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.

Low pressure and its associated fronts will affect the area tonight
through Sunday. An upper trough will move across the area Sunday
night. High pressure will build in for Monday and remain into
Wednesday. The high will move offshore later Wednesday allowing a low
and warm front to approach the area. Unsettled conditions expected
for the later part of next week.
Near term until 6 am Sunday morning
Winds continue to suggest that the warm front is south of
philadelphia. The Sun has appeared across portions of the delmarva.
This has pushed temperatures into the 80s. Further north, where
skies remain cloudy and winds from the ne, temperatures have
remained in the 60s all day. It's still in the upper 50s across
portions of the poconos.
As mentioned, there is some clearing across the delmarva. This
should advance across the nj coastal plain. Some peaks of Sun could
sneak into the souther portions of the i95 corridor, and adjacent
areas to the west, before sunset.
Model solutions remain vastly different on how they handle the warm
front tonight. Decided to stick closer to the NAM and keep the front
within the CWA through the night. We don't see it tracking north out
of our cwa. The NAM has it hung up trenton south much of the night.
Since temperatures never rose to expected levels this afternoon
across the northern half of the cwa, there won't be much variation
going into tonight. Further south, where the Sun has made an
appearance this afternoon, we will see temps drop diurnally. Looking
at 60s for the northern 2 3rds of the cwa, and lower 70s across the
southern 1 3rd.
Going with the more pessimistic NAM and keeping clouds in all night.
Best chance of precip tonight will be across the poconos and lehigh
valley area, and across the delmarva. Philly south is still outlooked
with a slight chance of severe, but feel this will be more confined
to our most southern zones. I trimmed pops back across our northeast
Short term 6 am Sunday morning through 6 pm Sunday
The warm front doesn't quite make it up to nyc. A cold front passes
around daybreak. Another cold front will try to push through Sunday
afternoon, but should be weakening as it does so.
Temps will climb into the 80s for most of us tomorrow. The poconos
will likely hold onto the 70s.
Maybe a bit more Sun tomorrow, but don't foresee the very low
clouds, fog, and drizzle the region is experiencing today. Chance
pops are in place mainly from the i95 corridor westward, slight
chance pops are in place across the coastal plain. The exception is
the poconos where I did paint likelies. The beaches may not see any
precipitation until the evening.
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 20z Saturday through Thursday
The following discussion is for kphl, kpne, kttn, kabe, krdg, kilg,
kmiv, kacy and surrounding areas.
Rest of afternoon early evening... Mainly ifr MVFR conditions. Light
ne winds except for kmiv and kacy. As the warm front pushes north of
these two terminals, S winds will develop.
Tonight... Ifr conditions expected from kilg north and westward. MVFR
expected for kmiv and kacy with the warm front moving north of these
Sunday... Mainly MVFRVFR with SW winds developing.
Sunday night... Sct evening showers then fair withVFR.
Monday thru Wednesday...VFR expected.
Wed night and Thursday... Sct tstms with restrictions psbl.
Tonight... I have dropped the SCA and capped seas at 4 ft. Winds
should hold on 10 kt or less across our northern waters. This will
transition into some gusts up to 20 kt well south adjacent to akq. A
few tstms possible across the delaware and nj coastal waters this
evening. Because of the warm front, monmouth county winds should
stay NE much of the night. Further south, they should go s.
Sunday... SCA not expected. SE to SW winds 10 kts or less. Seas 3 to
4 ft on the ocean and up to 2 feet across de bay.
northeasterly-easterly winds will shift to the south-southwest
tonight, except for monmouth county. Speeds will mainly be 10 kt or
less except for the delaware beaches where some gusts up to 20 kt
are possible. Seas in the surf zone will be 3 to 4 ft. There is a
low risk for the formation of dangerous rips this evening for the de
beaches. With more of an onshore component of flow and swell, there
is a moderate risk for the nj beaches.
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

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.
