Extreme Heat Alerts Across 20 States as Relief Slowly Approaches

It’s official—much of the eastern U.S., including the Ohio Valley, Deep South, Carolinas, and parts of southern New England, is experiencing a sizzling heat wave. With temperatures soaring into the 90s and around 100 degrees Fahrenheit, it’s safe to say that approximately 125 million people are feeling the heat. This heatwave is caused by an *intense heat dome* that has settled over the region.

Despite some signs of relief, the typical summer heat is expected to hang around for a bit longer. A cold front is gradually making its way south through the Great Lakes and New England, which will help reduce the overall intensity of the heat over the coming days. However, even as the heat dome starts to wane, this week’s temperatures will still be about 10 to 15 degrees above average for this time of year.

For those in the affected areas, especially in the Ohio Valley and Mid-Atlantic, the extreme heat risk ranks at a concerning Level 4 out of 4. With expected high temperatures hitting mid-90s to around 100 degrees this Wednesday, it’s critical to stay cool and hydrated.

As the week progresses, the core of the heat dome will shift toward the Southeast U.S.. By Thursday, many areas in the Midwest and Mid-Atlantic will experience a bit of relief. However, Friday will see a concentration of heat in the Ohio Valley, with the forecast suggesting a transition back to typical summer conditions afterward.
