Monday September 3rd… Dear Diary. The main purpose of this ongoing post 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)😊. Here is today’s main climate change related topic:
Warning Signs For Dangerous Tropical Season For U.S.
On this Labor Day morning I’m not liking what I’m seeing in association with the tropics from both a weather and climatological standpoint. Yesterday I wrote a post indicating how warm it will be over the eastern U.S. and Atlantic basin. This warmth will play a big role in the future of any organized tropical cyclones that potentially will make landfall in the U.S.
As expected Gordon has formed off the southwest coast of Florida and maybe undergoing rapid intensification due to low wind shear and above average sea surface temperatures. Let’s take a look at current messages in association with Gordon:
At 10:35 AM the center of Tropical Storm Gordon was over Cape Sable FL (on the southwest edge of the Everglades) about to enter the Gulf of Mexico. We’ll see what lat/lon NHC places #Gordon at 11 AM. pic.twitter.com/alSV092JCJ

5 pm Tropical Storm Gordon update. Gordon is currently forecast to become a category 1 hurricane prior to making landfall Tuesday evening along the central Gulf of Mexico coast. A Hurricane Warning has been issued from the mouth of the Pearl River to the Alabama-Florida border.
The official National Hurricane Center Track/Intensity forecast for Tropical Storm #Gordon. Southwest Alabama, Mississippi, and Louisiana residents: heed caution.
Tomorrow there will be a huge ridge near 597 decameters centered over the Mid-Atlantic area that will steer Gordon towards the northwest. This warm air aloft will also extend over Gordon helping to fuel the system. Unfortunately this 12Z Monday model run did not initialize Gordon well at all, not indicating low pressure or a closed center low at about 1009 millibars.
Now to Florence. Last nights European model indicated that this Cape Verde storm will intensify and threaten the East Coast next week:
For what it is worth today’s 12Z European model looks more threatening:
The developing ridge is so strong extending from the eastern U.S. into the Atlantic that the European model’s solution is quite plausible. Most Cape Verde systems that steer north of the Leeward Islands recurve out to sea being deflected by early fall troughs moving through the U.S. This may not be the case this season.
Atlantic Hurricane ECMWF model 10 day forecast update .This model is has changed. The ridge of high pressure to the North of the cyclone is steering it, to the U.S. East Coast.

Finally, the much anticipated El Nino has not formed yet, so wind shear across most of the Atlantic is lower than it would be had we seen development in August or earlier. We probably won’t see El Nino until October at the earliest.
All of these factors lead me to put up some warning flags for this season.

Tuesday our East Coast heat wave will be in full swing:
The best chances for below-normal temperatures during September 11th through 17th appear to be across the Pacific Northwest and Northern Rockies, with most other parts of the country seeing increased chances of temperatures being warmer than usual. http://www.cpc.ncep.noaa.gov/products/predictions/814day/ …
(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.)
Here is today’s climate related news:
I highly recommend reading this linked article:
We all belong to one or more constituencies that can either support the status quo, or challenge it. These so-called “pillars of support” are our points of leverage. No matter what our passion or career, we all have some influence. Use it! https://mashable.com/2017/05/06/how-you-can-fight-climate-change/#n9hBRfi4hOqL …
And we have a Global Weirding episode about that popular myth!
