DISCUSSION...
Our main concern for thunderstorms today is with a line of storms
from southern Iowa into western Illinois that will spread across
areas south of I-88 this afternoon. Significant severe winds and
even a few tornadoes would be favored south of I-80 with this
system. Farther north up to around I-88, scattered thunderstorms would
pose a wind threat with gusts to 60-70 mph, and even a few instances
of damaging hail.
There is another smaller chance for thunderstorms this evening, closer
to the Illinois Wisconsin state line. Damaging hail and winds are
possible, though confidence on there being storms in this time
is low.

Smoke from wildfires in Canada is moving into the region, pushing air
quality into the unhealthy or worse categories. Air Quality Index
(AQI) forecasts and levels can normally be found at AirNow.gov, but
the unique widespread nature of this episode prompted this extra
alert.
Active children and adults especially people with pulmonary or
respiratory disease such as asthma should avoid long or intense
outdoor activity. Everyone else should reduce outdoor activity.
Residents are urged to reduce pollution levels. Air quality
forecasts and tips on how you can reduce your emissions can be found
