Synopsis
High pressure over the region moves offshore today and tonight.

A cold front approaches from the west Tuesday and passes through
Tuesday night into Wednesday morning. High pressure then builds
in thereafter through the end of the week with a much drier and
cooler airmass.

Near term until 6 pm this evening
Forecast still mainly on track with just slight adjustments to
temperatures and dewpoints to better match observed trends.

Weak quasi-zonal flow aloft with main upper level jet stream
well northwest of the region. Surface high remains over the
area.

Expecting a mainly dry day with just a slight chance of showers
and thunderstorms for far western orange county late this
afternoon. 850mb temperatures forecast to reach near 15-16
degrees c. Surface temperatures forecast to reach several
degrees warmer than yesterday. Mid 80s to near 90 degrees f for
much of the region with mostly sunny conditions for most
locations.

For sky cover, better chances of having some translucent cirrus
during the timeframe of the partial solar eclipse, which runs
about 120 pm to 400 pm in nyc with a peak at 244 pm, are north
of the city. For long island, the city and adjacent areas of ne
nj, some cirrus still expected but probably not as much
coverage as farther north. Cumulus development is happening
along sea breeze boundaries over long island and ct and slowly
pushing north. Cumulus development may still occur over other
parts of the tri state area, however in almost all cases it
should be no more that scattered.

The western edge of a cirrus shield should be east
of the forks region and SE ct by 200 pm. Another area of
translucent cirrus moving through northern pa would appear to
shift through primarily north of the city in the t cirrus may
however develop and pass through the city and long island during
this period as well, especially if any convection pops up to
our west. Hrrr indicates this convective potential, but may
happen too late to be of much significance. Finally, some
cumulus development along sea breezes this afternoon may cause
some obstruction within about 10 miles of south-facing coasts.

Thinking is that any cumulus would be no more that scattered in
nature for most spots that see it.

Like previous forecast, a look at the hrrrx conveys a slight
decrease during maximum obscuration of Sun during eclipse, so
adjusted temperature a degree downward at 19z (3pm local time).

There is a low risk of rip currents today, becoming moderate
late today at atlantic beaches.

Short term 6 pm this evening through 6 pm Tuesday
Rest of the forecast shows high pressure moving farther offshore
and a cold front gradually approaching from the west. Upper
levels convey an upper level trough with its upper level low based
in ontario approaching the region. Continually more warm and
humid conditions are expected. Forecast has warmer temperatures
Tuesday, getting hot and humid for quite a few locations. Could
see heat indices up to 100 degrees in and around nyc.

Precip forecast remains near or below 30 percent for showers and
thunderstorms. Not much forcing but increasing instability and
possible lee trough forming Tuesday could provide focus for
convergence. Models are pretty minimal with forecast rainfall
amounts overall tonight through Tuesday. Weak trough evident in
lower levels late tonight into early Tuesday will lead to pops
more in low end chance for showers and thunderstorms and then
expecting much of Tuesday to be dry except for interior
locations which will have relatively higher chances for showers
and thunderstorms. These locations will be closer to lee trough
as well.

Long term Tuesday night through Sunday
A cold front approaches the region Tuesday night and pushes across
the forecast area on Wednesday. Expect cloud cover to increase and
showers and thunderstorms to develop and move across the region
through this time frame. By Wednesday evening, skies will begin to
clear and a much cooler airmass will be arriving.

Canadian high pressure builds into the region Thursday through the
weekend, providing dry and sunny conditions. Temperatures will
remain below normal as highs only reach the 70s to near 80 each day.

The dry and cooler conditions are expected to continue into
Monday.

Aviation 18z Monday through Saturday
Vfr through the TAF period as high pressure remains in control.

An isolated shower or TSTM possible late day near kswf, and
early evening for khpn and the nyc metros. Given earlier
upstream activity over western ny, which has died down but
should refire this afternoon, have enough confidence to mention
vcts at kswf.

Sea breezes are in at kbdr kgon, and while direction at most
other terminals continues to vary between SW and w. A more s-sw
sea breeze should set in this afternoon at kjfk kisp and reach
klga late, and kewr kteb could be on the edge of a harbor breeze
late as well. Gusts 15-18 kt likely.

S-sw winds diminish to less than 10 kt this evening.

There is also low potential for development of low clouds fog
late tonight with MVFR or lower flight cat, mainly at
kjfk kisp kgon.

Ny metro enhanced aviation weather support...
