Area Forecast Discussion
National Weather Service Mount Holly NJ

.WHAT HAS CHANGED...
Aviation section updated for 06Z TAFs.
The Small Craft Advisory in effect for Tuesday evening was
allowed to expire for the coastal waters from Sandy Hook to
Little Egg Inlet. A new Small Craft Advisory has been issued for
all of the nearshore Atlantic coastal waters from 12 PM
Wednesday to 12 AM Thursday.

.KEY MESSAGES...
1. There is another chance for isolated thunderstorms across
much of the area on Wednesday.
2. Dangerous heat and humidity will build over the Northeast
and Mid Atlantic Wednesday through Saturday. All time record
high temperatures could be challenged Thursday and Friday.
3. There is the potential for additional and more widespread
afternoon and evening thunderstorms starting on Friday and
lasting into the holiday weekend.
&&
.DISCUSSION...
KEY MESSAGE 1...There is another chance for isolated
thunderstorms across much of the area on Wednesday.
For Wednesday, instability is forecast to be high (potentially
3000 J/kg or greater) across the area, especially along and
northwest of I-95 by the afternoon hours. Due to the strong
subsidence and ridging building in from the west, there will
also be a lot of mid level dry air contributing to high DCAPE
(1000-1500 J/kg). Latest CAMs continue hinting at potential for
some convective initiation within this environment, despite the
strong subsidence. While coverage of any thunderstorms would be
relatively isolated, any storms that do form could be capable of
producing strong microbursts with damaging winds. SPC has
highlighted our northern half of our CWA in a MARGINAL (level 1
out of 5) risk for severe thunderstorms, with a SLIGHT (level 2
out of 5) in the far north.
KEY MESSAGE 2...Dangerous heat and humidity will build over the
Northeast and Mid Atlantic Wednesday through Saturday. All time
record high temperatures could be challenged Thursday and
Friday.
Strong mid-level ridging is developing across the Mississippi
Valley, Great Lakes, and Ohio Valleys early this week. Ridging
will then build eastward into the Northeast and Mid Atlantic by
Wednesday and persist into the holiday weekend. A west to
southwest flow on Wednesday will shift more west to northwest by
Friday. The ridge will finally start to break and retreat some
starting Saturday into Sunday.
High temperatures will climb into the mid and upper 90s on
Wednesday, and then from 100 to 105 degrees on Thursday and
Friday. With a south to southwest flow on Wednesday, dewpoints
are less likely to mix out significantly in the afternoon.
Resulting heat indices are forecast to range mainly from around
100-105 degrees. By Thursday and especially Friday, the shift to
a more west or northwest flow will allow for better mixing out
of dewpoints during the afternoon, and also a component of
downsloping (adiabatic warming) from the Appalachians. This will
support temperatures climbing above 100 degrees as dewpoints
mix out into the mid 60s during the afternoon hours. Resulting
forecast heat indices are mostly in the 105-110 degree range.
This is indeed the type of synoptic pattern that could challenge
all time record high temperatures in our region. See the
Climate section below for more information on record
temperatures.
Temperatures will abate somewhat on Saturday as the ridge
begins to break and retreat to the southwest. However, high
temperatures will still be in the mid 90s to near 100 degrees.
The prevailing flow direction will dictate how much mixing out
of dewpoints occur on Saturday. Currently, we have upper 60s to
near 70 degree dewpoints, which results in 100-105 degree heat
indices. Highs will remain in the low to mid 90s Sunday and
Monday as well, with heat indices still in the mid 90s to low
100s. So we certainly could see heat related impacts continuing
beyond Saturday despite a slight improvement in temperatures.
Given the increasing confidence in significant impacts from the
3 to 4 day excessive heat and humidity with heat indices
reaching into the 100-110 degree range each day, the Extreme
Heat Watch was previously upgraded to an Extreme Heat Warning
for all of southeastern Pennsylvania, northern Delaware, and
portions of New Jersey. This includes all areas where the
previous watch was effective beginning Wednesday afternoon
through Saturday. While heat indices may fall shy of warning
criteria by Saturday, impacts will likely be worsened by the
multiple days of heat and busy outdoor holiday festivities.
Elsewhere across far southern New Jersey, the New Jersey
barrier islands, and Delmarva, the Extreme Heat Watch remains in
effect beginning Thursday afternoon through Saturday. Within
the remaining watch area, heat indices up to 100 degrees are
possible on Wednesday, but the more notable heat won't begin
until Thursday, and the highest heat indices are more probable
on Friday.
The mid-level ridge will break and retrograde back towards the
south and west beginning Saturday, and a mid-level trough will
try to slide down into the Northeast. This pattern change will
begin to favor slightly cooler temperatures and a break in the
extreme heat by Sunday and Monday, as well as the potential for
showers and thunderstorms for the holiday weekend (see Key
Message 3 below).
KEY MESSAGE 3...There is the potential for additional and more
widespread afternoon and evening thunderstorms starting on
Friday and lasting into the holiday weekend.
The mid-level ridge looks to break down and retrograde back to
the south and west starting on Friday, and this will allow mid-
level troughiness to develop over the Northeast. With several
shortwaves riding over the top of the ridge and into the local
area, this may support more widespread afternoon and evening
showers and thunderstorms starting on Friday, but especially on
Saturday and Sunday. Currently, PoPs are around 10-20% on Friday
and 30-50% on Saturday and Sunday.
While details of this activity won't become clear until later
this week, it is important to point out that any holiday weekend
festivities could be impacted by thunderstorms (in addition to
the extreme heat). The environmental setup would be favorable
for strong to severe thunderstorms, if any storms do develop.
We'll continue to monitor this potential.

