Area forecast discussion, May 20, 1:59 AM EDT, 1 hour 16 minutes before
Area Forecast Discussion
National Weather Service Mount Holly NJ
159 AM EDT Fri May 20 2022

.SYNOPSIS...
A weak disturbance approaches late tonight and passes through
our area on Friday, then Bermuda high pressure sets up for the
weekend. A cold front passes through Sunday night and remains
nearly stationary over the Mid-Atlantic into next week. High
pressure passes to the north as the week progresses, then a
cold front approaches late next week.

&&

.NEAR TERM /THROUGH TODAY/...
Low temperatures should range from the low 50s north of I- 80
to the mid 50s to low 60s elsewhere. Winds will become light and
variable to even calm in many places. Patchy fog is expected to
develop this morning, particularly across coastal areas of New
Jersey and into interior portions of northern and northeastern
New Jersey. Confidence is low on how expansive and dense the fog
may become.

Another shortwave trough and an associated MCV complex from the Ohio
Valley are expected to progress toward the region overnight. The
approaching wave will lift a more pronounced warm front north
through the area during the morning hours Friday. Temperatures,
dewpoints, and thus instability will rise as the front lifts through
the area as the day progresses. Meanwhile, the broad synoptic
ridging will begin quickly building throughout the day and will
continue building through Friday night.

The latest CAM guidance suite indicates a wide variety of
outcomes related to how the remnant MCV progresses across the
region from the mid-morning and into the afternoon on Friday.
The strengthening ridge axis across the East Coast and western
Atlantic introduces a complex and low predictability scenario.
It seems that the strengthening ridge axis may be enough to
weaken/dry out the MCV or even push it north of the local
forecast area (into northeastern Pennsylvania and Upstate New
York). However, if the MCV slows down overnight and passes
across the region after daytime heating has allowed instability
to build, we could see a few thunderstorms become strong to
locally severe. In any case, the probability of convection has
undoubtedly increased enough to warrant a wholesale update and
increase to the PoPs/weather forecast for the daytime period.

Aside from the convection potential on Friday, skies should start
out partly cloudy. The cloud cover will be more widespread if the
MCV holds together or restrengthens across the region. Any lingering
fog should mix out fairly quickly. Southerly winds will increase to
10-15 mph. Expect highs about 10 degrees above normal in the mid to
upper 80s in most areas.

&&

.SHORT TERM /TONIGHT THROUGH SUNDAY/...
Weak low pressure passes north of the region Friday evening.
Any showers or thunderstorms should be over prior to sunset.
Meanwhile, Bermuda high pressure sets up off the Mid-Atlantic
coast with strong mid-level ridging along the Eastern Seaboard
and developing surface ridging as well.

Warm air and moisture advection will be underway Friday night.
Surface dew points climb into the mid and upper 60s through the
night. With sea surface temperatures still in the upper 50s to
around 60, can expect advection fog to form over the ocean and
to spread into coastal areas Friday night through Saturday
morning. Any fog on land should burn off with heating of the day
shortly after sunrise on Saturday.

A hot and humid air mass will be over the area this weekend,
but the hottest day will be Saturday. With abundant sunshine and
850 mb temperatures upwards of +20C, high temperatures away
from the coasts will climb into the mid and upper 90s. Surface
dew points will start out in the mid and upper 60s, but should
mix out into the low to mid 60s by Saturday afternoon. There is
not much wind aloft, and mixing does not look to be all that
impressive, so not expecting dew points to crash. Regardless,
the Heat Index will generally be in the mid to upper 90s, and
around 100 along the Urban corridor and into portions of
northeast New Jersey. For Delmarva and extreme southeast New
Jersey, Heat Index values have to be over 105 for a Heat
Advisory. It does not look as if the Heat Index will be quite
that high in those areas, so any Heat Advisories will be limited
to the Urban corridor and portions of northern New Jersey.
Along the coasts, highs will top off in the upper 70s to low
80s.

A warm and humid night is on tap for Saturday night. Some mid-
level shortwave energy approaches from the west in the afternoon
and evening, but will ride around the apex of the high. Any
convection should stay well north and west of the local area
during that time. Coastal fog redevelops Saturday night as
moisture advection continues and surface dew points rebound into
the mid and upper 60s.

A cold front begins to approach on Sunday. Clouds will spread
into the region ahead of the front, and the hottest air of the
air mass will push offshore. As a result, high temperatures will
be several degrees cooler compared to Saturday, generally in
the upper 80s to low 90s inland and in the 70s along the coast.

