Nice little blurb about LES potential for S Shore:
A northwest flow regime continues Friday night. The best activity
continues to look to set up off Lake Ontario. Mesoscale model
guidance is not in particularly good agreement on where a Georgian
Bay connection will set up, but pattern recognition suggests this is
most likely across Wayne and northern Cayuga counties initially
during the first half of the night, possibly drifting southwest
towards Rochester late Friday night. If this upstream connection is
able to remain in one place long enough advisory criteria snow
amounts are possible southeast of Lake Ontario Friday night through
Saturday morning. In Rochester the greater snow amounts would likely
focus along Route 104 and into the eastern suburbs.
