Summer is getting off to a sizzling start.
Oppressive heat will grip large parts of the US as temperatures surge to near triple digits across the Midwest and into the South on the first official day of summer, forecasters said Tuesday.
A large “heat ridge” — an area of high pressure — will make for sweltering conditions across the Great Lakes region, including in Chicago, where a high of 99 degrees is expected Tuesday and could surpass the record of 101 set in 1988, Fox Weather meteorologist Geoff Bansen told The Post.
Records in the upper 90s are also in jeopardy of falling in other major cities like St. Louis, Detroit and Nashville, Tennessee.
The heat will then move south Wednesday, descending on metro areas like Atlanta and Columbia, South Carolina, and parts of Tennessee, and into Florida and Texas, where triple-digit temps are expected on Thursday, Bansen said.
“The south-central and south are really going to bake right on through to the start of the weekend,” Bansen said, adding that residents from Texas to Florida and Georgia will feel the brunt of the oppressive heat now lingering in the Upper Midwest, Michigan and parts of the Ohio Valley.
Heat alerts were active in eight states Tuesday, Bansen said, including Kansas, Missouri, Iowa, Illinois, Indiana, Ohio, Michigan and Wisconsin — with more expected as the week continues.
The extreme heat may lead to stress on power grids in those areas, but relief is expected to come with a return to normal temperatures by the end of the weekend and into next week, Bansen said.
“This is certainly not going to help that situation,” Bansen said of record energy use expected by customers this week in parts of Arkansas, Louisiana, Mississippi and Texas.
About 70% of US residents will see temperatures in the 90s this week — with nearly 20% expected to endure triple-digit temps, CNN reported.
Several cities set new record highs over the weekend, including New Orleans, where the mercury hit 97 degrees, and in Mobile, Alabama, where it reached 101 on Saturday, CNN reported.
Heat-related illnesses are also a concern amid the steamy conditions. Anyone who works or ventures outside should wear loose clothing and stay hydrated as much as possible.
