On Tuesday the Pioneer Fire in central Idaho continued its march to the north, adding another 16,000 acres to bring the total to over 157,000 acres. Burning 32 miles northeast of Boise and 23 miles west of Stanley, it has been creating huge convection columns rising 30,000 feet into the atmosphere for the last two days.

Most of the growth on Tuesday was on the north side while it was pushed by an 8 to 12 mph wind gusting at 18 to 24 that was variable, but mostly out of the south. As we write this at 2:50 p.m. on Wednesday, the wind so far today has been out of the west and northwest at 4 to 10 mph with gusts of 16 to 24. The smoke being pushed to the east will probably make the air quality rather unpleasant in Stanley, due east of the fire.
The fire was very active late into Tuesday night due to the low relative humidity which ranged from 24 to 30 percent during the night at the White Hawk weather station at 8,344 feet elevation. At 2:33 p.m on Wednesday it was 66 degrees with 21 percent humidity.

The Pioneer Fire is one of five currently active fires in the United States that are staffed by more than 1,000 personnel.

As of Tuesday evening the total number of resources assigned to fires in the US included 444 hand crews, 1,060 engines, 147 helicopters, and 19,064 personnel. When the number of crews approaches 500 and there are almost 20,000 personnel committed, you know things are getting busy.

The Fire Weather Research Laboratory from San Jose State University is conducting research from an aircraft flying over the Pioneer Fire in central Idaho. Today using N2UW, a twin engine 1977 Beech 200T King Air, they flew for over three hours at 27,000 feet studying the fire for the RaDFire project.
The aircraft is outfitted with a ton of instruments including Doppler radar. Craig Clements, Associate Professor in the Meteorology Dept. at SJSU, described it for us:
The radar is called the Wyoming Cloud Radar (WCR). It’s on the aircraft, points up, down, and down-forward to get horizontal winds and vertical winds. The goal of the RadFIRE (Rapid Deployments to Wildfires Campaign) is to get data on plume dynamics from ground based mobile Doppler Lidar. But we were awarded 10 flight hours to test the WCR to see if it works in smoke plumes. And it does so well, more than we can imagine!
The group has been known to fly through the convection column. I’ve done that a few times and it’s an interesting experience — it can get a little turbulent, as you might expect.
On Monday they said the top of the pyrocumulus cloud over the fire topped out above 30,000 feet. In Tuesday’s photos it was at about 25,000 feet but toward the end of the day the top got up to at least 32,000 feet, Mr. Clements said.
The project is sponsored by the National Science Foundation and it’s being led by San Jose State University. Other collaborators on the project are David Kingsmill at the University of Colorado Boulder, and the University of Wyoming King Air team.
Since it started on July 18 the Pioneer Fire has burned over 140,000 acres.

This last photo of the convection column was not taken by the researchers. It was shot by Steve Botti in Stanley on August 29, more than 20 miles away from the fire.

(UPDATED at 11 a.m. MDT August 6, 2016)
The Pioneer Fire at Lowman, Idaho, 32 air miles northeast of Boise, Idaho, continued to spread up the steep slopes after it crossed highway 17 Friday afternoon pushed by thunderstorm-generated winds gusting up to 35 mph. Spot fires initially occurred over the roadway west of the burnout firefighters were conducting near Lowman to protect the community. By 2 a.m. aerial mapping showed the fire had spread about 1.2 miles north of the highway and consumed an additional 1,200 acres.
On Friday the fire grew by about 6,700 acres, to 58,136 acres.
The video below of firefighters working along Highway 21 was posted by the incident management team on August 5.

The incident management team’s plans for Saturday, in part:
Crews will look for opportunities to bring dozer line north from Burns Ridge down to the river west of the fire in an effort to create a new containment line. North of the river the fire is established in steep slopes with light grassy fuels. Aircraft this morning will survey the fire west and north of Lowman looking for suitable places to build containment lines. The possibility of another thunderstorm today or tomorrow brings potential for stronger wind gusts, which could create more extreme fire behavior.

A strong south wind added to the complexity of the burnout being carried out since Thursday by firefighters in an effort to stop the Pioneer Fire from impacting the community of Lowman, Idaho and crossing Highway 21. Sustained winds at 20 mph with gusts of 28 to 40 mph pushed the blaze across the highway Friday, significantly increasing the workload now laid out before the incident management team.

Evacuations have been ordered by the Boise County Sheriff’s Office for some areas near the Payette River, and Highway 17 is closed. The fire is 32 air miles northeast of Boise, Idaho.
The 52,000-acre fire is being fought by 1,489 personnel, 43 hand crews, 52 engines, and 10 helicopters. Five structures have been destroyed.

The incident management team running the fire led by Beth Lund is about to time out, so a replacement has been ordered which will inbrief at 9 a.m. on August 8.
Drones shut down air operations over the Pioneer fire for 45 minutes on Sunday, while the fire continued to spread due to erratic weather conditions.
In a post on InciWeb, the incident management team said the drone incursion came at a critical time for firefighters.
Aviation operations once again stopped for 45 minutes during a critical period of fire suppression due to an unmanned aircraft incursion. IF YOU FLY WE CAN’T. PLEASE DO NOT FLY DRONES IN OR NEAR THE FIRE AREA.
Such a delay seems to have become common place on many fires, and last week incident management teams in California and Montana reported halting air operations due to drones in the area.
A spokeswoman for the National Interagency Fire Center has urged people not to flying drones into wildfire areas, and has said that people caught flying drones in wildfire zones could face criminal charges.
Meanwhile, the Pioneer fire has burned 27,271 acres and is 27 percent contained.

Crews on the 18,933-acre Pioneer fire north of Idaho City are facing a weekend of windy weather, which will likely fan the flames of a fire that has been burning since July 18.
Here’s the outlook for Sunday’s weather:
A passing cold front this evening may produce thunderstorms with gusty, erratic winds and increased fire behavior.Smoke will likely again be visible from great distances.
Crews are also grappling with poor access, steep terrain, dry forests and old mining sites, according to posts on InciWeb.
On Friday, heavy smoke from the fire drifted east and triggered warnings for unhealthy levels of smoke pollution. Smoke from the Pioneer fire was also drifting into Northern Colorado.

The heli-rappellers at the Salmon, Idaho airport saw the lightning strike on July 26 that caused the Comet fire 12 miles north of the town. So far it has burned 356 acres above the Salmon River near Highway 93.

Secretary Jewell discusses the rehab of the Soda Fire and the illegal occupation of a National Wildlife Refuge.
In an interview with Rocky Barker of the Idaho Statesman, Secretary of the Interior Sally Jewell talked about the rehabilitation of the Soda Fire that burned 279,000 acres in Oregon and Idaho southwest of Boise last August. She addressed some of the criticism about the rehab strategy and also talked about the illegal occupation of the Malheur National Wildlife Refuge in Oregon and its effect on the U.S. Fish and Wildlife Service employees.
