453 FNUS53 KILX 190833 FWFILX Fire Weather Planning Forecast for Central/Southeast Illinois National Weather Service Lincoln IL 333 AM CDT Tue Aug 19 2025 .DISCUSSION... Expect the wind direction to be variable today as a cold front moves from south to north across the region. Areas south of I-72 may see southwesterly winds to start the morning, then winds will shift to north-northwesterly as the front passes. Areas north of I-72 are more likely to see northwesterly winds through the day. Winds will be light (less than 10 mph), resulting in poor ventilation. Tomorrow, light north-northeasterly winds are expected area-wide. Hot and humid conditions continue today, especially south of I-70 where afternoon heat indices could climb as high as 105 degrees. After today, temperatures will return to near normal for the rest of the work week, with minimal precipitation chances until another cold front moves through over the weekend.
