Note that 7-day forecast is normally much more accurate than extended forecast for days 8,9 and 10. Since weather forecasting is based on complex calculations the accuracy of such forecast cannot be assured and you should check back closer to such dates. We make our best effort to provide accurate information in our Decatur Illinois weather report but do not guarantee accuracy of information.
