Hi everyone,

I've got a question about snow which i'm hoping you guys can answer for me.

Why is it that if its 2C in october or november if will quite often rain
instead of snow and yet come April it can be 7 or 8C and snow quite
readily. I'm guessing it has to do with the temperature of the surrounding
seas but i may be wrong.

If the wind is blowing fast enough high enough it would climb even
higher over warm air already here wouldn't it?

Then as the wind blows the base cover away we get some nice wet snow.

Just a guess.

Firstly I think it is to do with the thickness of the troposphere. See
http://homepage.ntlworld.com/booty.weather/metindex.htm for explanation
of thickness.

Secondly, it is to do with dryness of the air, if the air is dry enough,
any snow falling will not melt into rain.

The sun is stronger in April than in October or November, so the ground
- and from there the lowest part of the atmosphere - is quickly warmed
up. So though the temperature at the surface is 7 or 8C, the freezing
level (or more correctly the melting level) may be not very high up (and
will descend further in a heavy shower), so the snow doesn't have time
to melt before reaching the ground.
