North Texas Weather: Hot Temperatures Stick Around

A heat dome is a large area of high pressure that builds over a region, trapping hot air and creating extended periods of high temperatures. In North Texas, this phenomenon causes temperatures to remain elevated for several days, with the first triple-digit day of the year typically occurring around July 1st. During such conditions, humidity significantly increases the 'feels like' temperature, and thunderstorm activity is usually confined to specific geographic areas, often north of major river boundaries.
