The weather pattern is bringing in smoke from the fires in Douglas County. A graphic from the National Weather Service shows that wind is carrying from down south up to our area. The hockey-stick like lines are wind direction.
If you see a fire, or a definite column, please call an ODF office or 911. If it is for general haziness or smoke high up, it is most likely this drift smoke.
Unfortunately, this weather pattern is bringing with it a forecast for lightning. A probability map can be seen here:
