Synopsis
Drier air works into the region behind a cold front overnight.

Blustery, dry and colder weather follows Wednesday through
Friday, then a warming trend next weekend. A cold front may
bring showers next Sunday or Monday.

Near term until 6 am Wednesday morning
Will continue to dry out lower to middle portions of the
atmosphere overnight as northern stream shortwave trough axis
pivots tot the northeast, with quasi-zonal flow setting up
aloft. As a result, expect a decrease in cloud cover overnight
and any fog, mainly over higher elevations, to dissipate by
shortly after midnight.

Otherwise... Low temps by daybreak will fall back into the upper
20s to the middle 30s.

Short term 6 am Wednesday morning through 6 pm Wednesday
Wednesday...

a west northwest flow of more seasonable temperatures will be
working back into the region on Wednesday. High temps will not
recover too much... Generally remaining in the 30s to near 40 across
parts of the coastal plain. Should be at least partial
sunshine... But do expect some strato-cumulus clouds that will be
focused across the interior. West to northwest winds will gust to
between 25 and 30 mph at times.

Long term Wednesday night through Tuesday
Highlights...

* dry but cooler weather for the rest of the work week
* above average temperatures for Saturday and Sunday
* next shot of wet weather will be around Sun mon
overview...

12z guidance is in general agreement with the upcoming medium and
long range. Progressive pattern over the region as ongoing upper
level trough will push offshore as mid-level ridge builds into the
area by the weekend. For the end of the period, still some
uncertainty regarding the timing and amplitude of the upper level
trough moving from the northern plains towards the east coast sun
into Monday. GFS continues to be on the faster side of the envelope
compared to the ec and ukmet. If the guidance continues to trend
towards the slower envelope, than there is the potential for a more
significant surface low to develop. This could result in warmer
temps for the weekend, and heavier rainfall. If it is weaker, than
cannot rule out some trapped cold air resulting in p-type issues.

Still a lot of uncertainty and will trend towards a blend of the
guidance until details can be sorted.

Wednesday night into Friday... High confidence.

Building high pressure across the southeast will build across the us
east coast resulting in dry weather through the period. Still some
thermal gradients in the mid-levels as upper level shortwave passes
through on Thursday. This will result in a breezy but chill day.

Temperatures will still be in the 30s on Friday, but with less winds
should make it feel warmer. Some mid-level moisture around 850-700mb
will help bring in some clouds but overall a pleasant january day is
on tap.

Saturday into Monday... Moderate confidence.

Subtropical ridge will build across the us east coast over the
weekend as northern stream system approaches the northeast. All
guidance as well as the ensembles are indicating precipitation for
the area. Biggest uncertainty is the amount, exact timing and if
all precip will be liquid. Current forecast is an ongoing blend of
the guidance with a trend towards the UKMET and ec. Thus expect
precipitation to move into the area on Sunday as mostly rain and
temperatures will be well above average thanks to southerly llj.

If precip lingers into Monday, CAA behind the system could switch
any precip to snow, but overall confidence is low that this will
occur. Will need better guidance to see this potential.

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.
