Synopsis
An large upper level trough over the great lakes will provide our
region with cool weather through the end of the work week. A few
spotty light showers will remain possible at times into Friday
morning... Before high pressure brings dry weather from Friday
afternoon right on through the upcoming weekend... Along with a
gradual warming trend.

Near term through tonight
Valley fog across the southern tier will persist through sunrise...

before dissipating by mid morning with renewed daytime heating and
mixing.

Otherwise... Our region will remain firmly locked in the grip of deep
longwave troughing today... With another shortwave (currently over
the upper mississippi valley) quickly diving through the base of the
trough and reaching our region during the late morning and afternoon
hours.

The combination of our cool airmass aloft... Increasing background
moisture... And lake-induced thermal troughing should initially lead
to an expanding area of lake effect clouds and scattered lake effect
showers along and inland from the south shore of lake ontario
through the early to middle portions of this morning. After that
time... Increasing diurnal influences and the approach of the
shortwave will result in the better instability shifting to areas
further inland and the forcing becoming increasingly synoptically-
driven rather than lake-driven... Which will in turn result in the
showers becoming increasingly diurnally-driven and gradually sliding
southeastward across the remainder of western new york. In the
forecast... Have covered these with a mix of low to mid-range chance
pops... Which best fits the expected scattered coverage. Aside from
the showers... We can also expect a fair amount of diurnal cumulus to
develop with diurnal heating of our cool airmass today... Which
should result in predominantly partly sunny skies during the late
morning and afternoon hours. As for temperatures... 850 mb readings
will generally be between +6c and +8c... Which should translate into
afternoon high temps mostly in the mid to upper 60s... With just a
few of our normal warm spots possibly reaching the 70 degree mark.

Such temperatures will be a solid 10 degrees or so below normal late
august levels... And will in fact be more typical of those of mid to
late september.

As we move on into tonight... The loss of diurnal influences will
result in the scattered diurnally-driven showers transitioning back
to some more isolated to widely scattered lake effect showers along
and a little inland from the south shores of lakes erie and
ontario... With the latter likely remaining rather limited in extent
due to the weak and somewhat sheared northerly low level flow that
will be in place. With this in mid... Have kept precipitation chances
for tonight confined to the slight chance to low chance range.

Otherwise conditions will be largely dry... With some partial
clearing also eventually allowing for the development of another
round of southern tier valley fog by later on tonight. With our cool
airmass remaining in place... It will be another cool and comfortable
night for sleeping... With overnight lows ranging from the mid to
upper 40s in interior portions of the southern tier and north
country to the lower to mid 50s along the lakeshores.

Short term Friday through Saturday night
Plenty of over-lake instability still in place Friday as
unseasonably cool 850 mb temperatures of around 5c remain over the
lower great lakes. Relatively short northerly fetch and incoming
drier air should keep lake induced rain showers limited on Friday.

Any early day showers and clouds will give way to at least partial
sunshine by mid day or early afternoon, as drying continues and lake
processes become diurnally disrupted. 850 mb thermal trough
positioned across the lower great lakes Friday will result in
another unusually cool august day with most highs about five to ten
degrees cooler than normal, from the mid 60s to within a few degrees
of 70.

Expansive cool high pressure will set up across the region Friday
night through Saturday night. This will keep our weather very quiet.

There will be minimal cloud cover along with refreshingly cool and
comfortable temperatures, making it feel more like early fall than
late summer.

Long term Sunday through Wednesday
High pressure will be anchored over the northeast this weekend, with
a cool NW flow aloft providing for comfortable levels of humidity
and just fair weather afternoon cumulus. The upper level trough will
exit Monday... And we'll be within a quasi-zonal flow aloft through
the remainder of the period with a upper level cut off low over the
midwest. We should hold onto our dry pattern through at least
Tuesday, if not Wednesday depending upon how quickly eastward this
upper level low advances.

The end of the month will finish with comfortable late summer
temperatures... Near the average of mid 70s... And dewpoints will be
comfortable, generally in the upper 40s to lower 50s. Nights may
become cool, with mid 40s possible early in the period across
interior valleys.

Aviation 10z Thursday through Monday
Ifr MVFR valley fog across the southern tier will persist through
sunrise... Before dissipating by 13z with renewed daytime heating and
mixing.

After the southern tier valley fog dissipates early this morning...

the combination of cool air aloft and daytime heating will again
lead to the development of a broken cumulus field in many areas...

with initial scattered lake effect showers along and a bit inland
from the south shore of lake ontario pushing inland and becoming
more diurnally-driven over time. While flight conditions will be
predominantlyVFR... A period of MVFR ceilings in lake effect clouds
will be possible south of lake ontario during the morning and midday
hours... With brief localized reductions to ifr MVFR also possible
within any showers.

Tonight any diurnally-driven shower activity will come to an end
early in the evening... With a few more isolated to widely scattered
lake effect showers then possible through the balance of the night
along and a little inland from the south shores of lakes erie and
ontario. Flight conditions will again be predominantlyVFR... With
some MVFR possible across the higher terrain and within any leftover
showers. Late in the night... Some ifr MVFR valley fog may redevelop
across the southern tier as skies partially clear... Possibly leading
to another round of restrictions at kjhw.

Outlook...

Friday... MainlyVFR.

Saturday through Monday...VFR.

Marine
With a rather cool airmass remaining in place across the lower lakes
region through Friday... There will be a continued potential for a
few waterspouts at times through the end of the work week... Mainly
in association with any showers or vertically-developed cloud bands.

Otherwise... Sprawling surface high pressure draped from central
canada to the mid-mississippi valley will gradually build southeast
across our region through the rest of the week and the upcoming
weekend. This will result in an extended period of sub-advisory
winds and waves across the lower lakes region... Particularly from
Friday on through the weekend when winds will average 10 knots or
less... And waves will be under 2 feet.

Buf watches warnings advisories
Ny... None.

Marine... None.
