.SYNOPSIS...
-- Changed Discussion --
Partly to mostly sunny conditions will continue
this afternoon before a weak disturbance brings a shower or two to
portions of the area tonight. Warm weather continues on Monday and
Tuesday with isolated showers and thunderstorms possible each day,
mainly across the higher terrain. Rain chances increase mid to late
week as a larger system and cold front approach from the west.

.NEAR TERM /THROUGH TONIGHT/...
-- Changed Discussion --
.UPDATE...As of 149 PM EDT...Pleasant weather to close the
weekend for eastern NY and western New England as a mid and
upper level ridges axis remains over w-central New England. High
pressure is building in from southeast Quebec. Mid and high
clouds are streaming in from the west to southwest ahead a weak
warm front and a short- wave trough running into the ridge from
the Great Lakes Region and OH Valley. Some minor adjustments to
sky cover and temps for partly to mostly sunny conditions. The
12 KALY sounding is very dry in the low to mid levels and had a
PWAT below normal for June at 0.37". The upstream disturbance is
going to run into this dry air mass tonight with some spotty to
isolated showers or sprinkles. Temps will run above normal by
close to 10 degrees with comfortable humidity levels. Max temps
will be in the lower to spotty mid 80s in the lower elevations
and 70s to around 80F over the hills and mtns.

PREV DISCUSSION [0650 AM EDT]...

While the upper- level shortwave will weaken as it moves across
our area later this afternoon and through tonight, enough
moisture may remain for a shower or two to occur, mainly across
western and southern areas. Any showers that do occur should be
very light and not amount to much if anything. Otherwise, skies
will trend mostly cloudy for the night with temperatures
falling into the 50s to lower 60s.

.SHORT TERM /MONDAY THROUGH TUESDAY NIGHT/...
Upper level ridging will reestablish itself near our region
early in the week with it cresting just to our west. We will be
located within north to northwesterly flow aloft as some weak
upper level energy tracks up and over the ridge. Warm conditions
will continue with humidity levels increasing slightly each
day as low level flow turns more southerly with an area of high
pressure setting up to our east near eastern New England.
Enough instability should develop each afternoon for some
isolated to widely scattered showers and thunderstorms. Coverage
looks very sparse on Monday so PoPs were kept below slight
chance at this time. Slightly greater coverage is expected for
Tuesday so included slight chance PoPs and isolated coverage
wording. Most of the activity should favor the higher
elevations. Highs will reach the 80s in the valleys each day
with mid to upper 70s across the higher elevations.

A warm front ahead of our late week system could result in some
lingering showers across western areas Tuesday night. Lows will
fall into the mid-50s to lower 60s.

&&

.LONG TERM /WEDNESDAY THROUGH SATURDAY/...
After a nice stretch of dry weather, the long term forecast
period will feature a fairly wet pattern as a result of a
large-scale, upper-level disturbance...

Wednesday should begin dry for many, outside a few isolated to
scattered showers north and west of Albany, with weak upper
ridging and adjacent surface high pressure remaining in control.
However, shower chances increase across eastern New York and
western New England throughout the day Wednesday as the
aforementioned ridge weakens and shifts east and an upper-level,
closed low pressure system settles across the border of
Manitoba and Ontario. Narrow, negatively-tilted troughing
extending south and east through the Ohio Valley and Great Lakes
will abut the back side of the eastward- propagating ridge to
create a southwest to northeast moisture axis from the Gulf of
Mexico, increasing environmental moisture across the region.
Rain will gradually spread into the region from west- southwest
to east-northeast by late Wednesday morning/early Wednesday
afternoon as the upper low drifts south and east toward to upper
Midwest.

Broad cyclonic flow will remain in place through the remainder
of the extended forecast period as the low slowly slides south
and east into the Great Lakes by Saturday. Multiple rounds of
showers and possibly some thunderstorms will result from its
influence across the region with the best chance for widespread
rain likely spanning Wednesday night through Thursday. At this
time, there is still some uncertainty in the extent and strength
of any resultant thunderstorms throughout the end of the week
and into the weekend due to uncertainty in amount of instability
present across the region. Will continue to monitor the
convective potential throughout the coming days.

Wednesday will likely be the warmest day of the long term period
with highs anticipated in the mid 70s to low 80s. Thursday
through Saturday, highs will generally be in the mid/upper 60s
to mid/upper 70s with pockets of low 60s possible above 1500 ft.
Low temperatures will begin in the mid/upper 50s to low 60s
Wednesday night and Thursday night, falling to widespread 50s
Friday night and Saturday night.

.AVIATION /18Z SUNDAY THROUGH FRIDAY/...
-- Changed Discussion --
Flying conditions are currently VFR across the region with sct-bkn
cirrus clouds and light south to southeast winds.  Through the rest
of the afternoon and into the evening hours, flying conditions will
remain VFR.  Mid and high level clouds will continue to increase
across the area as a weak disturbance approaches from the west.  A
few showers may try to spread towards the area this evening, but low
levels are very dry, so won`t mention any precip in the TAFs at this
time, as any precip will be very spotty and very light.  As a
result, flying conditions should stay VFR into tonight with bkn cigs
around 7-12 kft.  Light south to southwest winds will eventually go
calm or switch to the northwest by late in the overnight at light
speeds.

On Monday, flying conditions will be VFR once again.  Mid and high
level clouds will decrease during the morning hours, with most sites
only seeing sct cigs around 10-12 kft by the late morning hours.
Light north to northwest winds at 5 kts or less are expected through
much of the day.

Outlook...

Monday Night: No Operational Impact. NO SIG WX.
Tuesday: Low Operational Impact. NO SIG WX.
Tuesday Night: No Operational Impact. NO SIG WX.
Wednesday: Low Operational Impact. Slight Chance of SHRA...TSRA.
Wednesday Night: Moderate Operational Impact. Chance of SHRA...TSRA.
Thursday: High Operational Impact. Likely SHRA...TSRA.
Thursday Night: Moderate Operational Impact. Chance of SHRA...TSRA.
Friday: Moderate Operational Impact. Chance of SHRA.
