The far west of Cornwall http://www.turnstone-cottage.co.uk/1987Snow.pdf (I link to this at any excuse, it was probably the snowfall of the century in the far SW, certainly heavier than in 1963.)

Penzance had a maximum temperature of -1.1°C on both the 12th and 13th of January 1987 with a minimum of -9.9°C in between, but most of Cornwall was much colder with maxes between -3 and -6°C.

Incidentally your chart for 12:00 on the 12th shows that the temperature
at what looks like it might be Marseilles was -6C. I don't suppose that
happens often!

Actually John,more often that you might suppose. I read an article earlier this year, so I'll see if I can find it and post a link.
Prone to heavy snow sometimes as well.

Thanks, Scott. I see that on the coldest day, the 12th, Wanstead
struggled up to -5.5C, which must have made it one of the warmest places
in the south-eastern half of England.

In Cranleigh, we had a little snow on the Monday, I think it was, but it
didn't amount to much. We had to wait for overnight Tuesday/Wednesday
for serious snow, but then it certainly made up for lost time. On
Wednesday morning, the gritters must have done a remarkable job on the
roads, as traffic was moving - if slowly - on the B road that runs
through Cranleigh, and I was able to make the 8 mile journey to
Guildford Station. (It's lucky that Boris Johnson wasn't running the
buses.) But at the station, a railwayman was standing by the entrance
telling everyone: "There are no trains. We don't know when there will be
any trains. We advise you to go home." I managed to get a bus back to
Cranleigh, by which time the snow had just about stopped.

That is a nice example of regression with time. That B road in the
opposite direction (Cranleigh to Ockley) certainly wasn't treated in the
icy conditions of December 2010. I remember trying to cycle back to
Broadbridge Heath from Holmbury, heading for the relative safety of the
A29, and there were cars wheel spinning on the short sharp inclines
along that B road.

Can anyone provide a link which explains the meteorological synoptic
conditions which accompanied the onset of the severe cold, in particular
where the cold air was advected from. From the synoptic chart in your
link the cold air seems to be quite localised over the UK, northern
France, Germany and a little further east, but further east of that the
air is less cold. If it was a strong easterly wind advecting cold air
from eastern Europe I would expect the blue colours to extend all the
way east into Russia. It looks like it may have started off with
easterly advection of cold air, then a cold blob got pinched off due to
milder southerly winds, possibly due to a low pressure system over the
European mainland, then the cold blob continued to be advected west and
over the UK.

I was living on the 15th floor of a tower block in Mile End at the time.
The prolonged cold caused the main water riser into the block to freeze
so no one in nearly 400 flats (there were a pair of blocks) had running
water. It turned out to be possible to tap into the larger street main
with a stand-pipe. Presumably the constant use kept it running though
I'd have thought it would have to be removed at night. I don't recall
how long that lasted but it was more than a couple of days.

It may have helped that from Cranleigh to Guildford must get a lot more
traffic than the Cranleigh to Ockley stretch. Also there are only two
substantial hills, I think.

But I suspect that more money was available for treating the roads in
1987 than was the case by 2010. We used to get the roads treated on the
housing estate where I live, admittedly not before a fall but usually
not too long afterwards, but that doesn't happen anymore. The last three
hundred yards or so up to my house is a moderate upwards incline, and as
a result there was one occasion in December 2010 when conditions were
too bad for the milkman to get his cart up the hill to deliver my milk.
Apparently he made it round the lower part of the estate, and if I'd
only known that and at what time he would be round, I could have walked
down to collect my milk from him.

I've had rather the opposite experience here. During the first few years that
we lived here our road didn't get any ploughing or gritting, not even during
the very bad weather in Dec 2010. However, over the past 3-4 years the road has
been ploughed very soon after any significant snowfall and we've even had
treatment from a gritter on a few occasions. The main road through the village,
which is a bus route, is always well ploughed and gritted when necessary.

I suspect that the long spell between 1997 and 2008 (and to a lesser
extent you could say 1988-2008), when most winters were mild and snow
was rarely a problem down here, led to cutbacks in expenditure on road
clearance, and of course once expenditure has been cut it very rarely is
reinstated.

Click on Kartenarchiv in the top left box and proceed from there. It gives 500-mb heights rather than thicknesses but the source of the cold air is clear.
