Forecast Discussion: Thur : PM2.5 readings have generally been good. More than 10 inches of snow has fallen over northern Kentucky (16 in Hardin County) and approaching that amount in far southern Indiana. Skies will clear tonight and the fresh snow will allow temperatures to fall sharply. High pressure settle down for a few days shifting winds around to the south tomorrow for a little melting. Each day temperatures will move a few degrees higher and Monday might be back to normal which will feel downright balmy.
