(Richmond, IN)--Road crews across the Whitewater Valley are gearing up for a long weekend battling heavy snowfall with expected drifting.  One of the elements that will make it difficult to clear road is that temperatures are expected to be too cold for salt to be effective.  The latest update from the National Weather Service in Wilmington, which was issued at 1:30 Friday morning, has Wayne County in the 8-12 inch range.  If that comes to fruition, it would be one of Richmond’s top three snowfalls this century.  The city’s largest-ever 24-hour snow total came in December of 2004, when 13 inches fell.  In February of 2009, Richmond had a nine-inch snowfall.
