About 110 million people are under heat advisories in more than 20 states, from California to New England, as a severe heat wave that has scorched the south-central US spreads.

Many of these locations are anticipating high temperatures in the 90s or triple digits.

In Texas, where scorching temperatures have prompted record levels of electricity use, highs are once again predicted to reach 100 degrees.

The Southwest and the south-central US are forecasted to see the worst heat.

However, there are heat advisories in effect for some of the Ohio Valley and the Northeast, including New York City, Philadelphia, and Boston, and temperatures are anticipated to remain high at least through the weekend.

According to the Weather Prediction Center, Wednesday's high temperatures in much of the Northeast will be in the 80s to the mid-90s, but the humidity will cause the heat index, or how hot it will feel, to rise into the upper 90s and low 100s.

Jackie Bray, the commissioner of the state's homeland security and emergency services division, advised New Yorkers to remain inside in the coming days to avoid the "dangerous circumstances that can cause heat stress and disease."

A heat emergency has been proclaimed in Boston through Thursday, and Mayor Michelle Wu has stated that at least 12 community facilities will be available to anybody who wants to cool off.

At city parks and playgrounds, more than 50 splash pads would be accessible, she added.

The mayor declared, "It is obvious that a changing climate poses a risk to our health. I advise everyone to keep themselves safe and cool and to check on their neighbors throughout the week," as per CNN.

The governor of Connecticut turned on the state's severe heat protocol until Sunday, which will help, in part, guarantee the accessibility of cooling facilities.

From Tuesday at noon through Thursday at sunset, Philadelphia issued a "heat caution," advising residents to stay indoors from midday to five o'clock should utilize fans or air conditioners, the city advised CNN in an email.

Due to "very high temperatures," the city's public health department declared its first heat health emergency of 2022 on Wednesday, activating emergency services such as special field teams that do house visits and outreach for persons experiencing homelessness, the city stated in a press release.

Severe weather threat in Detroit

For Southeast Michigan, all severe weather alerts and watches have expired.

Even if the temperature barely drops into the late 70s, the area will dry out overnight.

Citizens can't rule out some patchy fog, but considering that the winds will still be blowing, don't expect it to be a major issue, as per Click on Detroit.

In the next days, there will be more sunlight, although some models are predicting a rain or two for Thursday.

Thursday and Friday will see lower-90s highs.

The weekend brings back the possibility of rain and a few storms, with Sunday having the highest prospects. People should expect a few rains on Saturday, but nothing that will cause an all-day washout.

The likelihood of thunderstorms, some of which can be strong to severe, increases significantly on Sunday.

Beyond that, the heat will start to subside a little bit.

Through Saturday, highs are in the 90s, but early the next week, the area will "cool" off a bit with highs in the lower to middle 80s.

It appears that this storm will occur between 3 and 6 p.m., with sporadic showers across Metro Detroit beginning about 4 p.m.

A "cold front" that sent these storms our way doesn't actually indicate that it will get cooler. The forecast for Thursday's high is for a "chilly" 89, which is only 2 degrees colder than Wednesday.

As one might expect, the weekend picture is still a little hazy, with Sunday having the highest likelihood of a storm.
