Area Forecast Discussion
National Weather Service Mount Holly NJ
332 AM EDT Sat Aug 28 2021
.SYNOPSIS...
A weak cold front will slide into the region tonight before
becoming stationary over or just south by tomorrow. The front
may lift north as a warm front Sunday night. Another cold front
could move through the region Monday into Monday night. The
remnant low of Hurricane Ida may progress along that frontal
boundary during the middle to later half of the week.
&&
.NEAR TERM /THROUGH TONIGHT/...
Scattered showers continue across parts of the areas as the
cold front currently running across Pennsylvania and northern
New Jersey continues to sag southward this morning. When rain
stops, patchy fog will develop and continue through the morning
hours.
There is some strong shortwave energy over southern New Jersey,
and this will interact with the front to allow for a weak wave
of low pressure to develop in that area. Cooler air sags into
northern New Jersey and the southern Poconos, so although
scattered showers and thunderstorms are possible here, PoPs will
be fairly low, and not expecting heavy rain. Onshore flow south
of the front will allow for moisture to increase, and PWATs
will be in excess of 2.5 inches across southern New Jersey.
Instability will be high here, as well, with SB CAPE values
around 2000 J/kg.
The focus will be on southern New Jersey, and that is where the
heavy rain will be focused. Will go ahead and cancel the Flash
Flood Watch for all of southeast Pennsylvania, northern
Delaware, and most of New Jersey, and will keep it up for mainly
along the coast.
Really not a great day, as onshore flow will also allow for
status to develop. So not expecting much in the way of sunshine,
except for maybe portions of Delmarva, where it remains south
of the cold front, and thus, it will stay quite warm and humid.
A wide range of high temperatures on tap for today, with highs
in the low to mid 70s in the southern Poconos and northern New
Jersey, and generally in the mid to upper 70s to around 80 in
southeast Pennsylvania and southern New Jersey. Southern
Delmarva will be in the mid to upper 80s.
Showers taper off tonight, and with abundant low level moisture
over the area, patchy fog is possible once again. Lows tonight
generally in the 60s to low 70s.
&&
.SHORT TERM /SUNDAY THROUGH MONDAY/...
Depending on how close the front stalls to our region, some
chances for showers and thunderstorms could continue Sunday.
Even with the front south of our region, overnight fog will
continue to be possible as dew points should remain in the 60s
for much of the region.
Chances for showers and thunderstorms start to increase
considerably on Monday as the next cold front approaches the
region.
With the front south of our region on Sunday, highs should once
again be in the 70s and 80s. By Monday, assuming that the next
cold front won't arrive until later in the day, highs near 90
will once again be possible especially across the coastal
plains.
&&
.LONG TERM /MONDAY NIGHT THROUGH FRIDAY/...
Unsettled conditions on tap for most of the week. The big
question is how the remnant low of Hurricane Ida interacts with
the front and the ultimate impacts for our region. If the front
is still near our region, tropical moisture associated with the
remnant could lift towards the area and may bring another round
of showers and thunderstorms with heavy rain to the region
sometime late Tuesday through Wednesday. It depends on its
track, and it is quite uncertain right now, as it could pass
well south of the region.
Another, possibly stronger, cold front may pass through the
region towards the end of next week with a cooler and dryer
airmass.

in effect for ANZ450-451 as winds will gust to 25 kt and seas
will build to 4-6 feet. For the rest of the waters, wind gusts
will be up to 20 kt, and seas will be 2-4 feet.
Outlook...
Sunday through Wednesday...Once seas subside below 5 ft either
late Saturday night or Sunday morning, winds and seas should
stay below SCA criteria for the remainder of the period.
Several wind shifts likely. Showers and thunderstorms likely
at times.
Rip Currents...
There is a LOW risk for the development of dangerous and life
threatening rip currents for the NJ and DE beaches. However,
conditions may become stronger at Monmouth and Ocean counties
depending on how strong winds get,
The LOW risk continues into Sunday.
