Muggy conditions will be felt across the Sauk Valley today as a warm front will advance north. Temperatures are expected to reach into the lower 90s for our region. Humidity will also rise into uncomfortable conditions, allowing our temperature to reach heat index values around 95°. We'll remain dry in our afternoon hours with some clouds dispersing.
While we will see temperatures in the 90s today, don’t be under the impression that it will stick around. A cold front will advance eastward tonight reaching Illinois overnight. As this progresses through Iowa, shower and thunderstorm activity is likely, but will be declining in intensity as it reaches Illinois. Severe weather chances will be very minimal to nonexistent from this system.
Due to the cold front that will move through tonight, we’ll rebound back to fall temperatures Friday, just in time for our autumnal equinox at 8:54pm this Saturday. Our weekend is favoring cool temperatures with an abundance of sunshine and dry conditions. We’ll return with precipitation chances by next week, but with cool temperatures continuing.
