Synopsis
A warm front will gradually approach today before lifting
through the region tonight. A cold front passes through
Saturday with unsettled weather remaining through the weekend.

High pressure briefly returns early next week.

Near term until 6 pm this evening
Updated forecast to mention isolated to scattered shower
activity associated with the passage of a warm front today. The
rain will remain very light and will not be continuous.

Otherwise, the rest of the forecast is mainly on track. Not
anticipating much change with timing of warm front so kept the
max temperature forecast today the same as previously forecast.

High pressure retreats off the east coast as a warm
front gradually approaches the region today. While the front
will likely not lift north of the area until tonight, the warm
advection could generate some light rain showers or drizzle.

Southeast flow will strengthen during the day, with gusts up to
25 mph possible, especially along the coast.

Temperature forecast will be somewhat tricky as guidance
continues to about a ten degree spread in highs, likely due to
the differences in cloud cover and fog. Temperatures could be
higher than forecast if there is less cloud cover, and a few
degrees cooler if more fog develops.

Short term 6 pm this evening through Saturday
The warm front will lift north tonight, and with prolonged
onshore flow, low levels should remain saturated enough to keep
a chance of light rain or drizzle in the forecast.

The region will remain in the warm sector with temperatures
staying in the 50s overnight.

Attention then turns to a slow moving cold front which will
impact the area Friday into Saturday. Friday will start off with
areas of fog and drizzle which will linger through the morning
especially across the coast. Steady rain will move in Friday and
continue through much of Saturday.

Deep moisture will stream northward with precipitable water values
between 1.5 and 2 inches. Rain will be heavy at times especially
overnight Friday into Saturday morning. SPC has placed the
region in a general risk, therefore have included slight chance
of thunder. Gusty winds up to or around 45 mph could occur
especially in any thunderstorm where stronger winds could mix
down.

The cold front will then exit the area sometime Saturday
evening though there is still some uncertainty as to what time
it fully clears the area. This will keep a chance for rain
showers through Saturday.

Long term Saturday night through Wednesday
There will be the associated parent low that will be moving
northward and weakening into Saturday night. The low will bring
a surface trough towards the region but will dissipate before
moving across the local region. This will keep a chance for rain
showers going Saturday night and even Sunday as aloft the upper
level low will be moving across.

The upper level low moves east of the region early next week
with a weak pressure gradient at the surface. High pressure
stays mainly north of the region early to middle of next week.

There will be occasional chances of rain showers but chances are
lower without as much time duration and not much in the way of
heavy rain with the showers. Much of the time early to mid next
week could very well stay dry.

Temperatures will remain above normal. Highs are forecast mainly
in the 60s except N W of nyc in lower 70s Friday and Monday.

Friday night lows are forecast in the upper 50s to lower 60s.

The lows forecast Saturday night, Sunday night, and Monday night
are in the upper 40s to lower 50s. The lows Tuesday night next
week are forecast to be in the mid 40s to near 50.

Aviation 14z Thursday through Monday
A warm front slowly approaches and lifts north of the region
today.

Conditions will continue to lower to MVFR this morning as a
warm front approaches. Light rain and drizzle will be possible
along with a chance of ifr conditions. Winds will be from the se
10-15kt with gusts around 20kt.

There could be a period of fog this afternoon, especially east
of the nyc terminals, which lowers visibilities to 1 mile or
less.

Uncertainty remains with how far north the warm front is able to
lift this afternoon evening. Current thinking is that the front
will lift far enough north of the terminals for conditions to
improve toVFR this evening. However, if this does not occur and
the front remains over the region, expect MVFR ifr for much of
the TAF period.

Llws develops for the eastern terminals around 00z.

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.
