The perfect conditions for snow are . . . Christmas!
bellow freezing i would have thought. well bellow freezing up at cloud level.
cold north winds combined with snow clouds
To snow it is necessary a high concetration of water vapour in the atmosphera, the temperature less than 0ºC (32ºF) and the isobaric pressure is less than 1000 mb (between 500 and 1000 mb)
3°C and below for snow all though it needs to be below 1°C for a guarantee of no rain. Usually small individual dark Purple clouds and/or yellow clouds/sky is an indication of a heavy snow front though this could mean snow ~100-150 sq miles from your position. Hope this helps and hope it snows!
if the air temperature is so cold that the water droplets freeze, tiny ice crystals form in the clouds. These ice crystals collide with each other in the clouds or grow delicate shapes. The ice crystals combine to form snowflakes. There may be hundreds of tiny ice crystals in a single snow flake. These snow flakes fall from the clouds to form snow on the ground.
If the air temperature is not too cold and the air is very moist, the snow flakes may grow into very large flake up to 1 or 2 centimetres across.
cold dry air,you can kind of feel it,theres a funny smell too…..I can always tell when its going to snow
well you heard of the phrase to cold to snow hay sweetheart well this is true in a way 2 c or less is ideal for snow warmer than that it will be sleet or rain it generally gets colder after the snow has fallen darling. xx
