Sunday September 6th… Dear Diary. The main purpose of this ongoing blog will be to track United States extreme or record temperatures related to climate change. Any reports I see of ETs will be listed below the main topic of the day. I’ll refer to extreme or record temperatures as ETs (not extraterrestrials).😉
Main Topic: Notes On Heatwave Chort And The West From Sunday
Dear Diary. With the explosion of California’s Creek fire from Saturday, in which some injuries have been reported, our western heatwave we’ve named Chort has seriously become a major climate news item and will continue to do so through early this week:
#Heatwave #Chort will remain at CAT4 status on #LaborDay Monday with southwestern maxes near all-time September records and more deadly conflagrations, such as the #CreekFire possible. A near record #cold air mass will make its presence known in the northern Rockies. pic.twitter.com/q015VhfI8P

National Weather Service advisories coming from the West look insane, with extreme heat being warned for right up to coastal areas. (in dark purple):

Lighter pink areas have fire watches. It’s very interesting that in Montana snow advisories are right next to fire advisories…another reason why this weather pattern is so unusual.
Today let’s just see notes from experts on this deadly weather pattern. Hopefully the public can pick up on some of this to get out of harms way. Here are more notes from experts on this developing deadly western situation:
Rarely do you see climate change mentioned in back to back stories on network news. It was tonight on @CBSNews by @JonVigliotti on California wildfires and yours truly on the #heatwave https://t.co/KivgwrLriu

Incredibly, this slipped in "under the radar" due to the more acute short-term wildfire crisis: 2020 has now eclipsed 2018 for the most acres burned in California in a single year during modern era (2,094,955 acres), & "offshore wind" season has not even arrived yet.#CAwx #CAfire pic.twitter.com/cP6cUYGHBq

A sobering thought: only thing stopping a number of California cities from hitting new all-time record high temperatures Sun may be dense pall of smoke from explosively growing wildfires. Also, I expect CA to set new record for acres burned in modern era by…Monday.#CAwx #CAfire https://t.co/J6zgmRF4qv
