Those border stops have been there for decades now. I remember passing through them quite frequently in the early 90's.
Visit weatherunderground.com, or weatherbug that is used by the news outlets.
You can peruse the thousands of local weather stations and look for yourself. Most of them are calibrated with NWS standards. I' not giving you the link to my weather station(also calibrated) mostly because it will give the exact location where I live. If you find it, good for you. The data is there.
It's incredibly far off from a typical Phoenix July Day.
When you have that heat, with a dewpoint in the 80s, instead of the 30s or 40s like Phoenix, it makes a huge difference.
I have been in Phoenix in 115 heat. It felt downright comfortable compared to a midwest summer in the 90s, with high humidity(dewpoints in the low 80s).
That's neat.
But your inability to convert them on the fly, does not mean it is that hard for everyone. Personally, I have no problem switching back and forth between units of measurement. I was able to convert the OPs numbers on the fly, and compare them to my measurements in a different scale(the one they were physically measured in) with no problem at all. Your shortcomings are not the worlds problems, they are yours. Stop blaming others for your lack of ability.
The point was to succinctly point out the numbers. When I say 'fun stuff' I dont mean funny stuff. I mean since so many people have not taken this seriously at all, they must think it is a game. And that the last heatwave Chicago saw with temps in the low 100s for days, caused the deaths of hundreds and hundreds of people, barely over 15 years ago.
If temps ever got to 127F for days or weeks on end in Chicago, it would not be a stretch to say that tens of thousands of people would die as a result in one city alone. That is probably a conservative estimate.
Plus the temperature record is affected by inaccurate weather station readings that were once rural, but now are in the middle of expanding cities (heat zones). That skews the data and makes it unreliable.
Except the reverse happened in Chicago, where these records are being broken, and this story is about.
The station was at a core downtown location, then to a core airport slightly further away, until around 1980, when it was moved outside of the city core entirely, to O'Hare airport.
temperatures near the -10 Celsius
Now, as cold as you think that is, it is a warm night for a Chicago winter.
As I posted earlier, in some suburban areas of Chicago, it was 91F today. (that is 42 degrees above average, for nearly 10 days now)
For some perspective, if it was as much above average in Chicago in July as it currently is now, the daily high temperature would be 127F, with an overnight low of 94, for over a week.
Those temperatures are almost above the maximum globally recorded extremes for heat, ever, and certainly would be for Chicago by almost 20F.
Readings in SW suburban areas of Chicago reached 91F today.
Don't be silly, it won't be 200F in July.
If it was as much above normal in July, as it is currently in March here in Chicago, the daily high would be 127, with an overnight low of 94.
Fun stuff, isn't it?
