Default [WR] More moderate snow in Kent

We know that Ron. What we're saying, and I can't believe you've never seen
it, that heavy snow, whacking big flakes, with air temp around 0.5C - 1.0C
is not only failing to settle on the ground but also on already lying snow.
(although last one is from Darren!). Air is often is above freezing when
snow settles. Still think it's under soil heating!

Anyway lets hope this next burst does better for whatever reason.

It never ceases to amaze me how many posts refer to 'it won't settle

because
it's too wet ! .No lads, it won't settle ,not because it's too wet but
because it's too warm !
It can pee down with rain for 12 hours at 2C,,but as soon as the temp

drops
to zero ,it freezes and then settles .Bloody obvious to me.....like saying
it's too cold to snow ,but we won't go there eh /

I know I'm getting boring but I'm sure most people are surprised it

hasn't
settled more!

It's a theme that's cropped up on some Web based message boards as well.

The only thing I can say for certain is that given heavy enough snow (of
the big fluffy flake sort), it *will* settle, even if the roads are
soaking wet after rain/melted snow. Until today the last time I saw that
in action was the snow event in January 2004, which started with a few
minutes of heavy rain which turned to heavy snow and promptly settled.

Other than that, there's got to be an obvious reason why the snow's

having
such trouble settling in this spell. I'd be tempted to say it's the
radiation absorbed during the day that's causing it to melt so quickly,
but that wouldn't apply to snow falling early in the day.

75 minutes of moderate snow with fairly large flakes has produced no more
accumulation - temperature 0.8C but RH at 89%. Don't know how the snow
last night managed to accumulate on the roads at all!

Jonathan, or anyone, do you have any information about
snowdepths over the East Kent Snowtrap (i.e. the North
Downs between Canterbury, Dover, Folkestone and
Ashford)? Someone told me that there was "about six
inches" this morning. That "about" worries me. If it was
the average of several measurements then fine, I'll
accept it, but if it was an estimate then I would divide by
two or three because people always grossly over-
estimate snow-depths.


Estimate :-O

Don't people have rulers ?
All mine are *measured*.

I first noticed this on Monday when there was a reasonable amount of sun,
then during the evening the first snow that gave a covering arrived.
Snow struggled to settle on the pavement across the street that would have
been in sun but settled without fuss on the other side that wouldn't
get any sun at all. I was wondering about this at the time and this seems to
explain it.

Even the 1cm covering I had this morning was quickly removed by the sun,
even though there hasn't been that much of it. Somebody else said that
quite a lot on isolation gets through cloud.
Given a max of just 1.9C today that tells you just how powerful the sun is
at this time of year compared to at the solstice.
