Area Forecast Discussion
National Weather Service New York NY
339 PM EDT Fri Jun 30 2017

.SYNOPSIS...
A warm front remains well to the north through Saturday as high
pressure sits over the western Atlantic. A cold front moves
across late Saturday night into Sunday. The cold front lingers
across the area on Sunday, followed by another cold front
crossing the area on Monday. High pressure then builds in from
the northwest on Tuesday, before sliding offshore Wednesday
night. The next system approaches the area for Thursday into
Friday.

&&

.NEAR TERM /UNTIL 6 AM SATURDAY MORNING/...
Initially, convection will be the near term concern into this
evening. Wind shear in the 30-40 kt range will allow for some
intensification, although greatest instability resides just
north of the CWA. Upstream thunderstorms should track across nw
zones, then possibly the northern portion of the CWA through
this evening, weakening as diurnal heating ends, and as
convection cools the boundary layer. Thereafter, any convection
will be isolated overnight due to lack of any additional
trigger, other than possible weak shortwaves embedded in upper
westerly flow.

Warm and humid conditions are anticipated, and with plenty of
cloud cover, lows should not fall further than the upper 60s to
lower 70s.

Dangerous rip currents are expected at the ocean beaches into
this evening. A high rip current risk remains in effect.

&&

.SHORT TERM /6 AM SATURDAY MORNING THROUGH SATURDAY NIGHT/...
Persistent S/SW flow Saturday, and lowering of heights, along
with approach of a cold front will set the stage for showers and
thunderstorms, with slightly higher coverage across the CWA.
Once again, marine eastern zones will observe enough stability
to keep thunderstorms to a minimum.

Coverage of showers/thunderstorms will increase from
isolated/scattered in the morning, to numerous in the
afternoon/early evening.

These showers and storms move across the area at night, as the
cold front passes. Clouds and showers/storms will prevent the
temperatures from reaching 90, but warm 80s anticipated, with
mid/upper 70s eastern zones of Long Island and southeast CT.

At night, lows once again will be in the upper 60s to lower 70s.

Dangerous rip currents are expected at the ocean beaches once
again Saturday due to strengthening southerly wind and rough
seas/swells. A high rip current risk has been issued for
Saturday.

&&

.LONG TERM /SUNDAY THROUGH FRIDAY/...
Models are in good agreement to start the period with the upper
level trough remaining over the northeast on Sunday before the
trough axis shifts offshore on Monday as surface high pressure
begins to build in from the northwest.

The cold front that crossed the area Saturday night will linger and
ultimately wash out over the region during the day on Sunday. The
atmospheric column dries out quickly, so other than a few leftover
showers and storms Sunday morning, the majority of the day should
remain dry despite the boundary in the area. As the trough axis
shifts eastward on Monday, a shortwave rounding the base of the
trough could help spark a few showers and thunderstorms Monday
afternoon, but the best dynamics remain well north of the region.

High pressure then builds in from the northwest, keeping the area
dry on Tuesday and into the first part of the day on Wednesday. As
the high moves offshore during the day on Wednesday, the next
frontal system will approach the region from the southwest. While
the exact details remain uncertain, there is general agreement with
the idea of an area of low pressure approaching the region during
the day on Thursday before exiting the area on Friday. This would
bring a chance of showers and thunderstorms back to the
area on Thursday into Friday.

Temperatures will remain near to a few degrees above normal through
the period, with daytime highs generally in the 80s and overnight
lows in the mid 60s to lower 70s. Sunday looks to be the warmest
day, with daytime highs around 90 in the city and in the mid 80s
elsewhere.

&&

.AVIATION /19Z FRIDAY THROUGH WEDNESDAY/...
Mainly VFR through this evening except where showers and
thunderstorms occur. Best chance for showers and thunderstorms
remains north and west of city terminals near KSWF and KHPN.
Given satellite and radar trends, will include TS in the TAF at
these locations and VCTS elsewhere. Further...HRRR model now
shows widespread showers and possible thunderstorms making it's
way to portions of southern CT later this evening so will expand
chc at KBDR and KGON. There is even a small chance some activity
crosses city terminals/LI after 22z but oceanic influence should
minimize activity. Will need to monitor radar trends and update
as necessary.

SW winds 10-20 kt backing to the S with gusts mostly 20-25 kt.
Winds diminish aft 00z.

Third night of southerly flow with increasing low level moisture
should allow for MVFR to IFR stratus to develop aft 06z. Higher
chc for IFR KJFK/KLGA/KISP/KHPN/KGON.

     NY Metro Enhanced Aviation Weather Support...

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

KJFK TAF Comments: Low chc of showers and thunderstorms aft 21z.

KLGA TAF Comments: Low chc of showers and thunderstorms aft 21z.

KEWR TAF Comments: Low chc of showers and thunderstorms aft 21z.

KTEB TAF Comments: Low chc of showers and thunderstorms aft 21z.

KHPN TAF Comments: Chc of showers and thunderstorms aft 21z.

KISP TAF Comments: Timing of stratus tonight may be off 1 or 2
hours.

.OUTLOOK FOR 18Z SATURDAY THROUGH WEDNESDAY...
.Saturday morning...MVFR to IFR lifts to VFR by late morning.
.Saturday afternoon-Sunday...Chance showers/thunderstorms with
MVFR or lower conditions possible. SW gusts near 20 kt with
higher gusts possible near thunderstorms Saturday afternoon and
evening.
.Monday...Mainly VFR early. Afternoon MVFR possible late day or
evening showers and thunderstorms. SW gusts near 20 kt.
.Tuesday AND Wednesday...VFR. North winds Tue becoming variable
and then southerly by Wednesday 5-10 kt.

&&

.MARINE...
High pressure remains over the Atlantic tonight and Saturday. A
cold front approaches Saturday and slowly moves across Saturday
night.

SCA has been extended over the ocean waters through Saturday
evening. Gusty 20 to 25 kt winds continue into this evening, but
diminish somewhat overnight and into Saturday morning. By
afternoon, these winds pick up yet again to 20 to 25 kt and
continue into the evening. As the front moves overhead, winds
diminish Saturday night.

Ocean seas remain in the 3 to 7 ft range tonight, and Saturday.
Seas subside Saturday night per guidance.

Non ocean waters remain below SCA thresholds through Saturday
night.

Winds and seas are expected to remain below SCA criteria into mid-
week as high pressure builds over the waters and the pressure
gradient relaxes.

&&

.HYDROLOGY...
Any shower or thunderstorm through Saturday night may produce
minor urban flooding. However, no widespread hydrologic impacts
are anticipated.

No hydrologic impacts expected Sunday through the middle of next
week.
