Area forecast discussion, Sep 23, 6:18 AM EDT, 2 hours 54 minutes before
Area Forecast Discussion
National Weather Service Mount Holly NJ
618 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/...
Main changes to the forecast today are in regards to the timing of
the cold front impinging upon the region as it continues its quicker
trend, moving through the region a hour or two earlier.
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 dump several
inches of rain with localized amounts possibly exceeding three
inches. 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 to four inches still remaining 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 4 to 5000 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
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 /10Z THURSDAY THROUGH MONDAY/...
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG,
KILG, KMIV, KACY and surrounding areas.
Today...MVFR this morning will quickly degrade to IFR with rounds
showers and thunderstorms moving into the region. Best chances for
lightning will be after 15Z. Timing of the cold front has sped
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 confidence in trend, low 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 coastal waters through
the day. A Gale Warning remains in effect for the Delaware Bay from
6 am through 6 pm.
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.
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 today has already allowed for elevated water levels on the
eastern shore of Chesapeake Bay, which is expected to continue
through at least this morning. A coastal flood advisory remains in
effect for the eastern shore of Maryland through late this morning
as a result.
Water levels on the tidal Delaware River are also showing signs of
being elevated. At this time, confidence remains too low for the
issuance of an advisory, but we will continue to monitor the levels
closely through this morning. Rainfall today may exacerbate the
situation for this afternoons high tide, but confidence is not
particularly high, since the heaviest rainfall may occur after the
time of high tide.
