BOISE, ID—A cold front is predicted to move over the Pioneer Fire today, which may help decrease fire activity.
The Pioneer Fire is now 184,376 acres and 56 percent contained.
Fire officials report containment lines continue to hold and secure the fire’s edge along the northwestern flank of the Pioneer Fire.
In spite of the favorable forecast of cooler temperatures, it will take a few days for the fuel moisture to recover after the drying trend that took place over the past few days. Smoke is expected to remain in the area as interior fuels continue to burn.
Smoke concentrated in the low valleys this morning, then mix down to the surface for much of the day. Most of the areas will see a clearing in the early to late afternoon as daytime mixing peaks. Smoke will again settle into the valleys in the night time. Today, the most significant smoke impacts will be in Garden Valley, Lowman, Stanley and Fairfield areas.
