Significant snow accumulations are expected before the current Lake Effect Snow Warning for Northern Erie, Niagara, Orleans and Genesee Counties expires 6 p.m. Friday. But this is mostly a northerly event, which National Weather Service forecaster Bob Hamilton says will lose some steam as it moves out of the metro region. "Looks like anywhere from 5 to 9 inches in the warned area of maybe 10 inches across parts of northern Erie County most of them falling bring the first half of today that snow will then weaken and head south to the e Southern tier where they're looking at a general three to fix it about," Hamilton. Areas south of the city will be under a Lake Snow Advisory beginning at 1 o'clock Friday.
