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 located in central ontario early this morning
will build to the southeast. The center of the high is forecast
to pass off the coasts of southern new england and long island
on Tuesday. The air mass is expected to influence our weather
into early Thursday. A weak frontal boundary approaching from
the west is anticipated to arrive in our region on Thursday.

Another area of high pressure should follow for Friday and the
coming weekend.

Near term until 6 pm this evening
The pattern today reminds me more of a pattern we would see in
late april, not late june. Behind the cold front that arrived
last evening, high pressure will build south form canada through
the day. As it does so, the pressure gradient will slowly relax
through the day. With the high building in, expect dry
conditions through the day.

There are two uncertainties with our forecast today, the sea
breeze and the depth of the mixing layer. A sea breeze should
develop this afternoon, but due to the relatively strong
northwesterly flow, do not expect the sea breeze to make much
progress inland, possibly staying right along the coast.

The question is the depth of the mixing layer. With this
similar pattern in the spring, models tend to underestimate the
depth of the mixing layer. Consequently, depicted dew point
temperatures are often too high, and depicted temperatures are
often too low. However, since this is an unusual pattern for
this time of year, I don't have as much confidence that these
biases will be true today. Therefore, I stayed close to the
warmest and driest guidance for temperatures and dew points
today.

Short term 6 pm this evening through 6 am Tuesday
As the pressure gradient continues to decrease, and with the
loss of diurnal mixing, winds will subsequently decrease as
well. This, along with the clearing skies, will set the stage
for prime radiational cooling conditions. With the dry air in
place, minimum temperatures could be 5 to 10 degrees below
normal.

Long term Tuesday through Sunday
A mid level ridge is forecast to extend from the southeastern
states up over ontario on Tuesday morning. The feature will
progress eastward with its axis expected to pass overhead on
Tuesday night. Surface high pressure is anticipated to pass off
the coasts of southern new england and long island on Tuesday.

The air mass should bring dry conditions to our region for
Tuesday and Tuesday night.

A mid level trough is expected to extend from the great lakes
down to the middle mississippi river valley on Wednesday
morning. The trough is forecast to move to the east and it
should pass over our region on Thursday. As the trough
approaches, we are anticipating an increasing chance of showers
and thunderstorms on Wednesday and Wednesday night. The
potential for showers and thunderstorms will continue into
Thursday as a surface front associated with the mid level
feature arrives in our region. Precipitable water values are
expected to increase to greater than 2 inches, so there is the
potential for some locally heavy rain at that time.

Heat and humidity will be on the increase for Friday, Saturday
and Sunday. A mid level ridge is forecast to build eastward from
the lower ohio river valley on Friday. It is expected to settle
over our region for Saturday and Sunday, limiting the potential
for precipitation even as the heat and humidity levels rise. It
appears as though heat index values will be near or a bit above
100 on Saturday and Sunday.

Aviation 07z Monday through Friday
The following discussion is for kphl, kpne, kttn, kabe, krdg,
kilg, kmiv, kacy and surrounding areas.

Today...VFR conditions are expected with few, if any clouds.

Winds, westerly early this morning will slowly shift to
northwesterly this morning. Gusts to 20 kt are possible this
afternoon. The one caveat is that a sea breeze is expected to
develop this afternoon. However, due to the relatively strong
northwesterly flow, do not expect this sea breeze to reach even
acy. Moderate confidence on the sea breeze, high confidence on
all other aspects of the forecast.

Tonight...VFR conditions will continue. Winds will slowly shift
from northwesterly to northeasterly, but wind speeds after
sunset should be less than 10 kt. High confidence.

Outlook...

Tuesday and Tuesday night... MainlyVFR. East wind less than 10
knots becoming southeast.

Wednesday... MainlyVFR. A chance of afternoon showers and
thunderstorms. Southeast wind around 10 knots becoming south.

Wednesday night... Showers and thunderstorms are likely.

Conditions are expected to lower to MVFR and perhaps to ifr at
times. South wind 5 to 10 knots.

Thursday... Conditions varying from MVFR toVFR with a chance of
showers and thunderstorms. Southwest wind 5 to 10 knots.

Thursday night and Friday... Late night and early morning
visibility restrictions are possible, otherwise mainlyVFR. West
wind 5 to 10 knots becoming northwest.

Marine
Winds and seas are expected to remain below small craft
advisory criteria. However, northwesterly gusts near 20 kt will
be possible, especially this morning.

Outlook...

Tuesday through Wednesday evening... No marine headlines are
anticipated.

Late Wednesday night through Thursday evening... Wave heights on
our ocean waters may build around 5 feet due to a persistent
southerly wind.

Late Thursday night and Friday... No marine headlines are
anticipated.

Rip currents...

the risk for the formation of dangerous rip currents is
forecast to be low today thanks to offshore winds (with the
exception of a weak sea breeze for a period this afternoon) and
wave heights 2 ft or less.

The wind is forecast to become onshore around 10 mph on
Tuesday. However, a medium period swell should keep the risk
for the development of dangerous rip currents at low for
Tuesday.

Phi watches warnings advisories
Pa... None.

Nj... None.

De... None.

Md... None.

Marine... None.

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.
