A recent pattern change has allowed stifling heat to build gradually across the southwestern United States. As the week beginning May 25, 2020, continues, meteorologists caution that the heat will further intensify over the region, which will allow numerous daily records from Sacramento to Phoenix to be challenged.
Temperatures began to climb on May 24, with some locations in the Sacramento Valley of California reaching 10 degrees Fahrenheit above normal.
Even in places where records are not set, anyone outside will need to stay hydrated and seek relief in an air-conditioned environment as much as possible.
