An early winter "lake effect" storm dumped 2 feet or more of snow on parts of western New York state on Friday, disrupting travel with bursts of icy powder blowing in from Lake Erie and Lake Ontario expected to pile up through the weekend. The squalls could persist through Sunday, creating sporadic blasts of intense snowfall along narrow bands that could amount to 4-1/2 feet (1.4 meters) of snow in some locations, according to National Weather Service forecasts.
