Right click the link to the sample below, choose "Save target as ..." and save it with your other sounds.
More weather sounds for you. Tricky to find one that conveys the idea of sleet or snow without getting annoying when you hear it every time you take a step outside. This one is fine by me. If you find it too repetitive then either don't use it, find another sound or start doing stuff outside rather than just walking about.
