Not possible in London.. reached 19.6C in February before, although that was mid month so I guess 20-21C in exceptional circumstances is possible
It's also not possible here, 60 miles inland from the coast.
If you go up into the Cascades during an inversion then you will occasionally get highs 70F-80F (21C-27C), when average summer highs peak between 68F/20C and 75F/24C. This scenario just happened this past week.

Well, it is, kinda, possible to get 70 in London, but it would have to be a radical extreme record! If set up right though, lots of sunshine, consistent southerly wind for weeks, and towards the end of Feb, it could reach 22 degrees (somewhere in the low 70s for those USA nationals )...
I think that weather.com map is off a bit. The official high in Denver yesterday was 75, which they said was 2 degrees short of the record. It would have to be a very overcast, rainy day in Denver in the summer to have a high of 75. By June, our average highs are upper 70s, climbing into the 80s.
London's record high in both Dec and Jan is 63. Nowhere near the 74 avg of July and Aug. So, London does not make it.
But it could in Feb... The 11th of Feb would have approx the same amount of daylight hours and sunshine angle as Halloween. Last Halloween, Britain sore a record breaking high of 23.6C (about 74.5F), the previous record was just 20.0C (68F) - that's a whole 3.6C difference from the previous record... If that same situation happened in February, a 3.6C difference from record to record would mean the temp would make it to 23.2C (about 73.8F) - meaning Feb could reach summer temp values!

That's completely different. Halloween follows summer. The sea is much warmer, the ground is warmer, the continent is much warmer etc. February doesn't have the same advantages.
It's incredibly unlikely.
Completely impossible here, as there's no mountains or nearby places with warm air, and the sea is either open or frozen. Even hitting 10C is a huge stretch.
As I have mentioned before, it can and do happen along the Norwegian west coast. A lot of mountains, steep terrain, fjords, open sea to the west.
Sunndalsøra recorded 18.9C in February, warmer than the average high in June in that town.
Bergen has recorded 16.4C i December and 16.2C in January, about the same as avg high in early June. Glomfjord just north of the Arctic circle:15.2C in December and 15.1C in January, slightly warmer than the avg high in June there.

Yea, that is true dude... But I swear we have seen 23 degrees in early March during resent years?
Meaning thst very late Feb, could see summer max temps (min is a diff issue)
In fact there's another prob I thought - if we do have high pressure during winter, even if winds were southerly, we would most likely still have sub-zero nights considering the latitude in which were in?..
