A powerful early-season heat wave is sweeping across the Southwest and Texas, with temperatures expected to break records in several states.
A ‘heat dome’ – a high-pressure system trapping hot air – is causing widespread triple-digit heat, especially in central and southern Texas.
Cities like Austin, Dallas, San Antonio, and Houston may see highs approach 110°F by midweek.
The National Weather Service is warning of increased risk for heat-related illness, as many people are not yet acclimated to such extreme temperatures.
Scientists link this scorching start to summer to climate change, which continues to drive longer, more intense heat waves worldwide.
