Possibly not a record, but fairly unusual for mid-February, I would
have

Well, the good news is that this IS indeed normal when the UK is under
easterlies, à la this weekend.:-o :-) ;-)

Check the records. The SAME thing happened in 1963 AND, I think, 1947,
too. Likewise with Iceland, or at least the southern part of it.
