Area Forecast Discussion
National Weather Service New York NY
345 PM EDT Tue Jul 6 2021
.SYNOPSIS...
A surface trough lingers over the region as high pressure
remains over the western Atlantic through Wednesday. A cold
front nears the region from the north and west Wednesday into
Wednesday night. The remnants of Elsa then impact the region
Thursday into Friday. Please refer to the latest forecast and
track information on Elsa from the National Hurricane Center.
Weak high pressure briefly builds in this weekend before a warm
front moves in and stalls nearby early next week.
&&
.NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/...
Severe Thunderstorm Watch 336 in effect for the entire CWA
until 10pm. Convection continues to blossom across upstate NY
this afternoon. Convection should begin to translate south and
east over the interior 4-5 pm and then make its way through the
rest of the region from 6-9pm.
SBCAPE increasing significantly away from the immediate coast
with values 2500-3500 J/kg per SPC mesoanalysis. MLCAPE is also
increasing and running around 1500-2000 J/kg. There is a weak
cap between 800 and 900 mb, but this should weaken by the time
the convection reaches the region. Effective bulk shear while
relatively weak is expected to be around 25 kt across the
interior. Lower to middle level flow increases into this evening
with the middle level shortwave, which should help boost
shear/storm organization a bit.
Overall, the CAMs and high res guidance continue to be in good
agreement on the convection merging into a linear structure
as it moves towards the coast. There is always some question as
to how strong the convection will be as it nears the coast.
However, there is a pretty good signal in the CAMs for the
convection to maintain itself as it reaches the coast. It
appears that cold pool development along the leading edge of the
convection should help support the storms down to the coast.
The direction of movement is also a bit more favorable as well.
Marine inversion could be overturned with this environment and
allow for damaging wind gusts potential all the way to the
coast.
Damaging winds are the main threat with these storms although
it would not be surprising if one or two stronger cells produce
quarter sized hail. Flooding is not a major concern given the
overall movement of the thunderstorms, but minor urban flooding
cannot be ruled out.
The main line should be moving offshore by 01z with any trailing
stratiform rain potentially lingering another hour or so near the
coast. Dry conditions will then prevail overnight with decreasing
clouds. Patchy fog remains possible towards day break with the best
chance of development occurring across eastern Long Island and
southeast Connecticut.
Lows will range from the upper 60s inland to the lower 70s near
the coast.
&&
.SHORT TERM /6 AM WEDNESDAY MORNING THROUGH WEDNESDAY NIGHT/...
The heat advisory remains in effect through 8 pm Wednesday for all
zones except eastern Suffolk, southern Middlesex, and New London
counties. The atmosphere looks to dry out Wednesday morning to
allow for sufficient heating. While heights may lower a bit in
the morning behind tonight's departing shortwave, they look to
increase Wednesday afternoon. 850 mb temperatures overall look
similar to those observed on Tuesday. High temperatures and heat
indices overall look similar with actual air temperatures in
the upper 80s and lower 90s for most. The usual warmer spots in
urban NE NJ and the NYC metro could see highs in the middle 90s.
Dew points should remain quite high, generally in the upper 60s
to lower 70s translating to heat indices in the 95-100 range.
Some locations could see 100-102 in urban NE NJ. It would also
not be surprising if a few isolated locations away from the
shore see a heat index around 95 where there is no advisory.
The next concern will be with potential convection late Wednesday
afternoon into Wednesday evening. There does not appear to be
a well defined shortwave and guidance is not as robust as it
has been with Tuesday's convective development. Shear also looks
to be a bit weaker. Convective initiation may also occur late
in the day or in the evening, especially north and west of the
coast. SPC does have a marginal risk of severe thunderstorms
with the main threat being an isolated severe wind gust. The
convective mode appears to be pulse with some potential
multicell clusters. Confidence is relatively low on the
overall coverage however. A slow moving cold front does near
the region late in the day, which could enhance surface
convergence and act as a focus for development. Height falls
aloft and the frontal boundary lingering near the area at night
will support maintaining a chance of showers and thunderstorms.
&&
.LONG TERM /THURSDAY THROUGH TUESDAY/...
Moderate to heavy rain is forecast near the end of the week.
A mid level trough over the Great Lakes coupled with a surface
frontal system interact with the remnants of Elsa late Thursday
into Friday. Southwest flow aloft from the approaching trough
draws deep moisture from the subtropics Thursday into Friday as
it shifts east into New England, increasing PWATs to around 2
inches. NHC forecast track has Elsa making its closest approach
to Long Island Friday morning. This combination could help set
up a predecessor rain event over the Tri State Area late
Thursday into Thursday night. Chances of this will be enhanced
by moisture convergence along frontal boundary and synoptic
scale lift from an approaching right-rear quadrant of an upper
jet streak. Confidence is still only moderate at best as models
typically underestimate rainfall and the placement of its axis
in these situations, but best estimate is that 1-3 inches of
rainfall with locally higher amounts are possible here by the
end of Friday morning. See the hydrology section for more
details. It could become breezy mainly along coastal sections
Thursday night into Friday, but overall, winds are a lower
concern with this event. And regardless of Elsa's track, it is
likely that strong rip currents will occur along with potential
coastal impacts for later this week.
