Lake Effect Storm Itchmite January 25-26, 2007
Maximum Snowfall: Lake Erie 6"
(Sherman); Lake Ontario 10" (Rochester)
Duration: 24 hours +/-
flow multiple band event.
Events continued to come fast and furious in the cold pattern change. Successive subtle trofs continued to drop southeast across the
region, with one just after midnight on Thursday 25th dropping a general inch or so across most areas. However, as the cold
air deepened, a narrow band of heavier snow developed right along the lakeshore of Monroe county and extended southeast into western Wayne
County. This dropped 6 to 9 inches in just a few hours from the lakeshore of Irondequoit southeast across Penfield Webster and Pittsford.
There was a sharp cut off as the city received only an inch or two. The activity weakened during the day until a 320 flow of arctic air set
off multiple bands in the evening, but these only dropped a few more inches all along the lakeshore from Niagara to Oswego County.
Off Erie, less activity was observed. A few inches fell during the late morning and early afternoon Thursday but this was at least partially
related to a synoptic (frontal) feature.
The event was marginal but id affect a heavily populated area, the first significant snow in the Rochester metro in two years. It therefore earns
two ** stars.
