Ground Temperature for Snow to 'Stick'
Date: Spring 2012
How long does the ground need to be cold before snow will 'stick' [as in more temperate/hot climates]?
The temperature of the ground or vegetation at the surface is
more important than the length of time that the ground is cold.
If the temperature of the ground or vegetation is near
or below freezing, the snow will stay and not melt, assuming that
the air temperature is near or below freezing.
