Extreme Temperature Diary- Tuesday June 22nd, 2021/ Main Topic: Heatwave Alpha Forecast To Build Into The Pacific Northwest

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: Heatwave Alpha Forecast To Build Into The Pacific Northwest

Dear Diary. Finally. The heat dome that set up over the Southwest relented enough to declare this on Monday:

As of this morning there were very few advisories for heat across the West except for fire potential in the heart of the drought, so I’ll lower the ranking of heatwave Alpha to that of a CAT1 for Tuesday:

So is it time to officially kill Aloha, letting the arbitrarily named system become part of meteorological history? Hardly. An appendage of the old 500 millibar ridge associated with Alpha will heat up and expand over the Pacific Northwest this weekend. Since we can physically see a connection between the old heat dome over the Southwest and a new ridge over the Pacific Northwest, the next spurt of heat will not get named Beta:

The next strong ridge over North America may actually end up being centered in southern British Columbia. A 597+ decameter ridge would be historically high for that area of the world.

It’s already warm enough in the Pacific Northwest to produce some records since the Southwest centered ridge extended as far north as Washington State. For example:

The National Weather Service is also anticipating a big resurgence of heat over the weekend with maybe a brief break from now through Thursday:

Just how hot will it get across the Pacific Northwest. Stay tuned on this blog for that information.

Today I will be adding notes about Heatwave Alpha and its associated effects in the space below:

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

(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:
