Air quality worsens for some as Canadian wildfire smoke drifts in

Heat Advisory Update:

Another heat advisory has been issued for portions of the Stateline. This time, it includes a few of our northern Illinois counties including Jo-Daviess, Carroll, and Stephenson Counties. This is set to run from 12PM to 8PM today. When you combine high temperatures in the low 90s and dew points on either side of the 70-degree mark, heat indices will wind up in the lower 100s this afternoon.  

Air Quality Alert Update:

Along with the summer heat, periods of wildfire smoke can occasionally drift in, creating concerns when it comes to air quality levels. For that, the EPA has kept McHenry County and the Chicago metro under an Air Quality Alert until midnight. However, added to it is southern Wisconsin which will be under the alert until noon Thursday.   

Air quality as of this morning is already registering at moderate levels and should stay that way as we get into the afternoon. Levels should drift south into the "unhealthy for some" category Thursday. 
 

Hot, Hazy Wednesday:

Similar to the past few days, today will begin with the potential for patchy dense dog. Some, especially out near the Mississippi River, have seen visibility fall to 5 or 6 miles. Use extra caution as some patches will be thicker than others. Due to the fact that we will see some of that wildfire smoke filter in, skies will be hazy but still dry as high pressure remains in control of our atmosphere. Expect highs in the low 90s.
