Early April heat wave worsens drought across western U.S.
A surge of early April heat is returning across the western U.S., pushing temperatures well above average and worsening ongoing drought conditions. Cities like Los Angeles, San Francisco and Phoenix could challenge record highs as a strong high-pressure system limits rainfall. The heat is also accelerating snowpack melt, raising long-term water concerns. Dry, windy conditions are increasing wildfire risks, especially in California. Relief may arrive later this week as cooler air and scattered rain return to parts of the region.
