Despite continuing cold and often foggy conditions, tubers and sledders still head for the hills at Sugarhouse Park for some fun winter activities. Elsewhere, light snow fell Monday in the Brigham City and Cache Valley areas, and a little more snow is expected through Monday evening. A stronger storm system, forecast for Wednesday in western Utah and the mountains, could help eliminate the temperature inversion. The mercury rose to 30 degrees Sunday and dropped to 15 early Monday at the Salt Lake International Airport.
