Outflow from a thunderstorm transports smoke from McKenney Fire 

The AlertWildfire camera in Northern California on Herd Peak recorded the effect of outflow winds from a thunderstorm affecting smoke from the McKenney Fire which at the time on July 31, 2022 had burned about 52,000 acres northwest of Yreka. It appears that the fire is spreading across the ground, but most likely it is just smoke.
