Snow Trends At Woburn–Update
By Paul Homewood
I looked at snowfall trends at Woburn last week, using the Snow Survey of Great Britain, which gave data from 1947 to 1992.
It showed the number of days when snow was lying.
I asked the Met Office if there was more recent data, and they sent me data up to 1998/9.
So now the graph looks like this:
We can see that the 1990s were snowier than most of the years in the 1970s and 80s. This rather spoils the theory that there is a long term trend to less snow.
It also reinforces the view that there was a one off shift at the end of the 1960s.
This raises the question as to whether the 1950s and 60s were actually the exception.
Unfortunately we don’t have data since 1997/8, but we can get a clue from the monthly maps produced by the Met Office, which show days of snow lying.
These run from Jan 2001 to Dec 2010.
For instance, Jan 2001. Woburn is approximately circled.

The map works on bandings, but if we assume mid range, for instance 1 to 4 = 2.5, the new graph looks like this.
Note that there is no data for 2000. Also that the Met Office numbers from 1946 to 1999 are for snow seasons, beginning in October. My figures, collated from the maps, are in calendar years, as this allows me to maximise the number of years shown.
There seems to be little overall difference between the 1990s and 2000s. It is also apparent that we get a very snowy winter perhaps a couple of times every decade, but most years have five or less days with snow.
Certainly the last two winters have been unusually mild, but this is not exceptional in Woburn’s record. There were similar periods, for instance,1971-74, and later 1987-89.
Estimating numbers from the map is not ideal of course, but it is worth pointing out that Woburn is a genuinely rural site, and would certainly see more snow than the urbanised areas in the region. Therefore, my numbers are more likely to be underestimated if anything.

Yet another excellently researched and factual article. Pity we don’t get such quality from the ‘warmist’ faction.
Just curious, Paul.
Why Woburn? Have I missed a post, or is that where you live?
Okay, stand easy!
Just found the earlier post, which you did link to.
Sorry.
Sorry!!!
I’ve just replied to your last comment!!
No. I came across the “Snow Survey of Great Britain” that used to be published each year upto 1992.
As the BBC had just run a programme about how snow had been declining in England (or specifically Kent) since the 1960s, I thought I would do some checks.
The only station in the South in the survey was Woburn
This is the first post:
It’s odd that one of the worst winters 1990/1991 doesn’t feature. What has long been a feature of our snowfall has been snow followed by rapid thawing when a warm front comes over. Often the same one that delivered the snow. The snow in December 1990 followed a few weeks of cold including freezing fog if I remember correctly. While the snow in the Midlands was deep, it barely touched Warrington.

The 2009/10 winter was unusual in that the cold followed the snow, which meant it was on the ground for a lot longer. It was the first time I remember snow sticking to vertical surfaces and did so for days. So all that needs to happen for snow to linger is for the high pressure to follow the snow, blocking the next waves of warm fronts.
Pictures on TV tonight showing huge dollops of global warming all over Europe, and Turkey. -43 in parts of Russia. This is just weather I suppose.
Maybe the atmospheric CO2 hasn’t fully mixed yet. 😉
Even the Biased Broadcasting Company (World Sevice and R4) have been reporting the cold over Russia this morning,

Tonight’s weather forecast is for the UK to get very cold by later in the week. It will be interesting to see how our renewables cope. Grid Watch shows just how little the current Wind contribution is (1.5 Gw). Will we see the first power shortages this week? If so let’s hope it acts as a wake up call.
In all this remember that it doesn’t have to snow to be cold. In my youth I can remember a February half term where it had snowed just before but then remained below freezing for every day of the week’s holiday. It made the snow useless for snow balls. There was no additional snow as high pressure sat over us for that spell.
In the winter of 1962/3 I was doing some research into a heronry at Newton Park College, near Bath. Since 1961 the population was decimated. Seven nests were occupied in 1963 compared with the seventy previously. Kingfishers were terribly affected too. When, at term end, I returned to the family home near Evesham,market garden friends told me of pulling dead pigeons from sprout stems to which they had been frozen . For some time before the weather had not been so extreme and it was to be some time after before it was nearly as cold. Wish the warmists could develop a sense of history and realise it has all happened before.
Another little quote I’ve picked-up over the years. If anyone knows the origin I would be most obliged to know…
