I found even more interesting that in the US South a place like Mobile, AL on March 9th, 1932 had a high temp of 30F with the same sun angle you would have in Yorkshire on July 30th. Hmmm.
Why did you choose Mobile and that date? The lowest Max temp Mobile had was 36° on 3/3/1943. Where did you see 30 was the high? Another Reason why I ask is because there has to have been more times with that kind of max in March in the south. Maybe someone can point out another location and date. But curious where the 30 came from.

Thank the mid levels again for being so cold. Take a look at the 850mb temps at lunch time. Colder than -10°C in NYC. NW flow up there. Philly was -8°C at 850mb. Normal is about -2°C. Look at that surge of warmth in the plains at the mid levels..
Rest assure, the mid levels will warm up..
NWS Mt Holly perfectly explains this in their latest discussion.

THE AIRMASS IS FORECAST TO WARM ALOFT SOME AND THIS SHOULD TRANSLATE TO MILDER SURFACE TEMPERATURES /ALTHOUGH STILL BELOW AVERAGE/.
Today at lunch I thought about this very thing. Our lat is 39.9 and the max sun angle today at solar noon was 48.6 up from the horizon. This is the same as August 20th where you live or around Sept 27th here. The sun seems rather strong, yet so strange to feel these really cold temps.

Pure continental climates are sick when it comes to March, lol.
It is 15th August here.
I don't know how anyone would even consider that cold. I would personay find it so odd and find it hard to feel cold.
Looks rather bad, didn't know Paris had pollution issues, at least more than a typical large city.
Pictures are from Friday, the worst one. I could look at the sun about 1 hour before sunset and it disappeared behind the toxic cloud 15-20 minutes before reaching the horizon. No doubt the air quality was really bad, but all the haze wasn't due to human activities. Such severe smogs happen mostly in spring when pollen adds to the problem.
I think that getting rid of the diesel tax rebate and switching to a more realistic driving cycle would help curb the PM10 pollution issue. We have fiscal incitations to choose less CO2-emitting vehicles, but nothing is done (fiscality-wise) to promote less polluting cars. No kidding, this small car has a diesel version and people who do less than 15k km a year and drive mostly in the city will still buy it - though obviously the gas version for such small cars will be more popular. How does the particulate filter regenerates in this case? God only knows. The diesel version of this tiny hatch probably pollutes more than, say, a gas-fueled Camry - more PM, SO2 and NO2 - but since its mpg is very high, it benefits from a huge eco bonus.

I was in Paris for the weekend and the sky looked quite pristine on Sunday, but I've been told that I got lucky and arrived at the right time, and that it was quite hellish on Friday.
Yup Sunday had great weather. Blue dome and mostly clean air - not to mention the free public transit for those who don't have a monthly or yearly subscription. As usual, the emergency measures, like today's car use restictions, have been taken too late.
Took this pic on Sunday. The towers in the background are about 4 km away. Same pic on Friday they would barely be visible. The NW change on Friday night really helped improving visibility between Friday and Saturday.
