Lake Effect Summary - December 13-17, 2010

Maximum Snowfall: Lake Erie 22" (Perrysburg); Lake Ontario 35" (Lacona) 

Duration: 96 hours +/- 

Prime Feature: Long lasting NW flow event with strong Georgian Bay connection.

After a respite of a few days, the Lake Effect machine revved up again following the passage of a storm which brought a cold rain to most of the area on the 12th. This event was very long lasting and features three "sub" events, although it never really ended until later Friday 17th. Most of the accumulation occurred during these three "sub" event periods, a north to northwest "upslope" flow from late Monday (13th) through Tuesday morning (14th) which brought 6-10 inches from Monroe to Wayne county and over a foot to the Chautauqua ridge, a rare narrow but intense band from Georgian Bay which worked slowly across the Niagara frontier during afternoon of Tuesday 14th, dropping 4 to 7 inches, and a broader WNW flow off the east end of Lake Ontario on Wed Nt/Thurs morning 15-16th which nailed Oswego county with over a foot.

Again, lighter activity continued outside of these periods but accumulating snow fell at least until Friday. The 4 day totals topped two feet over much of Wayne and Oswego counties and over a foot back across Greater Rochester as well as over some higher elevations south of Buffalo, but overall the event was not too disruptive (only Mon Nt Rochester, Tues pm Buffalo, Wed nt Oswego) and was well spread out.

This was a fairly unique and long lasting event but with modest impact. It therefore earns three *** stars.
