Synopsis
Cold and windy conditions are expected through tonight with
lake effect snow accumulation over the northwest alleghenies and
laurel highlands. Thanksgiving week looks mainly dry with
temperatures trending milder to above average into Tuesday
before cooling off to near seasonal levels for the rest of the
week.

Near term until 6 am Monday morning
Cold northwest flow will produce lake effect and orographic
snow showers through tonight. Temperatures falling below
freezing this evening and into the 20s overnight should easily
allow snow to accumulate over the NW alleghenies and laurel
highlands. Stayed close to hires ensemble mean for total snow
accumulations of 2-4" with localized 4-6" in the perennial lake
effect belt north of route 6. Elsewhere expect c-1" with perhaps
a bit more (up to 2") on the ridges and summits over the laurel
highlands. Minimum wind chills will drop into the teens and 20s
into Monday morning.

Short term 6 am Monday morning through Monday night
High pressure passing to the south of pa should shift back the
lake effect snow trajectory to more of a wsw-ene orientation
and focus snow showers into southwest ny by Monday afternoon.

Cloud cover to the east of the alleghenies should decrease with
mostly cloudy skies trending to partly mostly sunny by late in
the day. MAX temps still chilly and few degrees below average
for mid late november. Min temps may occur early over the
western higher elevations as southwest winds increase into tue
morning.

Long term Tuesday through Sunday
The extended part of the forecast will see the season's first
real lake effect snow event winding down early in the period,
followed by several days of cool but tranquil weather.

High pressure will keep conditions dry into Tuesday before a
weakening front sliding by to our north brings the small chance
of a snow shower to northern areas Tuesday night and Wednesday.

Another area of high pressure will build east and keep us mainly
dry at least through the end of the week, before a new frontal
system takes aim at the area.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
