Extreme Temperature Diary- Saturday May 6th, 2023/Main Topic: Will Current Canadian Warmth Lead to Very Hot Times Across the U.S.?

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: Will Current Canadian Warmth Lead to Very Hot Times Across the U.S.?

Dear Diary. Over the last few days, a heat wave has developed across portions of Canada. We can see this from this morning’s 500 millibar analysis and from the Climate Reanalyzer:

This heat has had consequences. Wildfires have broken out across Alberta:

There also have been a lot of reports of heat records that have been broken across Canada:

So, will this Canadian heat lead to very hot weather across the United States? In the world of weather, many meteorologists have teasingly described Canada as the United States’ air conditioner. During winter if Canada has colder than average conditions, Arctic high pressure usually moves into the U.S. producing frigid weather. During summer, cool Canadian high pressure systems sometimes roll into the U.S. breaking heat waves…especially during prior cooler decades before climate change started to happen in earnest. If Canada isn’t chilly, having above average temperatures, usually the U.S. follows suit. We can see hints of this about a week out from today on models:

Before Saturday we could be seeing record temperatures from the Pacific Northwest eastward into the Midwest with above average warmth developing across portions of the South.

Of course, throughout this coming week I’ll be reporting on any anomalous heat that develops across North America and elsewhere across the planet.

Here are some “ET’s” recorded from around the planet the last couple of days, their consequences, and some extreme temperature outlooks, as well as any extreme precipitation reports:

Here is some more brand-new April 2023 climatology:

(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.)

And from the Weather Department:
