WINONA, Minn.  – Every school district has weather-meisters whose job is to anticipate weather so severe that schools need to be closed. Most erred Thursday with early guesses that a two-hour delay would be in order. The situation deteriorated quickly. Most meisters then flashed new news: There would be no school at all. That was Thursday. What to do Friday? The snow had passed, but there was an arctic aftershock of chilling cold. Most school prognosticators on Friday decided on going two hours late, which seemed right on. There were districts, however, that called the full day off: Chatfield, Fillmore, Kingsland, Leroy-Ostrander, Lewiston-Altura, Stewartville, Wycoff St. John’s.
