If you look at the first chart you can see that at lower temperature the maximum amount of humidity the air can hold go down. At around 0 Fahrenheit or -18 Celcius the air need to be close to the point of humidity saturation for snow to fall, which doesn’t always happen. If you drop your temperature below that, it become harder and harder to meet the condition for snow to fall. The air simply can’t hold enough humidity for snow to form.
