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 builds today and Tuesday. The high moves offshore
Wednesday, allowing a warm front to slowly lift northward into
Wednesday evening. A cold front will then gradually move through
the area Thursday into Thursday night, followed by building
high pressure into the weekend.

Near term until 6 pm this evening
Upper trough axis oriented from NE to SW passes across the northeast
today, with PVA passing this afternoon.

Surface low off the new england coast continues to track east. A sfc
trough associated with the passing upper level trough should result
in a wind shift to the E SE over extreme SE ct and eastern LI late
in the day. Otherwise, NW flow behind a cold front persists.

Mostly sunny skies prevail, with mid level instability clouds
developing in the afternoon as the upper trough cold pool passes.

Too dry in the lower levels for any showers, with best chance for a
passing shower just to the east in new england (ri and SE ma).

Temperatures warm to the upper 70s lower 80s. Right around normal.

With no sea breeze (other than late day shift over extreme eastern
portions of the cwa), temps along the coast will be warmer than
yesterday.

There is a moderate risk for rip current development at atlantic
beaches today.

Short term 6 pm this evening through 6 pm Tuesday
Upper ridge builds behind departing trough. Sfc high pressure builds
tonight and passes offshore Tuesday. Light north winds tonight will
eventually shift to the south.

With strong subsidence, mainly clear skies are forecast, and the
clear skies and lightening winds will allow for radiational cooling
to take place tonight. In the normally cooler locations, lows will
fall to around 50, with lower to middle 60s in and around nyc thanks
to heat island effect.

For Tuesday, onshore flow will result in cooler readings, especially
near the coast. Temperatures over eastern LI and SE ct may only
reach 70 degrees, with readings near 80 in nyc and away from the
coast.

Long term Tuesday night through Sunday
Upper ridging and an attendant surface high shift farther offshore
on Wednesday in advance of a weak approaching short wave. A warm
front will move northward through the day, and with broad south-
southwest flow, moisture will rapidly increase, with a noticeable
return to humidity by Wednesday night and pwat values close to
climatological maximums for the time of year. As the short wave
moves into the area overnight, expect shower and thunderstorm
chances to increase overnight Wednesday into Thursday. Despite
modest flow, moist adiabatic lapse rates and weak lapse rates will
generally limit any severe potential, with the predominate threat
locally heavy downpours. The exception may be along the immediate
coast Wednesday night, with warm water temperatures across the new
york harbor into western nassau county and modest SRH shear in the
lowest 3km, weakly rotating storms capable of waterspouts may not be
out of the question. Showers and thunderstorms may continue through
much of the day Thursday as the short wave slowly moves through the
area, coming to an end from west to east by the evening into the
overnight as a cold front moves through, bringing lower humidity
values.

Thereafter the main story becomes heat as a ridge strengthens along
the eastern u.S. By Friday, temperatures will be well above
climatological normals, with values approaching the low to mid 90s
into the weekend to the north and west of nyc, and 80s expected
elsewhere. There are timing differences with regards to any short
wave that will pass to the north of the area, but in general
deterministic guidance tends to be too quick to break down strong
ridges, so maintained a dry forecast beyond Thursday.

Aviation 07z Monday through Friday
A cold front will move across the region tonight. High pressure will
build west of the terminals Monday and Monday night. A surface
trough develops east of the region Monday night.

Generally looking atVFR conditions. Some ifr CIGS have
developed across kswf kbdr kgon. Any lower conditions should be
temporary as drier conditions are expected with the passage of
the cold front.

Winds will shift to the NW behind the front, mainly to the
right of 310 magnetic. Gusts develop early Monday morning with
gusts 20-25 kt. Winds and gusts diminish after 22z Monday. A
surface trough develops east of the terminals late Monday,
resulting in terminals east of nyc to shift more towards the
east.
