A prolonged period of critical fire weather conditions will begin Sunday and continue through at least midweek. Conditions are expected to expand in coverage and intensify over time, with Tuesday likely bringing extreme fire weather conditions to the plains.
The period starts Sunday with a Red Flag Warning in effect for the eastern plains from 11 AM to 5 PM. Relative humidity values are expected to drop as low as 11%, combined with gusty southwest winds up to 40 mph.
These conditions will create a high risk for rapid fire growth and spread. Avoid any burning or outdoor activities that may cause sparks.
