Nor'easter conditions subsiding some later tonight and
Friday...

Near term (through Friday) strong surface high centered along
the mid atlantic region will slightly weaken and shift east by later
tonight and Friday. Winds will decrease some beginning tonight as
the gradient relaxes some. Breezy conditions still expected along
the coast tonight and Friday. A mid/upper ridge builds into the area
Friday bringing decreasing clouds and slightly drier conditions.

Short term /thru Saturday night/
Upper ridge centered along southeast u.S. Coast while strong upper
system moves across south-central u.S. Fri night and sat. Surface
high remains offshore of the mid-atlantic states. Dry and mild
conditions with high temps Sat in the mid 70s coast... Upr 70s-lwr
80s further inland... And low temps in 55-60 range.

Long term /Sunday thru Thursday/
Upper system lifts NE toward great lakes region Sunday. GFS suggests
some showers in our area during the day Sunday... While ecm is dry.

Lack of dynamics to support more substantial precip leads me to keep
pops low for widely scattered sea breeze convection Sunday. Warm
temps Sun with highs upr 70s coast... Lwr-mid 80s inland... And lows
sun night upr 50s-lwr 60s.

Aviation PrevailingVFR cigs. There may be brief periods of
MVFR cigs. Gusty northeast winds will tend to decrease some during
the overnite hours.

Marine Strong high pressure north of the waters weakens
some and shifts east the next few days. Small craft advisory in
effect for all the waters through Friday morning and for the
offshore through early Saturday morning. Winds decrease further and
veer to southeast over the weekend but seas will probably remain
elevated enough offshore for cautionary headlines.

Rip currents: high risk through Friday. Elevated risk likely into
the weekend.

Fire weather Elevated dispersions expected this afternoon and
again Friday. Breezy conditions today... With lighter winds Friday
and the weekend.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
