Record-breaking heat dome expected to bring dangerous temperatures to US south-west - The Guardian

The system stretches from the southwest into the south-central US, putting the South Plains squarely in the conversation. The National Weather Service flagged the scorching late-summer stretch as a potential health hazard, with overnight temperatures offering little relief from the daytime punishment.

For people in Lubbock, that combination of extreme highs and warm nights is the dangerous part. The body needs cooler overnight temperatures to recover from daytime heat stress, and when that window closes, heat-related illness risk climbs fast. Folks without reliable air conditioning, those who work outside, elderly neighbors, and anyone spending time in cars baking in a parking lot all face real risk.

Some record highs are forecast to be tied or broken before the heat dome finally loosens its grip. West Texas summers are no stranger to triple digits, but a sustained stretch at 110 to 115 degrees is a different category entirely.
