Extreme Temperature Diary- Sunday August 8th, 2021/ Main Topic: Two Heat Waves Slated To Affect The U.S. This Week

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: Two Heat Waves Slated To Affect The U.S. This Week

Dear Diary. For at least one day during this torrid summer there were no real heat issues across the United States:

It’s now early August, and climate change is exerting its influence across the planet, so you know that the mild temperature pattern can’t last long. Sure enough 500 millibar heights will be rising this week such that we experience two separate heat episodes across the United States. The stronger will be in the Pacific Northwest and resemble the historic, catastrophic and deadly CAT5 July event but probably will verify at my CAT3/4 dangerous level:

The other will occur east of the Rockies through the Plains into the Northeast where some locations such as Washington D.C. will see the hottest conditions so far this summer. The Southeast, which has been relatively mild thus summer, should see high heat and humidity from this event, although I doubt that many records will be set there. The Northeast has a better shot to set records. The event east of the Rockies will probably reach my dangerous CAT3 level.

One could make an argument that since we will see one giant heat dome across the country only one name should be used. I’ll consider that.

Ensembles are definitely pointing to a strong ridge from coast to coast with the most anomalous 500 millibar heights occurring in the Pacific Northwest by Friday:

By Thursday excessive heat will be on tap in just about every location except the Upper Midwest:

The new Pacific Northwest heatwave is particularly worrisome because it will extend into northern California, exacerbating the fire situation there, which has already been catastrophic.

As usual, I’ll be adding notes and article lengths in association with our potential Heatwave Eta as we go through this week.

Here are some “ET’s” reported from Sunday:

Here is some new July 2021 climatology:

Here is more climate and weather news from 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.)

Now here are some of today’s articles and notes on the horrid COVID-19 pandemic:
