A cold front that made its way across the Great Salt Lake with a spectacular lightning show Saturday night was expected to blow through the Wasatch Front Sunday, scattering thundershowers and dropping temperatures.

The cold front crossed the Idaho border about 8 p.m. Saturday night and let loose a lightning display over the lake. It was expected to move into the Wasatch Front about midnight and linger through Sunday morning.Rick Watling, public forecaster for the National Weather Service in Salt Lake City, said the storm could be expected to drop temperatures as much as 10 degrees.

Watling predicted the mercury would only rise as high as 85 degrees and fall as far as the mid-50s on Sunday. Winds accompanying the cold front were expected to reach up to 35 mph.

He said there was a 30 percent chance of thundershowers in the Salt Lake area Sunday.
