Sunny skies and warmer temperatures under building high pressure to wrap up the weekend. Tomorrow will be even warmer across Central Illinois as warm air building in from the west brings maximum temperatures up above normal. Next chance for precipitation will accompany a wave moving through the region on Tuesday night and into Wednesday. Much of the precipitation is expected to be rain in the southern half of the area at the onset, and rain/snow possible in the north. However, the snow mix will increase as colder air works into the system as Wednesday progresses.
