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
High pressure will dominate the weather through Saturday. A
backdoor cold front pushes across the area Saturday night into
Sunday morning, becoming nearly stationary just south and west
of the area through memorial day. Another cold front follows on
Tuesday with high pressure building in behind.

Near term until 6 pm this evening
Minor changes to forecast based on latest observations.

Heights will gradually rise today as a longwave trough to the
east shifts further into the northern atlantic and ridging to
the west builds.

Sfc high pressure builds from the west today with just some thin
cirrus and perhaps a few CU this aftn from convergence along
seabreeze boundaries. Highs will range from mid 70s to around
80 across much of the tri-state area. Lower 80s are expected in
metro ny nj.

Short term 6 pm this evening through Friday night
Upper level ridging over the great lakes will flatten through
fri night as it traverses eastward as a result of vortexes
remaining over the labrador sea and northern greenland and a
shortwave trough over the western canadian provinces tracking
east.

At the sfc, a return flow develops tonight as high pres shifts
off the new england mid atlantic coasts and continues slowly
into the western atlantic through Fri night. This will result
in an increasingly warm and humid airmass. Expect mostly clear
skies with just some cirrus and perhaps a few CU Fri aftn early
eve. There is also the potential for stratus mainly Fri night
(2nd night of southerly flow) across eastern LI and SE ct. Have
hinted at this in the forecast with partly cloudy skies
developing Fri night. Patchy fog is also a possibility mainly in
rural areas both tonight and Fri night.

Long term Saturday through Wednesday
A broad upper level ridge across the southern two thirds of the
country will get suppressed a bit south through early next week
as a short wave trough progresses across the great lakes and
northeast states. Model differences exist with the magnitude of
the latter feature, which sends a weak cold front across the
region Tuesday. In the case of the gfs, the boundary more or
less washes out as frontal wave passes to the south.

The better agreement though comes with sending a backdoor cold
front across the region Saturday night into Sunday morning,
putting an end to a string of days well above normal. Showers
and thunderstorms are also seeming more likely Saturday night
into Sunday morning as the front interacts with modest
instability, but a weakly sheared environment.

Showers will likely linger into Sunday, but chances should
diminish as high pressure builds southward across new england.

Sufficient overrunning ahead of the approaching upper trough
will be worthy of keeping the mention of showers in through
memorial day. There could even be some scattered thunderstorms
Sunday afternoon west of nyc, depending on how far to the south
and west the boundary stalls.

Additionally, with an easterly flow, temperatures continue to
trend down Sunday and Monday. It may be a bit more tricky Monday
with breaks in the cloud cover as the high weakens, especially
for locations across the interior.

Warmer weather then returns for the Tuesday through Wednesday
timeframe as high pressure builds both aloft and at the surface.

Aviation 12z Thursday through Monday
High pressure builds over the region today.

Vfr conditions are expected through the TAF period, however there's
a low to moderate chance that ifr stratus shifts into kgon this
afternoon and a low chance that it then spreads into kisp kbdr this
evening.

Nnw winds this morning will shift around to local seabreezes in the
afternoon, except kswf. Speeds around 10 kt.
