Synopsis
Scattered snow showers will persist today as a band of snow
drops south across our region. High pressure will build in this
evening, keeping our weather quiet tonight into Sunday. Another
storm will bring light snow Sunday night.

Near term through Sunday
130 pm update...

a large area of lake effect snow show continues to affect our
ny counties, with moderate snow observed near the onondaga
cayuga cortland county borders.

None of the mesoscale models are doing a particularly good job
diagnosing the les this afternoon, so we populated the grids
with a blend of rap and hrrr and amended based on current
observations.

Bottom line is we expect another half-inch to an inch of
accumulation today downwind of the lakes, with slightly higher
amounts in isolated squalls.

High pressure will bring dry conditions to our region tonight
and Sunday.

Short term Sunday night through Tuesday
A wave of low pressure will slide eastward across the great
lakes Sunday night. Snow accumulations will be light, mainly
from a few tenths of an inch to an inch. Temperatures will range
from the teens over oneida county to the upper-20s over luzerne.

Warm advection will increase on Monday when a cyclone over
ontario province pulls southwesterly flow into ny and pa. A mix
of rain and snow showers is forecast. A wide variability of
temperatures, from the middle-30s over the western mohawk
valley to the lower-40s in the wyoming valley, is expected
across the region.

Temperatures falling into the lower and middle-30s will cause
another rain snow mix Monday night. Little accumulation is
forecast.

Tuesday will be mild with rain showers tapering off.

Temperatures will reach the 40s.

Long term Tuesday night through Saturday
Cold front moves through the forecast area Tuesday night.

Precipitation is expected to change over to snow as the boundary
layer cools in wake of the front. Given the moisture depth from
forecast soundings, low-level flow, and water temperatures over the
southeastern part of lake ontario, we could see a decent lake-effect
snow event set up over northern parts of the forecast area. As such,
precipitation probabilities will be greatest over this region. The
odds of seeing snow will start to diminish by Wednesday night, after
a shortwave trough axis shifts east of the region.

Surface high pressure is forecast to move into the region under a
nearly zonal flow aloft by Thursday, resulting in what'll likely be
the driest day of the upcoming week. That'll likely be short-lived,
though, as synoptic scale lift ahead of a deepening storm system in
the plains ushers the possibility of precipitation back into the
region by Thursday night. Warm advection occurring in a
southwesterly flow ahead of the next cold front should result in the
snow at least mixing with (if not changing to) a cold rain in most
areas by Friday afternoon.

Temporal and spatial uncertainty increases in the day 6-7 time frame
between the major medium range models. In general, the cold front
should move west to east across the forecast area Friday night, with
precipitation changing back to snow in wake of the front. The snow
showers should continue across parts of the region into Saturday.

Aviation 00z Sunday through Thursday
A weak band of snow will continue to impact kith, kelm, kbgm and
kavp through about 02-03z this evening with MVFR vsbys and cigs.

After 03z, conditions are expected to becomeVFR at all
terminals. These conditions will persist tonight and most of the
day Sunday. The next system will approach from the SW during the
afternoon with ceilings likely becoming low-endVFR at kelm,
kavp, and kbgm before 22z.

Outlook...

Sunday night to Tuesday... Possible restrictions in rain or snow
showers.

Wednesday... Restrictions possible again in lake effect snow
showers mostly in central ny.

Thursday...VFR possible.

Bgm watches warnings advisories
Pa... None.

Ny... None.

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.
