As Orem wishes its residents "Season's Greetings," 24-year-old Jon Backus prepares for the season by . . . mowing his lawn? Despite the warm weather, Orem decided it was better to be safe than sorry. City officials usually put up the signs after Halloween, but they heard a storm was coming and public service workers could be occupied with other duties in the near future. Orem citizens can apply the greeting to whichever season they want. Happy Halloween. Forecasters at the Salt Lake office of the National Weather Service say there's no trick. Stormy weather is on the way. Significant amounts of moisture are expected beginning tonight in northern Utah and Thursday in southern Utah. One to 2 feet of snow are likely in the mountains. The snow level will drop to near 5,000 feet in northern Utah Thursday. Cold, wet conditions are likely to continue into the weekend. .
