Synopsis
High pressure will remain over the region through 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. High
pressure builds back on Wednesday.

Near term /until 6 am Thursday morning/
High pressure continues to build to the north overnight.

Scattered clouds, and continued winds late this evening and
possibly into the overnight will have an impact on overnight
lows. Assuming north winds of at least 5 kt continue, ideal
radiational cooling may not occur. Raised lows slightly in
spots. Overnight lows will range from the upper 30s to the upper
20s.

Short term /6 am Thursday morning through Thursday night/
High pressure drifts across the forecast area on Thursday,
resulting in fair weather and light winds. Expect mid and high
clouds to move in from the west during the afternoon and
evening. A blend of the guidance, which was in good agreement,
was used for temperatures.

Clouds continue to thicken and lower Thursday night as low
pressure approaches the region. Pops gradually increase
overnight. Will cap pops at high chance for now. Precipitation
will generally be plain rain, however a wintry mix may be
possible across the lower hudson valley and connecticut.

Temperatures on Thursday will only reach the upper 40s and
lower 50s. Lows Thursday night will fall into the 30s.

Long term /Friday through Wednesday/
Low pressure system will track east on Friday. As this storm
approaches, precipitation will spread across the area from west to
east. Rain may come down moderate to heavy at times Friday into
Friday night as a secondary low develops off the mid atlantic
coast. This storm may produce anywhere between 1 to 1.5 inches
of rainfall from Friday into Saturday morning. While there could
be some urban and poor drainage nuisance flooding, impacts on
rivers and streams is not expected.

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 moves offshore 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.

Aviation /02z Thursday through Monday/
High pressure builds in through Thursday with low pressure
approaching Thursday night.VFR conditions are expected through
the TAF period.

The gusts to near 18-22 kt with the N flow will be slow to
subside this evening but most gusts are expected to be before
05z. Some locations could see gusts drop off for one hour and
then redevelop the next hour. Winds drop to 10 kt or less
overnight with sea breezes developing Thursday afternoon with
wind speeds remaining below 10 kt. Some interior terminals will
have winds become light and variable in direction Thursday.

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.
