Area forecast discussion, Jul 10, 3:38 PM EDT, 4 hours 10 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/...

evening showers and thunderstorms. Southwest to south wind

&&

.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.
