Area Forecast Discussion
National Weather Service New York NY
447 PM EDT Wed Jul 7 2021
.SYNOPSIS...
A cold front slowly approaches from the north tonight, stalling over
the area. The front then lifts back north on Thursday. Elsa
approaches us through the day Thursday and impacts the region mainly
Thursday night and 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 pushes north of the area early next week.
&&
.NEAR TERM /UNTIL 6 AM THURSDAY MORNING/...
First threat of showers and thunderstorms is early this evening,
well ahead of an approaching cold front from the north. Storms will
be potentially severe during this time with plenty of CAPE early on.
Main threat from these storms would be with wind gusts, but large
hail is also not out of the question. For the rest of the night, the
cold front eventually moves into the Tri-State area. A shortwave
also approaches from the SW late at night. With some elevated CAPE
around, this will maintain chance of showers and storms overnight.
Warm and muggy conditions continue overnight with lows generally in
the 70s.
&&
.SHORT TERM /6 AM THURSDAY MORNING THROUGH THURSDAY NIGHT/...
The stationary front shifts back north as a warm front in the
morning. This will lessen the potential of boundary-influenced
moisture convergence in the area. Shower chances will however
increase through the day along with a chance of thunderstorms. Best
chances will be over the NW zones where synoptic scale lift
increases late in the day ahead of the right-entrance quadrant of an
upper jet streak. This jet streak will probably have greater
influence over the NW half of the forecast area into Thursday night.
PWATs increase to around 2 inches so heavy downpours will be
possible. Then late at night with the approach of Elsa, even greater
chances of heavy downpours. A flash flood watch now begins during
the late night hours for all but eastern LI and SE CT.
Regarding heat headlines, have gone a little below NBM deterministic
guidance for high temps since based on temps aloft and partly to
mostly cloudy conditions. Combined with the dewpoints, heat index
values for portions of Union and Essex Counties reach 95-97, but not
more than half than any one forecast zone. Not enough confidence to
extend the heat advisory in the areas into Thursday, especially
considering the potential cloud cover.
&&
.LONG TERM /FRIDAY THROUGH WEDNESDAY/...
Elsa or remants of Elsa pass over or nearby the forecast area
Friday morning with the Flash Flood Watch continuing through
the morning hours. See the hydrology section for more details on
impacts from the rain. Winds will pickup for a short time
Friday morning as they shift more east, then finally west to
northwest in most areas by noon. Rain chances and wind then
drop off in the afternoon and evening hours. Please refer to
the latest forecast and track information on Elsa from the
National Hurricane Center.
Upr ridge builds over the Atlc thru the long term. This will
result in a warming trend and increasing chances for shwrs and
tstms. Southwest flow aloft tends to favor interior/wrn zones
for best pcpn chances, but there is some uncertainty wrt the the
position of the ridge and the track and timing of the
associated upr low. The cwa could be close enough to the storm
track on the nrn periphery of the ridge to produce several
rounds of active wx. On the other hand, a drier scenario would
favor a few airmass tstms each day mainly over the interior. For
now, the blended approach was taken and the NBM followed.
&&
.AVIATION /20Z WEDNESDAY THROUGH MONDAY/...
A weak cold front approaches the region from the north this evening,
then weakens over the area on Thu.
Mainly VFR thru the TAF period. Sct tstms are expected to develop
late into this eve N and W of the terminals. It is possible tstms
merge and track swd thru the area aft 00Z, but confidence is very
low attm. It is more likely that sct tstms continue to develop from
SW to NE thru this eve, producing either direct or indirect impacts
to the NYC arpts. VCTS has been carried in the TAFs for this.
Some patchy fog is possible in the outlying arpts aft 5Z, but the
prob was too low to include in the TAFs.
Increasing chances for shwrs and tstms on Thu. VCSH was included in
the TAFs aft 18Z.
SW winds this eve, then winds become lgt and vrb overnight.
Strengthening S/SE flow on Thu.
NY Metro (KEWR/KLGA/KJFK/KTEB) TAF Uncertainty...
Winds will be backed more to the S at JFK thru 00Z. Amendments
possible for tstm timing and coverage aft 22Z all arpts.
.OUTLOOK FOR 18Z THURSDAY THROUGH MONDAY...
.Thu...Mainly VFR with shwrs and tstms possible.
.Fri...Elsa impacts possible. MVFR or lower likely. Locally hvy rain
and embedded tstms possible.
.Sat...Mainly VFR but isold shwrs and tstms possible.
.Sun...Chances for shwrs and tstms.
.Mon...Chances for shwrs and tstms.

&&
.MARINE...
Sub-advisory conditions remain on all waters tonight. Southerly winds
ahead of Elsa's approach then begin to increase on Thursday into
Thursday night. At least SCA conds are probable Thursday
evening with potentially stronger winds for late Thursday night
into Friday as Elsa passes through or nearby.
Please refer to the latest forecast and track information on Elsa
from the National Hurricane Center.
Seas on the ocean will subside on Sat, with waves blw 5 ft expected
by Sat ngt attm. Winds will be blw sca lvls on all waters Sun-Tue.
Seas on the ocean may touch 5 ft at times Sun and Mon.
&&
.HYDROLOGY...
Minor flooding is possible with any storms this afternoon and
evening.
Flooding is possible late Thursday through Friday with periods of
rain and potential thunderstorms. 2 to 3 inches of rainfall
with locally higher amounts possible during this time. Areas of
poor drainage/urban flooding are likely, with potential for
some areas of flash flooding and flooding of fast reacting
small rivers and streams.
No hydrologic concerns from Saturday through Wednesday.
&&
.TIDES/COASTAL FLOODING...
There remains a high risk of rip currents at ocean beaches through
Thursday. Surf height of around 3 to 5 ft is expected through
Thursday due to 3 to 5 ft southerly wind waves mixed with
background long period SE swells. Dangerous rip currents are
likely to continue on Friday.
