, can not rule out another round of stratus
moving in from the north again very late tonight. Temperatures
still forecast to remain below normal again tonight, with lows
in the upper 50s to lower 60s. The airmass should remain too dry
for any fog formation.
&&
.SHORT TERM /THURSDAY THROUGH FRIDAY NIGHT/...
Key message(s):
- Surface ridging and calm weather expected through the end of
  the week.
Weak positively titled upper troughing continues to shift
offshore, as a very strong surface high slides across eastern
Canada. As a result, surface ridging will remain in place as
northeasterly low level continues down lee of the Appalachians;
northeasterly winds will weaken somewhat on Thursday before
strengthening again Friday. While some airmass moderation will
start to bump dew points and PWAT`s up, precip chances remain
near zero through Friday but temps will rise to near average (in
the mid- upper 80`s).
&&
.LONG TERM /SATURDAY THROUGH WEDNESDAY/...
Key message(s):
- Warm and dry conditions expected into next week.
The overall synoptic pattern really will not change much over
the next, at least in regards to its sensible weather impacts as
a long wave quasi-omega block remains over the northern tier of
the US. Surface ridging will continue to extend down lee of the
Appalachians as the Canadian high sags southeastward over the
weekend. With a relative lack of advection as the entire airmass
in the Mid- Atlantic and Southeast steadily moderates and
heights rise, temps will climb back above average over the
weekend despite northeasterly flow. Moisture however will be
limited in its return and precip chance remain near zero through
the middle of next week.
&&
.AVIATION /18Z WEDNESDAY THROUGH MONDAY/...
Brief periods of MVFR ceilings possible through the afternoon in the
eastern Midlands.  Otherwise VFR conditions will prevail for the
remainder of the forecast period.
Strong high pressure will continue to build into the region from
the north. This will result in a northerly flow through the period.
Slightly deeper moisture across the eastern Midlands will keep KOGB
bouncing between scattered to broken mvfr cloud bases through the
early afternoon before rising to vfr.  Better mixing and slightly
drier air across cae/cub and the CSRA sites of ags/dnl this
afternoon will keep cloud bases within vfr.  Although all sites are
expected to remain mainly vfr into tonight, there remains at least
some chance at ogb for reformation of mvfr stratus towards sunrise
on Thursday.  Low confidence at this time, but will probably include
a scattered cloud group below 3kft towards sunrise at ogb to show
the potential. Winds remaining mainly out of the north through
the daytime hours both days, and light and variable overnight.
EXTENDED AVIATION OUTLOOK...A dry air mass will be over the
region this week and no significant aviation restrictions
expected.

.CAE WATCHES/WARNINGS/ADVISORIES...
SC...None.
GA...None.
