Version 3.4
What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

Synopsis
High pressure retreats to the northeast as warm front approaches
from the southwest through Saturday. The front lifts to the north
Sunday, followed by a cold front in the afternoon to evening hours.

High pressure then builds through mid week, giving way to a warm
front Wednesday night into Thursday.

Near term until 6 am Saturday morning
Surface ridging holding on this evening, which is aiding in
diminishing any light showers that approach from the south and
west. A few locations have reported trace amounts from
sprinkles. Next batch of showers across nj should follow the
same pattern and dissipate as it moves into the surface ridge
through midnight.

The surface ridge axis lifts to the north and east as the warm
front approaches after midnight. Guidance continues to differ
with the timing of the onset of the measurable rain, but the
emphasis continues to be towards daybreak. The best chance of
showers is across the southwestern portion of the region,
gradually spreading northward. Much of eastern long island and
southeast connecticut should remain dry through the night due to
the proximity of the ridging and drier low level air. Instability
is weak and will therefore leave out the mention of any thunder
overnight.

Lows will be near seasonable levels in the lower 60s with
easterly winds.

Short term 6 am Saturday morning through Saturday night
Showers and isolated thunderstorms are likely in the morning
with the best thermal forcing ahead of the filling upper low
moving into the eastern great lakes. Warm front continues to
approach with an easterly flow through the day, veering around
to the southeast toward evening. The activity will likely
dissipate in coverage late morning and into the afternoon with
the potential for a long break. However, the associated upper
trough will move across the area in conjunction with the warm
front toward the late afternoon early evening. This combined
with increasing elevated instability will result in another
period of widespread showers and scattered thunderstorms.

Locally heavy downpours will also be possible with precipitable
water values approaching 2 inches.

The warm front may get up as far as long island Saturday night
with the showers exiting late in the evening.

Highs on Saturday will only be in the lower 70s due to cloud
cover, rain, and easterly flow.

Lows Saturday will be mild with the warm front in close
proximity.

There is a moderate risk of rip currents at atlantic ocean
beaches on Saturday.

Long term Sunday through Friday
A weak low pressure system shifts through the northeast on Sunday
with a cold front moving through during the afternoon to evening
hours. Expecting at least scattered showers and thunderstorms during
this period with the highest overall chances occurring north of the
city. High temperatures will be above normal.

High pressure builds in during Monday, but with a cyclonic flow
aloft there could be a shower or two across SE ct. Partly cloudy
with near normal temperatures. The high pressure center moves
through on Tuesday with sunny conditions and highs close to normal.

The high will be to our east on Wednesday, and a return SW flow will
bring warmer and more humid conditions. It appears the daytime hours
for most areas will be dry as showers ahead of an approaching warm
front remain to the west. The warm front moves through, then a cold
front slowly approaches Thursday into Friday. Timing of the cold
front is not certain, so will go with slight chance to chance pops
Wednesday night through Friday. Rising temperatures aloft will allow
for highs in the 90s for the city and some inland areas Thursday and
Friday. If the cloud cover is lower then currently anticipated, then
highs could be a even a few degrees higher than what's in the
forecast.

Aviation 02z Saturday through Wednesday
High pressure off the northeast coast and extending into new
england will drift east through Saturday as a warm front and low
pressure area approach. The warm front will likely remain to
the south of the terminals through 00z Sunday. There is a low
chance the front moves through late in the forecast period.

Vfr with periods of MVFR ceilings as stratus moves through the
terminals. A few light showers will be possible. Late tonight
light showers will become widespread along with MVFR
conditions, lowering to ifr and possibly lifr toward Saturday
morning. A brief improvement to MVFR is possible during Saturday
afternoon.

A rumble of thunder will be possible with the showers Saturday,
with the best chance of thunder late in the afternoon into the
evening.

Se wind backs to E to NE tonight and then winds remains NE to e
through Saturday until the warm front approaches late Saturday.

Winds will be 10 to 15 kt along the coast and 5 to 10 kt
inland.

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.
