Synopsis
A weak cold front will stall near or in the region today before
slowly shifting northward as a warm front tonight and Wednesday. A
lee surface trough will develop across the area on Wednesday ahead
of a slow-moving cold front, which will cross the area Thursday and
Thursday night. High pressure will gradually build into the area
this weekend into early next week.

Near term until 6 pm this evening
Patchy fog has been tough to form overnight as fairly thick high
level clouds moved across the area during the night. However, some
patchy areas of fog, especially ground fog, has developed and will
continue to develop through daybreak. Visibility is not very low for
most places, although a few spots could drop below one mile at
times. Any fog that does develop will lift and dissipate later this
morning.

A backdoor cold front dipped down across the area overnight and is
expected to stall out across the area through today. The exact
placement is to be determined, but most likely across southern new
jersey, across northern delmarva, and across southeastern
pennsylvania for much of the day. It will likely try to begin
drifting back northward later in the afternoon. Several short
wave vorticity impulses will move across the area within a weak west
to southwest flow aloft which will help lead to a chance of
scattered showers and thunderstorms this afternoon. CAPE values will
increase to at least 1,500-2,500 j kg across much of the area,
especially along and south of the frontal boundary. However, with
the weak flow aloft, shear is very minimal, not even reaching 20
knots. However, given the strength of the instability, some strong
updrafts will be possible, which could produce some stronger
downbursts as well as some hail. With pw values around 1.75-2.00
inches, any thunderstorms will be capable of producing heavy
rainfall as they will be efficient rain producers. Any storms will
likely be slow moving as well, so there will be the potential for
some areas of flooding.

Today will be another hot and humid day, although north of the
stalled out frontal boundary, dewpoints will likely be a couple of
degrees lower then south of the boundary. We have kept the heat
advisory for the urban corridor as some areas will approach or
exceed 100 degree heat index criteria.

Short term 6 pm this evening through 6 am Wednesday
The frontal boundary will continue to slowly drift northward
overnight tonight, but likely not fully clear the area by daybreak.

Multiple short wave vorticity impulses will move across the area
within the southwest flow aloft. This will help lead to a chance of
showers and thunderstorms through the night. There will also be the
chance for patchy fog overnight as well.

Long term Wednesday through Monday
Main forecast challenges revolve around storm chances through
the end of the week.

The setup continues to look quite favorable for a couple rounds
of storms Wednesday through Friday. Starting with Wednesday,
with the backdoor-cold-turned-warm front lifting north into new
england, a lee surface trough will become established across the
region during the day. Meanwhile, as a potent vort MAX pivots
southeastward into the great lakes, a predecessor perturbation
will eject east into far southeast canada and new england.

Large-scale ascent in advance of this perturbation should become
collocated with the prefrontal trough and the downstream warm
sector. Numerous storms are expected to develop by afternoon
from the northern mid-atlantic northeastward in an environment
characterized by 1500+ j kg MLCAPE and increasing deep-layer
shear. Our CWA will be on the southern fringe of both the
stronger shear and strongest large-scale ascent. Nevertheless,
the thermodynamic profiles are suggestive of fairly strong cold
pools developing with storms. Given the anticipated coverage of
convection, would expect storm organization to increase with
time even this far south given the favorable profiles for strong
cold pools. Latest convection-allowing model guidance depicts
storms congealing into line segments and affecting the northern
portions of the CWA by late afternoon evening. This seems
reasonable given the setup, though I suspect the model consensus
is a little too far north (as organized convection in these
regimes tends to develop southward into the reservoir of
instability more readily than models project at these time
ranges).

Given the uncertainty with the southern extent of the strongest
convection on Wednesday, did not want to get too specific with
threats in the public forecast (yet), and the inherited pop
forecast looked quite reasonable. The SPC day-2 convective
outlooks maintains a marginal risk for the northern half of the
area, with a slight risk touching the far northern portions of
the area. Clearly, this will be a period to watch for severe
potential. In addition, locally heavy rainfall is a concern
given high (1.75+ inch) pws and potential for slow storm motions
and or training convection.

By 00z Thursday, the aforementioned great lakes shortwave trough
will acquire a neutral tilt and begin lifting northeastward.

