Lake Effect Storm Katydid January 31, 2007
Maximum Snowfall: Lake Erie 8"
(Perrysburg); Lake Ontario 35" (Redfield)
Duration: 18 hours +/-
After a brief interlude of less than 24 hours from the previous event, a strong westerly flow reignited lake snows off both lakes early
Wednesday morning. The activity was very intense off Lake Ontario, focusing near the Oswego-Jefferson County line and extending right
across the Tug Hill. Snow fell at 2 to 4 inches per hour and piled up to 1 to 3 feet on the southwestern Tug. The activity broke up a bit
and lifted north in the evening as shear increased.
Off Lake Erie, a broader area of disorganized lake snow prevailed through most of the morning before it consolidated into an intense west
to east band over Chautauqua and Cattaraugus counties at midday. This band lifted north across Buffalo's south Towns by late afternoon,
but dissipated right as it reached Buffalo due to increasing southerly shear. The movement of the band precluded heavy accumulations with
most areas only seeing heavy snow for an hour or two, with totals generally 4 to 6 inches with a few outliers of up to 8" on the Chautauqua
ridge and over to Ellicottville.
This was the sixth event of the month, and fourth in a week.
The event was intense only off Lake Ontario and very narrow but affected little population. It therefore earns
two ** stars.
