What forecasters said that day

The local office's own words before this special weather statement went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS New York, NY wrote its last area forecast discussion before this special weather statement went out at Jul 8, 4:01 PM EDT, 1 hour 2 minutes earlier.

Area forecast discussion, Jul 8, 4:01 PM EDT, 1 hour 2 minutes before
Area Forecast Discussion
National Weather Service New York NY
401 PM EDT Thu Jul 8 2021

.SYNOPSIS...
A stalled front remains near the region tonight. Elsa then
approaches from the south this evening and impacts the area
late tonight into Friday morning. Please refer to the latest
forecast and track information on Elsa from the National
Hurricane Center. A trailing cold front crosses the region
Friday night. Weak high pressure briefly builds in this weekend
before a warm front moves in and pushes north of the area early
next week.

&&

.NEAR TERM /THROUGH FRIDAY/...
Severe thunderstorm watch 351 remains in effect for the entire
area until 9 pm. The main threat with these storms is damaging
winds and large hail, but an isolated tornado threat does exist,
especially along the frontal boundary in the vicinity of the
NYC metro, NE NJ, and Lower Hudson Valley.

There is also a flash flood threat as cells train over the same
area and ride along the frontal boundary. The flash flood watch
is now in effect for the entire area through Friday morning.

Showers and thunderstorms remain possible this evening with the
greatest threat across the western two thirds of the area.
Slightly cooler and more stable conditions reside across eastern
Long Island and southeast Connecticut. However, given the
proximity of the surface boundary, a strong to severe cell
cannot be ruled out.

There is also synoptic support to help sustain convection into
this evening with the region lying within the right entrance
region of an upper jet to the north. Probabilities increase from
west to east through this evening.

Attention then turns to Elsa which will track towards the region
tonight. There has not been much change to overall thinking with
impacts. The greatest threat continues to be from heavy rainfall
and flooding. The heaviest rainfall looks to fall from 06-12z
Friday, with the HREF continuing to support low end
probabilities of >1" per hour across NYC and the Lower Hudson
Valley for a few hours Friday morning. As mentioned above, the
Flash Flood Watch has been extended to include all of eastern
Long Island and southeast Connecticut.

Winds still appear to be a limited impact, but there are some
indications of potential of wind gusts 35-45 kt across eastern
Long Island and southern CT as the remnant circulation makes its
nearest approach Friday morning. Soundings also indicate
potential for deep mixing on the backside of the center, which
could support a brief period of gusty winds, 20-35 kt.

Otherwise, model guidance is in excellent agreement on the
remnants of Elsa departing the area to the north east after
14-16z. Conditions should rapidly improve behind Elsa with
subsidence in its wake. Temperatures should rebound well into
the 80s across the region, with potential for around 90 degrees
in urban northeast NJ.

A trailing cold front will be approaching late in the day. This
could bring a redevelopment of showers and thunderstorms well
north and west of NYC. Some concern as to how quickly they will
develop, but given destabilization in the afternoon and
departing subsidence, feel there could be convection developing
north west of NYC before 6 pm.

&&

.SHORT TERM /FRIDAY NIGHT/...
Upper shortwave axis will remain to the west Friday evening. The
trailing cold front looks to settle over the region in the
evening. CAMS are in a bit of disagreement on the coverage of
convection. Do not think it is out of the question for another
line, or broken line of showers and storms to cross the region
in the evening. Any stronger storm could bring damaging wind
gusts. Convection that does develop should be moving offshore
after midnight with the passage of the cold front.

&&

.LONG TERM /SATURDAY THROUGH THURSDAY/...
No major changes to the long term.

Upper ridge builds over the Atlantic through the long term.
This will result in a warming trend and increasing chances for
showers and thunderstorms. Southwest flow aloft tends to favor
interior/western zones for best chances, but there is some
uncertainty regarding the the position of the ridge and the
track and timing of the associated upper low to the north and
west. The CWA could be close enough to the storm track on the
northern periphery of the ridge to produce several rounds of
active wx. On the other hand, a drier scenario would favor a few
airmass storms each day mainly over the interior. For now, the
blended approach was taken and the NBM followed.

&&

.AVIATION /20Z THURSDAY THROUGH TUESDAY/...
Mostly VFR through much of the day today, however IFR/MVFR for some
of the non-city terminals. Showers and TSTMs mainly from around the
city to points N and W this aftn.  Remnants of Tropical Storm Elsa
approach this evening and will result in widespread moderate to
heavy rain with embedded thunderstorms after around 06Z Friday with
IFR conditions or lower. Can't rule out at least an iso TSTM Friday
aftn.

Winds S 10 to 15 kt with gusts to 20 kt possible. Winds become more
SE late, then E tonight with the approach of the remnants of Elsa.
Gusts after 07-09Z Friday locally up to 30kt mainly along the
immediate coast... KISP, KJFK, KGON, KBDR. With the center of the
tropical system moving to the east of the terminals, winds will turn
to the north toward daybreak, then northwest and west Friday
morning.

     NY Metro (KEWR/KLGA/KJFK/KTEB) TAF Uncertainty...

Amendments possible to include thunder for KJFK and KLGA this
afternoon as there is uncertainty in placement of thunderstorm
development this PM.

.OUTLOOK FOR 18Z FRIDAY THROUGH TUESDAY...

.Fri PM...VFR. Iso/sct TSTMs.
.Sat...Mainly VFR but isold shwrs and tstms possible.
.Sun - Tue... Mostly VFR, but...Chances for MVFR in shwrs and tstms.

Detailed information, including hourly TAF wind component forecasts,
can be found at: https:/www.weather.gov/zny/n90

&&

.MARINE...
Sub-advisory conditions remain on all waters into this evening.
Southerly winds ahead of Elsa's approach then begin to increase
tonight. Seas will build and winds increase through tonight.
Tropical storm conditions are then possible on the eastern
waters as Elsa passes through or nearby Friday morning. Have
issued an SCA for the Western Sound and NY Harbor as there could
be some gusts 25-30 kt late tonight into early Friday. Please
refer to the latest forecast and track information on Elsa from
the National Hurricane Center. Winds and seas slowly subside
late Friday into Friday night as Elsa departs well to the north
and east.

Seas continue to subside on Sat, with waves below 5 ft expected
by late day. Winds will be below SCA levels on all waters Sun-
Tue. Seas on the ocean may touch 5 ft at times Sun and Mon.

&&

.HYDROLOGY...
Flash flooding is possible with any storms this afternoon given
the moist airmass in place. Isolated flash flooding is possible
across northeast New Jersey and the Lower Hudson Valley.

Flooding is then again possible late tonight through Friday
morning with periods of heavy rain and potential thunderstorms,
2 to 3 inches of rainfall with locally higher amounts possible
during this time with the remnants of Elsa. Areas of poor
drainage/urban flooding are likely, with flash flooding and
flooding of fast reacting small rivers and streams possible.

Possible showers and thunderstorms Friday evening may also bring
at least minor urban flooding.

No hydrologic concerns from Saturday through Thursday.

&&

.TIDES/COASTAL FLOODING...
There remains a high risk of rip currents at ocean beaches through
Friday. Surf height of around 6 ft is expected on Friday long
period SE swells. There is a moderate risk of rip currents for
NYC and Nassau ocean beaches Saturday and a high risk for
Suffolk ocean beaches.
