Saturday May 26th… 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:
Very Odd Weather Climate Change Clues (Mekunu)
Besides extreme changes in temperature nature leaves weather clues indicating that the climate is changing. One of the most obvious would be tropical cyclones happening out of season or in odd places. Last year we saw a hurricane, Ophelia, affect Ireland in mid October:
(Image from Wikipedia) Ophelia was the most eastern major hurricane in the Atlantic basin record.
This year in the Gulf of Oman Mekunu is raising eyebrows. It’s not out of the physical, meteorological realm of possibility that both Ophelia and Mekunu could have occurred in the same geographical locations and produced the same effects say in the 1960s, but a warmer world increases the likelihood for odd storms to crank in odd places and at unusual times of the year. In the case of Mekunu near the Arabian peninsula MIT has already produced a study in 2015 saying such:

The article title:
“Grey swan” cyclones predicted to be more frequent and intense. Study finds some coastal regions may face a risk of unprecedented storm surge in the next century.
So just how rare and unprecedented was Mekunu? Eric Holthaus has been blogging on the system putting it into perspective:
One of the strongest cyclones ever to hit Oman — equivalent of a Category 3 hurricane. Landfall in a few hours. #MekunuCyclonehttps://twitter.com/IrishEagle/status/1000063632191950848 …
Mekunu is about 12 hours from a direct hit on Salalah, Oman — a city of 200,000 people. Sustained winds currently estimated at 115mph (185kph). About 15 inches (400mm) of total rainfall expected — five years’ worth.pic.twitter.com/Z11mnSRooH
In the past 120 yrs, just 5 hurricane-strength cyclones have made landfall in Oman—1898, 1959, 2007, 2010—and today. (Chapala, in 2015, was the last to hit the Arabian Peninsula—and the only one ever to hit Yemen) So… 6 total in this part of the world, 4 in the past 11 years.

#Salalah reported 249.4 mm (9.82″) of rain from Cyclone #Mekunu during the 24 hrs ending at 4 AM Sat local time. That’s nearly twice the annual average. Even heavier rains no doubt fell across nearby mountainsides. Still raining @ 7 AM. http://ogimet.com/cgi-bin/gsynres?lang=en&ind=41316&ndays=30&ano=2018&mes=05&day=26&hora=00&ord=REV&Send=Send …

For context, the historical long term average number of days per year over 100F is ~10.
3:58 PM: The high so far today at Waco has been 98 degrees. This ties the record high for May 26th previously set in 1904. #ctxwx
From the NWS office out of KC St. Joseph Mo( kstj) had our second warmest May temp in our recorded history of 102F this Saturday, ( the record is 103, in 1934 on May 30th) so we are earlier this year. ( We also had our coldest April in history, talk about a swing).
Thanks Nicholas. Hope you like the post I made on 5/21 involving your temperature “whiplash:” https://guyonclimate.com/2018/05/21/extreme-temperature-diary-may-21st-2018-topic-climate-change-whiplash/
Keep up the good work in the Plains + I hope you are enjoying your career.☺
Oh, I need to make an update, I was just giving them credit, my apologies, I wasn’t trying to say that I was working for the NWS, again my apologies. ( at one point I had aspirations, but calculus and finances said otherwise :P) have a good Sunday 🙂
