Synopsis
A cold front will move southeast across the region today while
surface high pressure builds into the region. This will result in
quiet weather for most of western new york, although there will
still be a low chance for a shower or thunderstorm over the southern
tier today. The rest of the area will remain dry for the remainder
of the holiday weekend. The next chance for rain will be on Tuesday
and Wednesday as another set of frontal boundaries move across the
state.

Near term through tonight
A fairly amplified upper level pattern remains over the country this
morning with ridging over the southeast and troughing over the west,
resulting in a fairly strong jet riding over the desert southwest
and across the plains, with continued bouts of resultant severe
convection. Meanwhile, a longwave trough resides over the hudson bay
region.

At the surface, the upper level pattern has led to a stacked low
near the hudson bay. Its warm front moved through earlier in the
weekend, while its cold front is poised to move through today. There
is scattered convection with this feature near the ottawa valley,
but the rest of the front should be mostly or completely dry as it
moves toward and eventually through western ny. This boundary is
weakly tied to an MCS that's moving east into the ohio valley.

As the front moves into the region, there is a chance
for some convection loosely tied to the front and or along a lake
breeze toward the southern tier. Convection may reignite near the
pa border later this afternoon from remnant moisture left over from
the ohio valley mcs. Other areas should be well capped without any
convection.

The other concern for today will be low clouds and or fog. This
will be variable over the west, partly tied to the relatively cool
waters ene of lake erie and early this morning over the higher
terrain, but expect an improving trend toward the afternoon. East
of lake ontario, low clouds and or fog may linger a little longer
into the afternoon.

Otherwise, the area will see variable high clouds from the MCS as it
weakens in the morning followed by some redevelopment later in the
day. With the cold front crossing the region, dewpoints will be on
the decrease, while temperatures reach the lower 70s. The result
will be a fairly comfortable afternoon when compared to Saturday.

Tonight should be quiet areawide with weak subsidence behind the
cold front and surface high pressure moving into the region. But
with continued decreasing dewpoints, clouds and fog should be less
of an issue. The lower dewpoints together with some clearing should
allow temperatures to drop to around the 50f mark give or take a few
depending on location.

Short term Monday through Wednesday night
Weak surface high will be in place across the eastern great lakes
Monday (memorial day) with mostly sunny skies and dry conditions for
a significant portion of the day. As we progress through the day,
mid and high clouds will begin to stream in from canada as a
weakening and rather moisture starved cold front drops south into
the forecast area. While a majority of the forecast area will likely
remain dry there will be the potential for a few sprinkles or even a
light shower across the north country as the front slips south into
the region. Otherwise, it will be a spectacular day across the area
with highs peaking in the 70s areawide. If you're planning on
heading to any of the lakes (erie or ontario) remember water
temperatures are still chilly, in the upper 40s to lower 50s.

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 09z Sunday through Thursday
A dry surface cold front will slowly move through the region today.

This will eventually help to clear areas of fog and or low clouds
with some areas of ifr improving toVFR by afternoon. Most of
western ny will be capped without any opportunity for convection.

However, the southern tier will not be capped, and may see a short
period of convection around midday with the cold front and or lake
breeze, with another chance late in the day as a weak system moves
through the ohio valley and into the mid atlantic states. Surface
high pressure should build into the region tonight for quiet
weather.

Outlook...

Monday...VFR. Tuesday... MainlyVFR with a chance of showers and
thunderstorms. Wednesday and Thursday... MainlyVFR with a chance of
showers and thunderstorms.

Marine
Wsw winds are expected today but stay below 18kts with little wave
action as the choppy waters will be closer to the northern shores.

Winds will gradually turn northwest by Sunday night into Monday and
weaken. The next chance for convection will be on Tuesday and again
on Wednesday, with some SCA wsw winds possible on Wednesday.

Buf watches warnings advisories
Ny... None.

Marine... None.
