Synopsis
Hot and dry weather expected through Saturday. A weak cold
front will settle south of the area tonight. This front will
remain nearly stationary south of the area Saturday and
Saturday night. A frontal boundary will be in the vicinity
Sunday morning, and remain in the area Sunday, as high pressure
builds to the north. The high drifts off the northern new
england coast Sunday as a wave of low pressure moves eastward
along to the boundary into Tuesday. High pressure will follow
late Tuesday and Wednesday. Another wave of low pressure follows
for Wednesday night into Friday through Thursday. A cold front
will approach Friday.

Near term until 6 am Saturday morning
Fast zonal westerly flow in the mid levels will help push a weak
cold front to south of long island late tonight into early
Saturday.

The front appears to have a lack of moisture associated with it.

Models are not displaying much of any QPF with it as it moves
across late tonight. Much of the atmosphere above 5kft will have
a dry westerly flow so just expecting a brief increase in
clouds with the front.

Winds will become light and variable tonight. Lows will be on
the warmer side with the clouds increasing, mid 60s in rural
locations to upper 70s in the nyc urban heat island.

Short term 6 am Saturday morning through Saturday night
Fast zonal westerly flow aloft will remain Saturday and Saturday
night. The heights will be lowering slightly overall during this
timeframe. At the surface, the front will become stationary
south of long island. A shortwave aloft will help with
development of low pressure along the front that will move in
Saturday night into early Sunday.

Another hot dry day is expected with a little more humidity as
well, pertaining to absolute humidity here as diagnosed from
slightly higher dewpoints. A weaker pressure gradient will
result in lighter winds during the day, giving way to typical
sea breeze circulations. The nyc metro area is still going to
initialize Saturday with relatively warmer temperatures.

Therefore, taking this into account, heat advisory criteria is
expected to be nearly met for the greater nyc metro area
encompassing adjacent zones in northeast nj. Cannot rule out
some 95 degree heat indices within the aforementioned area but
majority of heat indices probably in the 91 to 94 range.

For Saturday night, the weather becomes more unsettled with the
increasing chances for showers and thunderstorms. However, the
more recent model trends show a southward trend to showers and
thunderstorms with the wave of low pressure along the front.

Omega increases substantially at 700mb providing extra lift
despite marginal instability. A more southward shift so that
the highest chances Saturday night are along the southern coasts
of the forecast region and nyc. High precipitable waters will
be present so heavy rain will be possible with some
thunderstorms. In addition, gusty winds are possible with some
thunderstorms depending on the strength of the wave of low
pressure. Lows taken from warmer guidance of gmos and mav,
ranging from the upper 60s to mid 70s.

Long term Sunday through Friday
There remains some uncertainty as to the track of an ongoing
convective complex at the beginning of the forecast period, that
will be moving out of the upper midwest. At this time the trend
has been for high pressure to be building to the north pushing a
frontal boundary farther to the south. As a result the forecast
of the complex is also farther to the south Sunday morning. So
have lowered the probabilities overall Sunday, with the lowest
chances to the north. If the high pushes farther to the south
the area may be dry through Sunday.

Then a shortwave will be moving through the northern stream,
across the great lakes Sunday into Sunday night, and the move
slowly through the northeast Monday into early Tuesday as
ridging builds over the western atlantic. Again there remains
some uncertainty with the timing of this shortwave. Also there
is uncertainty as to how much destabilization will occur Sunday.

With an easterly flow developing as the surface high builds to
the north, the area will become more stable under a marine
influence. So while there will be marginal destabilization and will
keep mention of thunder, and with the timing more Sunday night into
Monday, there is more uncertainty with the development of severe
weather with these storms.

Weak ridging will build to the west later Tuesday into Wednesday
as high pressure builds to the west. The upper flow becomes
progressive Wednesday as the western atlantic ridge weakens and
drifts east. Yet another shortwave and cold front will affect
the area Wednesday night into Friday.

Aviation 20z Friday through Wednesday
Surface trough will reside in close proximity to the terminals
today before passing offshore late tonight. Weak high pressure
follows for Saturday morning with a warm front approaching from
the SW in the afternoon.

Vfr through the period. W-nw winds early this afternoon
gradually back around to a more w-sw direction at around 10 kt
with occasional gusts 15-17 kt. Local seabreeze influences at
kjfk, kgon, kisp, and kbdr will allow for some variability
around a SW direction. Light northerly flow develops late
tonight behind the surface trough.
