What's New / NOTES
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.
6/25/2017 - NOAA is having a major issue that impact the 7 day forecast load times. Many users are reporting problems. The issue has been reported.
5/23/2017 - Worked with NOAA again to speed up the 7 day forecast load times. Thanks to them for being responsive.

Weak low pressure and a cold front move across the region
tonight. High pressure builds down from southern canada Monday
and Monday night. A couple of coastal lows track from off the
mid-atlantic coast into the canadian maritime provinces from
Tuesday into Thursday night. High pressure then builds down from
southern canada from Friday through Saturday. A storm system
tracks from the ohio river valley to the mid atlantic states
Saturday night, then to the south of long island on Sunday.

Near term until 6 am Monday morning
A weak surface low moving into the eastern great lakes will
continue to track southeast and move through tonight. There is
little mid level and upper level support with the surface low,
as weak energy rotates through the western portion of the upper
trough. Low levels will remain dry, however, models do indicate
the possibility of light snow as the low tracks across the
region. So will continue with the chance of flurries. A weak
cold front or surface trough accompanies the weak low.

Short term 6 am Monday morning through Monday night
The upper trough remains across eastern canada and the northeast
Monday and Monday night, meanwhile a ridge remains to the west.

The mid and upper level systems remain blocked while a surface
high builds in from southern canada through the period.

Long term Tuesday through Sunday
Two storm systems could impact the area from Tuesday-Sunday.

The first storm system will come in two waves, the first in
response to shearing energy emerging a cutoff low over the
rockies that tracks to the south of long island Tuesday. At this
time it appears any precipitation from this first bit of energy
should be relatively light and based on a blended thermal
profile and surface wetbulb temperatures, should fall as mainly
snow. However, given sun-angle, would expect any accumulation to
be limited to mainly grassy surfaces. Generally less than 1 inch
of snow is expected during the day on Tuesday, mainly across
nyc long island southern portions of NE nj. There is generally
good agreement among the models with this idea with solid
support from the cmc ECMWF sref and the nam GFS just offshore
(but also with a more sheared out solution to the shortwave than
the others, so adjusting for this, you have a reasonable

The second wave with the first storm is in response to a
combination of the remainder of the energy associated with the
initial closed low over the rockies and a second piece of energy
that comes down from SW canada (which at one point was also part
of the rockies cutoff). This helps to carve out a larger low-mid
level shortwave trough potential 700 hpa closed low - and hence
a stronger coastal low that tracks to the S E of the 40n 70w
bench mark. There is also a general consensus for this idea from
the models in a general sense. However, with the nam GFS likely
too far S E with initial low, their path for the follow-on low
likely also is too far to the S e, so followed a SREF cmc ecmwf
blend with the second low.

So expect another round of snow to develop later Tuesday night
and linger into Wednesday night. Once again thermal profiles and
surface wetbulb temperatures support mainly if not all snow.

Still some question of how much and how far to the NW QPF falls
with this storm. There is the potential for advisory level snows
across mainly the southern 1 2 of the cwa. It should be noted
that our snow grids, consistent with duration of wpc produced
snow probabilities only go through 00z Thursday, so do not
capture all of the snow expected to fall from this system. There
is still uncertainty on the exact strength, timing and track of
the storm, so would expect refinements to the forecast with
time. Currently the range of solutions range from no snow to a
very low chance of a low end warning snowfall across far s
portions of the cwa. A mitigating fact to any snow accumulation
will be the Sun angle this time of year, and even with wet
bulbing, could see temperatures near or right above freezing.

With low levels drying behind the storm, even with passage of
trough axis on Thursday Thursday night, it should be dry, except
for maybe some lingering snow early over far eastern parts of
the cwa. Another shortwave pushes through Friday, but once again
the dry low levels should preclude any precipitation.

Shortwave ridging crosses the area Friday night and Saturday, so
it should continue to be dry.

The next storm system comes in response to a northern stream
trough developing closed low moving into the great
lakes southern canada Saturday night and Sunday. At this time
there is the potential for mainly snow across northern portions
and a rain snow mix across the S 1 2 of the cwa.

Temperatures should be below normal Monday-Sunday.

Aviation 20z Sunday through Friday
High pressure will build to the north. A weakening low will
pass across the region tonight.

Vfr through the TAF period. NW winds today around 10kt will gust
to around 20-25kt through about 22z. Gusts then diminish and
winds fall below 10kt, eventually becoming light and variable
overnight. On Monday, winds increase from the north to around
10kt, then become northwest by mid to late morning.

Outlook for 18z Monday through Thursday
Monday afternoon and Monday night Vfr.

Tuesday Low confidence forecast through Wednesday. Chance of
snow with ifr conditions for the long island and nyc metro
terminals. Ene winds g20kt nyc metro coastal terminals.

Tuesday night MVFR conditions possible with any lingering
snow showers. NE winds g20kt nyc metro coastal terminals, mainly

Wednesday Snow with ifr conds likely at the long island
terminals, and may also be possible farther north including all
local terminals. NE winds g20-25kt.

Thursday-Friday Vfr. N winds g15-20kt.

Wind gusts and seas on the ocean waters have diminished.

However, there may be an occasional gust to near 25 kt on the
eastern, outer waters through the remainder of the afternoon.

With wind gusts generally below SCA levels, and seas less then
5 ft, will cancel the SCA for the rest of the afternoon.

A weak flow will be across all the forecast waters tonight as a
weak low moves through, then high pressure builds to the north
Monday into Monday night. Winds and seas will be below sca
levels through Monday night.

Small craft conditions are likely on the coastal ocean waters on
Tuesday with sub-small craft conditions on the non-ocean waters.

The pressure gradient tightens Tuesday night and remains
relatively strong over the region into Wednesday night. As a
result gale conditions are possible Tuesday night-Wednesday
night on the coastal ocean and waters and small craft conditions
are probable on the non-ocean waters during this time frame. The
threat for gales will be highlighted in the hwo.

The pressure gradient then gradually slackens from Thursday
through Friday, with small craft advisory (sca) conditions
lingering on all waters into Thursday and on the coastal ocean
waters into and possibly though Thursday night. For now, it
appears that sub-sca conditions should occur on all waters
Friday and Friday night.

It will be mainly dry through Monday night.

There is the potential for a prolonged period of precipitation
from Tuesday through Wednesday night. At this time, it appears
that total amounts should be less than 1 inch of liquid, and
with it expected to fall mainly, if not all as snow, no
significant hydrologic impacts are expected.

Tides coastal flooding
There is the potential for a prolonged period of e-ne flow from
Monday night into Wednesday night. Tidal departures of
generally only 1 to 1 1 2 ft are needed for minor flooding for
many locations Tuesday night through Wednesday night, and 2 to
3 ft for moderate.

Depending on the exact track strength of a coastal low or lows
during this time frame, there is the potential for minor to
moderate coastal flooding, but predictability on the details
remains low.
