WEDNESDAY NIGHT: A few isolated sprinkles during the evening, otherwise becoming partly cloudy late. Light northerly winds. Low: 55.
THURSDAY: Following a damp, dreary, and cool Wednesday, partly to mostly sunny skies return thanks to Canadian High Pressure just to the north of Chicago.
This will bring more seasonable 70s back to much of the area, with the lone exception being locations in close proximity to Lake Michigan where a northeasterly lake breeze will result in temperatures about 10-degrees cooler, in the lower to middle 60s.
While the partial sunshine will be a welcomed return, the Illinois Environmental Protection Agency has issued a Air Quality Alert in effect until midnight Thursday night due to an increase in particulates from Wildfire smoke.
The Air Pollution Action Day designation was issued for Cook, DuPage, Kane, Kendall, Grundy, Lake, McHenry and Will counties. Active children and adults, especially people with pulmonary or respiratory disease such as asthma, should limit prolonged outdoor activity.
Air Quality: What's the AQI and how do you check it?
Regional air quality is expected to reach the 'Unhealthy for Sensitive Groups.' It's the first Air Pollution Action Day issued by the Illinois EPA so far this year. The EPA's site provides updated air quality information.
