Lake Effect Summary - January 8-10, 2007

Maximum Snowfall: Lake Erie 18" (Perrysburg); Lake Ontario 19" (Highmarket) 

Duration: 42 hours +/- 

Prime Feature: Typical classic type WNW event.

After a long period of unprecedented unseasonal warmth, the weather pattern finally buckled enough to allow for a surge of seasonably cold air to overspread the Lower Lakes region during the second week of January. This finally turned on the lake effect machine, a bit more than forecasted even as the lakes were at record warmth. Lake snows began late Monday afternoon in a northwest flow following a frontal passage, with a bit of upslope component Monday night, then a narrow band of intense snow moved in off Erie after midnight and focused on southern Erie, Wyoming, and the northern portions of Chautauqua and Cattaraugus counties through mid morning Tuesday ahead of a weak trof. Up to a foot fell in a narrow band…but this snow was most welcome for ski areas and snowbelt locations. Virtually nothing fell from Orchard Park northward. Off Ontario, a similar band developed over the Tug.
The activity broke apart and spread out a bit later Tuesday and Tuesday Night as flow turned northwest following the trof with some subsidence, then intensified a bit again off Ontario later Tuesday night and early Wednesday as flow backed to 320, even clipping eastern suburbs of Rochester. Activity ended Wed Afternoon as ridge built across and cap lowered.
Total amounts were as much as 16-19" in heaviest areas, but dropped off substantially elsewhere. The metro areas of Buffalo and Rochester escaped with an inch or less.

The event was a relatively long lasting one but had little impact as it fell mostly over snowbelt ski type areas, although it did have some effect on Jamestown and Dunkirk. It therefore earns two ** stars.
