Critical fire weather conditions can be expected across the Front Range Foothills, South Park, I-25 Urban Corridor, and most of the eastern plains of Colorado Wednesday. The worst conditions can be expected from mid-late afternoon through the evening as southwest winds increase with gusts around 45 mph. That will combine with relative humidity values in the single digits to create conditions favorable for rapid wildfire spread. Avoid any activity that may produce a spark, and be ready to take swift action should a wildfire start closeby. Always follow instructions from local officials.
