It’s heating up in Las Vegas, but don’t be surprised. It’s June, after all.

The valley will see its longest 100-degree streak of the year this week, with temperatures topping the century mark every day through Saturday, said Chris Outler, senior meteorologist at the National Weather Service in Las Vegas.

This will be “the hottest spell of weather” the valley has experienced since March, when the historic heat dome baked the valley for two weeks, Outler said.

Today’s forecast high is 101; it’ll be 103 on Wednesday and Thursday. It was 99 on Monday at the airport. The last time Las Vegas saw a long stretch of 100-plus days was last August.

This week’s heat wave will not break any records, Outler said. And heat advisories/warnings are not expected to be issued.

Also, heat records won’t be broken in Death Valley National Park in eastern California, where temperatures are forecast to reach the 110-112 range this week.

Outler said a high-pressure system over the Southwest is causing the hot stretch, which is “not unusual” for early June, the start of climatological summer.

By Sunday, however, breezy conditions will return to the valley, with highs dropping to the seasonal mid-90s.