On Sunday, the cloud cover will help keep dew points elevated
in the afternoon. As a result, although surface temperatures
will be cooler compared to Saturday, the Heat Index will be high
once again. Max Heat Index values will be in the low to mid 90s
throughout, and in the mid to upper 90s along the Urban
corridor. A more localized Heat Advisory may be needed for
Sunday.

Surface high pressure sags a bit to the south on Sunday
afternoon as that cold front approaches, but mid-level ridging
remains strong along the coast. Mid and upper level energy rides
around the apex of the mid-level high north of the area, so
there is not much support for widespread convection with the
approach and passage of the cold front. Timing does not look
good, as the front does not pass through until late Sunday
night. Will carry chance PoPs to low-end likely PoPs for areas
north and west, but will only carry a chance for thunder.

&&

.LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/...
Cold front slowly works its way through the region Sunday
night. Not much in the way of mid-level troughiness. In fact,
the mid- level ridge remains over the area into Monday morning.
Although scattered showers are possible, not expecting much in
the way of convection, especially considering how warm and humid
it will be ahead of the front.

Cold front finally pushes offshore on Monday, but will become
nearly stationary south of the area and over the Mid-Atlantic
into the new week. Meanwhile, surface high pressure builds in
from the north. A fairly unsettled pattern sets up for most of
next week, as several weak waves of low pressure develop on that
stationary front. However, if the high is able to sag far
enough southward, that would help keep precip mainly focused on
southern areas. Either way, it is not looking like a washout for
most of next week, but chances are enough to keep at least
chance PoPs in the forecast for most of next week.

Highs will be around 15 degrees cooler Monday compared to
Sunday, and then temperatures will be on the cooler side of
normal for the rest of the week.

&&

.AVIATION /06Z FRIDAY THROUGH TUESDAY/...
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG,
KMIV, KACY and surrounding areas.

Early this morning...VFR with mostly high clouds, however some
patchy fog has tried to develop. High clouds streaming across
the region has allowed visibilities to recover though.
Southwest or south to southeast winds near 5 knots, becoming
light and variable to locally calm. Low confidence on
timing/restrictions with any fog.

Friday...Local fog possible early, otherwise VFR with some increase
in clouds. Showers and thunderstorms may move into portions of
the region between about 15-21z. Southerly winds increasing to
around 10 knots, with some gusts up to 20 knots especially at
ACY, MIV and ILG. Low confidence regarding shower/thunder timing
and coverage.

Outlook...

Friday night...VFR overall. Fog may develop at KACY and
possibly KMIV with sub-VFR VSBYs. S wind 5 to 10 kt. Moderate
confidence.

Saturday through Saturday night...VFR. Reduced VSBY in fog at
KACY and possibly KMIV. S to SW winds 5 to 10 kt. High
confidence.

Sunday through Sunday night...VFR on Sunday, and then scattered
SHRA/TSRA will result in sub-VFR conditions in the evening and
at night. SW winds 5 to 10 kt, becoming NW late Sunday night.
Moderate confidence.

Monday through Monday night...Mainly VFR. NW winds 5 to 10 kt.
Moderate confidence.

Tuesday...VFR. E winds 5 to 10 kt. Moderate confidence.

&&

.MARINE...
Southerly winds will prevail tonight around 10 knots. Areas of fog
are expected to develop overnight, some of which could be locally
dense reducing visibility to 1-3 NM. The winds will increase to
around 10-15 knots from the southeast during the daytime Friday.
Seas 2-3 feet. A few showers or thunderstorms are possible Friday
afternoon.

Outlook...

Friday night through Tuesday...Conditions overall will remain
below SCA criteria. S-SW winds generally 10 to 15 kt with 3 to 4
ft seas. The SW gradient will result in 15 to 20 kt winds
Sunday afternoon and evening, and seas may build close to 5 feet
as a cold front approaches. Winds shift to the NW behind the
departing front on Monday, and then an E wind develops for
Tuesday.

As a warm and humid airmass overspreads the colder waters
starting Friday night, reduced VSBYs in areas of fog are likely
through Sunday.

&&

.CLIMATE...
A hot and humid air mass is forecast to overspread the region
this weekend. The hottest day will be Saturday. Here is a list
of the high temperature records for Saturday and the record
high temperatures for the month of May.
