Leaving the window open for an overachiever I guess…
chances for snow ramp up near the lakes due to sw low-level flow, convergence ahead of the front and sufficiently cold air for a lake response. Majority of moisture is below 10kft but lift in that layer is decent as seen by low-level omega toward northeast end of both lakes. Since the arctic front does not arrive until after 09z east of Lake Erie and toward 12z or even afterward east and southeast of Lake Ontario, low-level flow does not veer too quickly, allowing sw-w flow to stay locked in place. Though not many models show it outright, did increase QPF/snow some to east of Lake Erie especially into Southern Erie and over western Chautauqua county given potential that stronger band forming this evening into Metro Buffalo could stall out for a while over these areas.
