Synopsis
High pressure builds over the region today before sliding
offshore tonight. A warm front will approach on Thursday and
move across the area Thursday evening, followed by a cold front
Thursday night. High pressure returns to the region for Friday.

A frontal system will pass through the region Saturday into
Sunday. A stationary front will set up south of the region
Monday with a wave of low pressure passing through Monday night.

High pressure returns for Tuesday and Wednesday.

Near term until 6 pm this evening
A strong ridge continues to build into the region from the west
through today. The ridge was keeping cirrus from spilling over,
and high clouds will likely be delayed from moving into the
region. Only minor adjustments were made to the winds,
temperatures and dew points through this morning.

High pressure remains over the region today. It will be dry and
comfortable with just high level clouds as the ridge axis
remains to our west.

Light northwest winds will turn southwesterly during the day,
with sea breezes developing along the immediate coast. Temperatures
will be a few degrees warmer than yesterday, in the upper 60s
to lower 70s.

Short term 6 pm this evening through 6 pm Thursday
The upper ridge will begin to flatten tonight as surface high
pressure moves offshore and a weak wave approaches. Winds will
continue to turn more southerly as the high slides east,
allowing a return to warm air advection and increasing clouds.

Temperatures Wednesday night will be close or a few degrees
warmer than normal.

A few showers are possible Thursday morning associated with
weak shortwave energy but with subsidence associated with the
offshore high, the best chances for showers will be across new
jersey and the lower hudson valley.

A warm front will then slowly lift out of the ohio valley
Thursday afternoon and with strong southerly flow, dewpoints
will rise into the 50s to lower 60s by late afternoon. Daytime
highs will rise into the 70s away from the coast, and in the
upper 60s across long island and southern connecticut.

Long term Thursday night through Tuesday
An upper level northern stream shortwave will be moving into a
sub tropical ridge centered across the southeastern states
Thursday night with a surface warm front passing across the
region Thursday evening. The area will become warm sectored with
dew points rising into the lower 60s, mainly inland. Then with
the shortwave passing to the north Thursday night a cold front
will drop south, and through the area. With some destabilization
and low CAPE of 300 to 500 j kg, along with a 40-50kt jet
passing through, scattered thunderstorms are possible with the
potential for isolated severe thunderstorms, mainly across
northeastern new jersey and into the lower hudson valley. A few
stronger storms may move into southwestern connecticut and into
western long island, however the storms will be moving into a
more stable environment. Gusty winds will be the main threat
into Thursday evening and added this enhanced wording.

The upper shortwave moves through the ridge by 12z Friday and
heights will begin to rise as the sub tropical ridge builds back
into the great lakes and upper midwest.

Some uncertainty with the timing and placement of the next
shortwave moving through the northern stream develops Saturday
into Sunday as this energy will be associated with an upper
closed low opening and moving out of the west coast Friday. This
shortwave will also be moving into the eastern sub tropical
ridge, and may move more to the north than currently forecast.

So will have slight and chance probabilities into Sunday night.

Again, the ridge builds back into the area into Wednesday before
a deeper shortwave moves out of the west and potentially phases
with a northern stream shortwave, bringing a chance of
precipitation late Wednesday. At this time, with high
uncertainty as to timing and placement will leave next Wednesday
dry.

Aviation 12z Wednesday through Sunday
High pressure builds into the region thru Wednesday.

Vfr through the TAF period.

Light NW winds mainly around 10 kt this mrng. North winds
increase slightly 10-15 kt thru 14z. Winds eventually shift to
the south, due to high pressure passing southeast and seabreezes
developing. Light and vrb or SW flow tngt, with SW flow
increasing thru the day on thu.

Ny metro enhanced aviation weather support...

NOTE: East coast views moved to GEOS-16. They are experimental and not well supported by NOAA so they may not be correct so be warned. This change required redoing a large amount of the GOES code. If the image you are expecting is not showing, please let me know. You may need to use the EDIT function to update your location.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
