Extreme Temperature Diary- Saturday May 23rd, 2020/ Main Topic: New Southwestern U.S. Heatwave

Saturday May 23rd… Dear Diary. The main purpose of this ongoing blog will be to track United States 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: New Southwestern U.S. Heatwave

Dear Diary. This Memorial Day holiday weekend is the traditional start of summer in the United States. Right on que we are seeing the first of what I fear to be many life threatening, stifling heat waves across the country. As we know, the chances for above climatological average summer heat is greatly increased because of carbon pollution.

The first of these heat waves is beginning across the southwestern U.S. where excessive heat watches have been posted by the National Weather Service:

The Desert Southwest is in this watch, which isn’t unusual, but San Francisco and the Sacramento Valley will get heat that residents are not accustomed to experience.

Here are some notes from the San Francisco Bay NWS Office on the coming heat:

P.S. To make matters worse a large fire started at a warehouse this morning at Fisherman’s Warf:

The smoke from this blaze is producing choking air around San Francisco, which I’m hoping will be temporary after the blaze is extinguished:

Here are more notes from NWS offices issuing heat watches for this coming week:

Whether or not we see widespread record heat from this episode remains to be seen, but certainly forecast 500 millibar heights lead me to believe that we will see at least a few of those “ET’s” being reported. Of course, I’ll be reporting on what transpires and perspires next week.

Here is more climate and weather news from Saturday:

(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:
