Synopsis
A dry cold front will move across the region today while surface
high pressure builds into the region. This will result in quiet
weather for the remainder of the holiday weekend. The next chance
for rain will be on Tuesday.

Near term through today
With recent rain and a dry cold front still upstream of the region,
patchy fog and low clouds have formed over portions of wny and cny
overnight. With the region still in the warm sector with some
little low level mixing, much of the cloud deck is remaining aloft
and over higher terrain, although there is some advection fog near
the cooler lower great lakes too. Keeping track of low clouds vs
fog will be the main issue into the morning hours, with a close eye
on the potential for dense fog if winds let up.

Later this morning and into the afternoon, an MCS over the oh valley
should skirt to the south of the region. This should send some
higher clouds across portions of wny, but overall it should be a
quiet day in terms of weather. Dewpoints will be on the decrease,
while temperatures reach the lower 70s. The result will be a fairly
comfortable afternoon when compared to Saturday.

Short term tonight through Tuesday night
Following the passage of Sunday's cold front... Canadian high pressure
will ridge southeastward across new york state and provide our region
with quiet dry weather and comfortable temperatures for the remainder
of the long holiday weekend... With lows in the upper 40s to lower 50s
Sunday night followed by highs mainly in the upper 60s to lower 70s
on memorial day. As such... The holiday itself will be the best of the
three weekend days.

Monday night and Tuesday our weather will then deteriorate again as the
surface ridge slides off to our east... And gives way to an encroaching
warm frontal boundary and the first in the next series of waves rippling
northeastward around the periphery of upper level ridging anchored across
the southeastern states. The latest model consensus continues to suggest
convective chances returning from west to east Monday night out ahead
of these features... With the greatest potential for such found south of
lake ontario. Showers and storms should then become more numerous for at
least a portion of Tuesday as the wave passes directly across new york
state. With an overall warm air advection regime in place temperatures
will also be on the rise again... With the advancing warm frontal boundary
simultaneously dictating a decent northeast-southwest gradient in readings.

More specifically... Monday night's lows will range from the upper 40s
across the north country to the mid and upper 50s south of lake ontario...

with Tuesday's highs then similarly ranging from the upper 60s to mid-upper
70s... With some readings in the 80s not out of the question should portions
of the area manage to break into the warm sector and experience sufficient
dry time.

After that... The initial wave will slide off to our east Tuesday evening...

while a second and stronger wave develops into the upper great lakes.

With our area thus lying in between these two systems... Precipitation
chances should tend to temporarily decrease for Tuesday night... Though
with considerable uncertainty in the position of the lingering frontal
boundary will have to maintain at least chance pops to cover the potential
for any attendant widely scattered to scattered convection. Otherwise the
general upward trend in temperatures will continue... With lows ranging
from the mid 50s across the north country to the lower 60s across much
of far western new york.

Long term Wednesday through Saturday
Moving on into the longer term portion of the forecast... The second
and stronger wave appears as if it will push across southern ontario
and into western quebec Wednesday and Wednesday night... While pushing
an attendant warm frontal segment and or prefrontal trough across
our region between Wednesday and Wednesday evening. This should result
in the likelihood of yet another round of showers and storms crossing
our region during this time frame... With an attendant 50 kt low level
jet and sufficiently strong mid and upper level wind fields again
supporting a potential for some of these to become strong to severe.

Following the passage of this feature... Convective chances should
then again dwindle at least somewhat Wednesday night. With respect
to temps... Highs on Wednesday will be heavily dependent on the rate
of progress of the surface boundary and its attendant cloud precipitation
coverage. Currently readings from the mid 70s to lower 80s appear
to be a decent bet... However it should be noted that the increasing
warmth of our airmass aloft (850 mb temps pushing into the mid teens
celsius) would be enough to support readings of a category higher
than this in some locations should there turn out to be enough dry
time. Following this... Fairly widespread lows in the lower to mid
60s can then be expected for Wednesday night.

On Thursday surface low pressure will push further northeastward
across quebec province... And in tandem with an approaching mid
level trough will push its trailing cold front across our region.

This should result in another round of at least scattered showers
and storms. Canadian high pressure and cooler drier air building
into our region in the wake of the front should then bring a welcome
period of fair dry weather and more comfortable temperatures for
Friday and Friday night... With the latter returning to right around
normal levels for the end of may.

Finally... 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... Along with 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 06z 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 areas of ifr improving toVFR by afternoon.

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. They should 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.

Buf watches warnings advisories
Ny... None.

Marine... None.
