Key Messages
- Pleasant and dry fall weather will dominate central Illinois through the rest of the weekend and upcoming week.
- Temperatures briefly cool on Monday behind a dry cold front before a warming trend pushes highs back into the upper 70s and low 80s mid-to-late week.
- Prolonged dry conditions will allow drought conditions to develop or expand and spark heightened fire weather awareness during ongoing fall harvest activities, though generally light winds should mitigate widespread fire risk.
