Area Forecast Discussion
National Weather Service New York NY
118 AM EST Mon Dec 18 2023
.SYNOPSIS...
Strong low pressure along the Carolina coast approaches from
the south overnight and passes through the region Monday. The
low tracks north of the area Monday night. Low pressure moves
away from the area on Tuesday with high pressure building in.
High pressure will remain in control through next weekend.
&&
.NEAR TERM /THROUGH TODAY/...
Expect to see increasing rain coverage, heavier rainfall, and
stronger winds as the night progresses. The forecast remains on
track.
Deepening low pressure along the Carolina coast will continue to
track north along the eastern seaboard overnight. Timing and
track of the low remain fairly consistent with the previous
forecast. A strong low level jet to the east of the low will
track into the area, producing strong lift and moderate to
heavy rainfall overnight into the morning. Some of the highest
rainfall totals are expected across portions of northeastern New
Jersey into the lower Hudson Valley, and even into southwestern
Connecticut (Fairfield County) with strong southeasterly flow
enhancing lift on the upslope sides of the higher terrain.
Rainfall totals have increased slightly across these areas.
Weak elevated instability will also enhance rainfall, as
isolated thunder remains possible. A flood Watch remains in
effect tonight through Monday afternoon.
A period of high winds and strong gust also remain likely
overnight into the morning as a strong low level jet of 60-85kt
moves over the eastern regions. And a High Wind Warning remains
in effect for the coastal locations. With a slightly more
western track of the low and winds gusts possibly reaching
advisory levels farther west and north, have expanded the winds
advisory to include Eastern Bergen, Eastern Essex, and Eastern
Union Counties.
&&
.SHORT TERM /TONIGHT THROUGH 6 PM TUESDAY/...
The low will be north of the area by Monday night with a brief
break in precipitation. Wrap around moisture in the back side
of the low will maintain chance and slight chance probabilities
Monday night. With some colder air wrapping into the northwest
sections a few snow showers and flurries will be possible. There
may even be slight coating of snow in the higher terrain of
Western Orange County.
&&
.LONG TERM /TUESDAY NIGHT THROUGH SUNDAY/...
Upper level low over the eastern Great Lakes region will weaken
into a trough as it moves toward the forecast area. A weak area
of low pressure looks to form along the frontal boundary
offshore, and a blocking pattern will then set up as the trough
becomes an upper level low once again and will interact with the
weak surface low offshore, becoming vertically stacked by the
middle of the week. With a blocked pattern over the region, the
surface high that builds in late Tuesday into Tuesday night will
remain over the area through next weekend. The only chance for
any precipitation for this time frame is during the day on
Tuesday. This will be due to the trough aloft and one at the
surface that will move through. These features may provide
enough lift for some precipitation, however any precipitation
will be light. It will be cold enough well inland Tuesday
morning for some snow flakes to fall, or snow mixed with rain,
but little if any accumulation is expected.
The area will be on the eastern side of the high during much of the
week, with a northwest to northerly flow for much time. This will
lead to seasonable temperatures with highs in the 40s.
&&
.AVIATION /06Z MONDAY THROUGH FRIDAY/...
HIGH IMPACT AVIATION EVENT OVERNIGHT INTO MONDAY...
Deepening low pressure tracks up the East Coast through Monday.
Expect widespread IFR/LIFR conditions through morning with
improvement behind the departing surface low and cold front in
the afternoon. Conditions are forecast to improve to MVFR in the
afternoon, becoming VFR by late afternoon for all but KGON,
which could take into early Monday evening.
ESE winds will steadily ramp up overnight, increasing to
20-30kt G30-50kt, strongest along the coast. Slow improvement
late morning through the afternoon, with winds veering to S/SW
late morning, then W/NW around 20kt G30-35kt in the afternoon
into early evening. Winds will then gradually diminish and back
to the SW G20-25kt Monday evening.
...NY Metro (KEWR/KLGA/KJFK/KTEB) TAF Uncertainty...
Isolated 50 kt gusts overnight into the the morning (about 12Z),
especially at KJFK and KLGA.
