    Someone said to me that if it had snowed in the night then it must have been warmer as snow does not fall in deep frost?

    Is that true as I always thought that too?

    Point taken,, just that the old phrase "too cold for snow" keeps coming to mind...

    There are temperatures where it's too cold to snow, because the air can't hold enough moisture for snow to form. However, this only happens at around -40C, so it's unlikely here.

    In Ireland, it's usually the case that it doesn't snow when it's very cold (lower than -4C, say) because it takes clear skies for it to get that cold. Conditions over the last while have been rather different.

    I've seen falling snow in -17C or thereabouts in Finland.

    Thank you; it is a memory from an English childhood and of course these are unusual times indeed.

    It was always that when snow came the temp had risen slightly from deep frost. Here now it snows regardless... But Ireland IS damper anyways.
