Having had a week of not so bitter weather with temps around 5C I was
expecting it to be colder today. So why, with 850 hPa indicating -8C
here,
sub 528 dam, is it 6C and raining in the showers?


Long fetch off a super warm North Sea below 850 hPa melting the
snowflakes
aloft. Sadly for you SE folk the days of sig. snow at low level are
getting
rarer, unless the North Sea cools down more again in winters, it will
remain
thus. At altitude, in places like Luton, snow will continue to occur
regularly but it will not be bitter. You are quickly becoming like the
south
coast whereby the only time you will get sig. snow is if the 1000-500 hPa
thickness falls below 516 DAM, or you get a more continental air fetch or
a
"special" synoptic setup like a slow moving front with a fetch off colder
land. Snow lovers need to gain latitude or altitude, preferably both.

Sorry :-(

Any idea on frequency, Will? I think December 2010 was considered a once
in 100 year event, whereas perhaps in the 1960s, it could be considered a
once in 15 year event.


No sorry, but Dec 2010 was very severe in the CET record.

Have you seen the snowfall in Villablino, Spain. Well over a metre. The
location is at over 1,000m

Wow that is some snow. Thanks.
