Weather change should help MT air quality

Helena was the only place showing "unhealthy" air Wednesday afternoon(MISSOULA)- A combination of early morning fog and afternoon haze that's been occurring across Western Montana should be coming to an end, as an incoming system helps to end inversions that were setting up over the valleys. 

Tuesday, warmer air aloft was beginning to trap smoke and other particulates in the valley floors, beginning to create air quality that was unhealthy for young children, the elderly and people with respiratory problems. 

But by mid-day Wednesday, Montana DEQ monitors were only showing air quality problems in the Helena valley. Most other locations, including the Missoula and Bitterroot Valleys, and Northwest Montana were showing "moderate" air quality. 

With the forecast for a return to mix rain and snow Thursday it's expected slick driving conditions will be more of a problem than air quality for the remainder of the week.
