Synopsis
High pressure in southern canada will build towards the region
today before cresting over new england on Wednesday. Another
area of low pressure crosses the region Thursday night into
early Friday. It will be seasonably mild, but unsettled through
the weekend.

Near term until 6 pm this evening
Low pressure will intensify as it exits through the canadian
maritimes today. Meanwhile, high pressure will begin to build
into the region from canada. This will set up a strong west to
northwesterly gradient over the region today which deepens
through a significant layer this afternoon. Expect wind gusts to
around 40 mph, however they may potentially go slightly higher
during the late afternoon hours.

Despite the strong cold air advection, downsloping will allow
for temperatures to climb into the 60s over southern areas. It
will be somewhat more chilly in the north where a cyclonic flow
will allow for plenty of cloudiness, especially over the
northwest facing higher terrain. Steep low level lapse rates and
sufficient moisture will allow for scattered showers in the
north today as well.

Short term 6 pm this evening through 6 pm Wednesday
Wind profiles MAX out aloft this evening. However, mixing
heights will gradually lower this evening as well.

High pressure will then crest over the region on Wednesday. Will
the surface gradient will become light, winds aloft will likely
mix down to the surface, making for a somewhat breezy day. Winds
may attempt to come onshore along the coast in the afternoon.

Long term Wednesday night through Monday
Ensemble and deterministic model solutions remain in good agreement
on the long wave pattern through late in the upcoming weekend. The
forecast period begins with an upper trough closed low over the
western CONUS and a building ridge downstream over the southeastern
conus. While the ridge will briefly build north across the area
at times... The real heat and humidity remains to our south as
passing shortwave impulses riding along the periphery of the ridge
have a tendency to flatten it. With the mean jet position
nearby... We'll see quick day-to-day changes in the sensible
weather as weak systems continue to traverse the region. For a
change... Temperatures will average close or slightly above normal
for the period as cold air remains bottled up well to our north.

In the dailies... A ridge of high pressure retreats offshore
Thursday. Low pressure and a trailing frontal system approach from
the great lakes for Thursday night and Friday. A weak ridge of
high pressure and drier air will briefly follow Friday night and
early Saturday. Another frontal system will cross the area late
Saturday and Saturday night. A weak cold front will cross the
region on Sunday.

Aviation 07z Tuesday through Saturday
Short term... MainlyVFR conditions through the period. However,
mountain showers and cloud cover will lead to MVFR conditions
over northern and western portions of the forecast area.

Long term...

thu night - fri... Areas of MVFR in -shra.

Sat pm... Areas of MVFR in -shra -tsra.

Marine
Short term... A west to northwesterly gradient will increase and
deepen allowing for gusty winds today and tonight. Scas will

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.
