Dense fog persisted in some areas along the Wasatch Front, but easterly 10- to 30-mph canyon winds developed in the early morning, causing a slight weakening in the temperature inversion and a thinning of the fog in some areas.
"The fog is thinning and becoming patchy along the benches and away from the lakes," said Bill Cope of the Salt Lake office of the National Weather Service.The forecast for Monday night and Tuesday in the Salt Lake, Ogden and Provo areas is for partly cloudy, hazy and a little milder weather with patchy night and morning fog. Canyon winds will be 15 to 30 mph with higher gusts. An easterly flow of upper-level air is expected to continue through Tuesday, gradually weakening the inversion along the Wasatch Front.
Wednesday, the statewide forecast is for mostly cloudy weather with a slight chance of rain in the valleys and snow in the mountains. It will be fair to partly cloudy Thursday with patchy late night and early morning fog. Friday, clouds will increase again, bringing a chance of showers, mainly in the south and west. High temperatures Wednesday through Friday will generally be 35 to 45 degrees in the north and in the 40s and low 50s in the south. Low readings will be mostly 15 to 30 degrees.
