Las Vegas is hit by never-ending historic 120F heatwave as clip shows everyday objects melting in blistering Sin City

Las Vegas and the American West have been hit with a record breaking heatwave that has put millions under excessive heat warnings.

Dozens of locations across the West tied or broke previous heat records over the weekend and are expected to keep doing so all week. 

Forecasters say that Las Vegas will likely hit a record fifth straight day above 115 F on Wednesday following a week of unprecedented heat. 

On Tuesday, Sin City flirted again with the all-time temperature record of 120 F reached on Sunday, but settled for a new daily mark of 119 F that smashed the old one of 116 F set for the date in 2021.

'This is the most extreme heat wave in the history of record-keeping in Las Vegas since 1937,' said meteorologist John Adair, a veteran of three decades at the National Weather Service office in southern Nevada. 

Las Vegas experienced record breaking 120 F temperatures on Sunday and has experienced four straight days above 115 F

Tuesday's high temperature tied the mark of four straight days above 115 F set in July 2005, and experts believe this heatwave could extend through Friday. 

A very strong high pressure center is forecast to meander over southern Nevada the next couple days, pushing the sweltering temperatures to last at least through Friday, according to the National Weather Service.

An excessive heat warning is in effect through 11 p.m. PT on Friday due to dangerously hot conditions for an unusually long period.

'Yeah, I’m done with Vegas. I’m done with this heat. I’m ready to move back to California next week,' Candy Fuller, a 25-year Las Vegas resident told FOX5.

'I can’t handle this hot weather anymore. This is the first time it’s ever been like this.'

'You never really get used to it. It feels like every summer it gets hotter,' said 35-year Las Vegas resident Michael Peetz.

'It’s hot. It gets hot, really. Like my mother says, she says stay hydrated, always drink water, buy lots of water, so I’ve been doing that lately. I always wear sunblock as much as I can, I go inside to cool off.'

Two Las Vegas influencers demonstrated just how hot the scorching temperatures are by making s'mores with their car.

The duo roasted marshmallows on their car antenna and melted chocolate on the dashboard.

'Nice and gooey -  oh they're actually hot,' the woman said as she pulled the marshmallows off and assembled her treat.

They recorded a 30 minute time lapse that showed the colorful crayons melting on to canvases and creating art.

With the excessive heat warning in a effect through Friday, the weather service advised residents to stay hydrated and provide plenty of shade and water for their pets.

'When you got to wait in this heat, it’s not fun. If there’s no shade at the bus stop itself, I go into a local business inside somewhere close by, and I wait for the bus like that,' bus passenger Cris Pena told the local news station.

'Gotta stay hydrated so I don’t pass out. It’s tough. This heat is not good for anybody.'
