Some big August numbers in the Western Australian Pilbara region today...Port Hedland 39.9c ! And 39.1c at Karratha, a full 3.7c above the previous August record !
Plenty of other record August record heat in the region today including Mardie, Onslow and Roebourne.
Roebourne Airports 39.5c is also 3.1c above the pre 2020 August record max temp at the site. ( which has been exceeded now on the last 5 consecutive days )
Oustanding late winter heat !
"Miserable" dew points (per WeatherSpark) are those which are 75+ F / 24+ C. In light of the first miserable dew points recorded in September in seven years, I decided to take a look at how often they occur on average where I live, using the last few years (2014-2019) as my sample. They're pretty much entirely confined to summer. The data is for Nashville, TN.
On average, from 2014-2019, there were 12.3 of these days per year.
June had an average of 1.7, 10 out of 74 days.
July had an average of 7.5, 45 out of 74 days.
Aug. had an average of 3.0, 18 out of 74 days.
Every one of them were between June 18 and August 26 except for October 10, 2017.
The frequency in September would probably be about 0.3 per year, and May about 0.03-0.05 (one every 20-35 years); I found one on May 31, 1998 as the most recent occurrence.
Spoiler
Days in 2014:
July: 2 (23, 27)
August: 5 (11, 19, 20, 24, 25)
Days in 2015:
June: 7 (18-19, 21, 23-26)
July: 17 (1-2, 7, 11-14, 17-23, 27-29)
Days in 2016:
July: 9 (4, 6-8, 19, 22-23, 25, 27)
August: 8 (2-3, 9-10, 16, 20, 25-26)
So we are 8 days into September and the Airport is running at 35.3c average max temp, a full 2.7c above the long term average for the month The record hot Septembers are in the last decade, 34.1c in 2017 and 34.0c in 2010
Sept 2017 had 8 days +35c, and 3 of those were +36c.
Sept 2010 also had 8 days +35c.
The next 7 days still have 34-36 in the forecast so the first half of Sept 2020 is shaping up to be extremely warm at the Airport
And today the Darwin Airport reached 37.0c... the Sept record is 37.7 in 1971.
"Rapid City, SD, (WFO) was 102°F on September 5th and had measurable snow on September 7th. This 2-day gap between 100°F and measurable snow breaks the U.S. record for any station (previously a questionable 3 days at Ardmore, SD, in Sept 1929)"
"Rapid City, SD, (WFO) was 102°F on September 5th and had measurable snow on September 7th. This 2-day gap between 100°F and measurable snow breaks the U.S. record for any station (previously a questionable 3 days at Ardmore, SD, in Sept 1929)"
Oklahoma City had a high of 56°F/13°C on September 9. This was their earliest sub 60°F/15.5°C high on record by four days, and it broke the daily record low maximum by 11°F/6°C!
The Panhandle got down to 33°F/0.5°C, the coldest it's ever gotten there that early. However, while snow was in the forecast, it failed to materialize. This link shows some more state cold records that were set.
I was looking at the Purple Air website map that shows current Air Quality Index (AQI). It gives an idea of how bad or good the air is, especially in places in the western USA where wildfires have been raging for several weeks. Most of the wildfires were started by lightening and amplified by wind and hot temps, so in a way they are weather related.
The AQI in Oregon Caves, OR, which is in southwest OR just north of CA is above 700. That means the smoke and particles are so thick, you practically need to chew while breathing. All of the big west coast metros from Canada to Mexico have "purple air" (bad AQI) at present. I've never seen anything like this, so I'll consider this an interesting weather related statistic.
Maximum heights of snow cover in Belgrade capital of Serbia in period 1949-2014. Record snow height in this period was 80 cm on February 3, 1962.
