Synopsis
High pressure will build across the great lakes today bringing
clearing skies and seasonable temperatures. Our next storm system
will bring rain later Thursday into Friday. Temperatures will run
near to slightly above normal through Friday.

Near term /through tonight/
High pressure will build across the great lakes today bringing
drier air and seasonal temperatures. Inland patchy morning fog
and low clouds have dissipated nicely and will continue to be
replaced by inland horizontal roll convective clouds, mostly
south of the finger lakes and/or higher terrain to the south in
the upslope northerly flow. The only other concern for today is
the stratus deck seeping south across lake ontario. This will
occasionally move across the shoreline, but there should be
enough mixing from isolation to prevent this from making much
progress past roughly the thruway, with the exception of
eastern lake ontario which is already underneath this blanket.

This cloud deck should start to deteriorate this afternoon as
the moist layer thins out. The remainder of western ny should
see sunny skies with temperatures near normal with highs in the
40s.

Tonight high pressure will settle across the region with mostly
clear skies and light winds resulting in decent radiational cooling
conditions. Low temperatures will drop below freezing for most
locations, with the coldest readings in the mid 20s in the north
country.

Short term /Thursday through Friday night/
Expansive high pressure centered over northern quebec Thursday
morning will move slowly but steadily eastward, allowing low
pressure to eject from the central plains. Mid and upper level
moisture and lift increases along a boundary that extends well out
ahead of the system. Model soundings point to a dry sub 700 mb layer
which will persist into Thursday afternoon. This should help to
delay the onset of precipitation until mid to late afternoon over the
western counties. Otherwise, lowering and thickening clouds can be
expected over our region during the course of Thursday with
temperatures climbing to near 50 degrees in the west and the mid 40s
for the north country.

Increasing isentropic ascent and strong northward moisture transport
Thursday night will overcome in-place dry air across the area from
southwest to northeast. Thus, a steady increase in precipitation
with the steadiest/most widespread precipitation arriving during the
late evening/overnight hours and continuing through at least Friday
morning. Model soundings do not suggest steep enough lapse rates
aloft, so without significant elevated cape, will continue to keep
the mention of thunder out of the forecast.

For the most part precipitation type should not be an issue, with
most expected to fall as rain as a lack of true cold air helping to
sufficiently warm boundary layer temperatures. However, the
expectation could be across the north country as marginal thermal
profiles could allow for a brief period of mixed precipitation late
Thursday night/early Friday morning.

The complex system responsible for the all of the unsettled weather
will push to our east by Friday night. While the bulk of the
associated lift and mid level moisture will be removed, there will
still be the chance for some leftover showers, especially along and
east of the axis of the surface trough, which will be aligned over
the genesee valley for the first half of the night. Some of the
lingering precipitation could change to a wintry mix late.

Long term /Saturday through Tuesday/
There is high confidence that this will be a relatively mild
period... As a progressive ridge will make its way across the eastern
half of the country. This ridge will also keep the bulk of the
period rainfree. The tranquil weather will come to an end though by
Monday night and Tuesday... As the next southern stream system will
lift northeast out of the lower mississippi valley. The details...

a storm system exiting off the east coast will support some leftover
nuisance showers across the region Saturday morning. In its wake...

expansive high pressure centered over hudson bay will build south
across the lower great lakes Saturday afternoon through Monday. This
will promote fair dry weather. While high temperatures will
generally be in the 40s on Saturday... The mercury will climb into
the 50s for Sunday and Monday.

Monday night and Tuesday... Low pressure over the lower mississippi
valley is forecast to push north towards the lower great lakes. Most
of the ensemble members of the GEFS along with the operational
ecmwf track the broad low to our west within a negatively tilted
trough... Which will once again set up a scenario where we experience
another round of rain.

Aviation /14z Wednesday through Sunday/
Vfr conditions are expected through Thursday. High pressure
will be north of lake ontario with light northerly flow today.

There is a stratus deck over lake ontario and eastern lake
ontario, but CIGS are near 5000'. This will not make much
progress to the south today, and it should start to mix out in
the dry airmass later this afternoon. Winds will shift to the
east overnight and Thursday. Eventually higher clouds will move
into the region, with slowly lowering CIGS during Thursday
afternoon.

Outlook...

Thursday night into Saturday... MVFR/ifr with rain showers.

Sunday... Some improvement toVFR possible.

Marine
Light northerly winds will persist today as strong canadian high
pressure builds across the great lakes... However winds and waves are
expected to remain below advisory levels. Winds will turn easterly
Thursday and Friday as our next storm system passes south of the
great lakes. Winds will approach 15-20 knots but higher waves should
remain in canadian waters.

Buf watches/warnings/advisories
Ny... None.

Marine... None.
