(OLNEY/NEWTON) After some area patchy fog this morning, we’re back to a mostly clear sky today with plenty of sunshine as a weak cold front extending from central Wisconsin southwestward to just north of Kansas City slowly sags in our direction. However, most all of Illinois’ shower and thunderstorm activity will stay to our north as that frontal boundary stalls out north of a line along Interstate 70. That frontal boundary will eventually wash out across central Illinois tomorrow, which means more heat and humidity in place for our downstate region as move through a dry and warm upcoming weekend. A series of short wave systems will then help push a cold front through our area by midweek, next week, with rain chances next Tuesday followed by a little cooler air. Stay tuned to a NOAA Weather Alert Radio for weather updates.
