I can remember this happening. Have a look at the charts for the first
few days of February, 1991.

Aah, the good ol'days! Can't see it happening this time. This current "cold
snap" has barely made zero even at night. I would have called this normal
winter weather once. Still at least I saw some snow today - for the third
year running.

But you wouldn't expect anything extreme at this stage. We haven't yet
started to draw in air from the continent. Even if/when we do, it is
likely to take some days for it to get really cold here, since northern
Europe temperatures aren't very low at present. However someone
mentioned in another thread that large areas of Europe now seem to be
covered, so Europe could start to cool down quite rapidly.
