Area Forecast Discussion
National Weather Service Mount Holly NJ
1044 AM EDT Thu Sep 23 2021
.SYNOPSIS...
A cold front will move into the region today and pushing to the
east through tonight. High pressure will build into the Mid-
Atlantic from the southwest for Friday and Saturday. A weak cold
front will cross the region later Saturday followed by a return
to high pressure for Sunday through Tuesday. Yet another cold
front will approach the region later Tuesday.
&&
.NEAR TERM /THROUGH TONIGHT/...
Mid-Morning Update...
Very little change to the forecast this morning. Made some
adjustments to hourly PoPs based on radar trends, but overall
thinking remains the same. While the front approached a little
faster than expected overnight, it is now slowing down as it
moves into the area, and it will take most of the day for
showers and thunderstorms to move through. Eastern areas will
even continue to see breaks of sun for another couple hours
before rain gradually overspreads. We have already seen some
impressive rainfall amounts over eastern Maryland as cells train
from south to north. As the front crawls eastward, the risk for
training cells and heavy rain will gradually shift east as
well. The potential remains for at least localized flash
flooding. Am not overly concerned about the severe threat due to
limited instability, but with a strong LLJ there remains a
threat for a convectively enhanced damaging wind gust, and given
strong low level SRH (shown nicely in 12z RAOBs from OKX and
WAL), still cannot entirely rule out an isolated tornado.
Previous discussion follows...
A few light showers have worked their way across the Delaware
Valley this morning, but a stronger line of showers and possibly
some embedded thunder is forming across the western Chesapeake
Bay and is expected to push eastward to the Eastern Shore later
this morning. Further to our west, a deeply occluded upper-
level low is centered over the Ohio Valley, with a rigorous dry
slot working northward between it and the associated
cold/occluded front to its east.
One concern today with this front continues to be the flash
flooding threat with the area of greatest concern being the
Lehigh Valley and Poconos where orographic enhancement is likely
to enhance heavy rainfall potential. A swath of PWAT values
exceeding two inches just to our west continues to move towards
our region this morning. A big factor at play will be exactly
how quickly the front moves east with a rather abrupt end to the
rainfall as the dry slot moves into the region from west to
east. Latest guidance has suggested this may push eastward a
little more quickly, which has resulted in a slight decrease in
rainfall totals, though the risk for localized amounts exceeding
three inches still remains across eastern Pennsylvania. A Flash
Flood Watch remains in effect for much of the region along and
west of the I-95 corridor.
Another item of concern is the severe threat. The impressive
synoptic-level winds with the system will likely be mixed down
to the surface with some of the stronger showers and
thunderstorms with 40 to 50-knot winds only a few thousand feet
above the surface with a very rigorous low level jet shooting
from south to north ahead of this front. With the more
southeasterly flow at the surface and southerly to south-
southwesterly winds in this jet, the threat for isolated
tornadoes continues to remain. Any updrafts that can tap into
this pre-existing low-level wind shear will easily be able to
rotate. 0-3km SRH values from 200 to 300 m2/s2 largely support
this threat. The more surface heating and sunshine we see early
today, the greater the threat is likely to be. With forecast ML
CAPEs around 1000 J/kg across the I-95 corridor, this should be
enough to get a few stronger cells going.
Otherwise, highs today will be seasonably warm in the upper 70s
to near 80 and lows dropping into the upper 50s tonight behind
the front. Warmer values near the coast with the front not
clearing the region as fast. Highs tomorrow will be a little
cooler in the low 70s.
&&
.SHORT TERM /FRIDAY THROUGH SATURDAY NIGHT/...
The cold front pulls off to the east on Friday, allowing for
dry air to quickly push into our forecast area. With clearing
skies and plenty of sunshine, it will feel quite fall-like on
Friday as highs only rise into the 60s to lower 70s across the
region. With dew points in the 50s, it will feel much more
comfortable than it has in recent days.
With the skies remaining clear into Friday night and winds
dropping off, we should radiate fairly well. Overnight lows will
drop into the mid 40s to lower 50s across the area.
Saturday will feature high pressure building cresting overhead.
