Area Forecast Discussion
National Weather Service New York NY
230 PM EDT THU AUG 11 2016
.SYNOPSIS...
Bermuda high pressure will remain across the Western Atlantic
through the weekend...bringing a heat wave to the Tri-State
Region. A cold front approaches on Sunday and moves across
sometime early next week.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
Heat products have been expanded and extended through the weekend.
Scattered thunderstorms are rapidly developing and will impact the
forecast area through at least 4-6 pm.
The ridge in the mid levels further suppresses slightly through
the day. At the surface, the Bermuda high persists with a
continuing SW flow, further establishing the very warm and humid
airmass encompassing the region.
On a small scale, there is a slight perturbation and inherent subtle
shortwave along the periphery of the ridge that will be moving
across during the day. This along with any differential heating as
well as sea breeze boundaries will allow for increased convergence
and hence, increase the potential for showers and thunderstorms.
There is pretty good multi-model agreement with precipitation
throughout today, but exact timing and placement will be uncertain.
This uncertainty will make it difficult to pinpoint when and where
exactly showers and thunderstorms will be likely. However, there
will be a 30-50 percent chance of them, higher out west, where there
will be more instability.
Borderline moderate to high risk of rip current through today
with residual 3 to 4 ft s/sw wind waves. With a couple of
supplemental long period 1 ft se swells the surf zone forecast
remains leaned towards a high risk.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH FRIDAY NIGHT/...
The ridge further flattens tonight and then the height becomes
nearly steady at 500mb Friday and Friday Night. Meanwhile, a mid
level low moves east in Manitoba tonight and into Ontario Friday and
Friday Night as it transitions to an open wave. On the large scale,
the longwave trough will be developing and approaching the
Northeast. The ridge in the local region starts to move more
offshore.
At the surface, the Bermuda high remains anchored keeping the region
locked into a SW flow and therefore establishing an increasingly
warm and tropical airmass. Lows both tonight and Friday night used
the warmer side of guidance, ECS for tonight and MAV for Friday
night. For highs Friday, they were also a blend of MAV/MET/ECS.
As far as convection is concerned, chance for showers and
thunderstorms will be lower tonight and Friday Night overall with
the lower instability and higher Friday with daytime heating and
inherent gain of instability. Similar to Thursday, the trigger
Friday will be a small subtle shortwave riding along the
periphery of the ridge as well as surface features of differential
heating and any sea breeze boundaries.
In terms of the airmass, it remains very warm and humid as dewpoints
stay in the low to mid 70s. Most lows tonight and Friday night only
drop into the mid to upper 70s. Friday features highs slightly
warmer than the previous day as likewise the 850mb temperatures from
multiple models also increases by approximate a degree C. This will
allow for slightly warmer temperatures with daytime mixing. With the
dewpoints still in the low to mid 70s, expecting a large part of the
region to see heat indices in the lower 100s.
&&
.LONG TERM /SATURDAY THROUGH THURSDAY/...
Oppressive heat and humidity continues through Sunday as Bermuda
ridging remains in control.
Max temperatures in the lower to possibly mid 90s are expected
for a majority of the region through Sunday...with dewpoints in
the mid 70s. Widespread heat indices around 100 degrees are
forecast with some areas such as Northeast NJ and NYC possibly
reaching and slightly exceeding excessive heat warning values of
105 degrees on Saturday...and possibly Sunday afternoon...although
not as confident and will depend on the amount of cloud cover
Diurnal instability and any differential heating due to cloud
cover in addition to sea breeze convergence boundaries will allow
for scattered showers and thunderstorms to develop Saturday,
mainly in the afternoon to early evening hours and for NYC metro
and interior each day. Tropical moisture across the region will
allow any thunderstorms to produce torrential rainfall, and weak
steering flow will portend an increased flash flood threat as
thunderstorms will be slow moving. Increasing coverage of showers
and thunderstorms is possible Sunday and Sunday Night as upper
level trough and frontal boundary approach.
Solutions begin to diverge on Sunday with regards to the southward
progression of the frontal boundary. The GFS is faster moving it
through Sun eve...although not as fast as previous runs...and also
appears to be having convective feedback issues. Have stuck
closer to the ECMWF which has had more run to run continuity...but
is a more pessimistic forecast with the front becoming hung up
over the area on Monday and possibly resulting in unsettled
weather into the middle of next week. This will maintain chance
for widespread shower and thunderstorm activity. Since
considerable uncertainty exists with the location of the frontal
boundary...this is a low confidence forecast. This will also have
an impact on the temperature and dewpoint forecast.
The boundary should eventually shift to the south of the local
area...but it may not be until the second half of the week.
&&
.AVIATION /19Z THURSDAY THROUGH TUESDAY/...
Unsettled weather on tap for this afternoon and evening, mainly
for KNYC and northern terminals. Primarily a VFR forecast, but
conditions will briefly dip to MVFR, possibly IFR, should TSRA
pass through the terminals. Think best chances will be from
21-01Z, but with storms already developing, cannot rule out
convection starting to impact KNYC terminals after 19Z. KSWF may
be impacted prior to that.
Low confidence on development of fog tonight, except for
terminals away from KNYC. Will TEMPO reductions in VSBY there late
tonight and into Friday morning.
Models indicating a wave of +SHRA around daybreak Friday,
persisting through the morning departure bank. For now, will carry
a PROB30 group for MVFR conditions in +SHRA. IFR conditions
possible.
W-SW winds 8-12 KT, and S winds 8-12 KT for coastal terminals due
to sea breezes will become SW 5-7 KT this evening. SW flow
persists tonight through Friday, and strengthens Friday
afternoon.

.OUTLOOK FOR 18Z Friday through Tuesday...
.Friday afternoon through Monday...Mainly VFR. Isolated to
scattered +SHRA/TSRA may result in brief IFR conditions.
.Tuesday...VFR. MVFR or lower possible Tuesday night.
&&
.MARINE...
Conditions on the forecast waters are expected to remain below
SCA thresholds for today and tonight. For Friday and Friday night
though, enough of a southerly fetch and a slight pressure gradient
increase will lead to potentially more SCA conditions for the
ocean with non-ocean waters staying below SCA thresholds.
SCA possible on the ocean waters Sat/Sat eve for marginal wind gusts
and seas. Gusts diminish Sat night...but a moderate SW flow should
keep seas elevated through early Sun morning. Sub-advsy conds are
then expected due to relatively light winds.
&&
.HYDROLOGY...
With precipitable waters remaining generally between 2 and 2.5
inches, any thunderstorms that develop through the weekend will
be capable of producing torrential rainfall. With storm motion
generally expected to be less than 20 kt, there will be the threat
of localized flash flooding from any slower moving strong storm.
