A weekend weather system could hamper firefighters' efforts in Northern California to battle the week-old blaze that’s become the largest in the state so far this year.
The system is forecasted to bring colder temperatures and precipitation — from 1/4 inch (0.63 centimeters) to more than 1 inch (2.54 centimeters) of rainfall over several days — to the Mosquito Fire about 110 miles (177 kilometers) northeast of San Francisco.
