Dense fog continues to blanket the Lower Treasure Valley, and the National Weather Service has extended the Dense Fog Advisory until 2 PM MST Thursday.
Webcams and predictions show no major improvement before Friday, with recurrent patterns of chilly temperatures, gloomy skies, and mild winds.
Change is on the way this weekend. A cold front will pass through Saturday night, bringing gusty winds and colder air, which should lift the inversion.
As blocked cold air disperses, lower valleys should warm by 5-15°F on Sunday, while mountain areas will cool by 10-20°F.
Rain and snow are predicted Saturday night, with snow levels ranging from 4,500 to 6,000 feet. Light snow accumulation is possible in the highlands, with limited influence on valley levels. The dry, cold weather returns on Monday.
