The fire is burning in steep, rugged terrain in a rural area and firefighters have faced high heat, humidity and erratic winds, according to Cal Fire officials.
Better weather, however, allowed firefighters to make significant progress Thursday.
A road closure remained in effect two miles west of the Lake County line on Guenoc Road and Butts Canyon Road.
The fire is not posing a threat to Napa County's world famous vineyards so far.
The fire was first reported on Tuesday just after noon at a home north of the Aetna Springs Winery, off Butts Canyon Road, northwest of Lake Berryessa. The area is east of Calistoga and has a population of just about 600 people.
Cal Fire firefighters said it was the largest wildfire in the state in weeks. On Wednesday, Gov. Jerry Brown said he secured a federal grant to reimburse 75 percent of the firefighting efforts from a FEMA Fire Management Assistance Grant.
Vineyard manager Scott Brown told the Press Democrat that neighbors told him some young men accidentally started the blaze while cutting weeds using a tool with a metal blade. McLean said he was familiar with the allegation, but would not confirm the account to NBC Bay Area on Wednesday morning.
