Synopsis
A weak cold front will move into the region tonight. The front
stalls near our area through Tuesday before moving northward on
Wednesday. A stronger cold front will drop down into the area
Wednesday night and then slowly sag southward through Thursday. Low
pressure will track along the slow moving front on Thursday. High
pressure will then build down from the northwest on Friday and
persist through the weekend.

Near term until 6 am Tuesday morning
Still a few showers across NE md this evening where some
residual heat and humidity remains from earlier today. A weak
front will drift across the area overnight. Patchy low clouds
are possible overnight as well as some fog, especially in areas
that received rain. Few changes to temps winds were needed from
earlier.

Short term 6 am Tuesday morning through Tuesday night
The flow aloft Tuesday is forecast to be more zonal, however a short
wave trough which looks to be convectively enhanced is forecast to
be approaching the upper ohio valley later in the afternoon. This is
pretty much tracking along a west to east weak cold front that
should become nearly stationary across our area. This will result in
some cooling and also lowering dew points along and north of it,
however how far south the lowered dew points get is more uncertain.

As a result for now, we will continue with the heat advisory Tuesday
for the urban i-95 corridor from trenton to philadelphia to
wilmington however this is of lower confidence given much of the
guidance is cooler (some lower dew points).

For the convective potential, some showers and thunderstorms are
expected to develop mainly from mid-afternoon onward near and south
of the stalled front. There looks to be a light northeast to
southeast surface flow, and this may help to keep much of the
convective development south and just west of our area for much of
the day. As a result, made some adjustments to the pops to reflect
this idea. The severe thunderstorm risk looks low as it appears we
would have to wait for any organized storms to arrive from the west.

The SPC currently has a marginal risk for severe thunderstorms from
berks county southward to portions of delaware and marylands eastern
shore.

For Tuesday night, an incoming short wave trough that looks to be
convectively enhanced will near closer. Some downstream warm air
advection and also isentropic lift over a lingering surface front
may help so develop or sustain some convection. The chance of this
looks to be the highest across the northern zones and the higher
pops were placed there. Low temperatures are mainly a continuity and
mos blend.

Long term Wednesday through Monday
Unsettled pattern continues through Thursday before high pressure
builds in across the eastern us.

On Wednesday, the back door frontal boundary that stalls near the
area Tuesday is forecast to return northward as a warm front early
in the day. Some showers will be possible early in the day as the
front lifts northward, but the better chance of showers and
thunderstorms will be during the afternoon as a couple of short
waves vorticity impulses aloft interact with a lee-side thermal
trough that remains across the mid-atlantic region. It will remain
quite warm and humid, with temperatures several degrees above normal
and dewpoints in the upper 60s and lower 70s, so there will remain a
fair amount of instability across the area with CAPE values reaching
1,500-2,000 j kg. Bulk shear is not overly impressive at 25 to 30
knots as mid level winds are fairly weak. Nevertheless, there will
remain a chance for some of the strongest updrafts to produce
locally damaging winds and large hail. SPC has our area outlined in
a marginal risk for severe weather. Another concern on Wednesday
will be the threat for heavy rainfall. Pw values reach 1.75-2.00
inches and storm motions do not appear to be very fast so any
thunderstorms will likely be efficient rain producing storms and
could cause flooding concerns. The shower and thunderstorm activity
is expected to diminish overnight Wednesday as daytime instability
wanes and the short wave vorticity impulses from the afternoon
passes eastward.

A cold front is forecast to move into the area late Wednesday night
into early Thursday, before sliding eastward through the day. As the
day wears on, instability will build ahead of the cold front, while
shear begins to increase. There will be a chance for some strong
thunderstorms to develop, which could produce strong winds and hail.

Heavy rain will continue to be a concern as pw values increase to 2+
inches, so any storms that develop will likely be efficient rain
producing storms. The storms will likely continue for eastern areas
as the front progresses eastward, but as the front moves offshore,
showers and thunderstorms will come to an end.

The forecast for Friday remains uncertain as differences continue
between the GFS and ecmwf. The GFS pushes the front far enough south
to keep the area dry, while the ECMWF has the front stalling just to
our south with an area of low pressure moving along the boundary.

This would bring a period of rainfall to much of the area Friday.

The previous model run of the ECMWF had the front and low, but not
as far north but still had some precipitation for parts of the area.

For now, we will keep a chance of showers and thunderstorms for the
southern half of the area due to the uncertainty.

Saturday through Monday are expected to stay dry. High pressure
builds across the northeast and mid-atlantic region on Saturday,
then builds to our northeast on Sunday and moves offshore on Monday.

As the high builds offshore, there may be an increase in cloud
cover, but conditions are expected to remain dry across the
forecast area.

Temperatures for Friday through Monday are expected to be below
normal and dewpoints will be much lower than the next few days.

Aviation 01z Tuesday through Saturday
The following discussion is for kphl, kpne, kttn, kabe, krdg, kilg,
kmiv, kacy and surrounding areas.

Overnight...VFR outside of any lingering showers this evening,
then some local stratus and or fog cannot be ruled out overnight.

Light westerly winds or light and variable calm.

Tuesday... Local MVFR early due to possible fog, otherwiseVFR. Some
showers and thunderstorms are expected in the afternoon into the
overnight, resulting in temporary MVFR ifr conditions. Light winds
becoming northeast to east then southeast 4-8 knots during Tuesday,
then becoming light and variable at night.

Outlook...

Wednesday through Wednesday night... GenerallyVFR conditions
expected. MVFR or lower possible in showers and thunderstorms. South-
southwest winds around 5 to 10 knots with gusts up to 20 knots
possible.

Thursday through Thursday night... GenerallyVFR conditions expected.

MVFR or lower possible in showers and thunderstorms. West-southwest
winds around 5 to 10 knot veering to the west-northwest later in the
day and overnight behind a cold front. Winds could gust 15 to 20
knots behind the cold front overnight at times.

Friday...VFR conditions expected. Northwest winds around 5 to 10
knots may gust 15 to 20 knots at times.

Saturday...VFR conditions expected. Northerly winds less than 10
knots.

Marine
The conditions are expected to remain below small craft advisory
criteria through Tuesday night. A wind shift from southerly to
northeast and east will occur overnight into Tuesday, before
shifting southeasterly.

Outlook...

Wednesday through Wednesday night... Conditions expected to remain
below advisory levels, although winds could gust around 20 knots and
seas approach 4 to near 5 feet at times.

Thursday through Thursday night... There is a chance winds and waves
may approach advisory levels for the southern new jersey and
delaware coastal waters Thursday into Thursday night. The rest of
the waters are expected to remain below advisory levels.

Friday through Saturday... Conditions are expected to be below
advisory levels on Friday and Saturday..

Rip currents...

a low risk for the development of dangerous rip currents continues
through tonight with southerly winds and waves around 2 feet in the
surf zone.

For Tuesday, a low risk is anticipated once again despite a
northeast wind becoming east to southeast.

Phi watches warnings advisories
Pa... Heat advisory until 8 pm edt Tuesday for paz070-071-102-104-
106.

Nj... Heat advisory until 8 pm edt Tuesday for njz015-017>019.
