Area Forecast Discussion
National Weather Service Mount Holly NJ
1025 AM EDT Tue Jul 4 2023

.SYNOPSIS...
A cold front over the area will slide towards the Mid-Atlantic
tonight through Wednesday before returning north as a warm front
on Thursday. A cold front approaches on Friday and passes
through the region Friday night. A series of disturbances will
then pass through the region over the weekend and into the start
of the new week.

&&

.NEAR TERM /THROUGH TONIGHT/...
Clouds will remain rather widespread today, but some breaks have
started to develop and ceilings are slowly lifting. A slow
moving short wave is already, as of 10 AM, starting to set off
more showers and scattered tstms for ern PA, NJ and perhaps
DE/ne MD too. Will keep the broadbrush pops for now in the high
chc/low likely range favoring the North part of the CWA. The
wind fields will decrease markedly today, so a rather limited
chance for any severe storms, but the threat for heavy rains is
again present for later today. Will be considering a flood
watch, but given that areas which are most likely to see rain
today mostly missed out yesterday, am currently leaning a bit
against it.

Humidity levels will remain high today but the clouds will
probably hold temperatures a few degrees lower than Monday.
Mostly mid/upper 80s are expected. Winds will be light favoring
W/NW.

Tonight, after the weak short wave passes offshore. Improving
conditions are expected. Skies will become partly cloudy and
some fog will probably develop where todays rains occur. Lows
will hold in the mid/upper 60s for the Lehigh Valley, southern
Poconos and north NJ. Lows will be in the low 70s elsewhere.

&&

.SHORT TERM /WEDNESDAY THROUGH THURSDAY NIGHT/...
Weak surface high pressure will be centered south and west of
the area on Wednesday. Cold front will be south of Delmarva,
over the Mid-Atlantic. A very warm and humid airmass will be
over the area with highs in the upper 80s to around 90 with
surface dew points in the upper 60s to around 70 on Wednesday.
Some mid-level shortwave energy will pass through the region,
and this may be enough to spark off some isolated to scattered
showers and thunderstorms in the afternoon.

Warm and humid Wednesday night with lows in the upper 60s to
low 70s. Patchy fog possible.

That cold front over the Mid-Atlantic returns north as a warm
front on Thursday. Winds take on a more southerly flow, and
surface dew points will be a few degrees higher than Wednesday,
generally in the upper 60s to low 70s. Highs on Thursday will
also be a couple of degrees higher, mainly in the upper 80s to
low 90s. Max heat index values on both Wednesday and Thursday
will be in the low to mid 90s in southeast Pennsylvania and New
Jersey, and in the mid and upper 90s in Delmarva.

Again, some mid-level shortwave energy passes through the
region on Thursday with isolated to scattered showers and
thunderstorms in the afternoon. Another warm and humid night on
tap Thursday night along with patchy fog and lows in the upper
60s to low 70s.

&&

.LONG TERM /FRIDAY THROUGH MONDAY/...
A tropical airmass will be in place over the Northeast and
Delmarva for the Long Term period with surface dew points
generally in the 60s to low 70s. Meanwhile, a closed upper low
will be parked over Hudson Bay. Several troughs and strong
shortwaves will spin off this low, sparking off thunderstorm
chances over the area.

The first trough passes north of New York State on Friday, but
it will drag a strong cold front through the Northeast Friday
afternoon and evening. Showers become likely with a chance for
thunderstorms in the far western zones by Friday afternoon, with
chances elsewhere. Heat and humidity will be in place for
convection, but there may not be enough upper level energy nor
enough shear for widespread convection.

Some strong shortwave energy will pass through the region over
the weekend, potentially touching off afternoon and evening
showers and thunderstorms. Will follow NBM and keep chance PoPs.

A stronger cold front may approach for Monday with some more
widespread showers and thunderstorms. For now, will keep chance
PoPs.

After high temperatures approaching 90 in some spots on Friday,
highs will generally be in the low to mid 80s over the weekend
and into the start of the new week.

&&

Outlook...

Wednesday through Saturday...Overall, a prolonged period of
sub- SCA conditions. VSBY restrictions in afternoon and evening
showers and thunderstorms possible each day, but best chances
are Friday and Saturday.

Rip currents...

For Tuesday, there is a LOW risk for the development of
dangerous rip currents for the New Jersey and Delaware beaches.
The wind should be from a southerly direction around 10 mph.
Breaking waves are forecast to be around 2 feet with a medium
period south to southeast swell. The risk for the development of
dangerous rip currents is expected to stay LOW for Wednesday.

&&

.TIDES/COASTAL FLOODING...
The evening high tide cycles will be elevated along the ocean
and into Delaware Bay through the middle of the week. Tide
levels will generally be +0.6 to +1.0 feet above normal, and
minor coastal flooding thresholds will be touched. This will
result in spotty minor tidal flooding around the evening high
tide cycles.
