"Record-Breaking Heatwave Sweeps Across US, Bringing Summer-Like Temperatures and Severe Weather Outlook"

Hundreds of temperature records could be shattered across the US this week as warm weather persists, with over 250 million Americans experiencing above-average temperatures. Cities like Dallas and St. Louis are set to reach unusually high temperatures, with some areas in Texas and Oklahoma expecting highs in the 80s and 90s. However, a cold front is expected to bring a cross-country storm, cooling temperatures and potentially leading to severe thunderstorms with hail, tornadoes, and damaging winds in the Midwest and Great Lakes regions.
