For what little it is worth here are some temperatures for the same day in
1963 - taken from the posts I made on that winter.

Maxima: Oslo -6C, Stockholm 2C, Helsinki -1C

Minima Oslo -12C, Stockholm -9C, Helsinki -11C

That was with a high just west of Norway and NNE winds blowing over the
eastern and central parts of Scandinavia.

For what little its worth, just a thought Mike, by this time of that year,
wasn't the snow and cold ground already well established all over Europe and
the N Sea much colder so there would have been less warming of the surface
layers as the cold air came S Westwards?

Good point made there. Parts of Germany were a good deal colder than those
figures (-26C at one place in Poland) and one station in NW France was -13C
at 06z, both under clear skies and with snow covered ground. East coastal
areas of England, south of Yorkshire, were cloudy and below zero in a 20-30
knot SE wind. The "warmest" part of the UK was NE Scotland at around +5C
with the longer sea track.

The North Sea would indeed have been much colder than now.
