90F/32C Degree Days Less & Less in U.S (hottest, warmest)

[Cambium]

VERY interesting... Based on data until July 23rd looks like there's been less and less 90°F days in the U.S.

I wonder how it looks the entire year or Summer only


“The frequency of 90 degree days in the US has been plummeting for 80 years"

So far, “2014 has had the lowest frequency of 90 degree days through July 23 on record.”

The only other year which came close was 1992, and that was due to dust in the atmosphere from Mt Pinatubo."

Coolest Summer On Record In The*United States

Doesn't really mean anything at all. It could be due to increased rainfall and humidity. What is the trend in mean temperatures? In Saskatchewan, we have seen fewer hot days and generally wetter summers (with stable mean temps.) but winters have been steadily warming.

It means there were more 90s in the past for the 1st half of summer and we've been steadily declining past 8 decades..

Like I said though, I'm curious what it shows after the 23rd.

Yes, but that could be a sign of warming or cooling. One would need to see the trend in mean temperatures across the entire year to determine where it's headed.
For example, we have our hottest days in mid-late August, a relatively cool time of the summer. During the warmest period of the summer, hot days are less common.

Surely not the case here

Not the case here in Oklahoma either. Year before last we broke a record for having over 100 degree weather for more than a month every single blasted day. It hasn't been that bad this year but the weatherman said last night to get ready for the hottest days, coming up.

We so rarely get rain where I live, and when it does rain, it's only for a few minutes, usually, so when that event occurs, we go out and look at it like some people would look at a UFO if they saw one. Looking up with our mouths open in shock! Kinda like this .

Nope, its not.. Looks like precip is pretty level since 1930 averaging about 15" from May 1 to July 31 period.

Yes, more proof that we are going into an ice age, lol.

Perhaps you missed these articles:

June 2014 warmest on record
June 2014 was Earth’s warmest on record as ocean temperatures surged

First half of 2014 third-warmest on record globally
2014 3rd warmest globally, Minnesota coolest on earth | Updraft | Minnesota Public Radio News

Statistics on the number of hot days in the US don't really tell you anything except that extremes are being moderated in a small piece of the globe.

And it is not uniform across the US. I just checked Philly.

1931-60 23
1941-70 23
1951-80 22
1961-90 22
1971-00 26
1981-10 27

Looks like a clear trend up for Philly.
