Central US Remains Under Persistent Second Wave of Heat Dome, Reaching 110 Degrees for the Week

Meteorologists predicted weather this week, saying that a massive heat dome will spin like a giant wheel across the central US, with the most persistent extreme temperatures centered over the southern Plains and lower Mississippi Valley region.

Extreme temperatures will reach well into the 90 to 100 degrees in many parts of the central US covered by the heat dome; highs may reach the 110s at times.

A surge of 100-degree heat shifted from the Dakotas to Minnesota and northern Wisconsin on Monday as the giant wheel of heat continued to wobble.

Summer in the Icebox

The temperature in Minneapolis reached 101 degrees on Monday, June 20, which brought the city back to triple-digit temperatures for the first time since 2018.

On Sunday and Monday, International Falls, Minnesota, dubbed the "Icebox of the United States," experienced temperatures hotter than Miami.

On Sunday, International Falls had a high of 93 degrees, as Miami got 92 degrees.

According to Dean DeVore via CNN, an AccuWeather Senior Meteorologist, the second wave of the heat dome will shift as the week progresses, with the worst levels of both humidity and heat forecast for Tuesday and Wednesday in the Midwest.

On Tuesday, the extreme heat will shift southeastward, bringing temperatures in the upper 90s and low 100s to parts of Michigan, Wisconsin, Illinois, Indiana, Iowa, and Missouri.

At midweek, the excessive heat will continue to move southeastward.

On Wednesday, June 22, Nashville may set a new record high temperature of 100 degrees.

As the heat wave moves to the southeast, temperatures in parts of the Midwest will cool off with the help of thunderstorms and showers as the week advances.

In Minneapolis, high temperatures will decline to the upper 80s on Tuesday and the mid-80s the next day.

By Wednesday, Chicago's afternoon temperatures are anticipated to stay within 80-90 degrees for the rest of the week.

Typical 100's

Meanwhile, forecasters predict almost no change in day-to-day temperatures across much of the south-central region through the weekend, June 25 to June 26.

For the week, high temperatures will be five to 15 degrees above average.

In cities such as Dallas, Little Rock, Oklahoma City, Arkansas, and Shreveport, Louisiana, ordinary highs will range from 90 degrees to 100s each day.

By the end of the week, the heat dome is expected to rotate southwestward into the Mississippi Delta region, potentially setting new highs in the area.

High temperatures could rise by five to 10 degrees in Gulf Coast cities, including New Orleans.

Friday and Saturday could see the record highs of about 100 degrees.

Starting Thursday, highs of 100 degrees are expected in Houston, which will last until at least Sunday. Parts of the Plains and Midwest may see another wave of extreme weather by the end of the week, AccuWeather reported.

Over parts of the northern Plains and Upper Midwest, a more significant temperature reduction could occur from late this weekend to early into the next week, with highs returning to near average for a few days.

Most cool air and storms will be forced well to the west, north, and east of the region, so there will be no relief for much of the South Central states.
