Area forecast discussion, Jun 8, 1:06 PM EDT, 1 hour 13 minutes before
Area Forecast Discussion
National Weather Service Mount Holly NJ
106 PM EDT Tue Jun 8 2021
.SYNOPSIS...
High pressure remains offshore through the week with a surface
trough in parts of our area through Wednesday. A cold front moves
into our area Wednesday night into Thursday, before sinking to the
south Thursday night and stalling there into the weekend. Some areas
of low pressure track along this boundary before it moves out to
sea. Another cold front approaches early next week.
&&
.NEAR TERM /THROUGH TONIGHT/...
As of 100 PM, convection ongoing across the Poconos into far
northwest New Jersey is producing torrential rainfall. This
activity appeared to develop from terrain influences, near a
surface trough and ahead of a weak shortwave. Farther south,
some isolated convection is developing west of the fall line. A
mesoanalysis indicated 2000-4000 J/kg of SBCAPE with MLCAPE up
to 2500 J/KG. Precipitable water is right about 2 inches in much
of our area and with warm cloud depths, very heavy rain/local
flash flooding is the main threat although cannot rule out a
local wet microburst associated with stronger pulse cores. Some
smaller hail is possible, however the airmass is very warm and
the freezing levels are just above 14000 feet (via both 12z
Dulles and Upton RAOBs). The forecast is in good shape overall.
Made some adjustments to the PoPs based on trends thus far.
With no change in the air mass, expect another hot and humid
afternoon. Temperatures should be slightly lower than Monday thanks
to increased cloud cover, however the dew points are in the 70s.
Thus, most of the coastal plain should see heat index values in the
mid to upper 90s prior to any convection. Consequently the Heat
Advisory continues for the urban corridor through early this evening.
For tonight, expect similar temperature conditions to what we
have seen the last several nights. The one possible exception is
that fog will be more likely anywhere that has a downpour
during the day. The mid level short wave trough doesn't get
fully east of our region until after 06Z, so there is a
potential for pulse showers and storms to continue through the
evening.
&&
.SHORT TERM /WEDNESDAY THROUGH THURSDAY NIGHT/...
Above normal temperatures and unsettled weather will continue
through the short term period.
On Wednesday, a lee-side/thermal trough will be in place across
the Mid Atlantic region, while a couple of short wave/vorticity
impulses are forecast to move across the area as well.
Meanwhile, PW values will remain around 1.75-2.00 inches and
CAPE values increase to 1000- 2000 J/kg. This will allow showers
and thunderstorms to develop across the area, with the
potential for heavy rainfall. Mid level flow is rather weak with
700-500 mb winds of 20-30 knots or less, so there is not much
shear forecast. Therefore, severe weather is not expected,
although any storms that do develop could have locally gust
winds and dangerous lightning.
On Wednesday night, a cold front is expected to sag southward
into the area from the north. This will allow additions showers
and isolated thunderstorms to develop across the area as the
short wave/vorticity impulses finally cross the area overnight
as well. Again, severe weather is not expected, but any showers
or thunderstorms could produce heavy rain.
By Thursday, the cold front is expected to stall across the Mid
Atlantic region, before an area of low pressure develops along
the front to or west overnight Thursday. With the front stalled
near the area, as instability develops during the day, there
will be a chance of showers and thunderstorms during the day. As
the low pressure develops along the front overnight and moves
eastward, along with a couple of short wave/vorticity impulses,
there will remain a chance of showers and thunderstorm overnight
as well. PW values will range from 1.75-2.25 inches, so the
heavy rain will continue to be a concern.
Given the low FFG values because of the all the recent
rainfall, flooding can not be ruled out, and much of SEPA, NJ,
and DelMarVa remain in a Marginal Risk for WPC's Excessive
Rainfall Outlook.
&&
.LONG TERM /FRIDAY THROUGH MONDAY/...
Unsettled weather is expected for much of the long term period,
with a return of below normal temperatures for the end of the
week through the weekend.
On Friday into Friday night, a couple of low pressure systems
will continue to move eastward along the frontal boundary that
will be stalled out near the Mid Atlantic region, which will
finally move the front to our south and offshore Friday night
into Saturday. However, before the front and low pressure
systems move away from the area, there will continue a chance of
showers and thunderstorms for much of the area Friday into
Friday night. PW values remain between 1.75-2.25 inches during
the day Friday, before dropping overnight Friday. Therefore,
there will continue to be a concern for heavy rain during the
day Friday, before rain chances diminish overnight.
A brief drying period could return on Saturday into Saturday
night as high pressure briefly builds across the Mid Atlantic
and Northeast region. However, this dry period may be brief as
another frontal boundary could affect the area around Sunday or
Monday of next week. There is some disagreement in the timing
and strength of the front, so we will stay close to NBM forecast
and keep a slight chance of showers in the forecast Sunday
through Monday.
&&
.AVIATION /17Z TUESDAY THROUGH SATURDAY/...
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG,
KILG, KMIV, KACY and surrounding areas.
This afternoon...VFR overall. Some showers and thunderstorms around,
which will result in local restrictions at times. Southwest to west-
southwest winds 5-10 knots, potentially more southerly at ILG and
ACY due to a sea/bay breeze. Low confidence on the timing details
and impacts of showers and storms at each terminal.
Tonight...Mostly VFR as any showers and thunderstorms dissipate in
the evening. Some fog however is possible overnight especially at
any terminals that had earlier downpours. Southwesterly winds around
5 knots, becoming light and variable. Low confidence on the extent
and timing of any fog.
Wednesday...Generally VFR. Showers and thunderstorms mainly in the
afternoon, resulting in local restrictions at times. West to
northwest winds 5-10 knots, except becoming southwest or south at
KACY. Moderate confidence.
Outlook...
Wednesday night...Generally VFR. Showers and thunderstorms
diminish. West to northwest winds 5-10 knots from around I-95
corridor northward, west to southwest south of I-95 corridor.
Wind shift to north to northeast overnight. Moderate confidence.
Thursday...Mostly VFR conditions expected. Showers and
thunderstorms likely which could temporarily lead to lower
conditions. East to northeast winds 5-10 knots. Moderate
confidence.
Thursday night...Conditions lower to MVFR then IFR overnight.
Showers and thunderstorms likely. East to northeast winds 5-10
knots. Moderate confidence.
Friday-Friday night...IFR conditions during the day, improving
to MVFR overnight. Showers likely, especially during the day.
East to northeast winds 5-10 knots.
Saturday...Conditions improve to VFR, with some MVFR ceilings
possible. A slight chance of showers. Northeast winds 5-10
knots, shifting to east to southeast later in the day.
&&
.MARINE...
Winds and seas should stay below Small Craft Advisory
Conditions today and tonight. However, higher winds and seas
will be possible in the vicinity of thunderstorms this afternoon
and evening.
Patchy fog is possible very late tonight.
Outlook...
Wednesday-Thursday night...Conditions expected to remain below
advisory levels. A chance of showers and thunderstorms which
could lead to locally higher winds and waves.
Friday-Saturday...Winds and waves could reach Small Craft
Advisory levels for some areas.
Rip Currents...
A LOW risk for the development of dangerous rip currents
continues today and Wednesday for the New Jersey and Delaware
beaches, with just modest southerly flow and waves around 2 feet
in the surf zone.