Gusts after 13Z could be more occasional than frequent until
low passes to the east in the early afternoon.
Timing of flight categories could vary by 1-2 hours.
OUTLOOK FOR 06Z TUESDAY THROUGH FRIDAY...
Monday Night: Mainly VFR, chance of MVFR at KSWF in a rain
and/or snow shower. W/SW 10-15 G20kt.
Tuesday: Chance of a rain and/or snow shower. MVFR, possibly
IFR, especially in any snow showers. WNW G20-25kt in the
afternoon.
Wednesday through Friday: VFR.

&&
.MARINE...
With winds, gusts, and seas expected to increase tonight,
especially late tonight, have begun the Storm Warning for all
the forecast waters with the evening issuance. The strongest
winds and gusts will likely continue into Monday morning before
diminishing rather quickly from west to east midday through
Monday afternoon. The highest winds will likely be after 100 AM
through about 1000 AM Monday. Once the Storm Force gusts
diminish there will be a brief period of gale force gusts
before winds diminish to SCA levels Monday evening, wind winds
falling below advisory levels late Monday night, ending by
Tuesday morning. However, very high ocean seas will remain
through Monday night.
An extended period of SCA is expected on the ocean waters
through at least the end of the week as long period swells from
an offshore storm keep waves elevated. Wave heights on the ocean
will range from 8 to 13 ft Tuesday morning will slowly diminish
through Thursday morning to around 5 ft. They then may build
again slowly through the end of the week.
Winds should remain below SCA criteria, except for Tuesday on the
ocean waters as a tight pressure gradient weakens with high pressure
building in.
&&
.HYDROLOGY...
A total of 2 to nearly 5 inches of rainfall is expected through
Monday afternoon, with most of this falling from late tonight through
Monday morning. Locally higher amounts, as much as 5 to 6
inches, are possible across portions of northeastern New Jersey,
into the Lower Hudson Valley, and possibly into portions of
Southwestern Connecticut (Fairfield County). The location of the
highest amounts will be dependent on the track of the low, and
will be more likely on the upslope sides of higher terrain. With
flooding of fast responding streams, possibly reaching moderate
flooding benchmarks, and flooding of poor drainage and urban
areas, and localized to scattered flash flooding becoming more
likely, the Flood Watch remains in effect tonight through Monday
afternoon. A few of the faster responding stream of northeastern
New Jersey may even reach major flooding benchmarks.
Afterwards, no hydrologic impacts expected through next weekend.
&&
.TIDES/COASTAL FLOODING...
Coastal flood warnings continue for southern Queens, southern
and eastern portions of LI and coastal CT, and expanded for NE
NJ as widespread moderate coastal flooding is likely with the
daytime high tide cycle on Monday. This includes the tidally
affected rivers, particularly Hudson and Hackensack rivers,
where the surge is favored to be forced upstream by the strong
southerly flow. There is potential for locally major flood
thresholds to be reached for southern Queens, SW LI and twin
forks, if windshift occurs near or after the time of high tide.
Elsewhere minor to locally moderate coastal flood potential
exists for NE LI and northern portions of NYC.
Peak surge of 3 1/2 to 5 ft will likely be between high tidal
cycles Monday morning. A later timing of windshift closer to the
early Monday afternoon time of high tide will aid potential for
major flood thresholds to be reached or exceeded for the most
vulnerable southern Queens, SW and E LI portions of the area.
This will likely not be evident until the time of high tide is
approaching. Forecast is a blend of 75th percentile of PETSS,
Stevens, and deterministic ESTOFS.
Heavy rainfall and/or runoff coinciding with the Monday
afternoon high tides will exacerbate street and property
flooding issues along the coast and tidally affected rivers.
Along the ocean beachfront, potential exists for 12-16 ft
breakers Sunday overnight into Monday (8-12ft for NYC
beachfront), which combined with elevated water levels, will
likely result in widespread dune erosion and scattered
overwashes.
Finally, minor coastal flooding possible with tonight's high
tide mainly for southern Queens, SW LI and coastal Westchester
and SW CT.
