Lake Effect Summary - February 9-11, 2011
Maximum Snowfall: Lake Erie <2" ;
Lake Ontario 25" (Pulaski)
Duration: 60 hours +/-
Prime Feature: Shifting winds, exclusive Lake Ontario event.
The season's 8th event was a rather typical late season one, and
as usual, in February, was restricted to Lake Ontario. The event
evolved from a synoptic one, with westerly winds just cold enough
to set off some Lake Effect bands during the early morning hours
of Wed. 9th across Oswego county. The winds backed ahead of a short
wave trough during the day Wednesday and the activity consolidated
into a single intense plume across north central Jefferson county
just north of Watertown during the afternoon, up to ten inches
fell near Theresa. The winds veered with passage of the trough but
the band again consolidated, this time over northern Oswego and
west central Lewis counties. It became very intense later in the
evening and into the wee hours of thurs 10th. Some 19" fell in
Pulaski from 9 pm to 3 am. The activity drifted south near
daybreak and held closer to the Lake as winds lightened, with
another 6" near Oswego in the morning. The activity then
weakened with increasing shear and lifted north Thurs afternoon
and continued overnight Thurs Nt over Jefferson county when the
Watertown area caught 3-5". It weakened further up by the St.
Lawrence valley on Friday morning 11th. Winds backed further
with increasing shear and virtually shut down the activity by
Lake Erie was about 95% frozen and could do little more than
produce some flurries across the Buffalo area at times.
This event has some decent totals, but was spread out and had limited impact. It therefore earns two ** stars.
Here are some representative reports.
