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.

Synopsis
A large... Slow moving storm system moving by to our south tonight
and Wednesday will bring a period of widespread light rainfall to
our region tonight and Wednesday... With lingering showers then
gradually tapering off from west to east Wednesday night and
Thursday as high pressure and drier air builds across the lower
great lakes.

Near term through Wednesday
As of early this evening... Fairly widespread (albeit rather light
rain) has already overspread the region from roughly the genesee
valley westward... With relatively dry conditions still prevailing
further to the east.

As we progress through tonight... The responsible area of low
pressure over the carolinas will continue to pump increasing
amounts of atlantic-based moisture into our region as it heads
toward the mid-atlantic coastline. At the same time... Modest height
falls aloft and a diffluent upper level flow regime (owing to a
weakly coupled upper level jet) will help to lift this deepening
moisture field... Resulting in occasional light rain continuing to
slowly spread northeastward across our region... With the steadier
rain finally reaching the north country toward daybreak. Total
nighttime rainfall amounts will range roughly from up to a couple
tenths of an inch across far western new york to under a tenth of
an inch east of lake ontario... With some patchy fog also developing
overnight as the lower levels moisten. This will especially be the
case across the higher terrain (generally >1500') where the lowering
stratus will intersect the ridge tops.

On Wednesday... The southern stream stacked low will continue east to
the mid atlantic coast while a robust northern stream shortwave will
approach from the upper great lakes. Earlier guidance suggested that
these two features would phase in time to have an influence on our
weather... But it now appears that they will remain two distinct
features until they move east of our region. In any case... The axis
of the mid level trough between the two will cross our region and
help to focus more light to occasionally moderate rain. The amount
of lift is not forecast to be as significant as that from the
overnight... But there will be more moisture to work with. Will
maintain cat pops with daytime rainfall amounts in the vcnty of a
quarter to a half inch... With the higher amounts expected to be near
and east of lake ontario.

Short term Wednesday night through Friday night
On Wednesday night, a closed 500 mb embedded in the northern branch
of the jet will absorb another low across the mid-atlantic states.

Model guidance differs on the track of this with the 12z gem ecmwf
guidance tracking this low across western new york while the NAM gfs
guidance is north and faster with its track. The southerly slower
track would result in more precipitation and have it last a bit
longer. The forecast uses a consensus of guidance with fairly steady
showers Wednesday evening tapering off from west to east overnight.

Consensus 850mb temperatures fall to around 0c which may allow some
wet snow to mix in across the highest terrain in the southern tier
but this will not result in any accumulation. Low temperatures will
range from the mid 30s to lower 40s on Wednesday night.

Showers will likely linger east of lake ontario into Thursday
morning, but the rest of the area should be mainly dry on Thursday
as a ridge of high pressure builds in from michigan. As a result the
forecast is a bit warmer with highs in the 50s with a modest lake
breeze developing in the afternoon. High pressure will then briefly
ridge across the region Thursday night with dry weather and lows in
the 30s.

A broad upper level trough axis will gradually shift to the east
coast Friday and Friday night. A broad surface low is forecast to
develop across the mid-atlantic states on Friday and track into new
england on Friday night. Model guidance differs, but this may clip
especially eastern portions of the CWA on Friday with some light
rain showers possible. Then showers are possible in all areas Friday
night when the upper level trough axis moves across the area.

Rainfall amounts should be fairly light with this, generally under a
quarter inch. Temperatures should be near normal with highs on
Friday in the mid 50s to around 60.

Long term Saturday through Tuesday
Showers will move through the area on Saturday as an upper level
trough drops from the great lakes to the new england coast. With
this trough passage temperatures will also cool to the low to mid
50s for Saturday and Sunday.

Behind the departing upper level trough, a ridge will begin to build
into the region providing warming temperatures and dry conditions
through the middle portion of the week. An area oh high pressure
will build to the south over the ohio valley and southeastern us.

This will allow a southwesterly flow to develop helping to aid in
strong warm air advection resulting in warmer temperatures for the
region. Temperatures will warm to the 60s for Monday and the 70s on
Tuesday. The weather should remain mostly dry through the middle
portion of next week with the influence of this high pressure to
the south of the area.

Aviation 00z Wednesday through Sunday
Vfr conditions will gradually deteriorate from southwest to northeast
tonight as occasional light rain across western new york spreads
across the remainder of the region and the lower levels of the
atmosphere continue to moisten... Resulting in the development of
MVFR to ifr ceilings and eventually some patchy fog. Expect the
worst (ifr) conditions to develop across the higher terrain... With
conditions mainly lowering to MVFR across the lower elevations.

On Wednesday... Widespread MVFR to ifr CIGS will be in place across
the region as light to occasionally moderate rain will continue. The
lowest CIGS will again be found across the higher terrain.

Outlook...

Wednesday night... MVFR to ifr with lingering showers.

Thursday... Improvement toVFR with showers ending.

Friday and Saturday... MainlyVFR with a chance of showers.

Sunday... MainlyVFR with a chance of rain or snow showers east
of lake ontario.

Marine
A relatively weak surface pressure gradient will remain in place
across the lower great lakes through Wednesday... As a large but
poorly organized storm system will pass by well to the south. This
will keep generally light winds and negligible waves in place.

In the wake of this system... Winds will freshen Wednesday night into
Thursday. This could lead to small craft advisory conditions for
sites on lake ontario east of thirty mile point.

Buf watches warnings advisories
Ny... None.

Marine... None.
