The cool weather is due to a low pressure system over Northeastern Oregon that is drawing in colder air from the east Pacific Ocean, said Rob Brooks, a meteorologist with the National Weather Service in Pendleton.
Smoke from wildfires is expected to continue to be blown out of the region by winds that are predicted to continue sweeping over Northeastern Oregon the next few days.
"They are helping to scour the smoke out," Brooks said.
The meteorologist stressed there is no guarantee that new smoke from wildfires won't be blown into this corner of the state over the next three days due to the unpredictable nature of fire activity.
"We can not forecast wildfires," he said.
IQAir, a website that monitors air quality, is projecting that La Grande and Enterprise will have good air quality on Aug. 24 and Aug. 25.
