Marine Weather and Tides
5/23/2017 - Worked with NOAA again to speed up the 7 day forecast load times. Thanks to them for being responsive.
5/19/2016 - There were issues with the 3 day airport observation history. I switched to another data source. Let me know if you see any issues with the data feeds.

445 am edt Mon may 29 2017
Low pressure located off the middle atlantic coast early this
morning will move farther out to sea today. Another weak low is
expected to follow along a trailing frontal boundary and it
should pass off the middle atlantic coast on Tuesday night. A
cold front is forecast to approach from the northwest on
Wednesday and it should pass through our region on Wednesday
night. Another cold front is anticipated to arrive on Friday
night or Saturday.
Near term until 6 pm this evening
Cloudy, showery, and cool conditions to start off the day
across the area, with a partial improvement possible later today
for some areas.
An area of low pressure located offshore of the mid-atlantic
this morning will continue to move eastward and away from the
area through today. The associated stationary boundary to our
south is forecast to remain to our south, while an approaching
occluded front will likely wash out and dissipate as it
approaches the area from the west this afternoon. High pressure
across the canadian maritimes will nose its way down the eastern
seaboard and keep a cool and moist easterly flow across the
Showers will continue to spread across the area through the
morning hours as a short wave vorticity impulse moves across the
area and interacts with the abundant mid-low level moisture. As
this short wave passes to our east, the showers will begin to
dissipate later this morning into the afternoon. The cloud cover
will have a chance to dissipate and break some by this
afternoon as well for a portion of the area, especially for
portions of the DELMARVA and southern new jersey.
Where clouds remain through the day, temperatures will likely
have a hard time rising, but if where any breaks of Sun occur
across the southern areas, temperatures will rise more. We used
a blend of available MOS and mosguide for daytime highs.
Short term 6 pm this evening through 6 am Tuesday
The aforementioned occluded front is expected to have
dissipated by this evening, while high pressure from eastern
canada continues nosing down the eastern seaboard. With an
easterly flow continuing across the area, this will keep cool
and moist conditions across the area through the night. It is
possible some isolated showers may develop overnight, but patchy
areas of fog and drizzle may also occur. Uncertain as how dense
fog will get because not much of the guidance gets visibilities
below 1-2 miles. So we will keep patchy fog and drizzle in the
forecast for now, but we are not expecting widespread dense fog
at this time.
Long term Tuesday through Sunday
A mid level low is forecast to meander over upper ontario and
vicinity during the mid week period before shifting eastward
over quebec and eventually atlantic canada during the weekend.
An initial mid level trough axis is expected to pass over our
region around Wednesday night with a secondary axis anticipated
around Saturday night. The pattern should be rather unsettled
with the best chance for dry weather extending from Wednesday
night into early Friday.
We are expecting Tuesday to begin with a low overcast in much
of eastern pennsylvania, new jersey and the upper delmarva. Some
fog is anticipated at that time, as well. A southeasterly
surface flow on Tuesday should keep the clouds from lifting and
breaking quickly. As a result, we are forecasting a mostly
cloudy day along with a chance of showers and perhaps some
thunder. High temperatures should be in the 60s up north and
right along the coast. Maximum readings are expected to be in
the lower 70s from the philadelphia metropolitan area southward.
The most likely area for a substantial break in the cloud cover
is southern delaware and the adjacent counties of northeastern
maryland. There the highs could reach the upper 70s.
A weak surface low is forecast to pass off the middle atlantic
coast on Tuesday night with partial clearing possible in its
wake for Wednesday. However, a cold front approaching from the
northwest along with some marginal instability may result in the
development of showers and thunderstorms mainly during the
afternoon and evening hours. The best chance for precipitation
at that time will be in eastern pennsylvania and northern new
The cold front is expected to pass through our region on
Wednesday night followed by dry weather and seasonable
temperatures for Thursday and Thursday night.
Another cold front is anticipated to approach from the|
northwest on Friday and it should pass slowly through our region
on Friday night and Saturday. We will mention another chance
for showers and thunderstorms in advance of the front.
The southward progress of the front over the weekend is a low
confidence forecast. The models differ on how progressive the
boundary will be. As a result, we will keep a chance or slight
chance of showers into Sunday.
Aviation 09z Monday through Friday
The following discussion is for kphl, kpne, kttn, kabe, krdg,
kilg, kmiv, kacy and surrounding areas.
An easterly flow will continue through today across the area as
low pressure moves out to sea, and high pressure noses down the
eastern seaboard across the area. This will keep plenty of
moisture low level moisture across the area through today. Ifr
conditions are expected to continue through much of the day,
with showers through this morning as well. However, there is a
chance for some improvement late this afternoon into this
evening. Even if this improvement does occur, clouds are
expected to fill back in overnight with low clouds and fog
developing again, leading to ifr conditions overnight. There is
also the possibility for patchy drizzle to develop overnight as
Tuesday... Ifr conditions in the morning improving to MVFR and
vfr during the course of the day. A chance of showers and
Tuesday night and Wednesday morning... Conditions may lower back
to MVFR and ifr for a time.
Wednesday afternoon and evening... MainlyVFR with a chance of
showers and thunderstorms.
Wednesday night through Friday morning... MainlyVFR.
Friday afternoon... MainlyVFR with a chance of showers and
Small craft advisory continues across the northern half of the
atlantic coastal waters through this morning as seas are
expected to build to around 5 feet and winds could gust around
25 knots. Conditions are expected to fall back below advisory
levels this afternoon. The rest of the waters are expected to
remain below advisory levels through tonight.
Tuesday through Wednesday... Wind speeds and wave heights are
forecast to remain below the small craft advisory criteria.
However, some fog is possible on the waters.
Wednesday night through Friday... No marine headlines are
the potential for the development of dangerous rip currents is
low for today.
Tides coastal flooding
Tidal departures of around 1 foot are expected again tonight for
coastal areas of new jersey and delaware and areas along
delaware bay. These tidal departures would lead to another
round of minor coastal flooding for tonight's high tide.
Therefore we've issued a coastal flood advisory for tonight.

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.
