Synopsis
Low pressure over northern new england continues lifting into
the canadian maritimes today. High pressure builds in for the
rest of the week, followed by a frontal system over the weekend.

The front will usher in colder air for the beginning of next
week.

Near term until 6 am this morning
Upper low and associated surface low continue to deepen while
lifting up into the canadian maritimes. Cold advection on the
backside of the system will usher in cooler air on gusty west
winds early this morning. Broken stratocu attempted to move into
the NW interior, has struggled to persist mainly due to
downsloping. Model soundings do show increasing moisture between
800 and 900 mb towards day break, so have followed a trend
towards a scattered to broken cloud deck at that time for the
western half of the area. There still is some uncertainty on the
extent of these clouds.

Lows will remain well above normal, in the lower to mid 30s,
but relatively cooler.

Short term 6 am this morning through 6 pm Thursday
A secondary cold front passes through in the morning. High pressure
will build east from the mid section of the country while low
pressure tracks northeast across the canadian maritimes.

Nearly seasonable weather will follow for Wednesday and
Wednesday night with continued cold advection and winds veering
to the nw. It will remain gusty during the daytime hours up to
about 25 mph, then diminish in the evening.

Highs will be slightly above normal in the upper 30s to lower
40s, with near normal lows ranging from the mid teens inland, to
the lower 20s at the coast.

Long term Thursday night through Tuesday
The 12z GFS and ECMWF are beginning to come together on a soln for
the weekend frontal sys. Because of this, a blend of the 2 models
was used for temps, with a broad blend of raw model data used for
pops. This breaks down to low chcs for lgt rain Sat aftn, with rain
chcs increasing Sat ngt and likely rain on sun. As the front comes
thru, there could be a quick changeover to snow, primarily away from
the coast, Sun ngt. The models however are still not very robust
with pcpn on the back side of the sys. For mon, the colder air flows
in with a chc for rain and snow shwrs into Mon ngt. Dry thereafter.

Otherwise, high pres builds in this Thu and fri. Dry wx was fcst as
a result. The superblend was used for temps except for Thu ngt due
to the position of the high. With lgt winds, the fcst there is a
blend of guidance to better capture radiational cooling, a few to
several degrees blw the superblend.

Aviation 06z Wednesday through Sunday
A secondary cold front approaches from the northwest early this
morning, then pushes southeast through the area by early
afternoon. Canadian high pressure then builds down from the
northwest into tonight.

Vfr through the TAF period.

W-wsw winds around 10-15kt early this morning, with some gusts to
around 20-25kt, mainly at city terminals. Winds then veer to the wnw
by mid morning with gusts 20-25kt. Winds veer to the NW by
early evening, with gusts abating mid-late evening.

Outlook for 06z Thursday through Sunday
Wednesday night-Thursday Vfr. NW winds g15-20kt possible.

Thursday night-Saturday Vfr. SW winds g15-25+kt possible Saturday.

Saturday night-Sunday MVFR or lower possible with showers. Llws
possible Saturday night. W-nw winds g20-30kt possible Sunday.

Marine
On the heels of a cold front passage, winds may briefly drop
this evening before strengthening again. SCA w-nw gusts in the
25 to 30 kt range are expected tonight into Wednesday on all
waters. Winds should gradually fall below SCA late Wednesday
into Wednesday night, with ocean seas following suit.

Winds and seas will creep up towards SCA lvls on Thu as low
pres deepens over the atlc. Winds and seas blw SCA lvls on fri,
then SW flow increases over the weekend ahead of a frontal sys,
with SCA cond likely Sat and Sun on the ocean, and possible
elsewhere.

Hydrology
No significant hydrologic issues are anticipated through next
week.

Nyc NOAA weather radio station kwo-35 (162.55 mhz) is off the

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.
