A Hazardous Weather Outlook is in effect for the western two-thirds of Utah as forecasters warn of a slowly building winter storm system through the week ahead.

The seven-day advisory began Tuesday, when locally light snowfall was predicted by evening in the northern mountains and valleys, with some heavier amounts noted in Weber County Tuesday afternoon. By Thursday night, though, a stronger, second pulse of winter weather was expected to bring "significant snow accumulation" to the region, especially along Interstate 15 from the Idaho border all the way south to near Cedar City.

That activity should keep the state's air quality at pretty good levels. The Utah Division of Air Quality was forecasting "yellow," or moderate breathing conditions for Salt Lake, Davis, Utah, Weber, Cache and Uintah counties into Wednesday with the remainder of the state's monitoring districts at "green," or healthy. Continuing storm activity later this week should bring more air quality improvements.

The Wasatch Front looked for high temperatures in the upper-30s to low-40s on Wednesday with overnight lows in the mid-20s, an echo of Tuesday's forecast.

Southern Utahns were on tap for highs in the low- to mid-50s with lows around 30 degrees.

The Utah Avalanche Center rated the Uinta Mountains at "considerable" for potentially deadly snowslides with the remainder of the state's mountains earning "moderate" avalanche risk grades.
