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.
