available on wetterzentrale, but I guess quite a wide spread.

Of course the problem is, what cold air westwards, with Moscow in
meltdown it's going to take some time to cool down.

ISTR that in 1986 there was a very zonal spell in January, bringing mild
air as far as European Russia, so that when the wind turned to the east
towards the end of the month it took about five or six days before
really cold air reached the UK.
