.NEAR TERM /THROUGH FRIDAY/...
925 AM Update...

Some minor changes were made for this update but overall the
forecast is doing well.

640 AM Update

No significant changes. Touched up cloud cover based on the
latest visible satellite imagery and 09z HRRR. A few rain
showers will be possible along and north of I-90 now through mid
to late morning; just trace or a few hundreths of rainfall
expected here; dry elsewhere. Temperatures are starting off
between 55 to 65 out there early this morning. There is some
patchy fog around as expected. Generally, we are still expecting
the stratus cloud layer to scatter out, giving way to sunshine
by midday, with mostly sunny skies prevailing this afternoon.

215 AM Update

Much quieter, cooler and less humid weather expected for the
near term period.

Clouds linger through much of the morning hours today before
scattering out midday or early afternoon. The afternoon looks to
feature plenty of sunshine and drier air mixes down into the
boundary layer. Cooler temperatures, with highs in the upper
60s to mid-70 across Central NY with low 70s to low 80s in NE
PA. NW winds will be a little breezy later today, between 8-15
mph with gusts up around 20-25 mph expected. Winds quickly
diminish toward sunset and high pressure approaches.

Cool and mostly clear with light winds tonight as a 1020mb
surface high builds overhead. Overnight lows dip down into the
40s and low 50s areawide. This is 5 to 10 degrees below average
for late June, and will be quite refreshing.

Sprawling surface high pressure remains in place Friday
morning, only slowly translating east into New England by the
afternoon hours. After some patchy early morning valley fog,
skies will be sunny to mostly sunny through the day. With full
sunshine, went 1-2 degrees above the NBM temperature guidance
and also lowered surface dew points and RH to account for the
dry air mass centered over the region. Forecast highs are in the
mid-70s to lower 80s over the area Friday afternoon, this is
very close to average.

.SHORT TERM /FRIDAY NIGHT THROUGH 6 PM FRIDAY/...
315 AM Update...

High pressure slides east Friday night with clouds beginning to move
in ahead of our next low pressure system. Overnight lows will range
in the low 60s across most of the region with some spots in the
mid 50s. Rain showers and thunderstorms move in from the west
early Saturday morning as deep SW return flow advects moisture
into the region. Models continue to show PWAT values ranging 2-3
standard deviations above normal for this time of year with
values surpassing 2 inches. This along with a deep warm cloud
layer of 12-13K feet suggests conditions are favorable for heavy
rainfall that could lead to instances of localized flash
flooding. The convective potential at this time continues to be
unfavorable as the early arrival of rainfall should limit
instability. Rain showers are expected to continue into Saturday
night with a relatively warm temperatures as lows will range in
the mid 60s to low 70s.

&&

.LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/...
315 AM Update...

Cold front trails off a surface low in Canada kicking off
remnant showers and thunderstorms as this system tracks out of
our region. Chances of showers are expected mainly east of I-81
Sunday morning and afternoon. Overnight temperatures behind the
front will be cooler with lows ranging in the low to upper 50s.
Northwest flow over a `warm" Lake Ontario could produce some
showers early Sunday night. Added slight chance pops in
collaboration with our neighbors, otherwise showers will be
short lived and dissipate early Monday morning as dry air wins
out. Surface high pressure builds over the midwest Monday, but
upper level trough should keep temperatures relatively cool.
High pressure shifts east over our region by Tuesday allowing
temperatures to warm back up. Under this pattern conditions are
expected to remain quiet until midweek. Another surface low over
Canada is expected to track east with a warm front dipping into
our region by Wednesday kicking off showers. A cold front
follows behind with more showers possible for Thursday.

.AVIATION /14Z THURSDAY THROUGH MONDAY/...
645 AM Update

Patchy fog lingering INVOF BGM over the next hour, should lift
quickly. Otherwise, IFR CIGs are possible at BGM through about
13z or so. For the rest of the TAF sites MVFR/MVFR Fuel Alt CIGs
will be around through about 14-16z this morning, before
scattering out and becoming VFR midday.

VFR prevails areawide this afternoon, evening and likely most of
tonight. Cannot rule out valley fog at ELM, or patchy fog at BGM
late tonight & early Friday but confidence is low at this time
due to low level dry air in place and relatively short nights.

Light and variable winds are expected through the mid morning hours.
West-northwest winds become stronger by late morning into the
afternoon; between 8-15 kts with gusts 20-25 kts possible.
Winds quickly diminish under 10 kts toward sunset, and under 5
kts heading into the overnight.

Outlook...

Friday...Mainly VFR.

Saturday through Sunday...Restrictions from showers and
thunderstorms possible.

Monday...Mainly VFR.
