What forecasters said that day

The local office's own words before this dense fog advisory went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Philadelphia/Mount Holly wrote its last area forecast discussion before this dense fog advisory went out at Jul 3, 7:13 PM EDT, 6 hours 12 minutes earlier.

Area forecast discussion, Jul 3, 7:13 PM EDT, 6 hours 12 minutes before
Area Forecast Discussion
National Weather Service Mount Holly NJ
713 PM EDT Sat Jul 3 2021

.SYNOPSIS...
A strong upper level trough will move to the east of the area
tonight into Sunday. Weak high pressure will slide across the region
on Sunday. A warm front will lift north through the area on Monday,
followed by a cold front around midweek that stalls nearby through
the end of the week. The front may interact with possible remnants
of tropical cyclone Elsa later in the week.
&&

.NEAR TERM /THROUGH SUNDAY/...
This evening, the surface trough will slowly push east and
begin to wash out. As this occurs, shower and thunderstorm
coverage will wane. Lows will be below normal for the season,
with most areas outside of the urban centers falling below 60
degrees, with even some mid 50s towards the Poconos.

On Sunday, the upper level low will be slowly heading east with the
back side, ageostrophic convergence, of the low finally beginning to
approach the region. The reason for the slow departure, is the
second low located over Ontario/ Quebec will dive south on the back
side. This slow departure of the low means another day of showers (
and possibly an isolated rumble of thunder). Coverage will likely be
scattered in nature, but updrafts will be much shallower as mid-
level dry air rushes into the region. A warming trend will also
commence on Sunday as 850 MB temperatures recover towards 12 degrees
C (about 2 to 3 degrees warmer than today) with high temperatures
reaching near 80 degrees. By Sunday evening, any shower development
that has occurred will quickly weaken and diminish in coverage as
daytime heating is lost.
&&

.SHORT TERM /SUNDAY NIGHT THROUGH MONDAY NIGHT/...
The upper level low shifts further to the north and east of our area
by Sunday night and we should see things clear out pretty quickly.
Some clouds may linger for a bit Sunday night but most areas should
start to see clear skies develop. Overnight lows will drop into the
60s across much of the region with some places in the southern
Poconos and northwest New Jersey dropping into the mid to upper 50s.

A warm front will lift northward across the region on Monday and we
see our flow turn back to the southwest. This will start to usher in
some warmer (and more seasonable) temperatures. Daytime highs on
Monday will rise into the mid to upper 80s (cooler across the north
and along the immediate coast).

With the southwest flow, we will also start to see moisture increase
across the region once again. Dew points will rise from the more
comfortable upper 50s to lower 60s from the weekend back into the
mid to upper 60s on Monday.

While we should remain relatively dry across the forecast area on
Monday, there is the potential for a lee side trough to develop to
our west. We don't have much support for storm development but could
see some isolated showers or thunderstorms during the afternoon or
evening, mainly confined near the Poconos. Anything that does
develop will be diurnally driven and should taper off towards
sunset.

Light winds and mostly clear skies should lend itself to a nice
summer night across the area. Overnight lows will be in the upper
60s to lower 70s with some low to mid 60s across the northern
zones.

&&

.LONG TERM /TUESDAY THROUGH SATURDAY/...
The main story of the extended period will be a cold front dropping
down into our area around midweek and the potential interactions
with tropical cyclone Elsa.

On Tuesday, high pressure sets up over the Atlantic and should be
the main influence to our weather. The southwest flow will continue
to bring warm, moist air into the region and it will start to get a
bit sticky again outside. With 850mb temps back in the 18C-20C
range, expect that daytime highs will be reaching into the low to
mid 90s. Dew points rise back into the upper 60s to low 70s, which
will cause heat index values into the upper 90s to near 100. We may
need heat headlines for Tuesday and will need to monitor the trends
over the next couple of days.

Beyond Tuesday, there remains plenty of uncertainty as the front
drops down into our area. Just how far the front makes it into our
area will impact temperatures. Especially on Wednesday, when we
could still have heat concerns with highs in the 90s once again.
Additionally, the location of TC Elsa will need to monitored as we
could potentially start to see some affects from the system. Models
still don't have a great handle on these features and aside from the
fact that we will very likely have showers and thunderstorms through
the Wednesday/Thursday timeframe. So basically we have confidence
that we will be stormy but low confidence on the location of the
systems that will be impacting us. Again, this is another thing that
needs to be monitored over the coming days, especially as Elsa
starts to make her way towards the mainland.

With the lower confidence, have stayed close to the previous
forecast and introduced just a bit of the newer guidance blend.

By the end of the week, another upper trough starts to dig down from
Canada along with a surface cold front that may approach our area
over the weekend. Definitely not what we expect to see as we head
through July across the Mid-Atlantic.

&&

.AVIATION /23Z SATURDAY THROUGH THURSDAY/...
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG,
KMIV, KACY and surrounding areas.

Tonight... VFR conditions will start out this evening, before
MVFR conditions return on the back side of the departing upper
level low for most sites. There could even be some IFR at times
overnight. Winds generally light and variable. Moderate
confidence.

Sunday... Any MVFR conditions from the morning will quickly lift to
VFR as the boundary layer quickly mixes out. Another round of
scattered showers is possible Sunday afternoon, but coverage will
likely be less than Saturday. The chance of thunder also looks
pretty low at this time given the entrance of mid-level dry air to
sounding profiles. Winds will light and out of the west. High
confidence.

Outlook...

Sunday night...Mainly VFR. Light and variable winds. Moderate
confidence.

Monday...VFR. Light and variable winds becoming southerly around 5
knots. Winds will become more southwesterly overnight.
Patchy fog possible late. Moderate confidence.

Tuesday...Mainly VFR. Isolated showers and thunderstorms possible at
KABE in the afternoon/evening. Southwest winds around 5 to 10 knots.
Moderate confidence but low confidence on showers/thunderstorms.

Wednesday through Thursday...Showers and thunderstorms with sub-VFR
conditions possible at all terminals. Southwest winds around 5 to 15
knots. Low confidence.

&&

.MARINE...
Tonight... The Small Craft Advisory will expire at midnight as
seas fall to 3 to 4 ft. Winds will also become north-northwest
over all the waters as the weak surface boundary slowly washes
out. Northwest winds around 10 kts.

Outlook...

Sunday night through Monday...sub-Small Craft Advisory conditions
expected.

Tuesday...Wind gusts may near 25 knots and seas may near 5 ft,
mainly along the northern Atlantic waters. A Small Craft Advisory
may be needed.

Wednesday and Thursday...Sub-Small Craft Advisory conditions are
expected. Seas may start to near 5 ft Thursday afternoon.

Rip Currents...
For today, there is a moderate risk for the development of dangerous
rip currents due to N-NE winds 15-20 kt and seas building to 5 ft.

On Sunday, winds shift to the south and diminish to around 10 kt.
Seas subside as well. As a result, there will be a low risk for the
development of dangerous rip currents.

There is potential for an elevated risk of rip currents Wednesday
through Friday as tropical system Elsa could take a path off the
eastern seaboard.

.PHI WATCHES/WARNINGS/ADVISORIES...
PA...None.
NJ...None.
DE...None.
MD...None.
