Synopsis
A very active pattern over the region through early next week will
support fairly frequent showers along with the risk for more strong
to severe thunderstorm activity at times. Otherwise... It will be
very warm and muggy through the middle of the upcoming week. Much
more comfortable conditions can be expected for the second half of
the week.

Near term through Sunday
As of 1025 pm largely dry conditions continue across the area... Save
for a couple tiny sprinkles across portions of the north country.

These general conditions will persist through the early overnight
hours... With some patchy fog forming in some areas as radiational
cooling allows dewpoint depressions to narrow.

As we head into the latter portions of the night... A shortwave
currently straddling the michigan-indiana-ohio border (and producing
convection over southern lower michigan as of this writing) will
push eastward across the lower great lakes. This next source of
forcing will once again activate the conditionally unstable airmass
with renewed convection becoming likely over the western counties
toward sunrise. While there will not be any help from an overlying
h25 jet and instability like that from this afternoon will not be
available... Bulk shear values in the vcnty of 30kts combined with
dcva attendant to the passing shortwave could help to enhance some
of the elevated convection... For which low likely pops remain in
play. Otherwise... It will be a warm and muggy late summer night with
mins in the low to mid 60s.

Sunday will start with weakening convection over the western counties.

As the driving shortwave moves across lake ontario to the st lawrence
valley by midday... The leftover showers and possible thunderstorms will
be over the north country. Subsidence in the wake of the shortwave will
bring a reprieve of several hours over the western counties... Then
another round of thunderstorms will be possible for the southern tier
and finger lakes as a likely lake breeze boundary will push east from
lake erie.

While the Sunday will not be a washout... It may prove to be
uncomfortable. H85 temps that will start off in the mid teens c are
forecast to climb to the upper teens late in the afternoon. Mixing
this airmass would normally promote MAX temps in the mid to upper
80s... But given the likelihood for debris clouds from the morning
and midday convection... Have dropped temps back a couple degrees
from continuity. Nevertheless... MAX temps in the low to mid 80s with
dew points close to 70 will translate into apparent temps in the
upper 80s to lower 90s for the lake plains.

Short term Sunday night through Tuesday night
This period will feature a continuation of warm and humid conditions,
with on and off chances for showers and storms.

A mid level shortwave and associated weak cold front will approach
our area Sunday night, then move through the region on Monday. This
will keep the chance for some scattered showers isolated storm in
the forecast for Sunday night, with better chances for convection by
Monday afternoon, as these features impinge on increased instability
owed to daytime heating. Increased southwest flow may lake shadow
areas northeast of lakes erie and ontario Monday afternoon.

The cold front will settle south of the area Monday night, then
stall out across northern pa and remain pretty much stationary
through the day on Tuesday. With no discernible mid level shortwaves
moving across the area during this time, will have just the chance
for a few showers isolated storm mainly across the southern tier and
finger lakes region closer the stalled boundary. Counties bordering
the southern lake ontario shoreline, east to the north country may
see mainly dry weather.

Stalled front across northern pa will start to slowly return north
as a warm front Tuesday night. At the same time, the next piece of
shortwave energy will approach the area. This will spread chances for
some showers isolated storms further north across the area, with the
best chance remaining across southern areas, with areas across the
north country once again having the best possibility of remaining
dry through late Tuesday night.

Otherwise, lowered temperatures a couple of degrees, however it will
still be on the warm side with fairly high humidity levels remaining
in place. Increased cloud cover ahead of the front on Monday, and a
slightly cooler airmass behind the cold front Tuesday will foster
highs generally within plus or minus a couple degrees of the mid
80s both days.

Long term Wednesday through Saturday
Warm temperatures will start this period on Wednesday before a cold
front tracks across the area. As the cold front tracks from west to
east, showers and thunderstorms will overspread the region on
Wednesday. Cold air advection will bring an end to the warmer than
normal temperatures for the remainder of the work week. With an
upper level trough still over the area, showers will be possible
through Thursday before increased ridging influences the area.

Friday and Saturday will experience dry conditions as this ridging
increases.

Temperatures will be in the low to mid 80s on Wednesday. Cold air
advection will bring a cooler airmass to the region resulting in
temperatures in the low to mid 70s for Thursday and Friday. Warm air
advection on Saturday will result in temperatures in the mid to
upper 70s across the area.

Aviation 03z Sunday through Thursday
Dry and mainlyVFR conditions will predominate through 06z tonight.

Another disturbance approaching from the central great lakes will
then bring another round of scattered to numerous showers and some
thunderstorms to far western new york late tonight and early Sunday
morning... Along with possible attendant reductions to MVFR. Patchy
fog developing overnight may also produce some localized reductions
to ifr MVFR.

Vfr to MVFR CIGS will then be found over the region for at least the
first half of Sunday morning... As the disturbance and its weakening
convection will push from the western counties to the north country.

MainlyVFR weather is then expected for the midday and afternoon...

except for areas inland from the lakes where daytime heating and
developing lake breeze boundaries will help to generate another
round of scattered to numerous convection and associated brief
localized restrictions.

Outlook...

Monday...VFR to MVFR in scattered to numerous showers and
thunderstorms.

Tuesday...VFR... With a chance of showers and thunderstorms south of
buffalo and rochester.

Wednesday... Thunderstorms likely that could impact operations.

Thursday... MainlyVFR.

Marine
A weak pressure gradient will maintain generally light to modest
winds across the lower great lakes through the rest of the weekend
and into early next week... Along with correspondingly minimal waves.

The above said... There will also be the risk for some showers and
thunderstorms later tonight Sunday and again Sunday night and
Monday... Some of which could produce locally stronger winds and
higher waves.

Looking further out into the middle of next week... A cold front
will cross the region on Wednesday along with more showers and
thunderstorms. In its wake... Increasingly brisk northwesterly
winds will bring an increase in wave action and could eventually
require the issuance of small craft advisories for Wednesday night
and Thursday.

Buf watches warnings advisories
Ny... None.

Marine... None.
