Synopsis
Weak backdoor front will slip south into the area late tonight
and Sunday. A weak upper level disturbance will cross the area
Sunday night. A warm front will lift north across the region
Monday. A cold front will drop south across the region Tuesday
night. High pressure will dominate Wednesday and Thursday.

Near term until 6 am Sunday morning
High pressure dominates at present, centered to the south, but a
cold front is slowly slipping toward us from the north. The
front will drop into the region late tonight, but with limited
if any sensible weather impact. High pressure will be the true
dominating factor in the weather tonight, with radiational
cooling allowing temps to drop back below freezing in most
areas. Winds will lighten quickly after sunset.

Short term 6 am Sunday morning through Monday night
Backdoor front stalls out in the area Sunday before essentially
dissipating. Thus, temps on Sunday, while starting chilly,
should not be significantly different from today. However,
clouds will be increasing ahead of a weakening shortwave which
is currently over western texas. The clouds will move in, but
the rain will be falling apart as the shortwave rides over the
top of a ridge to our south and forcing falls apart. Temps will
be marginal, so will have to look for potential mixed precip at
elevation and at night, mainly along the fringes of the cwa
(allgheny front and mason-dixon line), but right now it looks
like impacts will be minimal.

Warm front lifts north Monday with temps rising into the 50s
most areas. Upslope showers may linger along allegheny front,
but most areas dry. Staying mild at night with lows above
freezing most spots.

Long term Tuesday through Saturday
Split upper level flow will be in place during the middle of
the week. Tuesday will likely be mild (50s to perhaps lower 60s)
if not a bit cloudy in between northern and southern stream
systems with a light southwest surface flow. Trough axis from
northern stream system will drop through the area by Tuesday
night, although it will be dry outside of a little upslope snow.

Wednesday could be breezy in the wake of the trough, and
temperatures will return closer to normal.

The 12z model suite is in a bit better agreement with keeping a
southern stream low pressure system suppressed to the south
(i.E., carolinas) Wednesday afternoon and night. With that said,
forecast QPF is close enough to central va that it will bear
watching since precipitation could take wintry form.

High pressure slides across the great lakes toward new england
Thursday into Friday. The high eventually becomes in a position
favorable for cold air damming, although at this time there
aren't any strong indications of clouds or precipitation, as a
subtropical ridge encroaches on the southeastern states. This is
subject to change pending any weak waves. Temperatures should
remain fairly close to normal.

The next upper trough will push toward the east coast Friday
into Saturday. This is the time period where guidance begins to
deviate the most since the northern and southern streams could
eventually phase. Meanwhile the subtropical ridge could attempt
to stay dominant to the southeast. Precipitation chances will be
increasing since the associated cold front could be slow
moving. Precipitation types could eventually become tricky over
parts of the area depending where the baroclinic zone settles
and if additional energy rides along it. Overall not looking at
any major blasts of cold air within the forecast period though.

Aviation 20z Saturday through Thursday
Vfr likely through Monday night. Main concern is isolated
showers late Sunday Sunday night which could drop CIGS and vis.

Winds will drop off quickly this evening and stay fairly light
through Monday night.

Vfr is anticipated for Tuesday through Thursday at the moment,
although a low pressure system won't be too far away to the
south on Wednesday that is worth watching. Northwest winds could
gust to 25 kt on Wednesday behind a low pressure trough.

Marine
Sca remains in effect at present, but winds should drop off
quicly this evening and stay fairly light through Monday
night,so no plans for additional sca's at present.

Southwest winds will begin increasing Tuesday. A trough of low
pressure will cross Tuesday night, with winds becoming
northwesterly and increasing further. A small craft advisory
will be possible through Wednesday. Lighter winds can be
expected Wednesday night into Thursday as high pressure builds
into the area.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
