We've enjoyed a couple of days this week with cooler temps and low humidity, but that will change as we head into the weekend. The combination of rising temps and higher humidity levels, means we will be talking about heat index values once again. In addition to the heat, some wildfire smoke may return to the state for the weekend. But some of the smoke might stay elevated bringing us some haze but not as many concerns with air quality.
