Heat Dome Brings Record Temperatures Across US, UK

A powerful heat dome is causing extreme and dangerous heat across much of the U.S., now affecting the Midwest, Northeast, and South, with states like Nebraska, Illinois, Wisconsin, and Iowa under advisories for potentially record-breaking temperatures and high humidity. Cities such as New York, Washington D.C., and New Orleans are expected to endure prolonged 90+ degree weather, while Memphis and other southern areas brace for another hot summer. Residents in northern Illinois and Iowa have been urged to take precautions, with community cooling centers likely to open and health officials emphasizing hydration and limited outdoor activity. In addition, the UK is experiencing a severe heatwave, prompting warnings from London medical officials to avoid the sun during peak hours to ease pressure on emergency services. The widespread and persistent heat is attributed to a high-pressure system and moisture from the Gulf of Mexico, and the event is expected to last into the following week. Elevated fire danger remains a concern in areas impacted by hot, dry, and windy conditions.
