The veil of haze that drifted over Billings and much of central Montana on Friday came from the dozens of wildfires burning in Idaho and western Montana, according to the National Weather Service in Billings.
The 40-plus active wildfires in Idaho, Montana and Wyoming had burned a total of about 485,000 acres as of Friday night, according to incident reports.
The air flow pattern carrying the smoke from Idaho and western Montana is expected to change from southwest to west over Saturday and Sunday, which will direct the smoke more over Wyoming, said National Weather Service forecaster Tom Humphrey.
“It should get a little better as we head into Saturday and Sunday,” he said.
But as long as the fires continue, more haze is possible in central Montana if the wind conditions continue to bring the smoke east and northeast, Humphrey explained.
Seven active wildfires that have burned about 18,400 acres were reported in Wyoming on Friday.
The largest of those, the Hardluck fire in the Shoshone National Forest, had burned 16,100 acres and was still uncontained on Friday.
Officials said residents in Cody and surrounding communities should expect smoke and haze from the Hardluck and other fires in the region.
A handful of fires started by lightning were reported to be burning in Yellowstone National Park on Friday as well.
The largest of the fires, the Alder fire, was estimated to be about 50 acres Thursday evening.
It was discovered on Wednesday on Promontory Peninsula in Yellowstone Lake.
The fire was expected to grow Friday and campsites on the peninsula have been closed.
A cold front forecasted to move over the area late Saturday and Sunday “could bring limited relief and even a chance for some isolated showers and thunderstorms” park officials said in a news release.
In Idaho, officials reported 19 active wildland fires that had consumed more than 432,000 acres by Friday evening.

About 300 personnel were still fighting the fire, according to the most recent reports on the complex. Officials said the Pony Complex is in the “mop-up and monitor stage,” except for some areas on the northwestern flank of

The nearby Elk Complex fire was reported to be 50 percent contained after burning more than 125,000 acres and destroying some 80 buildings.

In Montana, the active wildfire tally is at 15, with those fires having burned a total of more than 35,000 acres, according to inciweb.org, an interagency information website for wildfires.
The largest of those fire systems, the Gold Pan Complex, has burned about 18,000 acres in the Bitterroot National Forest.
The fire is actually burning just west of the Montana state line in Idaho, but the U.S. Forest Service office involved in handling the fire is headquartered in Hamilton.
