Area Forecast Discussion
National Weather Service Mount Holly NJ
354 PM EDT Sun Jul 9 2023
.SYNOPSIS...
Low pressure was located in the Chesapeake Bay region this
afternoon. The low will drift northeastward, passing through our
region tonight. The system is forecast to lift slowly through
New England on Monday and Tuesday. High pressure is expected to
follow from the west and southwest for the mid week period.
Another frontal boundary may approach from the northwest late in
the week and over the weekend.
&&
.NEAR TERM /THROUGH MONDAY/...
A negative tilt mid level trough will lift northeastward over
our region this evening. A weak surface low is expected to
follow during the night. The robust lift with and ahead of the
short wave trough will continue to enhance the convection in our
region into this evening. Heavy rain and the threat for
localized damaging wind gusts will continue through that time.
The Flood Watches and Severe Thunderstorm Watches remain in
effect.
As the mid level trough begins to move away to our northeast
overnight, the showers and thunderstorms should taper to
scattered light showers. Lingering low clouds are likely.
Tonight's lows should favor the upper 60s and lower 70s with a
variable wind less than 10 MPH.
Another mid level trough is anticipated to pass eastward over
our region on Monday and Monday night. It should trigger a round
of scattered showers and thunderstorms for Monday, mainly in
the afternoon and evening. The activity should not be nearly as
widespread as today. Also, precipitable waters values are
forecast to drop below 2 inches, so the threat of localized
flooding will be greatly reduced. We are expecting a northwest
wind around 10 MPH on Monday with highs generally ranging from
the upper 70s to the middle 80s.
&&
.SHORT TERM /MONDAY NIGHT THROUGH WEDNESDAY/...
A strong mid level low is forecast to meander over lower Hudson
Bay in Canada and vicinity on Tuesday and Wednesday. We will
likely remain on the edge of its influence.
A continued westerly flow on Tuesday should continue to reduce
humidity levels somewhat. The trend is forecast to persist into
Wednesday. Both days are expected to be precipitation-free as
the surface low moves farther away from us and as high pressure
builds across our region.
Tuesday's maximum temperatures should be in the middle and
upper 80s with dew point readings dropping into the 60s. The air
mass will likely modify a bit for Wednesday, with afternoon
temperatures rising into the upper 80s and lower 90s at that
time.
&&
.LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/...
The mid level low is expected to remain over northern Ontario,
northeastern Manitoba and adjacent Hudson Bay from Wednesday
night through Friday and it may begin to drop southward over the
weekend. We should remain on the periphery of its influence
through the period.
Surface high pressure is forecast to move out to sea late in
the week. Humidity should be on the increase again late in the
week in the southerly flow on the back side of the high. Some
short wave energy traveling in the mid level flow along with
increasing instability could begin to trigger some mainly
afternoon and evening showers and thunderstorms each day from
Thursday through Sunday.
Temperatures will likely remain seasonable through the period.
&&
.AVIATION /20Z SUNDAY THROUGH FRIDAY/...
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG,
KILG, KMIV, KACY and surrounding areas.
Into this evening...Variable conditions with showers and
thunderstorms. The thunderstorms will be accompanied by MVFR/IFR
conditions and may bring locally strong wind gusts. Wind
generally southeast 5 to 10 MPH. Medium confidence.
Overnight...MVFR/IFR conditions with lingering showers.
Variable wind less than 10 knots. Medium confidence.
Monday...Mainly VFR. Scattered showers and thunderstorms could
briefly lower conditions to MVFR or IFR. Northwest wind 5 to 10
knots. Medium confidence.
Outlook...
Tuesday...Mainly VFR. Some early morning ceiling and visibility
restrictions are possible. Northwest to west wind around 10
knots. Medium to high confidence.
Wednesday...Mainly VFR. Some early morning ceiling and
visibility restrictions are possible. Southwest to south wind
around 10 knots. Medium to high confidence.
Thursday...Mainly VFR. Some early morning ceiling and
visibility restrictions are possible. A chance of afternoon and
evening showers and thunderstorms. Southwest to south wind 10 to
15 knots. Medium confidence.
Friday...Mainly VFR. Some early morning ceiling and visibility
restrictions are possible. A chance of afternoon and evening
showers and thunderstorms. West to southwest wind around 10
knots. Medium confidence.
&&
.MARINE...
Showers and strong thunderstorms are expected into this
evening. Southeast wind around 10 knots, becoming southwest
overnight, then westerly on Monday. Wave heights on our ocean
waters should be 2 to 3 feet, with waves on Delaware Bay at 2
feet or less.
Outlook...
Tuesday through Friday...No marine headlines are anticipated.
Rip currents...
There is a LOW risk for the development of dangerous rip
currents for the New Jersey and Delaware beaches through Monday.
A southeasterly wind around 10 MPH is expected into this
evening. Waves in the surf zone will remain around 2 feet.
Similar surf conditions are forecast for Monday, with a westerly
wind 5 to 10 MPH. A sea breeze may develop on Monday afternoon.
A medium period southeasterly swell is expected to continue
through this time.
&&
.HYDROLOGY...
There continues to be a significant threat for heavy rain this
afternoon and evening. Forecast rain amounts range from 0.75 to
2.25 inches across the region, but locally higher amounts are
likely. At this point, eastern Pennsylvania and northern New
Jersey remain the favored areas for the higher rainfall amounts.
The initial concern will be flash flooding, especially in areas
of poor drainage, including urban areas. Additionally, flooding
is possible on smaller creeks and streams.
Depending on where the band of highest rain amounts settles,
there is some potential for main stem river flooding with this
event. However, there is considerable uncertainty in where the
heaviest rain amounts will be and thus the ultimate impacts for
the main stem rivers.

Widespread heavy rainfall is expected across our forecast area
today. Below is a list of the daily precipitation records.
