Heat Wave Trudges East on Wednesday
Key Points:
- A major heat wave affecting much of the Midwest is expanding eastward, threatening record-breaking high temperatures for millions more people.
- Over 160 million individuals are currently under extreme heat warnings or advisories, with many experiencing multiple consecutive days of severe heat alerts.
- The combination of triple-digit temperatures and high humidity is causing oppressive heat index levels, which better reflect the actual outdoor heat stress than temperature alone.
- Little relief from the intense heat is expected across much of the country until the weekend.