A few clouds around the region during the day but otherwise
mostly sunny skies are expected. Highs will be similar to
Friday, through with some slight warming aloft in the southwest
flow it should be a couple of degrees warmer. A weak cold front
will approach from the west as a deep upper trough pushes
towards the area, moving through later Saturday night. While
there will be quite a bit of energy available aloft, the front
itself is moisture starved and we are not expecting any showers
to develop as it moves through and makes its way offshore
Saturday night.
&&
.LONG TERM /SUNDAY THROUGH WEDNESDAY/...
Surface high pressure will build across the region for Sunday
through Tuesday, keeping the region dry. Aloft, a trough will
dig down and cross the region Sunday into Monday. While there is
no moisture associated with this trough passage, there should
be some cooler temperatures which will keep the highs on Sunday
slightly below normal and in the 60s to lower 70s through much
of the region. As we go through Monday and Tuesday, the air mass
will moderate and warm a few degrees each day.
A weak cold front will approach the region on Tuesday, passing
through Tuesday night. Some rain showers may accompany the front
and we can't rule out a few rumbles of thunder.
Ridging aloft along with surface high pressure will once again
move over the region for midweek with warmer and drier
conditions expected.
&&
.AVIATION /15Z THURSDAY THROUGH MONDAY/...
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG,
KILG, KMIV, KACY and surrounding areas.
Today... A mix of MVFR with some remaining pockets of VFR
should continue through the morning as a frontal system and
associated rainfall slowly approaches. All terminals should drop
to MVFR by this afternoon, with widespread MVFR and localized
IFR through this evening with rounds of showers and
thunderstorms, heavy at times. Timing of the cold front has sped
up slightly, thus southeasterly winds from 15 to 20 knots
through 20Z with gusts up to 30 knots will begin to quickly
shift westerly as the front passes through the region. The front
looks to pass slowly across the region from 20Z at RDG to 22Z
at the Philly terminals to 06Z at ACY. Moderate to high
confidence in overall trend, lower confidence in exact timing of
wind shift and categorical shifts.
Tonight...A gradual improvement from lingering MVFR to VFR
through the early morning. West-southwesterly winds shifting to
west- northwest from 5 to 10 knots. Moderate confidence.
Friday...VFR with westerly winds from 5 to 10 knots. A few
showers may linger along the coast in the morning hours bringing
probable MVFR restrictions through 16Z. High confidence.
Outlook...
Friday night through Sunday...Mainly VFR expected. West to
northwest winds around 10 knots, increasing to 10 to 15 knots on
Sunday. High confidence.
Monday...Mainly VFR expected. West to southwest wind around 10
to 15 knots. High confidence.
&&
.MARINE...
Today...Southeasterly winds from 15 to 20 knots with gusts to
30 knots. Seas building to 4 to 7 feet with a few 8-foot
breaking waves possible. An SCA remains in effect for the
Atlantic coastal waters through the day. A Gale Warning remains
in effect for the Delaware Bay through 6 pm as the funneling of
southeasterly flow up the Bay allows for some gusts near to
above 35 kt, the likes of which have already been observed.
Tonight...Winds turning westerly and dropping to 10 to 15 knots
but seas will linger from 4 to 6 feet through the night, thus
the SCA remains in effect through the overnight for the Atlantic
coastal waters.
Friday...Northwesterly winds from 5 to 10 knots with gusts to
15 knots. Seas remaining elevated through 4 pm from 3 to 5 feet.
Outlook...
Friday night through Monday...No marine headlines are
anticipated. Westerly winds around 10 to 15 knots, with some
gusts around 20 knots on Sunday. Seas generally around 2 to 4
feet.
Rip currents...
We have forecast a HIGH risk of dangerous rip currents for
today for both NJ and DE beaches, as winds become a little
stronger with an increasing swell.
A HIGH risk will continue for the NJ beaches on Friday with a
MODERATE risk expected at the DE beaches.
A Rip Current Statement is in effect for the DE beaches through
tonight and for the NJ beaches through Friday evening.
&&
.TIDES/COASTAL FLOODING...
Strong southerly flow in advance of the system moving through
the region resulted in elevated water levels on the eastern
shore of Chesapeake Bay, where some minor tidal flooding has
occurred. A Coastal Flood Advisory remains in effect for Kent
County until noon.
Water levels on the far upper Delaware Bay and on the tidal
Delaware River are also elevated due to the strong southeast
wind. We have issued a Coastal Flood Advisory for those areas
for this afternoon.
