What forecasters said that day

The local office's own words before this severe thunderstorm warning 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 severe thunderstorm warning went out at Jul 10, 3:38 PM EDT, 3 hours 32 minutes earlier.

Area forecast discussion, Jul 10, 3:38 PM EDT, 3 hours 32 minutes before
Area Forecast Discussion
National Weather Service Mount Holly NJ
338 PM EDT Mon Jul 10 2023

.SYNOPSIS...
Low pressure will lift northward across New England tonight.
High pressure located in the middle and lower Mississippi River
Valley, and in the Ohio River Valley this afternoon will build
to the east. The center of the high is forecast to pass off the
Middle Atlantic and Southeast coasts on Wednesday. A frontal
boundary is expected to approach slowly from the northwest late
in the week. The front may arrive in our region on Saturday
night or Sunday.

&&

.NEAR TERM /THROUGH TUESDAY/...
High pressure across the Ohio Valley expands to the east
tonight and Tuesday as the flow aloft becomes more zonal. This
will bring drier air to the area tonight and it will remain for
Tuesday. Skies will become mostly clear overnight and it'll
remain sunny for Tuesday. Look for lows tonight range from the
upper 50s/low 60s for the N/W areas including the Lehigh Valley
and north NJ while Delmarva and metro Philadelphia have lows in
the mid/upper 60s. For Tuesday, highs will climb above normal
with mostly mid/upper 80s expected. Humidity levels will be in
the comfortable range however.

&&

.SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY/...
A mid level low is forecast to meander over lower Hudson Bay
and northeastern Manitoba from Tuesday night through Thursday.
We will remain on the outer edge of its influence. Surface high
pressure is forecast to be located along the central and
southern Appalachians on Tuesday night. The air mass will
continue to modify as it builds eastward. The center of the high
is forecast to pass off the Middle Atlantic and Southeast
coasts on Wednesday.

Humidity levels should remain relatively low on Wednesday, with
dew point readings mainly in the 60s. As the return southerly
flow on the back side of the high becomes increasingly
established on Thursday, dew point readings should climb back
into the lower 70s. Most of southeastern Pennsylvania, New
Jersey, Delaware and eastern Maryland are expected to reach the
lower 90s on both Wednesday afternoon and Thursday afternoon.
Heat index values are anticipated to be close to the actual air
temperatures on Wednesday. However, the increasing humidity will
likely result in maximum heat index values in the middle and
upper 90s on Thursday.

Nighttime temperatures are forecast to be seasonable. They will
likely range from the lower 60s to around 70 degrees on Tuesday
night, and from the lower 60s to the middle 70s on Wednesday
night.

The relatively dry core of the air mass is expected to preclude
the development of any precipitation for our region from
Tuesday night into Wednesday night. The increasing humidity and
a mid level short wave trough approaching from the west may
bring scattered showers and thunderstorms for Thursday
afternoon. A developing southwesterly low level jet around 30
knots may provide enough shear to result in some organized
convection at that time. Also, precipitable water values are
forecast to rise to around 2 inches, possibly resulting in
localized downpours.

&&

.LONG TERM /THURSDAY NIGHT THROUGH MONDAY/...
The slow moving mid level low is expected to slide from
northeastern Manitoba on Friday to central Ontario on Monday.
Short wave energy traveling in the mid level flow and the
increased humidity levels should enhance our potential for
scattered mainly afternoon and evening showers and
thunderstorms, each day from Friday through Monday. It appears
as though a weak frontal boundary may arrive on either Saturday
night or Sunday with a secondary front possible around Monday.

Temperatures will likely remain seasonable through the period
with highs mostly in the upper 80s and lower 90s, and lows
mainly in the upper 60s and lower 70s.

&&

.AVIATION /20Z MONDAY THROUGH SATURDAY/...
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG,
KILG, KMIV, KACY and surrounding areas.

Rest of today... VFR mostly. Decreasing amounts of low clouds.
Northwest winds 10 to 12 knots with gusts to 18/20 kts possible.
High confid.

Tonight... VFR. Mostly SKC. Light West or Northwest winds. High
confid.

Tuesday... VFR expected. Mostly clear skies. West winds 5 to 10
knots. High confid.

Outlook...

Wednesday...Mainly VFR. Southwest to south wind increasing to
around 10 knots. 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
increasing to 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. Southwest wind around 10 knots.
Medium confidence.

Saturday...Mainly VFR. Some early morning ceiling and
visibility restrictions are possible. A chance of afternoon and
evening showers and thunderstorms. Southwest to south wind
around 10 knots. Medium confidence.

&&

.MARINE...
Low pressure to the north will continue to move away tonight. A
west to northwest flow behind it will continue tonight and then
winds will turn more west on Tuesday. Wind speeds will mostly
be 10 to 15 kts into the evening before decreasing after
midnight. A couple gusts to 20 kts are possible across the
Northern NJ waters. Fair weather predicted tonight and Tuesday.

Outlook...

Wednesday through Saturday...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 into this
evening. Waves in the surf zone will remain around 2 feet.
Westerly winds 5 to 10 mph, except where any weak local sea
breeze develops. A medium period southeasterly swell is expected
to continue through this time.

For Tuesday there is a LOW risk of rip currents as well.
Conditions will remain very similar to today, with a minimal SE
swell, and winds tending W to SW around 5 to 10 mph.

0449 PM     Tornado          4 NE Middletown         39.50N 75.67W
07/09/2023                   New Castle         DE   NWS Storm Survey

            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. The National Weather Service
            would like to thank New Castle County
            Emergency Management and Mr. Lou Ruh for
            providing assistance with this survey.
