The sprawling heat dome will shift its focus to the Southern and Central Plains this week, bringing summer-like heat back to the region. Temperatures will approach triple digits for nearly 30 million people by midweek.
Temperatures could climb 10 to 15 degrees above average for early September, while humidity pushes heat index values to 105 degrees or higher across parts of the eastern Plains and Heartland, including Oklahoma, Arkansas, Missouri and Mississippi.
EXTREME HEAT SAFETY: RECOGNIZING SIGNS OF HEAT ILLNESS AND HOW TO TREAT IT
Dew points will be in the 70s, meaning there is a very high amount of moisture in the air, which feels oppressive, heavy and sticky to the human body.
Nearly 45 million Americans are under Heat Advisories and Extreme Heat Warnings, which will remain in effect through Labor Day, including in St. Louis.
The heat is expected to intensify again Tuesday and Wednesday, when record highs could be possible from Dallas to St. Louis.
HOW EXTREME HEAT IS FORCING SCHOOL SYSTEMS TO ADAPT FOR BETTER QUALITY LEARNING
Several Southern Plains cities are already having their hottest year on record. Oklahoma City, Dallas and Houston are all currently ranked No. 1 for their warmest year to date.
The heat may linger into mid to late September, with the Climate Prediction Center highlighting the potential for above-average temperatures and drier-than-normal conditions across the region.
A heat dome is a persistent weather pattern that happens when strong, high-pressure systems trap hot air over a specific region, forming a lid or cap, according to the NOAA. Under high pressure, the air sinks to the surface, acting as a dome.
WHAT IS A HEAT DOME AND HOW CAN IT AFFECT YOU DURING THE SUMMER MONTHS?
Unbearable heat can have serious health risks as well, as extreme heat and humidity are one of the leading weather-related killers in the U.S., resulting in hundreds of deaths each year, according to the National Weather Service.
Heat domes can bring a serious risk of heat stroke, which occurs when the body can no longer control its temperature and the sweating mechanism fails to cool itself down.
WHAT IS THE HEAT INDEX AND WHY IS IT IMPORTANT TO YOUR HEALTH?
It is important to always check the forecast for heat warnings in your local area and be prepared before going outside in terms of drinking enough water, eating enough food and staying in the shade.
