Area Forecast Discussion
National Weather Service Mount Holly NJ
1236 PM EDT Fri Jul 16 2021
.SYNOPSIS...
High pressure located over the western North Atlantic will lose
its influence over our weather gradually through Saturday. A
cold front approaching from the northwest is forecast to arrive
on Sunday. The boundary is expected to stall and slowly
dissipate in or near our region early new week. Another cold
front is anticipated to reach eastern Pennsylvania, New Jersey,
eastern Maryland and Delaware around Wednesday night.
&&
.NEAR TERM /THROUGH TONIGHT/...
West-southwesterly flow will prevail this afternoon with a
stalled or very slowly moving frontal boundary positioned across
the southern Great Lakes region to our northwest. With heights
rising a bit aloft and southwesterly warm air advection
continuing, expecting widespread high temperatures in the low to
mid 90s along with dewpoints in the low 70s. Resulting Heat
Indicies are forecast to rise into the low 100s mainly along and
south/east of the urban corridor. The Heat Advisory thus
continues for portions of the area. Winds sill be from the
southwest around 5-10 mph.
While there won't be a whole lot of mid-level support for
convection, instability will rise to near 2000 J/kg near and
north/west of I-95. Shear will be weak, only around 15-20 kts at
best where the instability and forcing will be the greatest.
Thus, expect some isolated showers and thunderstorms to develop,
mainly north/west of I-95. Wouldn't be surprised to see a few
showers or storms fire up along the sea breeze either. Severe
potential appears low given weak forcing, weak shear, and poor
mid-level lapse rates (~5 C/km). Nevertheless, SPC has
highlighted areas along and north of I-78 in a Marginal Risk for
isolated damaging wind gusts with any stronger cores that are
able to develop.
Expect a muggy night with lows in the low to mid 70s and light
to calm winds. A weak mid-level wave may allow for some isolated
convection to continue into the overnight period, mainly near
and north of the I-78 corridor.
&&
.SHORT TERM /SATURDAY THROUGH SATURDAY NIGHT/...
On Saturday, a mid-level shortwave trough will approach from
the Ohio Valley. The trend with this feature appears to be
slower, which makes sense given that some guidance attempts to
close off a weak mid- level low somewhere across the southern
Great Lakes region. I suspect this will result in convection not
developing until late in the afternoon or evening and
potentially lingering past the midnight hour. This will also be
dependent on the timing and placement of a slowly approaching
frontal boundary from the north, which has also trended a bit
slower. Nevertheless, the forcing is forecast to arrive at some
point late in the day with instability building once again to
near or over 2000 J/kg. The approaching shortwave will also
result in stronger mid-level flow and thus greater forcing than
Friday with effective shear increasing to near 30 kts. This
should result in at least an isolated severe threat, but the
mid-level lapse rates remain poor which should preclude a more
widespread damaging wind or large hail threat. SPC has
highlighted the majority of the forecast area in a Marginal Risk
for damaging winds with any stronger or more organized
convection that develops.
The bigger story for Saturday will be the potential for locally
heavy rainfall with the storms developing into the afternoon
and evening. As with any convectively driven heavy rainfall and
flash flooding potential, confidence is low on exactly where the
heaviest rainfall will occur at this time. In addition to the
modest instability developing into the afternoon, Precipitable
Water values will rise to near or over 2". Unlike the flash
flood environment we had this past Monday, the convection will
be moving, but could begin to train over the same area with any
boundary interactions. WPC continues to highlight areas along
and north/west of I-95 in a Slight Risk for excessive rainfall,
and this may need to be upgraded to a Moderate Risk in a future
update as confidence increases on the placement of heaviest
rainfall. A Flash Flood Watch may thus also be needed for this
threat as well if confidence increases enough that portions of
the area may receive flash flooding on Saturday.
Long story short, widespread convection is expected in the
forecast area, especially along and north/west of I-95.
Temperatures will once again rise into the low 90s with low 70s
dewpoints. The Heat Advisory remains in effect for Saturday with
maximum Heat Indicies rising to near 100 degrees near and south
of Philly, and values possibly nearing 105 degrees across
portions of Delmarva.
The showers and thunderstorms should linger for some time into
the overnight period, but should generally wane in intensity and
coverage after midnight. Expect another muggy night with lows
in the low 70s.
&&
.LONG TERM /SUNDAY THROUGH THURSDAY/...
Sunday morning a cold front will remain near the CWA with
another impulse approaching from the west. There are some
discrepancies on where exactly the front will be Sunday, with
the GFS being the most progressive and having the cold front
clear the coast Sunday morning. The ECMWF, CMC, and NAM all have
the front hung up somewhere near the Delaware River Sunday and
this overall seems to make sense. The upper level forcing
responsible for pushing the cold front through NJ remains mainly
back to our west at the time. Ahead of the frontal zone, PWATs
remain around 2" which is at or slightly above the 90th
percentile for this time of year. Convective initiation will
also be aided by an approaching jet streak across central PA.
Given the above, another round of locally heavy rainfall will be
possible Sunday.
Monday, guidance continues to struggle with the evolution of a
shortwave diving southeast out of the Great Lakes region. The
ECMWF closes the wave off into an area of low pressure, while
the GFS keeps the wave open. Either way, this also favor a
slower progression east of the cold front. The CMC actually has
another round of convection Monday in association with the
stalled boundary near the PA/ NJ border. The ECMWF stalls the
boundary more towards the NJ coastline. This solution makes
sense, as convective outflow will likely help to push the front
towards the coast, but not be strong enough for the front to
completely clear the DE and NJ coastlines.
Tuesday into Thursday, a longwave trough axis will center
across the east coast of the United States with a mid-level
ridge building over the Mountain West. The overall consensus is
for several more rounds of embedded shortwaves to traverse the
region, keeping the chance of precipitation in for the remainder
of the work week. There is some disagreement on the amplitude
of the wave, but as of now, seasonable temperatures and humidity
are forecast.
