Area Forecast Discussion
National Weather Service New York NY
832 PM EDT Tue May 28 2019

.SYNOPSIS...
Low pressure will send a warm front across portions of the area
this evening, then passes to the east late tonight followed by a
cold frontal passage. Another wave of low pressure will track
along the front on Wednesday, passing near or just south of the
area Wednesday night. The boundary lingers south of the area
into Thursday. A cold front then moves through the region Thursday
night, with brief high pressure returning for Friday into
Saturday. Another frontal system will move through on Sunday,
followed by building high pressure into early next week.

&&

.NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/...
Based on radar and stlt, the tstm risk has been slightly slowed.
Otherwise, the fcst is on track. Warm front approaching from
the southwest separates a moderately to highly unstable airmass
to the west and a stable marine layer to the east. As low-level
winds continue to veer to the south this evening and the warm
front works into portions of the area, ingredients will be in
place for the development of scattered to numerous strong to
severe thunderstorms. Latest HiRes guidance shows boundary
setting up across NYC metro, Long Island, and portions of the
Lower Hudson Valley. This combined with 0-6 km deep-layered
shear of 40-50kt and 0-3 SRH value around 400, supports rotating
updrafts and strong mid-level mesos should convection be
realized. The main threat will be damaging winds and large hail,
but isolated tornadoes are a possibility, especially just west
of the NYC metro where surface based instability will be
highest. Of course, where the boundary resides this evening will
be key player to where the damaging winds and tornados can be
realized. As the cells propagate east, they will become elevated
due to the marine layer. Large CAPES values out east and the
maintenance of the low-level cold pool though could briefly
scour out the marine layer even for areas just east of the NYC
metro.

Most likely timeframe for the convection is between 6-10 pm,
with the Lower Hudson Valley and interior northern NJ on the
earlier side of that range. Convection looks to initiate north
and west of the area in association with the boundary across
the NY/PA border, then drops south and east of Long Island
toward midnight.

Localized heavy rainfall is likely with the strongest activity,
but a WNW storm motion in excess of 30 kt should limit the
flash flood threat.

Cold front passes through by daybreak with lows in the mid 50s
to lower 60s, slightly above normal.

There is moderate risk for rip currents at the Atlantic beaches
this evening, except for high across the beaches from Nassau
west due to moderate S/SE winds and building waves.

&&

.SHORT TERM /6 AM WEDNESDAY MORNING THROUGH WEDNESDAY NIGHT/...
Upper air pattern continues to feature a ridge over the
southeast, a trough over the central plains, and an upper
vortex descending south across Hudson Bay. The will continue
to send a series of waves from west to east across the Midwest
and Ohio Valley states into the region. The next in the series
will approach tomorrow afternoon and pass near or just south
of the area Wednesday evening. Preferred a more southward track
at this time, in line with the NAM, due to the subtle, low
amplified flow associated with these systems. Have maintained
rain chances late tomorrow afternoon into the evening, but
have begun to trend lower. This track also will keep the area
in a more stable region with the severe weather threat south of
the region.

Should see some sun on Wednesday before the next system moves in
with highs and lows just above normal.

There will be a moderate risk for rip currents across the
Atlantic beaches Wednesday.

&&

.LONG TERM /THURSDAY THROUGH TUESDAY/...
The long term period begins with a large closed low pressure system
across SE Canada, strong high pressure over Florida, and a upper
trough/cutoff low out west. As a result, the pattern will be
somewhat stagnant into the weekend, although the ridging over the
south will shift into the Gulf of Mexico with a piece of the
Canadian low tracking through the Canadian Maritimes and another
resulting in an amplifying trough down the eastern seaboard and
eventually tracking through northern New England early next week.
Model guidance is in good agreement through the first half of the
weekend with differences in timing and amplitude of the upper trough
late in the weekend and into next week.

At the sfc, a few lingering showers are a possibility Thu morning
with a stationary frontal boundary and a departing low pres system
in the vicinity. A series of disturbances then approach the area,
both from the north tied to a stronger short wave trough, and from
the west with a convectively induced vorticity maximum associated
with an upper trough moving through the Midwest. The attendant
surface low is expected to track roughly over the Ohio Valley, with
the warm front potentially moving northeastward into at least part
of the region Thu afternoon and evening. Any severe potential will
depend on the track of the front, but at the very least rainfall
potential will increase into the overnight as a shortwave rounding
the base of the upper low to the north moves through, tracking a
cold front through the area.

Brief subsidence and high pressure then returns for Friday, but will
be short-lived before another system approaches late Saturday into
Sunday night. Cyclonic flow lingers into the early week, so at least
isolated showers will be possible.

Throughout the extended, highs will be above climatological normals
across northeastern New Jersey into the lower Hudson Valley, while
elsewhere should be closer to normal. Lows will largely be above
normal until early next week.

&&

.AVIATION /01Z WEDNESDAY THROUGH SUNDAY/...
Low pressure with an associated warm front and cold front will move
across tonight. The frontal boundary becomes stationary late tonight
into Wednesday with another low along the front that will
approach late in the TAF period.

For this evening, expecting scattered showers and thunderstorms with
higher chances for them across NYC terminals as well as KHPN and
KSWF. Conditions initially mainly VFR with isolated MVFR and IFR.
There will be a chance of MVFR at times with showers and
thunderstorms. Gusty winds and hail are possible in any
thunderstorm that develops. Mainly dry overnight into Wednesday
with mainly VFR but especially east of city terminals, MVFR to
IFR stratus are forecast to develop. Late morning into the
afternoon Wednesday, VFR returns for all terminals.

Winds are quite variable for terminals this evening. Winds gradually
turning more S-SW tonight after the warm frontal passage with
eventually a turn more NW late tonight behind the cold front. Wind
speeds will be near 10 kts or less. Since flow will be light
Wednesday, expecting sea breezes to form in the afternoon for
coastal terminals.

Between 1/3 and 1/2 of rainfall is expected Thu into Thu night.
Locally higher amounts are possible in any convection, which could
