Utah — The Wasatch Front wakes under a muted gray sky as cold air sits heavy in the valley. Headlights glow through misty air, and the smell of winter lingers near the ground. Visibility remains reduced early, and the air feels still.
Salt Lake City begins the morning near 27°F with mist and pockets of patchy fog. Haze spreads across the valley, limiting visibility at times, especially between 8 a.m. and 9 a.m. Calm winds allow pollutants to remain trapped, a classic winter setup along the urban corridor.
As the morning progresses, fog thins, but haze persists. Skies trend mostly sunny later today, yet air quality remains a concern. Highs reach near 41°F, cool enough to keep stagnant conditions in place. Drivers should allow extra time on I-15, I-80, and surface streets where visibility may fluctuate.
Tonight stays cold and quiet. Temperatures fall into the mid-20s under widespread haze. Calm winds continue, reinforcing the stagnant air pattern. Sensitive groups should limit prolonged outdoor activity.
Saturday brings little relief. Sunshine returns, but haze remains widespread. Highs climb to the low-40s, with light and variable winds offering minimal mixing. Winter inversion conditions hold firm through Saturday night.
Sunday finally hints at change. Highs reach the upper 40s with sunny skies. Some improvement in air quality is possible late, though haze lingers into the evening. By Sunday night, skies turn mostly clear as lows dip into the mid-20s.
MLK Day delivers the cleanest stretch of the period. Bright sunshine and a high near 47°F help break the pattern. Monday night stays clear and cold near 28°F. Tuesday warms further, nearing 49°F, with better mixing expected.
