Synopsis
Colder air flowing across the region will produce minor lake snows
east and southeast of lakes erie and ontario overnight and Wednesday.

Otherwise generally dry weather and below normal temperatures can
be expected through Thursday... Before milder conditions return for
Friday and the weekend along with increasing chances for some rain
showers.

Near term through today
In the wake of a cold front... A general westerly to northwesterly
flow of colder air will continue to produce some minor lake snows
east and then southeast of the lakes overnight... With the activity
shifting southward over time with steady veering of the low level
flow.

Off lake erie... The combination of the shortening fetch and
lingering ice cover will preclude much more than some weak lake
snows and accumulations of an inch or less overnight... With these
mainly focused across the higher terrain owing to orographic
influences. Meanwhile off lake ontario... The initially longer
fetch across the long axis of the mostly open lake and orographic
influences will help to maintain somewhat better organized snows
across the tug hill and higher terrain for a couple more hours...

where additional accumulations of 1-2 inches will be possible and
where a winter weather advisory remains in effect. After that time
the snows will weaken and shift southward to areas southeast of the
lake... Where another inch or so will be possible through daybreak.

Outside of the main lake effect areas... Much more scattered snow
showers will be the rule overnight... Along with much colder
temperatures that will fall back into the lower to mid 20s.

On Wednesday northwest winds, and diminishing lake effect snow
parameters will bring light snow southeast of both lakes through the
remainder of the forecast period. Additional snow SE of the lakes
will be just an inch or two. Highs will be not much higher than
tonights lows... With readings mostly peaking in the mid 20s.

Short term tonight through Friday night
Any lingering lake effect snow southeast of the lakes Wednesday
evening will diminish overnight into Thursday morning as high
pressure, subsidence and drier air builds across the region. With
this high pressure in control, expect a stretch of dry weather
Thursday through Friday. The surface high will settle across the
region on Thursday, bringing another day with high temperatures
slightly below normal, in the teens to mid 20s. Thursday night will
be another cold one, as the surface high settles to our the light
winds and clear skies will allow for temperatures to dip to near
zero in the north country. Meanwhile, for western ny, the return of
light southerly winds on the back side of the surface high will keep
temperatures near the 20 degree mark.

Temperatures will start another warming trend on Friday with return
flow developing as the surface high moves off the east coast. Highs
will range from the low to mid 40s in wny, to around the freezing
mark in the north country. Meanwhile, a trough moving into the upper
great lakes Friday night and Saturday will help amplify the
southwesterly flow across the region, increasing the warming
downslope flow Friday night into Saturday morning. This will make
for another mild night Friday night and perhaps even a few locations
in the genesee valley pushing 50 by Saturday. As we typically do
this time of year, we will pay the price for the warming with
increasing rain chances by later Saturday through Saturday night.

Long term Saturday through Tuesday
The upper level trough will be centered across the great lakes
Saturday night. Ahead of the trough, surface low pressure will be
moving across nys into Sunday morning. W-nw flow will begin in the
wake of the surface low cold front and cold-air advection will
begin by Sunday evening. A shortwave trough embedded in the main
trough may produce another round of precipitation, snow this
time, across the eastern great lakes into Monday morning. As
850mb temperatures drop to near - 12c lake enhancement will
likely cause snow to intensify downwind of the lakes. Lake
effect snow showers will linger behind the disturbance main
trough into Monday night- Tuesday as 850mb temperatures reach -
15c. Accumulating snow is possible during this time frame.

Sunday will see above normal temperatures before the cold air
advection begins Sunday night. High temperatures will be in the low
to mid 40s Sunday to upper 20s low 30s Monday and Tuesday. Low
temperatures will see the 20s Sunday night to the teens Monday and
Tuesday night.

Aviation 06z Wednesday through Sunday
Overnight areas of lake effect snow will produce localized
reductions to ifr east and southeast of the lakes... With much
more scattered snow showers and general MVFR ceilings otherwise
prevailing.

Wednesday and Wednesday night high pressure and drier air will
gradually build into the region... Which will force weak lake
snows southeast of the lakes to gradually diminish and eventually
end... While also helping ifr MVFR flight conditions to improve
toVFR.

Outlook...

Thursday and Friday...VFR.

Saturday and Sunday... Mainly ifr MVFR with rain showers likely.

Marine
Winds ahead of and behind a cold front will result in winds to
30 knots overnight, with small craft headlines in place across
most of the waters. Winds will diminish Wednesday as a ridge
axis passes across the great lakes later Wednesday.

Wednesday night and Thursday will bring an extended period of
lighter winds and waves 3 feet or less on the lakes... Into the
start of the weekend.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
