Huge snow drifts with continued cold and strong winds have led to scores of homes being cut off this weekend in what’s turned out to be the heaviest March snowfall since 1979.
At Bradford Lister Park, an official Met Office station, 20cms of snow (8 inches) was recorded, with much larger drifts.
Over the Pennines, accurately measuring how much snow has fallen has proved to be very difficult because of the strong easterly wind.
In many places drifts have reached more than 10 feet deep.
We have to go back to March 1979 for a comparable snow event.
In Bradford, this weekend’s snow was the deepest since ’79, when 28cms (11 inches) was recorded; that year in Huddersfield it snowed non-stop for 41 hours, with 15 inches of level snow reported.

Significant snowfall is expected across parts of the UK on Friday and into the weekend, as mild air once again tries and fails to dislodge the relentlessly cold air that has been such a feature of the weather of late.
Parts of Wales, the Midlands and western parts of Northern England are likely to be worst affected.
For our region, by the end of tonight, snow will be affecting many parts of West and South Yorkshire, and more western parts of North Yorkshire, lasting on and off into the weekend - with Pennine areas most at risk.
Further east, sleet and snow will be patchy in nature at least at first, but with more persistent snow possible later Friday and into Saturday
Significant accumulations are expected over the Pennines, and possibly across some lower levels too, leading to a real risk of disruption.

It was autumn 2009 when I first started writing my BBC Weather and Climate blog.
My initial articles created huge interest around the world. They aimed to highlight the fact that global temperatures had levelled off at elevated levels, despite ever rising levels of greenhouse gases, a situation which remains unchanged nearly four years later.
At the time there seemed to be a reluctance to acknowledge such a levelling off in global temperatures, although this is no longer the case.
But Dr Kevin E Trenberth of University Corporation for Atmospheric Research (UCAR) was one climate scientist at the time who did acknowledge this apparent lack of warming in surface temperature observations.
It’s now described as the issue of ‘missing energy’ – namely with rising levels of greenhouse gases, where has the expected extra global warmth, which basic physical laws predict, gone?
It is, for obvious reasons, a subject of great interest to readers of this blog, and I thought a recent article I read would be of interest.

A new global temperature forecast published by the Met Office, through to 2017, has scaled back projections of the amount of warming they expect compared with previous estimates.
The new projection can be seen below with more details on the Met Office website.
I have written several times in the last few years on the subject of Met Office global temperature predictions, and how they have been regularly too warm.
In the 12 years to 2011, 11 out of 12 forecasts were too high - and although all projections were within the stated margin of error, none were colder than expected.
One of their most high profile forecasts came in late 2009, coinciding with the Copenhagen climate conference.
It stated that half the years between 2010 and 2015 would be hotter than the hottest year on record, which I wrote about on my blog.

2012 averaged across the UK was the second wettest on record in data which stretches back to 1910, falling short of a new record by only 6.6mm.
In total 1330.7mm fell last year, compared with the average of 1154mm. A new record has been set across England and Wales with 1205mm of rain.
And locally new records have been set for Yorkshire, with 1230.8mm (136% of average) and Lincolnshire with 841.3mm (135% of average). It's been a remarkable run of wet years in the UK since 1998; 6 years are now in the top 10 wettest - 1998, 1999, 2000, 2002, 2008 & 2012.
Even more striking are figures based on the much longer England and Wales rainfall data series, first started in 1766. 2012 is provisionally in the top 4 wettest in 246 years (the other years being 2000, 1872 & 1786).

We may have to get used to wet summers like we've seen recently across the UK, according Dr Edward Hanna from Sheffield University in an interview which you can see on Inside Out and Look North tonight.
According to Dr Hanna and an international team of scientists, melting summer Arctic ice may be weakening the jet stream, leading it to meander and become slow moving.
This effectively means that weather patterns become locked in for long periods of time.
The jet stream is a ribbon of strong winds high up in the atmosphere, a result of the temperature contrast between northern latitudes towards the Arctic, and latitudes further south.
Because the Arctic is warming faster than any other region on earth, this temperature contrast is getting weaker, leading to a less powerful jet stream in summer.

There is now growing consensus between most weather computer models that cold air from the east is likely to spread across Britain next week.
If so, it will be the first time since March that high pressure has properly dominated our weather, and will end a long sequence of at times record breaking wet weather.
And it looks to be a classic winter-time set up, with a powerful anticyclone developing across Scandinavia and into western Russia, pulling in cold easterly winds across a large part of the country, hence the old saying 'the beast from the east'.
The diagram below is what's known as an 'ensemble mean' from the ECMWF model for the middle of next week.
The computer program is run 51 times, each time with slightly different starting conditions.
The solutions are then compared, and give forecasters an indication as to how likely a particular outcome is.

A welcome change to drier but colder weather is likely as we head through this week following heavy rainfall since Saturday night which is once again testing flood defences across the county.
November is continuing a remarkable run of wet weather, becoming the 8th successive month where rainfall has been above average, a sequence which began in April.....
...Through this week somewhat colder air is expected to spread southwards as pressure starts to rise.
This will result in weather systems being 'blocked' from moving eastwards across the country, at least in the short term.
The good news is that this means weather conditions will become much drier generally, although showers are still expected more especially in eastern areas exposed to the northerly breeze.

Those of us with a keen interest in the weather can't fail to have noticed yet another headline in the Express this weekend, claiming this winter would be the coldest in 100 years, which you can see here.
Wherever I went this weekend, I've been stopped in the street by people asking me when the awful weather is likely to hit, whether they should buy winter tyres for the car, or go ahead with a planned visit to relatives at Christmas.
The headline in the Express came courtesy of little known 'Exacta Weather', a tiny private weather company, which bases its forecasts on, amongst other things, variations in solar output.
But the headline this weekend is almost identical to the one from this time last year, in which the same 'Exacta Weather' forecasted severe wintry conditions throughout last winter, leading to yet another front page headline in the Express.
In the end, last winter was milder than average.
Exacta Weather is by no means the only company to issue such forecasts.

Sudden stratospheric warming (SSW) has been the 'in' topic in meteorological circles in the last couple of years, ever since the severe winter of 2009/2010 in which December was the coldest since the late 19th century.
SSW is linked to sudden large increases in temperature over a few days in the stratosphere over the Arctic.
This temperature change cause winds to reverse their normal direction.
For some time, forecasters have noted that a sudden weakening in high altitude winds in the stratosphere was often followed in winter by blocking surface weather systems.
These blocking weather systems tend to bring much colder conditions across Europe and the UK from the east, stopping milder air pushing in from the Atlantic.
