area forecast discussion

1006 am edt Mon aug 20 2018

Synopsis
High pressure from the canadian maritimes will move slowly
farther northeast through early Tuesday. Low pressure moving
northeast across the upper great lakes into ontario and quebec
will send a warm front toward the area late Tuesday, followed by
a cold frontal passage on Wednesday. High pressure will then
settle over the area late this week and start to weaken late in
the weekend.

Near term until 6 pm this evening
Forecast remains on track with a chance of rain and drizzle
through the day. Previous discussion follows.

An upper level disturbance in the form of a 500mb vorticity
vorticity maximum will be moving slowly northeast of the region
today.

Models are in general agreement with some very light QPF today
along the coast as clouds linger there. The NE flow at around 10
to 20 mph will continue to provide more stable low level flow,
relatively cooler and a little less humid.

A lingering trough axis near the surface and the moisture rich
boundary layer with NE flow will enable some light rain or
drizzle along the coast where there will be a little more
convergence.

Initially mainly dry conditions are anticipated but pops
increase in the afternoon with the high pressure area weakening
and translating farther northeast away from the local region.

High temperatures forecast today are mainly in the mid to upper
70s.

There is a moderate risk of rip currents at the atlantic ocean
beaches for today.

Short term 6 pm this evening through 6 pm Tuesday
A lingering slight chance of light rain or drizzle along the
coast is forecast tonight but without much forcing present,
think this will be brief and pops are below chance (slight
chance). Left late evening and overnight dry going into
Tuesday.

A larger amplitude trough moves closer Tuesday and this will
eventually bring higher pops for showers into the region. A
warm front will approach the region at the surface. Its surface
parent low will move from the great lakes into quebec. Went with
slightly cooler high temperatures compared to the previous day.

Models are not conveying much diurnal instability so left out
thunder.

For Tuesday, the risk for rip currents at atlantic ocean beaches
will be moderate with winds becoming more e-se and easterly
swell.

Long term Tuesday night through Sunday
Low pressure over the great lakes continues to lift northward into
canada. Meanwhile. An upper level trough approaches from the west. A
warm front should be over or just about to move into the region
around the time the long term period starts. As a result, shower
coverage should increase, with a few heavier showers and
thunderstorms possible late Tuesday night. A cold front will then
move across the region on Wednesday at least for nyc metro and
points west, but the front could progress slowly enough to allow for
instability to build over eastern ct long island and spark another
round of showers tstms mainly in the late morning and early
afternoon.

Drier weather is then expected Wednesday night, as high pressure
starts to build into the region. Expect a period seasonably warm and
less humid days coming up for Thursday-Saturday.

The high begins to weaken and slide east Saturday night and Sunday.

Meanwhile, a weak upper level shortwave will pass north of the
region. This may set off a few showers late this weekend.

Aviation 13z Monday through Friday
A weak frontal boundary remains nearly stationary across the
mid atlantic states through today, meanwhile, high pressure
noses in from the north. The high retreats tonight as a warm
front begins to approach from the south. The warm front moves
into the region late Tuesday.

MVFR ceilings this morning across the terminals should
gradually lift toVFR with sct MVFR CIGS this afternoon, but
timing in TAF could be off by 1 to 3 hours on how quickly this
happens. Periods of dz or br possible through the day.

Widespread MVFR conditions expected to re-develop tonight, with
ifr conditions likely for eastern terminals. Again, period
drizzle will be possible, especially Tuesday morning.

Ne winds of 8 to 12 kt, expected to veer to the E this
afternoon, then diminishing tonight.

Ny metro enhanced aviation weather support...

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
