AREA FORECAST DISCUSSION
National Weather Service Albany NY
109 AM EDT Sun Aug 3 2025

.SYNOPSIS...
High pressure dominating the region will yield a
prolonged period of dry weather across eastern New York and western
New England. And though temperatures will follow a slight warming
trend through Tuesday, low humidity will maintain comfort. The next
chance for precipitation comes Thursday afternoon with the passage
of a weak boundary, but any showers or possible thunderstorm will be
isolated in nature.

.DISCUSSION...
Ideal conditions for early August continue throughout much of
the next seven days with dominating high pressure and low
humidity maintaining tranquility and comfort. A slight warming
trend in temperatures can be expected through Tuesday as the
broad anticyclone at the surface sustains its strength beneath
amplifying geopotential heights and subsequent increases in
850mb temperatures aloft. Expect highs today in the mid/upper
70s to mid 80s before values rise into the upper 70s to upper
80s Monday and Tuesday.

A weak frontal boundary will slowly approach the region from
southeast Canada beginning Monday, barely reaching the northern
extent of our CWA by early Tuesday morning. As this feature
slows further, becoming practically stationary by Wednesday
morning, ridging aloft and high pressure at the surface
simultaneously amplify, allowing it to essentially become washed
out before making its true progression. With counteracting
subsidence, the primary impact of this boundary will be to aid
in increasing cloud cover across the region in tandem with a
disturbance that will remain well off to our southwest.
Therefore, temperatures will be a bit cooler Wednesday with
values likely to be primarily in the upper 70s to mid 80s.

Clouds will stick around Thursday as a weak wave of low pressure
develops in place of the now washed out boundary and high
pressure begins to shift eastward. An isolated shower or
thunderstorm or two cannot be ruled out Thursday as a result,
but with little in the way of forcing and large scale subsidence
sticking around, even this is a low probability at this time.
One more day of "cooler" temperatures is therefore expected
Thursday with highs in the mid 70s to low 80s before another
slight warming trend begins Friday into the weekend. More dry
weather can be expected to couple with these warming
temperatures as ridging aloft amplifies once again with surface
high pressure remaining adjacent. Highs Friday will be in the
mid/upper 70s to mid 80s with values Saturday rising to the
upper 70s to upper 80s. Lows throughout the next seven days will
begin in the upper 40s to near 60 before rising to the upper 50s
to low 60s beginning Monday night.

.AVIATION /04Z SUNDAY THROUGH THURSDAY/...
Through 06z Monday...Mainly clear skies will persist with calm winds
resulting efficient cooling and potential fog formation at
KGFL/KPSF. Mitigating factor is dry air mass in place, which should
limit fog to brief/occasional instances. Will mention prevailing
MVFR vsby at KGFL/KPSF starting at 08z, with TEMPO from 08z-10z for
IFR conditions associated with patchy fog. Otherwise, there could
be a few brief periods of MVFR vsby at KPOU through early this
morning, but VFR should generally prevail especially at KALB. Once
any fog dissipates by 11z-12z, VFR conditions will return. Will
mention 6SM vsby for haze at KGFL/KALB after 12z due to some smoke
drifting south/east from Canadian wildfires. Guidance not indicating
any lower vsby at this time. Winds will initially be calm, becoming
west-southwest around 3-7 kt by this afternoon.


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