Temperatures in the Las Vegas Valley are likely to break decades-old records Wednesday and Thursday, according to the National Weather Service.
McCarran International Airport was stuck at 111 most of Tuesday afternoon before jumping to an official high of 114, a degree short of the June 15 record set in 1940.
“We have not been this hot in 80 years,” weather service meteorologist Ashley Nickerson said. “If some people think it has been hot the past few days, it’s just going up from here.”
The mercury rose to 115 at North Las Vegas Airport while Henderson Executive Airport reached 114. Death Valley reached 121. Laughlin topped out at 118.
The forecast calls for a high of 115 for McCarran on Wednesday. The record for June 16 is 114, set in 1940.
Thursday and Friday forecasts are carbon copies, a high of 114 and an overnight low of 89. The record high is 113, set in 1940. If reached, the overnight lows would be records for the minimum temperature on those dates, 87 being the June 17 record (set in 2008) and 86 for June 18 (set in 2017).
There is a slight bit of limited relief in the forecast with a 10 percent chance of showers or thunderstorms Thursday and Friday afternoon.
“It will be brief if it comes, probably in the Spring Mountains and maybe the Sheep Range,” weather service meteorologist Andy Gorelow said. “It won’t be any big rainfall and won’t last long.”

An excessive heat warning for the valley began on Monday and is set to last through Saturday night, the weather service said, noting that it may be extended through Sunday.
Saturday’s high should drop to 113 with an overnight low of 89 while Sunday is pegged at 112 and 88.
The normal this time of year is 100.
The weather service said that since records began in 1937, there have been at least five instances when the high was at or above 113 for at least five days in a row. The longest stretch was in 1940, when high temperatures were at or above 113 for eight consecutive days.
The all-time high for Las Vegas is 117, last reached June 20, 2017.
Forecasters warn residents to stay inside as much as possible.
“Limit anything outdoors to early in the morning or in the evening after sunset,” Gorelow advised. “It will be extremely hot during the day and warm at night.”
The weather service also advised people to drink plenty of water and wear light, breathable clothing.
“Anyone overcome by heat should be moved to a cool and shaded location,” the warning said, advising a call to 911 for help for possible heat stroke victims.
The Southern Nevada Chapter of the American Red Cross has shared the following reminders:
■ Never leave children or pets alone in enclosed vehicles.
■ Use a buddy system when working in excessive heat and take frequent breaks if you must work outdoors.
■ Check on family, friends and neighbors who do not have air conditioning, spend much of their time alone or are more likely to be affected by the heat.
■ Check on animals frequently to ensure that they are not suffering from the heat.
Ryan Atkins, the NV Energy director of trading, analytics and operations, said that the heat wave will strain Las Vegas’ power grid, but the company does not expect any power outages.
“We’re well-equipped to handle these heat-type events,” he said.
Atkins advised customers who are trying to keep their power bill down to set thermostats at 78 or higher, keep blinds shut and avoid using the oven or other large appliances during the day.
