SPOKANE — With predictions of hot, dry temperatures continuing throughout the week, air quality predictions remained in the moderate health quality range Wednesday evening. The light haze of smoke hanging over Spokane Wednesday resulted primarily from the Upriver Beacon Fire that broke out north of the city a day earlier, but was augmented by fires in the Oregon Dalles, said meteorologist Steve Bodnar with the National Weather Service in Spokane. Air quality over the next several days remains difficult to anticipate due to uncertainty over future fire activity.
