Synopsis
Low pressure will track out to sea today, allowing high pressure
to build in on Thursday. Low pressure will impact the area
Thursday night through Saturday. High pressure builds in for
Sunday through Monday night. Another area of low pressure
affects the region Tuesday.

Near term /through tonight/
High pressure continues to build southward into the region
today. The high, combined with an exiting low pressure system
will produce northerly winds into tonight. Expect mostly sunny
skies today with just some fair weather cumulus this afternoon
as convective temperatures are reached. Moderate mixing will
allow for temperatures to eclipse highs of the past few days,
despite the essentially cooler airmass. The guidance was in good
agreement so a blend was used.

Short term /Thursday/
High pressure drifts across the forecast area resulting in fair
weather and light winds. Mid and high clouds will filter out the
sunshine from time to time. A blend of the guidance, which was
in good agreement, was used for temperatures.

Long term /Thursday night through Tuesday/
Operational models are in fairly good agreement in the long term.

High pressure at the surface pushes off the new england coast
Thursday night. Warm air advection allows clouds to lower and
thicken, with precipitation moving in mainly late Thursday night as
a weakening surface low form the mid-west approaches. Precipitation
may start out as a brief period of wintry mix inland. Little, if any
accumulation is expected.

Precipitation continues into Friday, with plain rain everywhere by
the afternoon. The rain may come down moderate to heavy at times
Friday night as a secondary low develops off the mid-atlantic coast,
creating a decent amount of lift throughout the column to support
the heavier rainfall. Precipitable water values exceeding an inch
late Friday night is well above the average for the date, given
climatology.

After some lingering showers Saturday morning, surface high pressure
builds in thereafter, keeping the area dry through the rest of the
weekend into Monday.

High pressure pushes off the east coast on Monday night, allowing for
another low to affect the area Tuesday.

Temperatures during the long term will be seasonable, with the
exception of Friday and Saturday. Cloudy skies and rain will keep
temperatures below normal these days.

Aviation /18z Wednesday through Monday/
A cold front pushes through the region this afternoon followed
by high pressure building towards the area tonight.

MainlyVFR conditions are forecast through the TAF period.

Lingering pockets of MVFR at kgon will diminish by 17z.

Nw gusts of 20-25 kt likely into the afternoon, but there could
be a few hours where gusts weaken or drop off. These gusts may
return late afternoon into early evening, lasting at metro
terminals through 00-02z, diminishing 00 to 02z. Winds expected
to be right of 310 magnetic through the period.

Ny metro enhanced aviation weather support...

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.
