Definitely not Palouse/Pacific Northwest in general levels. Usually the ridge sits in a location where the Dakotas get the brunt of the heat, but their state records are 120 and 121 and very difficult to break. In some runs, the ridge axis sits slightly farther east where the MN record of 115 could be threatened somewhere in the western part of the state, and even a few where MSP’s all timer of 108 could be threatened. But that’s the thing, that region has also had a bout with extreme heat this summer, but it was in early June so it wasn’t all time records being threatened. Seems like the pattern this summer is for the extreme, all time record heat to just bounce back and forth between the southwest, Pacific Northwest, and north central states and largely skip the rest of the country. Not so coincidentally, these are the areas most affected by drought.
