I never would've imagine a city like Seattle would shatter Atlanta's all-time high by the time their historic heat wave is over. Whether or not someone can attribute this to climate change, it's still terrifying to think about. Record cold temperatures in the heartland and record hot temperatures in the west. The year of extreme weather without a doubt. Makes me wonder if the trend may continue with tropical cyclones.

Meanwhile, the SE has largely had an average year.

I'm expecting 120F temps in Atlanta by August.
 
I’m watching if anywhere ends up hitting 120 in Canada , Ashcroft has 122 on google weather . Almost certainly too high but I hope it happens!

Hopefully not! This is already way beyond very dangerous.

1 PM PDT vs 24 hours ago:

Portland 104 (+11)
SeaTac 96 (+4)
Pendleton 106 (+5)
Walla Walls 106 (+5)
Spokane 98 (+5)
Yakima 102 (+2)

Gonna be a really long one when we have 100 degree weather from July 17 - October 1. ?

We're heading for nothing of the sort imo. The drought pattern in the US (which supports ridging to the west and north and troughing/western extension of Bermuda High in the SE along with model forecasts and persistence suggests a very good chance at no 100s in Nashville this summer (hasn't been any since 2012) with continued near normal temps/near to above normal rainfall for most/humid not dry imo:

Also the end of the LaNina and moving into neutral ENSO will support an active STJ as we move into late summer which would provide more cloud cover and higher dewpoints. I mentioned the other day that while the heat out west should release east at some point, it shouldn’t be nearly as intense and I don’t think we’ll see any long drawn out heat waves in the southeast… perhaps one or two 4-6 day periods with widespread 95-100 temperatures, but even 4-6 might be too long. Other than that, to me it looks like we see temperatures predominantly close to averages.
 
If Portland can hit 115, Atlanta can hit 120. Right ?

Portland has a really dry semi-arid desert and tall mountains(which further aids in descending warming air) to the east. It's also in a valley where heat can pool. It's near meteorologically impossible for Atlanta and the rest of the SE to get temperatures that hot.

Fun fact....Minneapolis has recorded a far higher record high temperature(115 degrees) than any southeastern city. Turns out having large bodies of water to your south/southwest and to your east helps moderate massive heatwaves.
