Following an unusually warm May for the region, June is already off to a warm start for much of the south-central United States.

According to AccuWeather experts, Mother Nature is about to crank up the heat and throw areas of the region into blistering temperatures early next week, threatening numerous daily temperature records.

The nation's electrical infrastructure is under strain like never before, with officials warning that the rolling outages currently common in California and Texas might become considerably more prevalent when hot summer weather approaches.

Beginning Sunday, a northward change in the jet stream will allow abnormally hot air to pour out of Mexico and into parts of the South Central states and the Four Corners area.

Temperatures will be on the increase in areas ranging from New Mexico and Texas north into Colorado and Kansas by Sunday.

While temperatures will surge above average in several regions on Sunday, experts predict that the most severe component of this hot air will settle over a big expanse of Texas.

This unusually hot weather will continue for the rest of the week, with temperatures in several regions reaching triple digits.

Temperatures in Abilene, San Antonio, and Austin, Texas, are generally around 90 degrees Fahrenheit in early June, but are expected to rise beyond 100 degrees Fahrenheit Sunday through Tuesday.

Daily high-temperature records in Austin and San Antonio will be threatened for three days in a row.

Temperatures in locations like Abilene will reach 105 degrees Fahrenheit by Monday.

Temperatures in certain places in southern Texas along the border with Mexico will rise much higher.

On Monday, air temperatures in Laredo, Texas, roughly 150 miles southwest of San Antonio, will be near 110 degrees Fahrenheit.

The current prediction for the city on Monday is 108, which would tie the 2018 daily high.

During the warmest portion of the day, temperatures may rise slightly above the ambient temperature.

Heat-related ailments such as heat exhaustion and heatstroke will become more common when the heat wave spreads over Texas and southeastern New Mexico early next week.

Forecasters advise inhabitants in impacted regions to stay hydrated and, if possible, minimize their time outside during the warmest portion of the day.

Power grids will undergo stress again

A vast section of the Midwest, which has had reliable power for decades, is suddenly facing estimates that it may be unable to cope with a heat wave, as per The Washington post.

The regional system lacks the electricity required to power 3.7 million residences.

After a regional utility warned of impending blackouts, New Mexico's attorney general is prepared for "worst-case scenarios."

North Dakota authorities have urged the state to be prepared for rolling outages, Arkansas officials are planning emergency energy conservation measures, and Arizona power firms are already warning about next year.

While indicators of trouble with America's electricity infrastructure have been present for years, the recent warnings have astonished even those who have been sounding the alarm.

This is due to the fact that extreme weather caused by climate change, as well as the early retirement of fossil fuel facilities, has expedited the instability of the grid, which is already weakened by a lack of investment.
