Extreme Temperature Diary Sunday September 27th, 2020/ Main Topic: Bad News…Diablo And Santa Ana Winds To Kick Up In California Interacting With Heatwave Desdemona

Sunday September 27th… 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: Bad News…Diablo And Santa Ana Winds To Kick Up In California Interacting With Heatwave Desdemona

Dear Diary. Meteorological models have greatly improved over the past ten years. Our western heat wave dubbed Desdemona has been well advertised for a week. For about that length of time a tightening pressure gradient has been forecast for Monday, which will lead to gusty fall northerly Diabo winds in Northern California and easterly winds in Southern California. Unfortunately, these winds spell more high fire danger for a state suffering through the beginnings of rapid climate change.

We are already seeing problems in Northern California this Sunday:

Winds will start to gust across Southern California Monday morning:

These gusty winds will be interacting with temperatures in the 90s and 100s:

The good news here is that at least it’s late September, so readings won’t approach all-time record maxes recorded from Heatwave Chort from the first of this month. Also, the pressure gradient will lessen by Tuesday and Wednesday, so critical fire weather may last only a couple of days:

Near record heat probably won’t lessen until at least Friday since Desdemona’s heat dome won’t come down significantly until late this week:

In the space below I will add notes in association with either more fires or record heat reports from Sunday and Sunday night:

Yes it can still get cold across the planet. Here is a cold overseas “ET.”

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:
