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.

6 thunderstorm wind, 1 tornado, 1 funnel cloud. Local standard time, as filed.
Report of large tree limbs down on Pearsons Corner Road in Dover. Time estimated via radar.
Emergency Manager Coordinator relays report of a roof blown off a house on Choppin Drive in Middletown. Time estimated via radar.
An EF-1 tornado began about 4 miles northeast of Middletown, DE just north of DE Route 896 (Boyds Corner Road) in a field just west of North Bayberry Parkway. Prior to the tornado development, some notable rear flank downdraft straight line wind damage occurred in the Bayberry South neighborhood. Several homes along South Bayberry Parkway, Puccini Lane, Chopin Drive, and Ravel Lane sustained primarily minor cosmetic damage to soffit and gutters. Some singles and siding were blown off as well. One home on Chopin Drive had a very small section of roof blown off. The rear flank downdraft winds continued northeast crossing DE Route 896 where a few small signs were blown over, including damage to the Bayberry North neighborhood sign. A single family house and detached garage near the intersection of North Bayberry Parkway and DE Route 896 sustained some cosmetic damage. Additionally, several trees sustained varying degrees of damage on and immediately surrounding this property. No additional straight line winds were found beyond this property. The tornadic circulation began about 200 yards northwest of the aforementioned property where several small to medium sized softwood trees were damaged or uprooted, falling in a convergent pattern, along North Bayberry Parkway. The tornado continued northeast where it caused some minor damage to a small park playground and pavilion. The tornado moved northeast through a field and across a pond, then impacted one home along Plato Place. This home sustained some cosmetic damage and a fence was blown down. The tornado then continued into a tree line where some trees were uprooted, then emerging into a residential area along Milford Drive. This is where the tornadic circulation reached its maximum width of about 200 yards. Additional trees were uprooted or snapped along the western loop of Milford Drive and a few homes sustained some minor cosmetic damage. The tornado continued northeast toward the western loop of Milford Drive where it strengthened. A tree line of cedar trees had most trees uprooted. One homes detached garage had a garage door blown inward and an exterior wall pushed outward, but not completely collapsed. The home itself had several singles and shutters blown off. Another home had a back deck porch roof completely blown off and destroyed. A hot tub was blown off of its supports and flipped over and much of the patio furniture was blown dozens of yards away. Another detached garage at another residence sustained some minor cosmetic damage as well. The tornado continued along Ethel Court where primarily tree damage occurred, including another row of cedar trees that were blown down. The tornado continued northeast along Bullen Drive, turning slightly left as the circulation began to occlude. Numerous small trees sustained varying degrees of damage just north of the Asbury Loop intersection. Several residences along Bullen Drive were impacted from near the intersections of South Red Fox Circle and North Red Fox Circle, particularly on the eastern side where the most significant damage was noted. Numerous trees were snapped or uprooted in this area. One home had a large chimney blown off, landing in the backyard. Another home had a large section of attic wall blown off along with roofing material blown off. The most significant damage from the tornado occurred to a home where the entire attached garage roof was blown off into the front yard. This home also had an upstairs window blown out and the northeast facing upstairs exterior wall was pushed outward, but not completely collapsed. The home northeast had nearly an entire side of the house stripped of siding. A home across the street had a portion of its porch roof lifted and another had 3 windows blown out along with other cosmetic damage. The tornado then moved north-northeast crossing Angelo Court where two homes sustained minor cosmetic damage and had a few small trees uprooted. The tornado then dissipated as it reached Hyatts Corner Road. No known injuries or fatalities occurred from this tornado. The survey team found additional wind damage farther northeast of where the tornadic circulation dissipated. A semi-truck was blown over on DE Route 1 southbound just downstream. Some corn was blown down in a field east of US Route 13, but there was no supporting evidence of a tornadic circulation in this area. Additional sporadic tree damage and some minor cosmetic damage to homes was found in residential areas along and off of Port Penn Road, including along Sugar Pine Drive and Dutch Neck Road. Some additional blown down corn was found in some fields farther along Dutch Neck Road. This damage was determined to be the result of straight line winds.
