Lake Effect Summary - January 15-16, 2011
Maximum Snowfall: Lake Erie 4"
(Colden); Lake Ontario 22" (Fulton)
Duration: 30 hours +/-
Prime Feature: Evolved from synoptic snow, focus off Lake Ontario.
This event evolved gradually from a synoptic snow as a clipper
exited, with wraparound northwest flow following. Most areas
caught 1-3 inches from the synoptic event Saturday afternoon
(15th) then a brisk west to northwest flow of arctic air set in.
Dry air and low inversion heights limited activity off Erie to
multiple narrow bands withonly a few inches from southern Erie
to Chaut/Catt counties, but a strong upslope/lake effect band
developed Saturday evening off lk Ontario and focused on the Tug
Hill of Lewis county and extended back across far northern Oswego
and far southern Jefferson counties. A solid 6 to 10 inches fell
in this area by early Sunday. Then, after a lull, a narrow
intense band developed Sunday morning and lingered most of the
day on a more 290-300 flow, focusing on northern Cayuga and far
southern Oswego counties. Over 18" fell at Fulton. The activity
broke down Sunday evening and retreated out into the lake as
winds became L/V and even light southeast, with remnant of the
band lifting northwest to Toronto with heavy snow briefly there
Monday (17th) morning!
This was a decent buty fairly narrow event, falling on a weekend with limited impact. It therefore earns two ** stars.
Here are some representative reports.