However, an upstream perturbation will dig southeastward into
ontario quebec on Thursday. This midlevel evolution should
result in strong cyclogenesis northeast of the great lakes
Wednesday night and Thursday, with a cold front moving toward
the east coast. However, this is where models noticeably
diverge. The 00z cmc digs this upstream perturbation into the
eastern great lakes and only gradually shifts it eastward Friday
and Saturday. This results in relatively little precipitation on
Thursday but quite a bit on Friday in our cwa. Meanwhile, the
00z GFS blasts this upstream perturbation through the northeast
on Friday, which results in most of the convection occurring on
Thursday afternoon evening before the front moves quickly
southward by Friday. The 00z ECMWF is somewhat middle-of-the-
road, though its more nebulous appearance to the upstream
perturbation is doubtful.

The bottom line is that the forecast for Thursday and Friday is
quite unclear. With frontal timing in question and its overall
trend appearing to be somewhat slower, I was inclined to keep
pops mentionable right through Friday in most of the area, with
a gradual trend downward from north to south. I am rather
concerned the GFS is much too quick in shunting the front precip
southward out of our area for Friday, especially given the
positively-tilted and amplifying ridging downstream of the
potent shortwave trough in the great lakes.

The environment downstream of the front will remain quite
unstable, and with a slowing cold front in the mix, locally
heavy rainfall is again possible.

Temperatures Wednesday and Thursday will remain warm hot, and
humidity will be oppressive. Quite confident heat advisory
criteria will be met again in the urban corridor, so have
extended the advisory through Wednesday. It is not out of the
question advisory conditions last into Thursday. As the cold
front continues south, Friday should be much cooler.

Eventually, high pressure should build into the northeast,
bringing an extended period of near-seasonal temperatures and
much lower dew points. Models are hinting at prolonged onshore
flow by the end of the weekend into next week, suggesting the
cooler spell may continue for a while. No complaints!

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

Today... After some morning light fog lifts and burns off, mostlyVFR
conditions will be in place across the area through today. There is
a chance of scattered showers and thunderstorms this afternoon, so a
prob30 group was added for the afternoon period. If a shower or
thunderstorm does occur, it could temporarily lead to lower
conditions. Winds will be quite variable for many locations for much
of the day as a back door frontal boundary will be stalled out across
the area. Any direction will most likely be from the south to
southeast, and wind speeds will be 5-10 knots or less.

Tonight... Tonight will start outVFR this evening across the area
outside of any afternoon evening showers or thunderstorms. However,
conditions are forecast to lower overnight as low clouds and or fog
are expected to develop during the overnight period. MVFR and ifr
conditions can be expected later tonight. There is also a chance for
showers and thunderstorms to develop overnight as well.

Outlook...

Wednesday and Wednesday night... PredominantlyVFR, but sub-vfr
conditions in showers storms possible at times, especially from
the philly terminals northward. South to southwest winds 5 to 15
kts.

Thursday and Thursday night... PredominantlyVFR, but sub-vfr
conditions in showers storms possible. Southwest to west winds
on Thursday becoming northwest Thursday night, generally around
or below 10 kts.

Friday and Friday night... Low-confidence forecast, with
showers storms possible, especially south of phl. Some
restrictions possible if precipitation occurs. Winds generally
north to northwest around or below 10 kts.

Saturday... MainlyVFR with light north winds.

Marine
Conditions will remain below advisory levels for today through
tonight. There is a chance for scattered showers and thunderstorms
which could temporarily lead to locally higher winds and waves.

Outlook...

Wednesday and Wednesday night... Conditions may approach advisory
levels, but are expected to remain generally below wave wind
thresholds. A chance of storms, with stronger winds and higher
waves possible in their proximity.

Thursday through Friday night... Sub-advisory winds seas
expected. A chance of storms through the period, with the best
chances gradually shifting southward through the period.

Saturday... Sub-advisory conditions expected. Cannot rule out
showers storms, especially off the delaware coast.

Rip currents...

with waves forecast at 2-3 foot and a 6-7 second period, along
with southerly winds 5-10 knots, the risk for dangerous rip
currents is low for today and tonight. Waves in the surf zone
will likely remain around 2-3 feet.

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

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

De... Heat advisory until 8 pm edt this evening for dez001.

Md... None.

Marine... None.
