Hiker James Dorum surveys the thin ice on Dog Lake Monday morning. Although it's not winter yet, the 5 inches of snow by the lake, at about 10,000-foot elevation, between Mill Creek and Big Cottonwood canyons, sets the stage for what many hope will be a good water year in Utah. But it's no guarantee, says National Weather Service meteorologist William J. Alder. A storm, forecast for Friday, could bring a little snow in the mountains above 9,000 feet. Widely scattered rain showers are possible Friday and Saturday in northern Utah valleys. The Oct. 19 storm deposited about 8 inches of snow at Alta, 8 to 10 inches at Elk Meadows and 12 inches at Hidden Peak, at the top of Snowbird. Temperatures were expected to reach a high of about 60 degrees Tuesday and the upper 60s Wednesday along much of the Wasatch Front.
