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 for the long island waters and new york harbor.. High pressure retreats to the east, as an area of low pressure riding along a stalled frontal boundary tracks from the ohio river valley today to near the mid-atlantic coast by Thursday morning. This low exits to the east on Thursday as a separate cold front pushes to our south, followed by weak high pressure building over the region into Friday. A frontal system will slowly approach the area on Friday, as the high retreats to the northeast, and then impacts the region over the weekend.

Synopsis
High pressure retreats to the east, as an area of low pressure
riding along a stalled frontal boundary tracks from the ohio
river valley today to near the mid-atlantic coast by Thursday
morning. This low exits to the east on Thursday as a separate cold
front pushes to our south, followed by weak high pressure
building over the region into Friday. A frontal system will
slowly approach the area on Friday, as the high retreats to the
northeast, and then impacts the region over the weekend. High
pressure will build in behind the system into next Tuesday.

Near term until 6 pm this evening
Forecast on track with just some minor adjustments to reflect
latest observations. Clouds increase late this afternoon as a
northern stream shortwave approaches from the west. There could
be some stray showers by late afternoon as the shortwave
approaches, mainly across far western zones.

Highs today should be near normal, mainly from the mid 70s to
around 80 across the region.

Short term 6 pm this evening through 6 pm Thursday
A northern stream trough builds into the area tonight, this
coupled with some low level instability (focused mainly over the
southern 1 2 of the cwa) should bring some showers to the
region tonight, and possibly a rumble of thunder as well (mainly
to the southern 1 2 of the cwa). Precipitable waters increase
to from 1.75 to around 2 inches (with values around 2 inches
focused over the southern 1 2 of the cwa), so locally heavy
rainfall is possible, especially in association with any
stronger convection overnight. Refer to the hydrology section
of the afd for details on expected rainfall amounts and any
impacts.

There is some uncertainty on the timing of the showers tonight,
but for now a consensus timing would be for the most numerous
showers and best chance for any locally heavy rainfall to occur
from around 9pm- 5am.

The timing for the end of the rainfall has slowed, with showers
now expected to linger into Thursday morning. The showers
likely should come to an end by mid-late morning, as the axis
of the northern stream trough exits to the east, allowing for a
drying NW flow to set up over the region by afternoon.

Lows tonight and highs on Thursday should be near to slightly
above normal.

Long term Thursday night through Tuesday
The models are in good agreement with the general pattern in the
long term, although some timing and placement issues remain. An
approximately 1020 hi will be set up from the maritimes swwd to cntrl
new england fri. At the same time, SW flow aloft develops as an h5
low spins over the midwest. This will result in increasing thetae
and chcs for shwrs and tstms Fri and particularly Fri ngt. The upr
support arrives Sat and Sat ngt. The GFS is a bit faster than the
ecmwf. Likely pops have been included during the day on Sat based on
a blend of all of the model data. As the upr trof arrives on Sun and
mon, there will be additional chances for pcpn. These appear to be a
bit more diurnally focused, with daytime heating providing the added
instability boost needed. High pres then builds in on Tue and dries
out the area. The nbm was used for temps thru the period.

Aviation 18z Wednesday through Monday
Low pressure approaches from the ohio valley tonight and then
passes near or just south of the terminals Thursday morning.

Vfr this afternoon evening, then MVFR ifr late tonight in
moderate to occasionally heavy rain.VFR conditions return
Thursday morning in the 10 to 13z timeframe.

S winds 5 to 10 kt back around to the NE Thursday morning as the
low passes to the south and east.
