What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

Synopsis
Low pressure riding along a stalled frontal boundary tracks
just south of the region tonight. This low exits to the east
Thursday morning with weak high pressure building over the
region. High pressure retreats to the north and east on Friday
as the next frontal system approaches. This frontal system will
move across the region this weekend. High pressure returns for
next week.

Near term until 6 am this morning
The 00z NAM is panning out with pcpn blossoming over the cwa.

The fcst has been adjusted with the highest rainfall axis
shifted further n. No other changes.

A weak upper level shortwave will move across the region
tonight, with low pressure tracking just south of the region
overnight. LLJ forcing, higher pwats (around 2"), and weak
instability will be close enough to present a quick period of
moderate to heavy rain.

Refer to the hydrology section of the afd for details on
expected rainfall amounts and any impacts.

Lows tonight fall into the 60s.

Short term 6 am this morning through 6 pm Friday
Any precipitation comes to an end Thursday morning, with high
pressure building in from the west. Drier conditions can then
be expected for the remainder of the day. Slowly clearing skies
will lead to partly to mostly sunny day. Daytime highs climb
into the 70s and 80s.

Fair conditions continue Thursday night as high pressure
continues to build into the region. Overnight lows will fall
into the 50s and 60s. A mav met ecs blend was in good agreement
and used for temperatures in the short term.

Long term Friday night through Wednesday
The main forecast challenge in the long term revolves around a
frontal system progged to impact the local area this weekend.

The frontal system will be in association with an upper low
than opens up as it lifts into the great lakes region. Ensemble
means and deterministic runs overall agree on the synoptic
evolution this weekend, but there are differences in timing and
amplitude of shortwaves within the upper low trough.

Upper ridging will be in place on Friday and the best forcing
will be located well to the south and west. The upper ridge axis
generally remains in place Friday night as the shortwave
approaches. At the surface, a warm front will approach from the
south enhancing low level warm advection. One of the biggest
uncertainties heading into Saturday revolves around how much
surface ridging lingers from the high pressure to the northeast.

The low level easterly flow may serve to enhance the surface
ridging, keeping subsidence and stable conditions across the
region. This may slow the progress of the warm front a bit as
well. At the same time, the upper low and trough are progged to
open up and broaden as the system lifts towards the great lakes.

The main upper trough axis swings through Saturday evening and
Saturday night leaving behind a westerly flow on Sunday. Another
upper trough should cross the region Sunday night into Monday,
finally taking the frontal system offshore.

For sensible weather, dry conditions are forecast on Friday
with gradually increasing pops on Friday night into Saturday
morning. The ECMWF appears quickest to break the surface ridging
with the warm front moving across much quicker than the gfs.

Have gone with a slower progression with likely pops spreading
across the area late Saturday morning into the afternoon. It
appears at this time the best forcing will be with the upper
shortwave axis and passage of the warm front Saturday evening
into Saturday night. Little to no instability is present on
model soundings during the day Saturday, so have removed mention
of thunder until Saturday evening and night. Conditions should
dry out Sunday with the region fully in the warm sector.

Westerly flow aloft and a much drier middle and upper
atmosphere prevents anything more than a chance for showers and
thunderstorms with a cold front nearby. The chance for showers
and thunderstorms continues into at least Monday morning with
the upper trough axis passing across. If the timing of the upper
trough is slower, pops may need to be increased on Monday.

While the weekend does not look like a washout, there will be
periods of showers and possible storms Saturday night into
Sunday. Locally heavy rainfall is possible in any convection.

High pressure returns behind the upper trough and frontal
system moving offshore on Monday. The high will be in control
through the middle of the week.

Temperatures average below normal Friday and Saturday and then
above normal on Sunday. Temperatures should then average near
normal for next week.

Aviation 06z Thursday through Monday
A wave of low pressure approaches from western pennsylvania,
passing near or just south of the terminals during the overnight
hours. A backdoor cold front moves into the terminals toward
00z Friday.

MVFR conditions in rain expected through the early morning
hours. Periods of ifr conditions are possible in any heavier
pockets of rain, primarily across the nyc and coastal terminals.

Rain then tapers off from west to east between 09z and 12z, with
conditions improving toVFR thereafter.

Light and variable winds overnight return out of the N to ne
around daybreak as the low passes to the south and east. NE to
at times E winds then continue through the day at around 10 kt
before diminishing tonight.

Outlook for 06z Friday through Monday
Thursday night and Friday Vfr.

Saturday Sub-vfr. Showers likely, possibly a thunderstorm
during the evening and nighttime hours.

Sunday Chance of sub-vfr conditions in showers and
thunderstorms.

Monday Chance of showers early, becomingVFR.

Marine
Sub-sca conditions are expected on the area waters as a relaxed
pressure gradient remains over the area waters.

Winds will remain 10 kt or less through Thursday night. The
possible exception is over the coastal ocean waters west of
moriches inlet, where sustained winds up to around 15 kt are
possible.

Winds and seas will stay below SCA levels on Friday. A frontal
system impacting the waters this weekend may bring winds to around
20 kt on the ocean with seas gradually building as well. Seas may
build to 5 ft on the ocean on Sunday as a warm front moves north and
sw flow increases further.

Hydrology
A generally 1 2 to 1 inch of basin average rainfall can be
expected into this morning. Amounts may be less across the swrn
portion of the cwa.

Locally heavy rainfall is possible this weekend, especially late
Saturday into Saturday night. However, no significant widespread
hydrologic impacts are currently expected.

Equipment
Nyc NOAA weather radio station kwo-35 (162.55 mhz) remains off
the air for an extended period of time.
