Marine Weather and Tides
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 for the long island waters and new york harbor.. A warm front will remain to the south overnight as a wave of low pressure moves east along it. The front will then lift to the north on Sunday, followed by a cold frontal passage Sunday afternoon and evening. High pressure will then build in through mid week, giving way to a warm front Wednesday night. A weak cold front will then approach on Thursday.

932 pm edt Sat jun 23 2018
Low pressure and its associated fronts will affect the area through
Sunday. High pressure builds in Monday and Tuesday, then it moves
offshore later Tuesday into Wednesday. A warm front moves to our
north Wednesday night, then a cold front slowly approaches Thursday
Near term until 6 am Sunday morning
A warm front is draped roughly from far southeastern new jersey
across DELMARVA then west-northwestward into central pennsylvania.
This front looks to very slowly migrate northward through the night,
however it may not get passed the delaware valley. The low-level
flow is rather weak, however an east to northeast component is
continuing north of the warm front. This is keeping lots of low
clouds in across much of the area with only some improvements across
the far southern areas where more of the warm sector has arrived.
Even into parts of DELMARVA though some low clouds have expanded
southwestward some, and there looked to be an outflow boundary that
slid southwestward across southern delaware earlier. Overall, lots
of clouds are expected for much of the region through tonight, and
with increasing low-level moisture combined with warming above the
lingering marine layer, patchy fog is anticipated. Given the cloud
over though, widespread dense fog is not expected.
Some short wave energy is moving across the area this evening, and
there is some semblance of a very weak surface low in northeastern
maryland. Given lingering instability across the southern and far
western areas, some showers and perhaps a few thunderstorms are
anticipated into the overnight. As we get beyond midnight,
confidence lowers regarding the shower potential as there does not
appear to be much present to provide a focus. As a result,
maintained continuity with a dry forecast later tonight.
The hourly temperature, dew point, pops, sky cover and wind grids
were all updated based on the latest observations and trends.
Short term 6 am Sunday morning through 6 pm Sunday
A warm front should make it into our far northern areas. A
dissipating cold front passes around daybreak, however the main cold
front arrives during Sunday afternoon. Temperatures will climb well
into the 80s for most. The poconos will likely hold onto the 70s.
More sunshine is anticipated Sunday after the day starts with low
clouds and perhaps some fog. Chance pops are in place mainly from
the i-95 corridor westward, slight chance pops are in place across
the coastal plain. The exception is the west northwest zones where a
period of likely pops occurs in the afternoon. Farther south and
east, the convective potential may not occur until later in the
afternoon. The beaches actually may not see any precipitation until
the evening. The forecast soundings indicate with ample boundary
layer heating, an inverted-v signature develops in the afternoon.
This may assist in locally gusty winds with any stronger convective
Long term Sunday night through Saturday
Sunday night... The last of the showers from Sunday will end from nw
to SE during the evening as the cold front upper trough move east of
the area. Skies should become partly cloudy overnight and low
temperatures will drop into the 60s in most areas. A bit warmer
across DELMARVA and perhaps some upper 50s across the southern
Monday thru Wednesday... Three nice days expected with only a small
chc for a TSTM across the N W areas Wednesday afternoon. It will be
pleasantly mild and comfortable with highs generally in the
low mid 80s. These readings are within a few degrees of normal
for late june. High pressure will predominate, cresting over the
area Tuesday and moving offshore Wednesday.
Wednesday night thru Saturday... Unsettled conditions along with|
a change to hot and humid conditions expected. Highs on
Thursday may remain in the upper 80s, but 90s are expected
Friday and into the upcoming weekend. Plenty of humidity is
expected as well. Temperatures and humidity levels will likely
fall into excessive heat criteria if things don't change. This
will be worth watching over the next few days. A low pressure
system and associated fronts will affect the area from Wednesday
night thru Friday, we we have some chc pops for tstms in the
fcst for those periods.
Aviation 02z Sunday through Thursday
The following discussion is for kphl, kpne, kttn, kabe, krdg, kilg,
kmiv, kacy and surrounding areas.
Tonight... Ifr MVFR ceilings overall. Some showers around through
about 05z, however the thunder chance is rather low. Winds mostly
light and variable, and some local fog is possible overnight. Lower
confidence regarding the ceiling heights trends and extent of any
Sunday... Ifr MVFR to start, then improving toVFR by 15z. Some
afternoon showers and thunderstorms are anticipated, especially
north and west of phl. Light and variable winds, becoming southwest
around 10 knots.
Sunday night... Sct evening showers then fair withVFR.
Monday thru Wednesday...VFR expected.
Wed night and Thursday... Sct tstms with restrictions psbl.
The conditions are anticipated to be below small craft advisory
criteria through Sunday. Winds should hold at 10 knots or less
across our northern waters. This will transition into some gusts up
to 20 knots for the delaware atlantic coastal waters. A few
thunderstorms possible through this evening mainly from about
atlantic city southward where locally gusty winds are possible.
Because of the warm front, the winds across the far northern
waters should stay northeast much of the night. Further south,
they should go southerly. For Sunday, southeast to southwest
winds 10 knots or less. Seas 3 to 4 feet on the ocean and up to
2 feet across delaware bay.
sun night... Lingering showers or tstms will end overnight, sub-
sca conditions, but higher winds and seas near any tstm. Monday
thru Wednesday... Sub-sca conditions with fair weather. Wednesday
night thru Thursday... Low end SCA conditions with sct tstms.
for Sunday, there is a low risk for the development of dangerous rip
currents at the new jersey and delaware beaches due to more of a
south to southwest wind.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
