Hi there, long-time lurker, but have been following this newsgroup closely
over the past couple of weeks watching Will's very early snow prediction
coming to pass - very exciting to follow! What was the phrase that hooked
me in? "Significant snow event"?

Anyway, I'm modelling a wintry scene in 3D on the computer for an
animation, and would like to know if it's possible to have a snow shower
whilst there's heavy fog?

Hi Nick

I was in Castleton in the Peaks today and over Mam tor that was the
what we got. After earlier showers the cloud base dropped before
another shower came over.

Thanks.

Thanks Simon - I'll get modelling Not sure if my computer is up to
modelling a million or so snowflakes quick enough, but I'll have a go!

It would have to be one that has been advected from elsewhere. I can't
recall seeing this happen for myself but I do remember forecasting one for
Wattisham about 35 years ago. I'd been tracking it northwards(!) across
Essex where it had been giving heavy snow. I'd had reports that the snow had
reached the edge of the airfield so I went into Met Briefing at 0830 - when
we still had dense fog and sky obscured - and confidently forecast snow
would occur very shortly. As I left the control tower at 0845 to head home,
the fog suddenly cleared to show a clear blue sky.

If the shower had made it to the airfield before dissolving, I'm not sure
what the effect would have been on the fog. The snow might have triggered a
glaciation of the fog to turn it to ice fog, which often leads to a thinning
of the fog. I've seen this happen when a slight breeze shakes hoarfrost from
the trees and a water fog has suddenly changed to an ice fog.

Don't forget that if the snow is heavy enough the effect on visibility
will be much the same as fog.

Graham, I reckon snow showers on low ground disperses fog, as does
rain Was at Binbrook in 1965 and we were in fog only just below 0C,
the whole lot fell out in a myriad of crystals,plates and needles at
0200. Over a snow cover, and left a starlit night - never forget it a
wonderful sight.

True enough on low ground inland, but, rain doesn't disperse fog here!
Our thickest fogs come with driving drizzle and a strong to gale SW!
(I'm talking 50-100mm visibility at beach, not cliff top level) Hard
to tell where the sea ends and the sky begins.

In contrast, this sort of fog is rather nice http://www.easterling.freeserve.co.uk/wpage6.html
(4th, 5th & 6th photos down) It's great having a swim around, with
only the swell telling you which direction the beach is in. Can be
quite spooky in a small boat.

50-100 metres visibilty that should be - before anyone tells me!

Snow showers in hill fog are commonplace. Anywhere in this country above 300m
and sometimes lower than that will experience snow showers in fog quite often.

Hi Nick

another shower came over.
Simon. I used to go up Back tor years ago. A good mountain with a
track up from Strines Inn. Had Wallabies in those days, turned loose
by Glossop zoo in the War; been told they have died out now - sad.
Anyway I often went on my own and got caught out around Jan 1973 in
snow and fog, just came down and 200M in snow and fog is not nice
needed compass to get back, frightening. On low groung though
visibility in fog tends to improve in rain or rain showers, seems a
straightforward case of coalescence.
Cheers
Paul.
