The National Oceanic and Atmospheric Administration (NOAA) has released its spring 2026 weather outlook, predicting a significant heat dome effect across much of the United States. This weather phenomenon, characterized by a high-pressure system trapping hot air, is expected to cause above-normal temperatures, especially in the western U.S., the Plains, and parts of the South and Midwest. The forecast suggests that these regions will experience conditions similar to early summer, with drought conditions likely to worsen.
