Synopsis
A passing cold front may touch off a few spotty showers and
thunderstorms across the southern tier today... With fair dry
weather otherwise prevailing as surface high pressure builds
into the region behind the departing cold front. Dry and
comfortable weather will then persist through the remainder
of the holiday weekend... Before a wavy frontal boundary
pushes into our region and brings a return to unsettled
weather for most if not all of the upcoming work week.

Near term through Monday
As of this writing... Any fog from earlier this morning is now
confined to a couple of still-shrinking areas over and a little
inland from the northeastern portions of lakes erie and ontario...

with this expected to continue to thin and eventually entirely
dissipate by midday. Otherwise the area is mostly quiet and dry
aside from some spotty showers near the ny pa border... With
cloud cover varying widely from sunny mostly sunny skies across
the bulk of the niagara frontier and finger lakes to partly to
mostly cloudy conditions across the north country and southern
tier.

Through the rest of today... A weak cold frontal boundary will
continue to make its way southward across our region. The passage
of this boundary will be mostly dry... Save for across the southern
tier where it (and the northern remains of a weakening MCS passing
by to our south) will interact with somewhat deeper lingering
moisture modest diurnal instability and thus help to generate a few
spotty garden-variety showers and thunderstorms as we move through
the day. North of this... Partly to mostly sunny skies and dry
weather will prevail. Otherwise we can expect a fairly comfortable
afternoon... With temperatures mostly ranging in the lower to mid 70s
(possibly upper 70s across the warmer interior portions of the
finger lakes)... And dewpoints lowering into the 50s following the
frontal passage.

Tonight will be quiet and dry areawide as high pressure over
manitoba and the upper great lakes builds into the region behind the
weak cold front and provides further subsidence and drying... Which
should result in low clouds and fog being much less of (if any)
issue. Coupled with skies becoming partly cloudy to mainly clear
areawide... The drier airmass and lightening winds should allow for
overnight lows to settle into the upper 40s and lower 50s.

For the memorial day holiday... The center of the surface ridge
will settle directly across southern ontario and quebec. While
a shortwave diving southeastward across quebec province will try to
push a very weak cold front through this ridge and into our
region... The lack of upper support and only limited moisture
accompanying this boundary will result in this generating little
more than some partial cloud cover across lake ontario and the north
country. Otherwise it will be a simply salubrious day with a fair
amount of sunshine only giving way to some increasing mid and high
clouds across far western new york late... And high temperatures
mostly peaking in the upper 60s and lower 70s... Save for the south
shores of both lakes where an onshore flow off the chilly lake
waters will help to keep conditions notably cooler.

Short term Monday night through Wednesday night
Monday night, a surface base ridge to our northeast will likely
keep the area precipitation free, at least for the first half
of the night. With that said, an advancing warm front will be in
the process of lifting to the northeast which with moisture
ramping up (pw values nearing 1.5 inches) will likely lead to
increasing chances for showers and or thunderstorm by daybreak
Tuesday. Showers and storms will continue for a significant
portion of the day Tuesday as a weak wave tracks across new york
state. With its passage late in the day evening, showers and
storms will decrease in coverage until the next stronger wave
arrives as we head into Wednesday, more on that a bit later.

Lows Monday night will have a wide range with upper 40s across
the north country to the mid and upper 50s south of lake
ontario. Highs Tuesday will follow a similar pattern with mid to
upper 60s east of lake ontario(a bit cooler)and upper 70s near
80f elsewhere.

Tuesday night, the next wave will quickly race out of the midwest
and track into s. Ontario on its way towards western quebec by
Wednesday. While it tracks ene it will nudge a warm front northward
and then send a prefrontal trough across the area on
Wednesday Wednesday evening. With ample moisture in place and
supporting 40-50 knot LLJ yet again its likely another round of
showers and thunderstorms will be possible some of which could be
strong to severe. Following the passage of this feature convective
chances should then tail off again to a degree Wednesday night.

Highs Wednesday will likely be the warmest day of this period with
temperatures pushing into the upper 70s to lower 80s. Lows Tuesday
night will range from the mid and upper 50s across the north country
to lower 60s south of lake ontario. Wednesday night, lows areawide
will be in the 60s by day break Thursday.

Long term Thursday through Saturday
The last in a series of waves will push across the forecast area
Thursday with another round of scattered showers and or
thunderstorms. Thursday night, with its passage into quebec canada
and then into labrador strong surface ridging over the upper great
lakes will build east with cooler drier air filtering into our
region in the wake of the front. This will bring a much needed
period of fair and dry weather with more comfortable temperatures
for Friday and Friday night.

The surface ridge will slide off to our east on Saturday while
allowing the next wave of low pressure and its trailing cold front
to approach our region from the northwest. This could result in a
renewed potential for some scattered showers and storms as we
progress through the day, especially across the western southern
tier. It will also send temperatures climbing back into the 70s
areawide as a southwesterly flow of warmer air overspreads our
region in between the departing high and advancing low.

Aviation 15z Sunday through Thursday
A weak cold front will slip southward through the region today and
will pass through most of the area dry... Save for the western
southern tier where somewhat deeper moisture modest instability and
the lack of a cap may allow the front to generate a few spotty
showers and thunderstorms with attendant brief localized MVFR
conditions. Otherwise increasing subsidence and drying behind the
front will help to clear lingering ifr MVFR conditions across the
southern tier and north country... WithVFR conditions otherwise
prevailing. GeneralVFR conditions and dry quiet weather should then
prevail tonight as high pressure builds further into the region.

Outlook...

Monday...VFR.

Tuesday... MainlyVFR with a chance of showers and
thunderstorms.

Wednesday and Thursday... MainlyVFR with a chance of showers
and thunderstorms.

Marine
Modest westerly winds (strongest across central and eastern
portions of lake ontario) will continue through the rest of today...

however conditions will remain well below advisory levels. Winds
will then veer to northwesterly and lighten tonight... Before turning
more northerly on Monday as the center of surface high pressure
slides into southern ontario and quebec.

Chances for showers and thunderstorms will then return Monday night
and Tuesday and last through most of the upcoming week as a wavy
frontal boundary pushes northward into the lower great lakes... With
the next chance for advisory-level southwesterlies arriving
Wednesday and Wednesday night.

Buf watches warnings advisories
Ny... None.

Marine... None.
