Inversion traps pollutants in Valley, triggers air quality alert. How long will haze last?

December 30, 2013 

The potato will drop in Downtown Boise on Tuesday, but will we be able to see it?

In a word: Yes.

The minor haze caused by an inversion — cold air and pollutants trapped in the Valley — may get pushed out by a system coming through Monday night, according to the National Weather Service. The mountains may get some snow as well.

The Idaho Department of Environmental Quality issued a yellow air quality alert for Monday due to stagnant air. Outdoor burning is prohibited in cities in Ada and Canyon counties, as well as unincorporated Ada County.

Fog was affecting visibility in the Valley on Monday morning. At 7:30 a.m., visibility was 4 miles at Boise Airport and 5 miles in Nampa and Caldwell.

Highs this week will be in the mid- to upper 30s (Friday could reach 40), and lows will be in the mid- to upper 20s. A system coming through Friday may bring some precipitation; it's likely to be rain, a National Weather Service meteorologist said.