The flow aloft on Saturday begins as cyclonic with the upper
trough axis still nearby, but then flattens through the rest of
the weekend. This will allow for high pressure to build in
weakly at the surface, but probably with a stationary front not
too far to our south. Saturday is primarily dry, but cannot rule
out a diurnal shower/TSTM with the flow aloft still somewhat
cyclonic along with the potential of a shortwave adding
mechanical lift to any CAPE that builds up during the day.
Models disagree regarding our rain chances on Sunday with the
potential of overrunning precipitation, but kept PoPs on the
lower side. Upper ridging helps keep a lid on showers/convection
on Monday, so anything that occurs should be isolated in
nature. The boundary to our south then lifts north Monday night
into Tuesday. Still can't rule out a shower Monday night, but
chances increase Tuesday afternoon as we're progged to be in the
warm sector with greater instability.
High temperatures through the long term generally in the 80s,
however some areas in NE NJ could top 90 degrees on Thursday with
the potential of needing to extend the heat advisory for another
day.
&&
.AVIATION /20Z TUESDAY THROUGH SUNDAY/...
A pre-frontal trough approaches this eve, as high pressure
remains over the Western Atlantic.
Mainly VFR outside of tstms. Potential for a line/cluster of tstms
to approach or develop overhead before moving through through the
terminals between 21z and 02z. MVFR/IFR possible, along with heavy
downpours and strong winds gusts of 40-50 kt. Hail also possible.
VFR conditions return after 02z, though patchy fog and MVFR
visibilities may be possible overnight. VFR again on Wed with chcs
for tstms late in the day. VCTS was carried for SWF.
Moderate swly winds diminish overnight. Light s to sw flow on Wed.
Winds will be stronger in and around tstms.
NY Metro (KEWR/KLGA/KJFK/KTEB) TAF Uncertainty...
Shwrs and tstms likely late this aftn into this eve. Best timing
attm is 22-02Z. Low potential for tstms to reach the arpts earlier,
but vcts may linger a few hours aft 2Z, especially JFK.
Winds will be erratic and stronger invof tstms this aftn and eve.
.OUTLOOK FOR 18Z WEDNESDAY THROUGH SATURDAY...
.Wed...Mainly VFR with late day shwrs and tstms possible.
.Thu...Mainly VFR with late day shwrs and tstms possible.
.Fri...MVFR or lower possible. Locally hvy rain and embedded tstms
possible.
.Sat...Mainly VFR but some shwrs and tstms possible.
.Sun...VFR.

.MARINE...
Relatively strong S-SW flow this evening will continue with SCA
gusts around 25 kt on the ocean through the first half of the
night. A line of thunderstorms moving across the waters from
around 22-02z, which could produce wind gusts up to 50 kt. Ocean
seas will be 5-6 ft through tonight, then subside Wednesday
morning. The SCA will remain in effect on the ocean through 10z
Wednesday. A slightly weaker pressure gradient Wednesday into
Wednesday night will lead to conditions below SCA levels.
Southerly winds ahead of Elsa's approach begin to increase on
Thursday with peak winds probably on Friday as they shift east, then
north behind the weakening system. At least SCA conds probably
develop on the ocean waters Thursday night into Friday with a chance
that seas are already reaching 5 ft as early as Thursday afternoon.
Please refer to the latest forecast and track information on Elsa
from the National Hurricane Center. Lighter offshore winds then
follow for Friday night and Saturday with seas slowly subsiding.
Winds will be even lighter on Sunday with weak high pressure over
the area.
&&
.HYDROLOGY...
Minor flooding is possible with any storms this evening and
then again Wednesday into Wednesday night.
Flooding is possible late Thursday through Friday with periods of
rain and potential thunderstorms. 1 to 3 inches of rainfall with
locally higher amounts will be possible during this time. The more
likely impacts from this will be poor drainage/urban flooding. There
is also at least a low chance of flash flooding and flooding of
smaller rivers and streams as well.
&&
.TIDES/COASTAL FLOODING...
There remains a high risk of rip currents at ocean beaches through
Thursday. Surf height of around 4 ft is expected through Thursday
with long period south-southeast swells. Dangerous rip currents are
likely to continue on Friday.
