Synopsis
Notably less humid conditions will be in place for the next several
days as an expansive area of canadian high pressure builds across
the great lakes. While western and north-central new york will be
able to enjoy fine weather through the weekend, an unusually well
organized mid summer storm system will dump excessive rains over
parts of pennsylvania and the mid atlantic region.

Near term through Saturday
Tonight, our region will remain between the the center of high
pressure over the michigan up and a strengthening coastal storm
moving off the delmarva. This will keep a northeast flow steady
through the night while skies become more clear across upstate ny
with the depart of the coastal storm. No precipitation is expected
and the steady winds should prevent much of any fog development. A
drier airmass will allow for a cool night with temps dipping into
the 50s.

Saturday, high pressure will remain anchored over the northern great
lakes. The presence of deep layer subsidence and persistent north to
northeast low level flow ensures dry and stable conditions will hold
throughout the period. Plenty of sunshine and lower humidity will
yield pleasant summertime conditions with afternoon high
temperatures in the lower to mid 70s.

Short term Saturday night through Tuesday night
Deep-layered ridging will be the dominant weather feature across our
region for the first 36 hours of this period... And as such we can
expect fair dry weather to continue right through Sunday night... Along
with mainly clear skies at night and mostly sunny conditions by day.

Temperatures will also remain at comfortable levels... With lows Saturday
night ranging from the upper 40s in interior portions of the southern
tier and north country to the mid and upper 50s along the lakeshores...

highs on Sunday mainly in the upper 70s to lower 80s... And lows Sunday
night ranging from the mid 50s to lower 60s.

On Monday the axis of the aforementioned ridging will slip off to our
south and weaken... Allowing a weak mid-level shortwave and attendant
weak surface trough over ontario province to sink toward the north
country. In conjunction with daytime heating and a moderate increase
in humidity levels... This feature could help to touch off a few isolated
to widely scattered showers and storms across the saint lawrence valley
Monday afternoon... With another isolated shower or storm also not out of
the question along and inland from a developing lake erie lake breeze.

Otherwise the vast majority of the day will be dry... With slight warming
of our slowly modifying airmass allowing temperatures to climb back into
the lower 80s in many locations.

Whatever widely separated convection that forms Monday afternoon should
then quickly fall apart Monday evening with diminishing heating. This
should allow for a dry and quiet night... With the warmer and somewhat
more humid airmass translating into warmer overnight lows ranging from
the upper 50s to mid 60s.

On Tuesday another mid-level shortwave will cross our region... And this
in conjunction with daytime heating and a continued slow increase in
humidity levels should lead to the development of another round of
widely scattered to scattered convection away from the lakes... For
which a mix of slight chance to low chance pops remains in place from
continuity. Otherwise we can expect another day with highs mainly in
the lower 80s... While dewpoints will creep back up into the lower to
mid 60s and lend a noticeably more humid feel to our airmass.

As was the case the day before... Any diurnally-driven convection on
Tuesday should quickly fade out with the loss of heating and the
departure of the responsible shortwave Tuesday evening... Leading to
a return to dry weather for the balance of the night. Meanwhile
temperatures will again be warmer than those of the previous night...

with lows ranging from the lower 60s across interior sections to the
mid and upper 60s along the lake plains.

Long term Wednesday through Thursday
Another round of convection will be possible Wednesday afternoon as
heights begin to fall ahead of a more substantial upper level trough
over the upper great lakes. Thursday currently appears to be the most
promising day for widespread rainfall of the period, as a slow-moving
cold front is forecast to advance across the region as a deep upper level
trough digs across the great lakes.

We should see a gradual warm-up through the middle of the coming
week, as a return flow around high pressure over the southeast
begins to advect warmer and more moist air into the great lakes.

Temperatures will return to the 80s in both Tuesday and Wednesday
afternoon, and dewpoints returning to the 60s will bring mugginess
back into the air. Thursday may run a little cooler, in the mid to
upper 70s, pending the anticipated widespread precipitation. The more
humid airmass eluded to above will result in warmer nights, with
lows in the low to mid 60s.

Aviation 18z Friday through Wednesday
High pressure over lake superior will allow for mainly dry weather
this afternoon and tonight along withVFR cig vis. The position of
the high will also bring a steady northeasterly flow through
tonight. There may be a few isolated showers that try to sneak into
the western southern tier of ny this afternoon, but confidence is
too low to include in kjhw TAF at this time.

Any low mid clouds around this afternoon will become mainly thin
high clouds tonight with some clearing occuring late from north to
south. No fog expected tonight as winds will remain steady from the
northeast overnight.

Outlook...

Saturday through Monday...VFR with only the chance for late night
ifr MVFR vsbys across the southern tier.

Tuesday... MainlyVFR. A slight chance of showers and thunderstorms.

Wednesday...VFR MVFR. A chance of showers and thunderstorms.

Marine
A fresh northeasterly flow will persist over the eastern great lakes
through tonight as an area of high pressure over the upper great
lakes ease southward. Small craft flags will remain in place on the
western two third of lake ontario and from dunkirk to ripley on the
east end of lake erie.

Winds will diminish Saturday afternoon and will likely drop below
small craft criteria by early Saturday evening. Variable, gentle to
moderate breezes will then remain for the remainder of the weekend
and into early next week, providing excellent recreational boating
conditions.

Marine
Northeasterly flow has set up over the eastern great lakes as an
area of high pressure has centered over lake superior. This flow
will continue through Saturday morning at generally 15-20 knots,
while producing waves of 2 to 4 feet for the lake ontario nearshore
waters west of sodus bay.

On lake erie, winds will yield the highest waves on the western
waters of the lake, with waves 3-5 feet from ripley to dunkirk.

Otherwise, high pressure over the eastern great lakes will bring
fine boating conditions continuing through the weekend.

Tides coastal flooding
A storm system developing over the middle atlantic states
today into Saturday will combine with high pressure over the
upper great lakes to produce some elevated northeasterlies on
lake ontario. Recent model guidance has backed off on the
strength of the northeast winds, now only 15-20 knots, such
that the risk for additional significant erosion and flooding
along the south shore of the lake is now reduced. Have cancelled
the lakeshore flood watch for niagara county to wayne county
with waves only expected to reach 2-4 feet.

Buf watches warnings advisories
Ny... None.

Marine... Small craft advisory until 2 am edt Saturday for lez040.
