Area Forecast Discussion
National Weather Service New York NY
352 PM EDT Sun May 22 2022
.SYNOPSIS...
A cold front will pass through the area this evening. High
pressure will build in from the west. The high slides off shore
late Tuesday into Tuesday night and then remains off shore
through the middle of the week. A frontal system approaches the
area late in the week.
&&
.NEAR TERM /UNTIL 6 AM MONDAY MORNING/...
The main story this evening will be the passage of a cold front
and the scattered showers and thunderstorms that will preceded
the front. A few of these thunderstorms, could become strong to
severe, however the best chances for any severe storms will
remain north and west of the NYC Metro. Frontal forcing combined
with moderate to high instability will be the main ingredients.
Not expecting much organization due to weak wind shear. Once
daytime heating is lost and the convection works toward the
coast, any storms are expected to quickly dissipate. Will carry
some likely POPs west of NYC, but keep just chance POPs closer
to NYC and points east.
With respect to heat headlines, am going to go ahead and cancel
the heat advisory. Temperatures have been marginal and
temperatures will only fall through the remainder of the
evening.
Following the cold frontal passage this evening, winds become
northwesterly. A few occasional gusts up to 20 mph may be possible
overnight. Lows tonight fall into the 50s and lower 60s.
&&
.SHORT TERM /6 AM MONDAY MORNING THROUGH MONDAY NIGHT/...
Conditions will be more seasonable on Monday as high pressure
over the Great Lakes builds north of the area. This will result
in a northerly flow across the area on Monday that veers around
to the NE Monday night. The flow may weaken just enough in the
afternoon for seabreezes to develop.
One forecast uncertainty during this period will be the amount of
cloud cover as moisture from a frontal wave over the SE streams NE.
Some of the model blends continue to be aggressive with the cloud
cover. For now, will keep at least partly cloudy conditions at this
time. This could impact the temperature forecast a bit, but overall
highs on Monday should reach the lower and middle 70s. Monday night
lows fall into the 50s.
&&
.LONG TERM /TUESDAY THROUGH SUNDAY/...
Tranquil conditions expected through the middle of the week as
the center of high pressure pushes off the New England coast
late Tuesday into Tuesday evening. Aloft, the pattern will
generally be a zonal flow. Onshore flow thanks to a developing
maritime air mass during this time frame will keep temperatures
at or a few degrees below normal.
An upper level ridge begins to build over the western Great
Lakes region Tuesday night into Wednesday, which itself will be
ahead of a developing storm system in the middle of the country.
This upper level ridging will translate east through Wednesday
night, and a surface warm front will push through from the
southwest during the day Thursday. A feature to watch will be
the development of a weak area of low pressure or inverted
trough off the mid-Atlantic Coast. This could move northward
Wednesday night, and bring in more widespread light
precipitation than is currently forecast for Wednesday night
into Thursday morning. Right now, capped POPs at chance during
this time frame.
The passage of the warm front on Thursday will allow warmer air
to advect into the forecast area for Thursday and Friday. The
associated cold front will move through and push off shore on
Friday. Depending on the speed of the front, temperatures on
Friday could be a bit cooler if the front moves in sooner than
forecast. The ECMWF ensemble continues to show a large spread in
high temperatures for Friday. There continues to be timing and
strength issues with the cold front, with the ECMWF being
uncharacteristically more progressive than the other
deterministic models. However, a look at the ensemble models
shows a frontal passage late in the day Friday into Friday night
to be a reasonable solution.
Conditions are expected to be dry through Wednesday. Introduce
a chance of showers late Wednesday night with the potential of
the weak low/inverted trough moving into the area. It will then
remain unsettled from Thursday through the end of the work week
as the warm front moves through, then the cold front. Dry
conditions are expected by late Friday night.
&&
.AVIATION /20Z SUNDAY THROUGH FRIDAY/...
A cold front over central PA will continue to move east through
this afternoon and evening.
VFR conditions expected through this afternoon. Scattered
showers/tstms likely to approach the NYC/NJ metro terminals by 21Z.
MVFR or lower conditions and strong W/NW wind gusts (30kt+) will be
main concern with any thunderstorm development. Latest guidance has
showers/tstms weakening as they work closer to eastern terminals
later in the evening.
S-SW winds 12-15 kt this afternoon. Winds shift to the W/NW in
wake of cold frontal passage during the evening with gusts to 20
kt.
NY Metro (KEWR/KLGA/KJFK/KTEB) TAF Uncertainty...
Timing of showers and thunderstorms remains uncertain and may be off
up to 2 hours this evening.
.OUTLOOK FOR 20Z MONDAY THROUGH THURSDAY...
.Mon-Tue...VFR.
.Wed...Mainly VFR. MVFR or lower possible at times. Slight chance of
showers day. Chance of showers at night.
.Thu...MVFR or lower possible at times. Chance of showers.
Slight chance of thunderstorms north and west of NYC.
.Fri...MVFR possible in showers.

&&
.MARINE...
A cold front will push across the waters this evening. Any
convection this evening with the front looks to be scattered and
weakening. Behind the front, high pressure builds in north of
the waters. Sub-SCA conditions are anticipated through Monday
night.
With warm temperatures continuing into this evening, it is
important to remember that water temps remain rather cold, in
the 50s. A marine weather statement remains in effect to
highlight the dangers of swimming and being in waters this cold.
Winds and waves are expected to remain below SCA criteria from
Tuesday through Thursday with a weak pressure gradient in place.
Increasing southerly flow out ahead of an approaching cold
front may allow for gusts of around 25 kt on the ocean waters
for Friday and perhaps the eastern sound and Peconic and
Gardiners Bays. Waves on the ocean may build to 5 ft Thursday
night into Friday.
