Synopsis
Low pressure moves across new england today. Another low will
move through on Friday. A cold frontal passage occurs late
Saturday, cooling things down for Sunday and Monday. A warming
trend will then occur for the first few days of may.

Near term until 6 pm this evening
The fcst is on track. Upper shortwave passes across new
england, and sfc low moves to the north. Westerly winds behind
this low will prevail, with a few gusts to 20 to 25 mph possible
during the day. Northern locations may see a few more clouds
due to upper shortwave proximity.

Based on forecast profiles, and mixing depth, expect highs in
the mid to upper 60s, with a few 70s possible. In some cases,
these forecast temps are slightly higher than a MOS blend.

Short term 6 pm this evening through 6 pm Friday
Weak ridge briefly builds ahead of next southern stream
shortwave, and downstream northern stream shortwave. Mainly
clear skies initially tonight will give way to increasing high
level clouds. Sfc high builds, allowing for light winds.

Temperatures tonight should range from the lower 40s interior
to the lower 50s across nyc metro.

Next low pressure approaches from the southwest ahead of
approaching trough, and another round of rain is expected from
mid late morning through the remainder of the day. Onshore flow
ahead of the low will result in cooler temps in the mid 50s to
around 60.

Long term Friday night through Wednesday
The rain will taper off Fri ngt with the models in good
agreement. A blend was used for the various data fields. A cold
front then approaches for sat. The trend is slower with the
shrtwv coming down from canada. As a result, the FROPA looks to
take place Sat ngt, with a slower progression of the upr trof on
sun. There should be a 6-12 hour window of dry wx after the fri
ngt rain and ahead of the cold front. Right now this looks to
be Sat mrng. However, this far out a blended approach was used
to compensate for potential timing changes. End result is low
chcs Sat mrng. These could be reduced in subsequent fcsts as
confidence increases. Some sct shwrs look to occur INVOF the
front. With the timing ATTM lining up with the overnight, llvl
instability will be weaker. With the upr low and cold pool
lagging behind on sun, extensive CU development is likely,
leading to bkn-ovc skies. Lake moisture should enhance the cloud
cover across the interior. The modeling now indicates
significant cloud cover hanging in Sun ngt, reducing the low
temp potential. Highs on Sun will be 5-10 degrees blw avg, so
the clouds may inhibit a widespread frost freeze situation at
ngt. Heights will begin to increase on mon, allowing for highs
to approach normal lvls. Ridging then develops between a pacific
trof and the upr low exiting the northeast. This will produce a
warming trend thru at least wed, bringing the 70s and low 80s
to the area.

Aviation 12z Thursday through Monday
Low pressure tracks into the canadian maritimes by Thursday
evening.

Any lingering lifr ifr CIGS and vsbys will lift between 12-13z.

Otherwise,VFR through the TAF period.

Light and variable winds becoming w-nw increasing to 10-15 kt
during the morning push. Wind gusts of 15-25kt develop after
12z. Winds back to the wsw-sw at kjfk and kisp this afternoon,
remaining W to wnw elsewhere. Wind gusts should abate late
Thursday afternoon early Thursday evening.

Ny metro enhanced aviation weather support...

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.
