Snow Falling at 43°! What's Up?

The key to this is that ice can only form where the temperature is below freezing.
In case you are wondering the wind chill cannot make water freeze if the temperature is above freezing. Wind chill only tells you how fast something will lose heat and cool to air temperature.

The snow flakes formed high in the atmosphere with sub-freezing temperatures.  The freezing level this afternoon was at most only 2500' up. So if a flake could stay frozen as fell to the ground you saw snow. Most of the flakes melted to rain drops.
