Area Forecast Discussion
National Weather Service New York NY
202 PM EDT Mon Apr 15 2019
.SYNOPSIS...
A cold front moves east of the area this afternoon. High
pressure then builds into the region through Wednesday. A warm
front then slowly approaches from the southwest and moves to the
north Friday morning, followed by a cold frontal passage late
Saturday into Sunday.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
Showers slowly exiting the eastern zones, and updated to keep
higher probabilities into later this afternoon, as the cold
front was slowly moving into eastern Connecticut and eastern
Long Island. The slower movement was also affecting the
temperatures and dew points. Winds were taking a little longer
for the higher gusts to develop, and are expected to be near
advisory levels around 20Z. Then winds may remain strong and
gusty a few hours after sunset.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM TUESDAY/...
Winds will remain strong into tonight, perhaps continuing at
wind advisory strength longer than forecast as strong cold
advection continues behind the departing system. Temperatures
will return to near or slightly below seasonable values, with
wind chills making it feel as though it's only in the upper 20s
to mid 30s.
Skies then remain mostly sunny into Tuesday, with highs near
seasonable values, though with gusty winds continuing.
&&
.LONG TERM /TUESDAY NIGHT THROUGH SUNDAY/...
Upper flow briefly flattens out to start the period with an
upper low departing from the Canadian Maritimes. At the same
time, a trough moves into the desert southwest. Later in the
week, this feature will interact with northern branch energy,
sending a frontal system into the area for the end of the week
into the weekend. There is very good agreement with the 12Z
ECMWF and GFS with the extent of phasing of the two branches and
the progression of the aforementioned frontal system. The GGEM
is a bit more progressive, especially with the lead frontal band
precipitation Friday night into Saturday morning.
A consensus forecast approach brings high pressure into the
region Tuesday night into Wednesday with a warm front
approaching from the southwest.
There is a low chance of rain working in from the southwest
Tuesday night. However, unlike 24 hours ago, it appears
Wednesday will be dry as ridging builds in both aloft and at the
surface. The northward progress of the warm front will likely
be very slow due to an amplified ridge building along the
eastern seaboard as the upper trough amplifies across the mid
section of the country.
Warm frontal passage has trended faster in the global guidance,
lifting north of the region by daybreak Friday. A deep-layered
southerly flow develops along the east coast as the upper ridge
slowly translates east Thursday into Friday. A strong low-level
jet ahead of the approaching cold front supports moderate to
heavy warm conveyor belt rains with embedded thunderstorms late
Friday night into the first half of Saturday. There will likely
be timing changes through the week as the Pac jet energy has yet
to move onshore. Additionally, a strong onshore flow Friday
into Saturday will likely result in areas of stratus and fog,
especially east of the Hudson River. Dew points are forecast to
be in the 50s, but this may be conservative.
Scattered showers may linger into Sunday depending on how
quickly the upper trough/low passes through the area.
As for temperatures, daytime highs will be near seasonable
levels through Thursday before a warm frontal passage Friday
morning. Lows will be several degrees above normal due to
onshore flow and potential for stratus/fog. Following the warm
front, warmer, humid conditions are likely with areas away from
the coast getting into the 70s.
&&
.AVIATION /18Z MONDAY THROUGH SATURDAY/...
A second continues to move across the region. High pressure
will begin to build back into the region tonight.
Showers associated with a second cold front have moves east of
NYC and will clear the eastern most terminals between 19z-20z.
Once the showers end, Winds will become Westerly and increase
with gusts 35-45 kt possible during the afternoon/evening hours.
The highest gusts are expected along the coast.
Winds will begin to diminish after midnight, however wind gusts
between 20-30kt are still expected.

.Friday and Saturday...MVFR or lower possible in shra, iso
tstms. Gusty S winds possible.

.MARINE...
Lowered the wind gusts across the waters until late this
afternoon when colder air pushes into the waters and better
mixing will occur. Gusts will remain at gale force through
tonight and possibly into Tuesday morning across the waters east
of Moriches Inlet, and may be extending the warning into Tuesday
morning.
A gale warning remains in effect, with the strongest winds
expected this evening. Winds diminish Tuesday through Tuesday
night as high pressure builds across the waters. Ocean seas will
also gradually subside in response. Sub- SCA conditions then
continue into Thursday as high pressure remains over the region.
Southerly winds then ramp up Thursday into Friday with SCA
conditions likely developing on the ocean waters Thursday night
and continuing into Friday.
&&
.HYDROLOGY...
The next potential for significant rainfall will be Friday
night into Saturday with a slow moving frontal system.
Minor flooding is possible on the Lower CT River by mid week
due to runoff from recent rainfall events and from upstream snow
melt in VT and NH.
