Lake Flake Scale: **** 4 Flakes

The 2003-04 winter season’s first surge of arctic air resulted in a major long lasting lake effect event. The bulk of the snow fell during the first couple of days in the more traditional snowbelts east of Lakes Erie and Ontario...but areas not as prone to heavy lake snows also shared in the action as the winds shifted later in the week.

The event began early Tuesday morning following a sharp cold front which ended a three week stretch of mild weather. Off Lake Erie...a strong westerly flow ignited heavy lake snowbands over southern Erie and Wyoming counties Tuesday morning (6th)...they then migrated south and then north...reaching the Buffalo South Towns for awhile Tuesday evening before settling south into ski country later Tuesday night and most of Wednesday before gradually weakening. Accumulations topped two feet over a large portion of northern Cattaraugus and Chautauqua counties with over 30 inches along the ridges. Ski areas were the beneficiary of the most snow. There was a sharp cutoff along the northern fringe with 8 inches in Orchard Park but 2 inches or less across most of metro Buffalo.

Lake Ontario provided more of the action...and a little more variety as well. The activity began on a westerly flow as on Erie...just a few hours later...but focused on the northern Tug Hill into southern Jefferson county Tuesday afternoon and evening before settling south across Oswego county early Wednesday. One to two feet fell in this area...with locally 30 inches on the southwestern Tug. The band settled south during Wednesday and edged onshore all along the lake from Wayne county back west into Orleans county. There was a marked variation across the Rochester metro with very heavy snow falling near the lake and sunshine south of the city. A weak backdoor front..or trof...dropped south across the lake and interacted with this band...perhaps intensifying it for a time later Wednesday and Wednesday evening. It weakened some later Wed. Night into Thursday as it drifted south to about the Thruway...but the trof re-established itself later Thursday and pushed south...reorienting the band to a more northeast to southwest look Thursday evening with several inches falling over Orleans and Niagara counties. The flow turned northeast later Thursday Night and Friday with a general light lake effect activity within 10-15 miles of the lake...with no more than a few more inches falling. The activity gradually tapered off Friday night but flurries still lingered into Saturday 10th . Totals across the Rochester area ranged from just a few inches near the Thruway to 8 inches downtown to almost 20 inches near the lake. The heaviest amounts there were Wednesday and Wednesday evening when band was west to east oriented.

The event was long lasting, had a wide scope and was intense at times.  It was the heaviest lake snow around metro Rochester area in the last 10 years.  It also replenished the ski areas which were in dire need since the early winter was warm and lacked much snow.   For those reasons it earns **** flakes.
