Synopsis
Colder air will work into our region tonight, and generate light
lake effect snow and flurries through Wednesday across upstate
new york. High pressure will build in Thursday and Friday with
dry weather.

Near term through Wednesday
The cold front is passing through ny pa at this time with winds
shifting to the west. Scattered light shower activity will
continue through the afternoon hours, and then a lake effect
band will form this evening, producing rain showers initially
before cold air moves in and changes the precipitation to snow.

Snow showers will continue over our far northern forecast area
through Wednesday, shifting from northern oneida to onondaga
county as the winds fluctuate. We expect 1 to 3 inches of snow
over an 18-24 hour period.

Temperatures will be more seasonable Wednesday. Temperatures
will reach into the middle and upper-20s in the afternoon, then
fall off to between 10 and 15 degrees Wednesday night.

1100 am update...

moderate to heavy rain is moving northeast of the forecast area
and should be out of our region in the next hour. In the
meantime, we are watching river levels and a few ice jams.

Scattered showers will remain over ny and pa through this
afternoon. Light lake effect snow will move into our far
northern counties after sunset.

Short term Wednesday night through Friday
High pressure will dominate the short term. Surface ridge builds
in Thursday bringing an end to the lake effect snow showers. A
clear night and light winds will bring a chilly
night... Especially east of i81 for Thursday night into Friday
morning... With lows near zero over oneida county. On Friday,
high slides east and warm air advection begins. Upper ridge is
still building so it will remain dry, and Sun will help boost
afternoon temps into the 30s.

Long term Friday night through Tuesday
Southwest flow of warm air develops behind the ridge, bringing
increasing moisture as well. Clouds will increase on Saturday,
with showers breaking out Saturday night. Euro has not caught up
with the GFS and sped up the passage of the front by late
Sunday, with cold air advection developing Sunday night into
early Monday. This will allow some of the rain to turn to snow
on Monday. A few snow and rain showers will linger into Monday
under the upper low and with the cold advection.

Aviation 00z Wednesday through Sunday
Flow will shift from southwest to northwest overnight and bring
increasing low level moisture including enhanced moisture from
lake ontario. A low level inversion will keep the stratocumulus
over the region through much of Wednesday. At krme ksyr, lake
effect snow showers will drop into the terminals around 05z with
MVFR conditions and occasional ifr between 06z-12z. After 15z,
MVFR ceiling will prevail but the snow showers should diminish.

At kith kbgm, conditions will lower into the MVFR category this
evening with occasional alternate required late tonight into
early Wednesday. MVFR ceiling are expected to continue through
Wednesday. At kelm, ceilings falling into the MVFR category
after 06z then improving to lowVFR after 15z. At kavp,VFR
forecast with ceiling around 4k feet.

Southwest winds at 12-15 knots with gusts 20-30 knots shifting
to the northwest later tonight at 12-15 knots with gusts 20-25
knots.

Outlook...

Wednesday night... Possible continuation of flight category
reductions and a chance of shsn.

Thursday through Saturday...VFR under high pressure.

Saturday night through Sunday... Restrictions likely in light
rain.

Hydrology
345 am update... Localized flooding due to ice jams is possible,
mainly through tonight. Rainfall amounts today are expected to
range mostly from 0.25-0.75", with locally higher amounts
possible in the poconos and western catskills. The snow pack
water equivalent going into this event was generally around 1
inch or less.

So, the combination of rain and snowmelt runoff will cause
rivers to rise which may break up the ice currently in place.

This may result in jams downstream. The most rainfall is
expected across the susquehanna river basin in northeast pa and
the delaware basin in ny and pa. However, ice jams can occur
along any rivers in our area. Overall, rain amounts,
temperatures, and snowmelt point to an isolated threat of ice
jam flooding, at worst. We will continue to monitor the
situation closely, and if higher rainfall amounts are observed,
or were to appear more likely, a flood watch could be issued at
that time.

Bgm watches warnings advisories
Pa... Flood watch until 7 pm est this evening for paz040-044-047-048-
072.

Ny... Flood watch until 7 pm est this evening for nyz057-062.

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.
