A dense fog advisory for the Inland Northwest has been extended until 4 p.m. today, the National Weather Service stated. An air stagnation advisory has been continued through Tuesday afternoon.
Because the still air is trapping pollutants, such as smoke and vehicle exhaust, air quality is suffering, according to the weather service. Those with respiratory conditions should check with their doctors about what to do, officials said.
Temperatures will not vary much with a high of 30 and a low of 28 predicted today, according to the weather service.
The fog, still air and below freezing temperature weather pattern will repeat itself through the weekend.
