LAKE EFFECT STORM "DARWIN"
December 4, 2002
Lake Flake scale: * 1 Star
Maximum Snowfall: Lk. Erie: 4" (Perrysburg); Lk. Ontario: 8" (Sodus Bay).
Duration: 18 Hours +/-
Prime Feature: Rather unusual weak NNW flow in arctic air. (Tea kettle flavor)
Lake Flake Scale: * 1 Flake
Following the major event of December 1-2, an arctic airmass overspread western and central New York. Temperatures fell to zero or below well inland. A weak northwest flow set up some lake effect snows near the Lake Ontario shore overnight on 3rd..which intensified after midnight on the 4th. It had somewhat of a "tea kettle" flavor as surface winds were light...setting up convergence just south of the lakeshore from Monroe to Cayuga counties. A narrow strip of 4 to 8" fell from Webster to Sodus Bay to Fair Haven by late morning on the 4th (Wed.). As winds picked up during the day...the band reoriented across Oswego county and became quite heavy for a few hours as it lifted north across the county before breaking apart by early evening as a major synoptic system began to approach from the south...disrupting the wind fields.
There was also a more limited response off Lake Erie...but amounts were less and insignificant.
Overall...this was a marginal event with little impact. It barely earned a name but was a bit unusual and did reach the criteria of 7". It earns just a single (*) star rating.
Here are some representative amounts ....