.AVIATION /06Z WEDNESDAY THROUGH SUNDAY/...
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG,
KILG, KMIV, KACY and surrounding areas.
Through 12Z...VFR. South to southwest winds remaining near 5-10
kts overnight. High confidence.
Wednesday...VFR. Very low risk of a shower or t-storm in the
afternoon. South to southwest winds remaining near 5-10 kts with
gusts upwards of 18 kt for KACY after 18Z. High confidence.
Wednesday night...VFR. Winds settling out of the southwest
around 5-10 kts. High confidence.
Outlook...
Thursday through Saturday...VFR. Low chance (20%) of a
thunderstorm Friday, better chance (30-40%) Saturday, otherwise
no significant weather.
&&
.MARINE...
The Small Craft Advisory has been allowed to expire for the
coastal waters from Sandy Hook to Little Egg Inlet. A new Small
Craft Advisory has been issued for all of the nearshore Atlantic
coastal waters from 12 PM Wednesday to 12 AM Thursday.
Winds tonight are out of the south-southwest at 10-15 kt with
gusts to 20 kt. Seas are 3-4 feet. Tomorrow, winds increase out
of the south-southwest at 15-20 kt with gusts of 25 kt. Seas
build to 4-6 feet. Through Wednesday night, winds and seas
gradually lessen.
Outlook...
Thursday through Friday...There is potential for marginal
advisory criteria to be met with winds increasing to near 20-25
kts with seas nearing 5 feet Thursday afternoon and evening,
mainly north of Atlantic City.
Rip Currents...
For Wednesday, breaking wave heights in the surf zone will be
increasing to around 3 to 4 feet with S/SW winds around 25 mph.
There will also be multiple swell groups and we'll still only be
2 days removed from the Full Moon. Given these factors, the
latest indications are that shore areas in Cape May and Atlantic
Counties in NJ will have a HIGH risk for the development of
dangerous rip currents. For our remaining NJ shore zones as well
as the Delaware Beaches, we'll continue with a MODERATE risk.
For Thursday, conditions look similar except both wind and wave
heights look to come down some and we'll also be another day
removed from Monday's Full Moon. For these reasons we're
forecasting a MODERATE risk for the development of dangerous rip
currents for our NJ shore zones and a LOW risk for the Delaware
beaches.
