In Illinois, cleanup is continuing from a massive tornado that swept through the suburbs west of Chicago late Sunday night, damaging over a hundred homes and injuring several people, including a woman left in critical condition.

The storm came as a record-breaking late-spring heat wave exacerbated a devastating drought in the western U.S. The extreme weather fueled wildfires in Arizona, California, Colorado and Oregon.

In Northern California, smoke from the Willow Fire in Monterey County continues to bring hazy skies and poor air quality to the San Francisco Bay Area. Seven million people in six states were under red flag warnings, with meteorologists forecasting another heat wave next week.
