The main purpose of this ongoing blog will be to track planetary 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: U.S. and Canadian Heatwave Amoco to Peak Today

Dear Diary. It’s interesting but worrisome that we have seen two similar upper air patterns that are in association with historic heatwaves across the Pacific Northwest in the last three years. Today Heatwave Amoco will peak after briefly attaining CAT3 status. Back in June 2021 we saw this pattern leading to CAT5 Heatwave Alpha, which killed hundreds of people from Oregon northward into British Columbia. That year I named heatwaves using the Greek alphabet:

Thankfully, extremely high 500 millibar heights for May won’t last too long. Note that our hear dome got only up to 591 decameters today while that of CAT5 Heatwave Alpha was about 598 decameters. Meteorologically, that’s quite a difference:

By Thursday our unfriendly heat dome will have collapsed, bit it will remain well above average temperature wise across the West:

In all seriousness, naming heatwaves this year after oil companies should highlight how they have contributed to the severity of these killing phenomena:

One reason that this heatwave gets a name is because of associated Canadian wildfires, lifting the thing go my dangerous, major CAT3 status:

In the space below I will be listing today’s records from Heatwave Amoco recorded later this Sunday.

(As usual, this will be a fluid post in which more information gets added during the day as it crosses my radar, crediting all who have put it on-line. Items will be archived on this site for posterity. In most instances click on the pictures of each tweet to see each article. The most noteworthy items will be listed first.)
