Synopsis
High pressure builds across the region tonight, maintaining
dry weather into through early next week. A weak disturbance
approaches the region late Monday into Tuesday.

Near term until 6 am Sunday morning
As of 355 pm est Saturday...

latest surface analysis shows ~1025mb sfc high pressure over the
mid-south central gulf coast region. Quasi-zonal w-sw flow aloft
east of the rockies this afternoon. Some mid to high clouds
noted across the deep south, as a weak disturbance was noted
sliding across the southern plains toward the deep south.

Closer to home, a mainly clear sky over the region this
afternoon, as high pressure continues to build into the region
from the southwest. Did see some sct-bkn CU stratocu earlier
this afternoon with a narrow bay streamer, but that has scoured
out this afternoon with wind shifting diminishing over the past
few hours. Despite downslope flow aloft and plenty of sunshine,
modest cool air advection at the surface has kept temps a bit
cooler than normal today, largely in the low to mid 50s inland,
upper 40s to low 50s along the coast.

Mainly clear sky continues this evening, with temperatures once
again falling off quickly after sunset. Previously mentioned
deep south upper wave will bring some high clouds late, but
should be thin enough that they will have little bearing on
overnight lows. Look for low temperatures just slightly milder
than last evening, mainly in the upper 20s to low 30s
inland... Mid to upper 30s at the coast.

Short term 6 am Sunday morning through Tuesday
As of 355 pm est Saturday...

surface high pressure builds overhead Sunday. Continued quasi-
zonal, progressive flow aloft will bring another quiet, pleasant
day. Temperatures do moderate a bit more as winds do turn around
to the e-se. Despite the modest warm up, temperatures remain at
or just below climo norms. Highs again in the 50s to near 60
each day. Early morning lows ranging through the 30s to near 40.

A weak cold front approaches the region late Monday into Tuesday,
but with limited moisture and weak forcing to work with, not
expecting much of any precipitation across the region. Could see
a few sprinkles light rain along the albemarle sound Monday
morning, but chances of measuring precipitation occurring are
quite low, and have therefore kept pops at slight chance for
Monday. By late Monday, we will a better chance of some
scattered light rain showers mainly north of ric-sby line Monday
afternoon into Monday night... But again given rather shallow
overrunning, any QPF would be quite low, and have therefore kept
rain chances on the low side. Look for additional temp
moderation with temps warming out ahead of this system. High
temperatures Monday climbing up into the upper 50s to lower 60s.

Overall timing of front continues to slow with 12z 17 model run.

Blended model solution now favors the (mainly dry) frontal
passage now occuring into the aftn on Tuesday (ecmwf remains
fastest within the guidance envelope, with the remaining
guidance leaning toward slower gfs). Given the eps looking a bit
slower than the operational ecmwf, have again favored slowing
timing down slightly. Therefore kept warm side of guidance for
Tuesday with highs in the mid 50s to low 60s. Mainly dry w
majority of moisture forcing sliding off to our north.

Long term Tuesday night through Saturday
As of 400 pm est Saturday...

the medium range period looks to be relatively quiet with dry wx and
below normal temperatures through fri, then becoming unsettled by
next Sat as low pressure moves NE from the gulf of mexico. Latest
suite of 12z 17 models are in good agreement that a strong upper
level trough moves ese from hudson bay canada on Wed to the canadian
maritimes by 12z fri. Strong cold sfc high pressure (>1035 mb) will
build SE from the upper great lakes to the NE states on
thanksgiving, before settling from eastern ny state new england to
the mid-atlc by fri. After a dry cool but seasonal day on Wed with
highs in the upper 40s to mid 50s, temperatures really trend colder
for thanksgiving day and Fri with highs only in the 40s for the most
part even with ample sunshine. Lows will be mainly in the 30s wed
night, but down into the 20s for most of the region for thanksgiving
night Fri morning. By late Fri fri night into sat, the nw
flow confluent zone aloft shifts E off the new england coast and sfc
high pressure retreats to the ne. GFS is slowest to bring moisture
into the local area for sat, the gem ECMWF being a little faster.

Have gone with high chance to low-end likely pops by Sat aftn for
the piedmont with chance elsewhere. Highs will show the typical
cad wedge pattern, eventually reaching into the upper 50s to the
lower 60s over NE nc far SE va, while holding in the upper 40s lower
50s nw.

Aviation 21z Saturday through Thursday
As of 1250 pm est Saturday...

vfr conditions across area terminals this afternoon... With the
lone exception with some bay-induced MVFR CIGS across the
eastern tidewater area, which is bringing some sct-bkn
stratocumulus and high-end MVFR CIGS to korf and vicinity this
afternoon. Expect these clouds at ~2.5-3 kft agl to break within
the next few hours, with high confidence that dry,VFR
conditions will prevail through the 18z TAF period. Winds will
remain generally light and variable through the forecast period
away from the coast.

Outlook:VFR and dry conditions will continue through early next
week as high pressure builds across the region.

Marine
As of 400 pm est Saturday...

late this aftn, one area of high pressure was right over the
waters, while a second area was centered over WRN pa. The center
of that high will slide ene and off the new england coast
tonight thru thu. Northerly winds 5-10 kt late this aftn, will
become NE everywhere late tonight into Sun morning. Winds 5-10
kt become E then SE during sun, then sse becoming SW or W sun
night into Mon morning. A cold front moves through the area
tue morning, with the wind becoming NW then N 5-15 kt by tue
night. Strong high pressure builds N of the region late wed
night thru thu, resulting in increasing NW then N winds.

Hydrology
As of 355 pm est Saturday...

cancelled flood warning for lawrenceville. River flood warnings
remain in effect for mattoax on the appomattox, on the

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data.
