Inversion conditions are trapping cold air and pollutants in the Treasure Valley, and the National Weather Service says thats not likely change anytime soon.
Thats what caused the haze over the Valley on Sunday. Warm air aloft from the West has trapped the cold air and is preventing the pollution from filtering out.
Cold air aloft or high winds would scrub out the dirty air, but thats not in the forecast until next weekend.
The high temperature in Boise on Sunday was 40 degrees. Highs this week are expected to be in the mid- to upper 40s, with overnight lows in the upper 20s and low 30s. Sunny skies dominate the Treasure Valley forecast through the Thanksgiving holiday.
