About 2 years ago on a Wednesday evening about 5pm we had a thunder storm
with snow. I had never seen thunder and lightning before with snow in all
my (quite long) life.

This was in North Surrey by the way near Croydon and Sutton.

Does anybody on this friendly group remember it? Is it really that unusual?
What caused it?

I think it was in January 2004, like you it's the first time I saw a
thunderstorm with heavy snow. It's quite unusual in this country,
because you need very cold air undercutting mild air.

Do you know the answers to everything!!
I was in Coulsdon that evening...the traffic came to a standstill and I saw
two motorcyclists come off their bikes in the space of 10 minutes. Had about
4 inches of snow here - the local kids loved it.

28th January 2004, very dramatic just north of the M4 near Heathrow. A
squall line was the cause I seem to recall.

All depends on whereabouts in the country you are, Joe. On coasts
exposed to polar maritime airmasses heavy snow showers accompanied by a
single "flash-bang" are quite common in winter. On the west and north
coasts of Scotland there are more thunderstorm days in winter than in
summer.

Dave Wheeler might have some thoughts on this, being well and truly in
the firing line.

This was my enhanced MODIS image for the day after, showing the extent of
lying snow. It was published soon after in "Weather" IIRC, though I don't
have a copy.

Tell that to my son zapped by a bolt from a snowcloud in West Wales...

Does she mean the "Thundersnow" band that worked it's way down the country?
Came through here like a train.. excellent! Tracked oit on radar and told
partner "In the next few mins there will be a strong wind accompanied by
sudden rain turning immediatly to heavy snow qalong with thunder..." Stood
in the front garden and saw it move up the street...

My forcasting went up in her estimation, never told her i had tracked it for
hours and read descriptions of it's passing on here. ;o)

Wow! I didn't realise I'd witnessed something so unusual last month, when
on 4th March I posted to here about thunder and snow. I feel privileged
now
