Wednesday July 4th… 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 post related hot topic:
Historic U.S. Heat Wave Day Seven
Happy 4th. Yeah let me write that it is as hot as a firecracker for most of the country while everyone groans.😎 As I would contend due to carbon pollution the mid-summer holiday is becoming hotter across the country, and 7/4/2018 is a prime example. Dangerous heat is denoted by NWS watches and warnings here:
Extreme heat is hanging on for another day in the Northeast. The area of real estate of advisories in the Midwest has grown substantially over the last twenty four hours. We’re still anticipating historic heat over the Southwest by the end of this week, but temperature levels are already at dangerous levels. Tomorrow there will be more of the same in all three areas of the United States:
The good news here is that a front will put the kibosh on heat in the northern Plains, and maxes won’t be much above 95F in the Northeast.
Across the West I should also mention horrendous wildfires taking place because of ongoing drought and that added heat. Here is a new article:
Quoting from this article:
Nearly 60 large, active blazes are burning across the West, including nine in New Mexico and six each in Utah and California, according to the National Interagency Fire Center. So far this year, wildfires have burned 4,200 square miles in the United States, according to the fire center. That’s a bit below last year’s acreage to date — which included the beginning of California’s devastating fire season — but above the 10-year average of 3,600 square miles.
Authorities announced late Monday that a fire near Fort Garland, about 205 miles southwest of Denver, had destroyed 104 homes in a mountain housing development started by multimillionaire publisher Malcolm Forbes in the 1970s. The damage toll could rise because the burn area is still being surveyed.

Yesterday I mentioned that the extensive heat dome will retrograde to the west exacerbating heat there by this weekend, but allowing a front to bring relief to much of the East. What happens next week?
Instead of breaking down, the dome moves back towards the east quickly heating much of the Plains and perhaps the South:
Residents of Houston aren’t too pleased with this weather pattern, but for another reason. A disturbance rotating around the southern periphery of the mega ridge is producing yet another flood emergency for that soaked city. Perhaps climate change is turning southeast coastal Texas into a swamp? I’m beginning to think so:

But look at how swollen Buffalo Bayou is! These floodwaters have forced the cancelation of the @FreedomOverTX concerts. #IndependenceDayFlood #HoustonFlood

[Oppressive heat dome engulfs the Northeast — and it will spread west this weekend]
Excessive heat torched the British Isles late last week. The stifling heat caused roads and roofs to buckle, the Weather Channel reported, and resulted in multiple record highs:
- Scotland provisionally set its hottest temperature on record. The U.K. Met Office reported Motherwell, about 12 miles southeast of Glasgow, hit 91.8 degrees (33.2 Celsius) on June 28, passing the previous record of (32.9 Celsius) set in August 2003 at Greycrook. Additionally, Glasgow had its hottest day on record, hitting 89.4 degrees (31.9 Celsius).
- In Ireland, on June 28, Shannon hit 89.6 degrees (32 Celsius), its record.
- In Northern Ireland,
- Belfast hit 85.1 degrees (29.5 Celsius) on June 28, its record.
- Castlederg hit 86.2 degrees (30.1 Celsius) on June 29, its record
Eurasia
A large dome of high pressure, or heat dome, has persistently sat on top of Eurasia over the past week, resulting in some extraordinarily hot weather:
- Tbilisi, Georgia: On July 4, the capital city soared to 104.9 degrees (40.5 Celsius), its all-time record.
- Yerevan, Armenia: On July 2, the capital city soared to 107.6 degrees (42 Celsius), a record high for July and tying its record for any month.
- Several locations in southern Russia topped or matched their warmest June temperatures on record on the 28th.
