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 cold front approach today and pass
tonight. High pressure builds down from southern canada through
Monday night. A coastal low tracks to the southeast of long
island from Tuesday through Wednesday night. High pressure
builds down from central canada for the remainder of next week.

Near term until 6 pm this evening
Upper shortwave passes from NW to SE across new england.

Generally sunny skies and chilly temperatures are expected as
cooler air moved in behind earlier cold front.

Followed a MOS blend, expecting highs from the upper 30s to the
lower 40s.

A few gusts are possible during the day today adding to the

Short term 6 pm this evening through Monday night
Another upper level shortwave passes just to the north tonight
as a weak area of low pressure and frontal boundary move through
overnight. Very low probability for a few flurries, with
operational GFS only model hinting at a few flurries.

Mostly clear skies give way to partly cloudy conditions as these
weak disturbances move through.

High pressure builds from the north Monday, but remains centered
in canada as it is blocked by mid west shortwave tracking from
west to east. During this time frame, mainly clear skies are
forecast, along with chilly temperatures as cold canadian air

Lows each night range from the upper teens to the lower 30s in
nyc. During the day Monday, MOS consensus forecasts a range from
the upper 30s to middle 40s, which seems reasonable given cold
temps aloft.

Long term Tuesday through Saturday
There are 4 main players that will impact how the weather will
play out over the region from Monday into Thursday: 1) the
rather large cutoff low currently over SE canada 2) the cutoff
low currently over the pacific NW (including the lobe that
stretches offshore and is not fully sampled by the radiosonde
network) 3) the ridging between the two systems and 4) the
cutoff low currently over the gulf of alaska.

The models have come into better general agreement in the
evolution of the first feature, maintaining it to the N through
Monday, then lifting it to the NE into the middle of the week -
with some question if another cutoff low replaces the initial
one over SE quebec. They still differ over the handling of the
pac NW system - both in terms of how many pieces of energy break
off from it and head east from the rockies and how rapidly they
do so. Because of the differences in the timing amount strength
of energy ejecting from the pac NW cutoff there are differences
in the ridging between the two cutoff lows. The models are
fairly similar in handling the gulf of alaska system, bringing
it S and serving as an anchor of sorts for the pac NW cutoff as
it eventually opens into a trough by midweek.

The GFS has an additional issue in that its initial coastal low
ends up S of the 700 and 500 hpa shortwave trough that supports
it. This rarely happens - so suspect the surface low is probably
a bit farther N E of where the GFS has it from Tuesday afternoon
into Wednesday.

Given the spread in model solutions have opted to go with a
blend of the 12z ECMWF cmc nam GFS (with surface low and precip
shield modified accordingly based on above). So expect a coastal
low to track to the south then southeast of long island from
Tuesday through Wednesday night (possibly 2 lows depending on
exact evolution of ejecting pac NW energy).

As a result, increase pops on Tuesday to slight chance over
mainly lower hudson valley and SW ct and low end chance
elsewhere, and continue with pops like this through Wednesday
night. With a shift in the average low track farther s, did make
the area mainly snow for this event (consistent with using
surface wetbulb temperature as a rough proxy for the rain snow
line this far out). For now it appears that any coastal low
should be to far SE E on Thursday to have any impact on the
region in terms of precipitation, so have gone dry on Thursday.

One thing that is fairly consistent regardless of solution is
that it will be at least breezy to windy over the region from
late Tuesday into Thursday - potentially rather gusty depending
on exact track strength of the coastal low(s).

The axis of the SE canada cutoff passes to the east Thursday
night, but with dry low levels, it should be dry. Friday and
Friday night should be dry as northern stream ridging transits
the area.

For now went dry on Saturday as a cutoff low builds to the north
but it appears (other than in 12z ecmwf) that the next batch of
moisture lift holds off until later in the weekend.

Temperatures are forecast to be below normal Monday-Saturday.

Aviation 07z Sunday through Thursday
A weak cold front trough has pushed S of all terminals. High
pressure will build to the north today with a weak wave of low
pressure forecast to pass to the SW of the area late.

Vfr and dry weather thru the period.

Nw winds increase 10-15 kt. There may be an occasional gust up
to 20 kt generally between 15z and 22z.

Outlook for 00z Monday through Thursday
Sunday night-Monday night Vfr.

Tuesday Vfr, with a low chance of MVFR or lower by the
afternoon in snow, or wintry mix along the coast. Gusty NE flow
develops, 15-25kt.

Tuesday night and Wednesday Low chance of MVFR or ifr
in snow. Gusty NE wind 15-25kt.

Thursday Vfr. Gusty N wind 10-20kt.

Earlier SCA has expired. Winds should increase by this afternoon
as the pressure gradient tightens, with gusts up to 25 kt
possible over the eastern waters. Will hold off on any headlines
as 25 kt gusts should be brief, late afternoon. However, a short
fused SCA is not out of the question if conditions look to be of
longer duration.

Winds do diminish tonight and into Monday as high pressure
builds in from the north.

Seas remain 4 ft or less on the ocean and 2 ft or less on non
ocean waters through Monday night. However, cannot completely
rule out 5 footers over the eastern ocean waters late in the day
due to an increase in northerly winds.

The pressure gradient should tighten Tuesday and remain
moderate to strong in strength into Thursday. SCA conditions
probably develop on the coastal ocean waters Tuesday and on the
remainder of the waters Tuesday night. SCA conditions probably
will continue into at least Wednesday night, with gale
conditions possible, most likely on coastal ocean waters,
Tuesday night and Wednesday. Conditions should gradually fall
below SCA levels on Thursday.

It should be dry through Monday night.

A low probability for significant precipitation exists Tuesday
through Wednesday night depending on the eventual track of low
pressure centers. If precipitation does indeed occur, it likely
will be in the form of snow, so no hydrologic impacts are

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 during this time, 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.

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