Meteorologists warn week ahead in US will have dangerous temps: 'Heat is not to be played with'

A large, strong, and long-lasting heat dome will cause dangerous temperatures across most of the US Lower 48 states, with temperatures 15–25°F above normal for at least a week. The event threatens health risks, worsens wildfire conditions, and may break over 90 temperature records, including overnight highs. Meteorologists warn that prolonged heat without nighttime relief is particularly hazardous.
