Lake Effect Summary - December 16-17, 2009
 


Maximum Snowfall:Lake Ontario 15" (Scriba) 

Duration: 24 hours +/- 

Prime Feature: Marginal NW flow event with good Georgian Bay connection.

The 2009-2010 lake effect season's second storm was a marginal one and restricted mainly to Lake Ontario. It began following a cold front as a westerly flow set off a band of fairly heavy lake snows by midday Wednesday 12/16 across portions of northern Oswego and southern Lewis counties. The flow veered to northwest Wednesday evening and snowbands shifted south across Oswego county. A good streamer off Georgian Bay reached western Lake Ontario and was enhanced as it crossed the lake right across the Rochester metro area which received several inches of snow during the evening. Winds veered further overnight and Thursday morning and remnants of the band drifted southwest and coated the Buffalo area with an inch or so. Meanwhile, another streamer developed over eastern Lake Ontario and dropped several inches as it crossed western Oswego county on a NNW flow Thursday morning and midday. The activity was squashed by high pressure and a lowering inversion by afternoon.

This event was relatively minor with few effects…although it did drop several inches on greater Rochester but it was during the mid and late evening with minimal traffic impact. Heavier snows were restricted to a small area in western Oswego county. It therefore earns one * star.

Here are some representative reports.
