Synopsis
A strong ridge of high pressure will build over the region through
the weekend. An extended period of excessive heat is expected.

A strong and slow moving cold front will approach by Monday.

This front will likely move offshore by Tuesday. High pressure
with dry and much cooler weather should build in from the west
by the middle of next week.

Near term until 6 pm this evening
A subtle frontal boundary meandered from the poconos down to
northern delaware before curving back to the central part of the new
jersey coast then out over the ocean around 3:30 am. There was a
sizable area of low clouds extending from near the boundary well to
its northeast. The low clouds will linger until after sunrise, when
they should begin to lift and gradually dissipate. The front should
become more difficult to locate at that time. From about 9 or 10
o'clock onward, the sky over our region should be mostly sunny.

Today's main weather concern is the increasing heat along with the
high humidity levels. The excessive heat warning remains in place
for all of eastern pennsylvania, new jersey, delaware and
northeastern maryland. Maximum temperatures are forecast to be
around 90 degrees in the elevated terrain of the poconos and far
northern new jersey, as well as along the immediate coast. Highs are
expected to be mostly in the middle 90s elsewhere in our region. Dew
point readings in the lower and middle 70s will produce heat index
values as high as 102 to 107 during the afternoon.

The wind should settle into the southwest around 5 to 10 mph.

Short term 6 pm this evening through 6 am Saturday
Showers and thunderstorms are expected to affect the great lakes
region today, before moving farther eastward late in the day. Some
of the showers and thunderstorms may brush across the poconos, and
parts of the lehigh valley and northern new jersey this evening.

Otherwise, we are anticipating partly cloudy, warm and humid
conditions in our area for tonight.

The wind is forecast to be light and variable with low temperatures
ranging mainly from 75 to 80 degrees.

Long term Saturday through Thursday
Overview...

all indications remain on track for a prolonged, dangerous, and
potentially deadly period of excessive heat for our area over the
weekend. An expansive ridge extending from the south central states
out into the western atlantic will yield near record warmth for
multiple days. Saturday and Sunday will both see heat indices in
excess of 100 degrees, potentially as high as 115 degrees on
Saturday. Heat related illnesses and death can occur in minutes on
days such as these in cases of over-exertion or entrapments in hot
vehicles. Because of this, extreme caution should be exercised over
the weekend with regards to the heat.

A cold front, signaling a pattern change, will slowly approach by
Monday and into Tuesday. During the air mass transition, a period of
thunderstorms with heavy rainfall is possible. In addition to the
flooding potential, there may be a severe weather risk with this
activity as well. By the middle of next week, an entirely different
pattern takes shape over the conus. After the frontal passage Monday
night or Tuesday, a robust trough digs in over the east, with strong
ridging over the mountain west. This will yield much cooler and
drier weather as we head towards the middle of next week, bringing
welcome relief from the heat.

Dailies...

Saturday-Sunday... Blistering heat. No significant changes in terms
of the temperature forecasts. Saturday's highs were nudged down just
a degree or two, with Sunday's inched up a degree or so. The result
is both days now look to have very similar high temperatures in the
upper 90s, though Saturday still has the highest heat indices, up to
115 in the urban corridor but with widespread values over 105. These
heat index values come down about 5 degrees Sunday but remain in
very dangerous territory, around 100 to 110. In addition, another
important consideration is the overnight minimums, especially
Saturday night when most places won't fall below the mid 70s and
some urban areas will not go below 80. This will make for very
little overnight relief. Was not going to quibble on headlines; will
keep a blanket excessive heat warning for all areas through Sunday.

Saturday looks to stay dry though cannot completely rule out a pop-
up storm especially to the west. By Sunday, showers and
thunderstorms may approach from the west as a front begins moving
towards the area, though there are some indications this may hold
off until later. If storms move in a bit sooner, which is looking
more unlikely at this point, high temperatures may be over-done by a
couple degrees. Given high heat and humidity, any storms could
produce locally heavy rainfall.

Sunday night-Monday night... This will be our transition period. A
strong but slow moving cold front will be approaching from the west.

The air mass ahead of it will be very moist, with pwats coming back
up to around 2.25" or higher after easing back a little on Sunday.

As the front crawls through, it looks like one or more waves of low
pressure may develop along it. There is definitely a risk for heavy
rainfall and flash flooding over this period especially if we do get
multiple rounds of convection as new waves of low pressure develop.

In addition, given the tropical air mass expected Monday, it is
possible if not likely that some new heat headlines will be needed,
though cloud cover will keep the highs about 10 degrees cooler than
Sunday. Depending on the speed of the front, cooler air may start to
filter in by Monday night.

Tuesday-Thursday night... Welcome relief. A much cooler, much drier
air mass settles in. In fact, Tuesday and Wednesday are likely to
have below average temperatures area wide! A lingering shower is
possible Tuesday especially over DELMARVA and coastal nj. Otherwise,
most of this period should be dry, though an afternoon shower or
storm is possible by Thursday as an upper level disturbance
approaches. Highs generally in the low to mid 80s with comfortable
dewpoints in the low to mid 60s, so this looks like a really nice
stretch, certainly compared to the ongoing heat.

Aviation 08z Friday through Tuesday
The following discussion is for kphl, kpne, kttn, kabe, krdg, kilg,
kmiv, kacy and surrounding areas.

Today... Ifr and MVFR conditions through about 13z, the becomingVFR.

Variable wind 5 knots or less becoming southwest 5 to 10 knots.

Tonight... MainlyVFR. Variable wind 5 knots or less.

Outlook...

Saturday-Saturday night... GenerallyVFR. MVFR is possible due
to visibility restrictions in haze on Saturday. West-southwest
wind 5 to 10 kt.

Sunday... MainlyVFR but MVFR possible in haze. Afternoon and
evening showers and thunderstorms possible especially near and west
of phl. Westerly wind 5 to 10 kt.

Sunday night-Monday night... Widespread showers and thunderstorms
with associated MVFR and ifr conditions. Westerly winds becoming
northwesterly at 5 to 10 kt.

Tuesday-Tuesday night... Lingering MVFR possible Tuesday morning,
but should trendVFR with a light north or northeast wind.

Marine
A variable wind 10 knots or less this morning is forecast to settle
into the south and southwest 10 to 15 knots during the afternoon and
into tonight.

Wave heights on our ocean waters are expected to be 2 to 4 feet.

Waves on delaware bay will likely be 2 feet or less.

Outlook...

winds and seas are expected to remain below SCA criteria through the
outlook period.

Rip currents... A light and variable wind this morning should
become southerly around 10 to 15 mph in the afternoon. Breaking
waves around 2 feet are expected along with a medium period
south to southeast swell. As a result, there should be a low
risk for the development of dangerous rip currents for today.
