More than 25 million people are worried about the heat and more than 50 daily high-temperature records could be broken over the weekend – including Death Valley, California, one of the hottest places on earth.
“Don’t underestimate the heat!” Heat is one of the deadliest weather hazards, so be sure to practice thermal safety this week, ”tweeted the Sacramento National Weather Service.
“Record high temperatures will be [felt] in parts of Texas on Wednesday and Thursday and an expansion in California on Friday, “the Weather Forecast Center said Wednesday morning.
The high pressure will create a heat dome over the western United States. The dome will capture any escaping radiation and send it back to earth as the sun’s rays continue to penetrate it.
This, combined with dry soils from extensive and long-term droughts, will allow temperatures to rise to record levels over parts of California and the southwest, with high temperatures from the 1990s to over 110 degrees on Friday, the Weather Forecast Center said. said.
Here is when and where the heat will be worst.
The heat the size of Texas leaves the state boiling
“Hot Again” is how the San Angelo National Weather Service began discussing its forecast this morning, as mercury will rise in West Central Texas on Wednesday and Thursday afternoons.
The high temperatures will break the age-old note this afternoon, and the high ones will intensify as the week progresses. The peak intensity is likely from Saturday to Monday, the San Angelo meteorological service said.

Big cities in Texas will have high temperatures above 100 degrees. Austin, San Antonio, Dallas and Houston are likely to reach the figure once, twice, maybe even three or more times before the week ends.
Temperatures above average this weekend are likely to put the Texas power grid to the test.
During a heat wave in the state last month, Texans were encouraged to save energy by raising thermostats to 78 degrees and refraining from using large appliances during rush hour.
First heat wave of the year for Las Vegas and Phoenix
As this weather pattern stays over Texas until and over the weekend, it will expand to Southern California, as well as Nevada and Arizona from Thursday to Friday.
The first event with excessive heat – level 4 of 4 in the experimental scale for danger of heat – for the season, is ahead of us, announced the office of the meteorological service in Phoenix.
“The first heat wave of the year has multiple climate zones threatening daily record highs and record low temperatures,” added the National Weather Service of Las Vegas.
Death Valley is expected to reach 121 on Friday. If that happens, it will break the daily record of 120 set in 1994.
Las Vegas will also flirt with daily records, with temperatures close to 109 on both Friday and Saturday.

“High temperatures will reach 110 degrees as early as this afternoon and are expected to reach between 110 and 115 degrees in the lower deserts by Friday and continue over the weekend,” said the Phoenix National Weather Service.
Low temperatures at night will also be close to record highs.
Las Vegas is forecast to fall to 84 degrees on Saturday morning, for example. The previous hot low temperature was 81 in 1996.
What makes this so dangerous is that when the temperatures stay so hot at night, your body does not relax from extremes.
The heat is expected to ease early next week, according to the Phoenix National Weather Service, with temperatures dropping to near-normal levels.
And the Las Vegas and Phoenix weather services also say Sunday may not be as hot as originally thought.
The interior of California will have a “high” heat risk
Similarly, in California, the worst will be Friday.
If you are on the coast of California, you will escape the heat. The interior of the country will not be so lucky.
“Trend in warming and drying with three-digit heat by the end of the week for the Central Valley,” said the Sacramento National Weather Service. “The hottest day will be Friday, with a little relief at night from the heat.”
The risk of heat will be high – level 3 of 4 – on Friday for most of inland California.
“Daytime temperatures can reach at least 100-105 ° in the valley on Friday, which in combination with the warm temperatures at night will lead to a high risk of heat exposure for the general public,” tweeted the Sacramento Meteorological Service.
All weather services have had similar heat safety messages with tips to protect against excessive heat: Try to avoid caffeine and alcohol, which can dehydrate the body. Instead, drink plenty of water and try to find an air conditioner.
Drought exacerbates this heat
The ongoing drought continues to plague the Southwest. And one of the many disadvantages of drought – and dry soil – is its impact on temperatures.
When there is no moisture in the soil or in the plants, there is no evaporation or evapotranspiration, both of which are cooling processes that add moisture to the air and stabilize the air temperature.
“In general, the drier the air, the easier it is to get to a high temperature,” Brian Jackson of the CNN Weather Forecast Center said. “When there is more humidity, the temperature can be suppressed.”
