Completely off-topic help needed :)

Another vote for that - I'd also like to know whether
the substance just now coming is water or snow (and
it's perfectly normal at this time of the year here
in the far North, Helsinki, Finland, 60 deg N).

One of my 8 year old son's class assignment questions reads, "How can
you look at the clouds and know if it is about to snow?". Never having
seen snow, I hadn't the foggiest idea. Asked a few friends and none
knows either! A quick search on the internet but came up blank,
probably because I haven't given the keywords that might elicit the
correct answer. Wonder who here (Dubai, UAE) came up with such an
irrelevant question!

Any Canadians here who can help? Or anyone near Chicago (snows there,
right?)?

Thanks much in advance and apologies to the rest,

Think I'll give him Neil's answer because it looks nice and logical
too. I remember similar Qs at school regarding impending heavy rainfall
and answering, "Dark, low clouds". I wondered if snow meant clouds
being pure white, which apparently is not!

And what do u mean you can't tell whether what's falling is rain or
snow?

When the temperature is at zero C, there is a snowfall
with the snow crystals wet with water, so the material
coming nearly horizontally and chilling your face is
both snow and rain (slush?). Of course, there is an own
word in the local language for it, though we do not have
as many different words for different kinds of snow as
in the Eskimo languages.

Could the question contain the idea that the rain falling
is only cold enough when it is coming from a CB or TCU?

Wonder if it's sleet you're talking of? I haven't seen that either

Right, that's the word.

Welcome to have a look at it!

It's a real salesman who can sell tourist trips to
the gloom & sleet we have now.

It's a different thing in the summer - it does not
get dark at all (even in the middle of night). The
local authorities do not accept a night flight as
night time for the time between first of May and
last of August.

Wow... I had never thought of that before - an entire country of pilots
who are not night current as of July 31 every year. (at least by
the FAA rules)

Obviously, there are pilots in the authorities, as well.
It's not so difficult - you do not need the currency. Maybe
we had something to explain to the FAA if they were here.

The same phenomenon applies to all the Nordic countries
(or at least Iceland, Norway and Sweden).

There is the balance, of course. In the far North of the
country, the Sun stays below the horizon for months in
the middle of the winter.

For reference, currently we have daylight roughly from 8 am
till 4 pm.

You must get a lot of Stop & Go's on the first week of September!

Right. It's particularly fascinating with a Turbo Arrow
in the middle of Cessna 150's.

Most rain begins as frozen water, at high altitudes. Then
the snow or sleet melts on the way down into warmer air. In
your dry desert air, you get virga, which is falling water
evaporating in the lower, dry air.

The amount of water available for precipitation can be
judged by the density [darkness] of the cloud. But it can
snow from clear air, as water vapor sublimates directly to
crystal form.

This link is to AC 00-6, in several PDF files, it has many
answers.
