Substantially higher humidity, lighter winds, and the possibility of drenching thunderstorms had firefighters battling the huge PK Complex brush fire in north Texas more optimistic on Saturday than they have been in days, officials said.

The weather could also help control some of the other fires that have been ravaging parts of the state.

The monstrous PK Complex brush fire has charred 148,000 acres and destroyed nearly 300 structures, including 167 homes.

“Everyone is optimistic, things are looking good,” Haven Cook, Public Information Officer for the Southern Area Incident Management Team, said at a media briefing Saturday morning.

The management team is leading the tanker trucks, aircraft and more than 400 firefighters arrayed against the fire,

Cook said the fire — actually a combination of four separate fire covering two counties which merged near the resort community of Possum Kingdom Lake about 70 miles west of Ft. Worth — is listed at 25 percent contained.
