It is going to cool a bit after a historic heat wave in the US Southwest

Phoenix and Central Valley Monsoons have Returned: More than 250 deaths are under investigation as heat-related deaths due to the first day of June 15

The highs in Las Vegas are forecast to slip as low as 94 (34.4 C) next Tuesday after a long spell of highs above 110 (43.3 C). Death Valley peaked at 128 (53.3 C) in mid-July, but will cool to 116 (46.7 C) in the fall.

Forecasters expect that by Monday, people in metro Phoenix will begin to see high temperatures fall under 110 degrees Fahrenheit (43.3 degrees Celsius) for the first time in a month.

Results from toxicological tests that can takes weeks or months after an autopsy is conducted could eventually result in many deaths listed as under investigation as heat associated being changed to confirmed.

More than 250 heat-associated deaths, including 25 in Arizona and Phoenix, have been confirmed and under investigation by the county’s public health department.

The fire department in the Phoenix suburb of Goodyear warned people that anyone can be at risk in the heat.

The new heat records being set this summer are just some of the extreme weather being seen around the U.S. this month, such as flash floods in Pennsylvania and parts of the Northeast.

The downward trend started Wednesday night, when Phoenix saw its first major monsoon storm since the traditional start of the season on June 15. While more than half of the greater Phoenix area saw no rainfall from that storm, some eastern suburbs were pummeled by high winds, swirling dust and localized downfalls of up to an inch (2.5 centimeters) of precipitation.

The overnight low this week at Phoenix Sky Harbor International Airport has fallen under 90 for the first time in 16 days giving people some relief from the heat.

A historic heat wave that peaked in the U.S Southwest in the middle of July is going to start tobate with the arrival of monsoon rains.

The heat is impacting animals, as well. A bear was cooling off in a Jacuzzi behind a home in Burbank on Friday. The police released a video of the animal in the neighborhood and warned people to lock up their food and garbage.

More than 1,300 people were told to leave their homes, and another 1,400 had to leave, as crews battled a blaze that charred three square miles in the community of Amigo, 60 miles northeast of San Diego. One firefighter was reported to have been injured in the so-called Bonny Fire, which authorities said was about 5% contained.

Gusty, late-afternoon winds were expected Saturday and Sunday in Santa Barbara County, posing an elevated risk of fire weather, the weather service in Los Angeles said. Hot, dry weather was also expected across nearby valleys, lower mountains and desert areas.

Also in California, triple-digit heat was expected in parts of the San Joaquin Valley from Saturday through Monday, according to the National Weather Service in Hanford, California.

There are increased chances on Sunday of cooling monsoon thunderstorms. Though wet weather can also bring damaging winds, blowing dust and the chance of flash flooding, the weather service warned. Sudden rains running off hard-baked surfaces can quickly fill normally dry washes.

But not on Saturday. The high temperature in the desert city with more than 1.6 million residents climbed past 110 F for the 30th straight day, the National Weather Service said. The previous record stretch of 110 F or above was for 18 days in 1974.
