Scorching weekend heat expected to hit 30+ million people in West with temps up to 130 degrees


All-time record high temperatures could be registered in cities such as Las Vegas and Sacramento.
More than 32 million people in the West live where an excessive heat warning or heat advisory is in effect.
June 2021 was the hottest June in 127 years of record-keeping and surpassed the record set in June 2016.


All-time record high temperatures could be registered in cities such as Las
Vegas and Sacramento, while notorious hot spot Death Valley has already
recorded a temperature only few degrees short of Earth's hottest ever
measured.

Forecasters with the National Weather Service said Death Valley hit 130
degrees Friday afternoon, but the observed high temperature was considered
preliminary and needs to be validated. Temperatures were creeping upward
again Saturday and hit 123 degrees in the early afternoon.


"These extreme temps are NO joke! Be mindful before heading outdoors this
weekend. Do not put yourself, nor first responders in danger!" the National
Weather Service Las Vegas said.

Las Vegas' all-time high is 117 degrees and Sacramento's is 115 degrees.

but it's a dry heat

i love dry heat. I remember when I used to live in melbourne, it would regularly hit 40+ in the summer, but it was so dry you wouldnt even sweat, it was lovely.

but it's a dry heat

yes 21.5% humidity giving a wet bulb of 22.54 C

humans cant exist in wet bulbs of 35 C and higher


"Humans’ ability to efficiently shed heat has enabled us to range over every continent, but a wet-bulb temperature (TW) of 35°C marks our upper physiological limit, and much lower values have serious health and productivity impacts. Climate models project the first 35°C TW occurrences by the mid-21st century. However, a comprehensive evaluation of weather station data shows that some coastal subtropical locations have already reported a TW of 35°C and that extreme humid heat overall has more than doubled in frequency since 1979. Recent exceedances of 35°C in global maximum sea surface temperature provide further support for the validity of these dangerously high TW values. We find the most extreme humid heat is highly localized in both space and time and is correspondingly substantially underestimated in reanalysis products. Our findings thus underscore the serious challenge posed by humid heat that is more intense than previously reported and increasingly severe."

yes, the heat truly felt different than whenever it is in 30C or 40C in my nation for example

i experienced this sort of heat, in Death Valley when we drove through that and stopped just for some sightseeing for a moment

also Vegas has had lots of hot weather many many decades, i can remember we could've dried our hair after shower on the balcony

Don’t jump down my throat, I’m only trying to help, but I think that you meant lightning, lightening is when you make something dark a bit lighter in colour.
