However, this relates to the air at higher altitudes and it quite possible that a layer of cold air is at ground level, forcing warm moist air up, causing it to condense and then freeze into snow which then falls through the cold air layer.

Weather's a complex thing, for sure! As rekstout says, it all depends on topography, temperature bands and weather fronts (I'm just back from Austria where the temperature at ground level was -10C and it actually was snowing!).
If you have a look at www.snow-forecast.com, you will see that the biggest dumps of snow occur when ground temperatures rise significantly - that is why we tend to get snow for only 1-2 days at a time (we need a cold snap then a warm front - this is why a White Xmas is so rare!).
......and Antarctica is actually classed as a desert region in many places - the snow just blows around, and doesn't often fall!

When there is an anti-cyclone in a certain area this produces no clouds, which in turn produces lower temperatures than if there were clouds. Obviously you need clouds to produce snow, so if there were no clouds in the area leading to lower temps then that is, possibly, where the saying comes from. If you get my drift. Boom boom
