From CNN:
Intense winds across the Central United States this weekend are fueling critical fire danger across some states, and threatening power outages, tree damage, travel disruptions and blowing dust in others.
Low relative humidity is combining with high winds to create an extreme fire weather threat across the western half of the Southern and Central Plains – the highest risk level for fire weather. Across much of the Plains, over 10 million people were under red flag warnings, spanning nearly border to border. The widespread fire risk will persist across parts of the Central and Southern Plains through Sunday, driven by gusty, dry air and an ongoing drought. Any fires that start will be difficult to contain in the strong winds, the National Weather Service warned.
