The National Weather Service says even with temps in the 70’s studies have shown that the temperature inside a parked vehicle can rapidly rise to a risky level for children, pets and even adults. It was expected to last until 7 p.m. Friday, according to the National Weather Service.

A heat dome, made of high-pressure air, is raising temperatures from Canada to Mexico affecting some 122 million Americans over an area stretching 830,000 square miles amid risky fires and thunderstorms.
Weather and government officials advised people to stay cool as the heat dome makes its way across the country.
A “heat dome” is sweeping across the United States this weekend, bringing prolonged sweltering temperatures, expected to reach 15 to 25 degrees Fahrenheit above what’s normal for this time of the year.
“However, even young and healthy individuals can succumb to the heat if one does not take appropriate precautions”, he added.
Though the term “heat dome” may be unfamiliar to many, it is not new. That combination means heat index values of over 100 degrees tomorrow afternoon in parts of the Pioneer Valley. High humidity caused by extremely warm water in the Gulf of Mexico will make the weather even more oppressive.
The water level is down significantly on many rivers and streams because of the warm temperatures and lack of rainfall.
Saturday is expected to be the worst day of the heat wave in Southern California with temperatures dropping very slightly Sunday and into Monday.
So the National Weather Service recommends that people stay indoors (preferably with serious air conditioning), limit strenuous activities and stay hydrated to keep from overheating.
He also said parents should take care not leave children alone in a vehicle, even if it’s just for a few minutes.
“It will still feel hot, but it won’t be quite as muggy [as Friday] because of the lower dew point temperatures”, said Alan Dunham, meteorologist with the National Weather Service in Taunton.

“At first signs of heat illness – dizziness, nausea, headaches, muscle cramps – move to a cooler place, rest a few minutes, then slowly drink a cool beverage”.
