[Weather-history]

A plume of unusual warm air for the time of the year brought temperatures as high as 17.8°C for parts of England

 Weather-history Is that the 15C line over south-west England? Would love to know what that would produce today.

[Weather-history]

 LetItSnow! Yes, I think it might have got as high as +17°C 850hpa

Such a warm airmass for so early in the year, quite incredible. Still cannot find anything that warm for March and April, the earliest dates of something similar to that is 1st May 2005 with about 15C on a Herstmonceux ascent and 14th May 1992 with 16.2C on a Camborne ascent since records began in 1980.

I dare say that if that happened today ,they would blame climate change for it !

I doubt that very much, but you'll believe whatever you want to believe, eh?

 ANYWEATHER No, it'd pass almost completely without comment, since temperatures in the mid or even high teens are becoming increasingly common. We had a 17C already this February and in mid-February not at the end.

Well if the same set up occured today it would probably have warmer uppers and would break close the upper teens/low twenties at the surface instead of the mid teens and that indeed would be to blame on zah big cee cee!

 WYorksWeather well if the conditions had been just right and hadn't been cloudy it would have easily been a record warm day ....with temperatures above 20 c !☺

[WYorksWeather]

 ANYWEATHER That report of cloud seems to be limited to the Birmingham news article.

Since no day at any point in winter achieved 20C until 2019, what makes you think this day would have?

[ANYWEATHER]

 WYorksWeather with those synoptics back then,  the temperature would of passed 20c/68f . It's very plausible given the right conditions. ...☺

 ANYWEATHER You can say that about any day in any year: if this, if that = whatever we want. But facts are facts.
