It may not be Beijing (cough!), but the Wasatch Front continues to battle with (cough!) its own brand of gunk and haze (cough!) in the winter air (cough, cough!).

The Utah Division of Air Quality has declared another "unhealthy" day Saturday for Cache, Salt Lake and Utah counties. That means these groups in those counties should reduce prolonged or heavy outdoor exertion and stay mostly indoors: people with lung disease such as asthma, children and outdoor enthusiasts.

The unhealthy air is expected to continue in those three counties through Monday. The air will be declared "unhealthy" in Weber County on Monday. That also means that the rest of the weekend and Monday will be "no burn days," where it is restricted to use the following: fireplaces, wood and pellet stoves, outdoor fireplaces or fire pits, charcoal grills, smokers and coal-burning stoves.

The air quality is likely to remain the same through the week, with the first possible break on Thursday when a snowstorm is expected to move in.

Saturday's high temperature in Salt Lake County is expected to reach 23 degrees with an overnight low of 15. Highs will remain below freezing and in the low- to mid-20s through Wednesday. Overnight lows will be in the mid-teens.

Highs in northern Utah will continue to be in the mid-20s through Wednesday, with lows in the single digits. Highs in St. George will be in the upper-30s and low-40s this week, with lows in the mid- to upper-20s.
