I saw your explanation and moved it to Discussion comments below. To answer your question - No. That small bit of rain won't melt so much snow. 3mm is only about 1/80 of 25cm. It would take a lot more rain and very warm temperatures to melt that snow in one day. Then your area would likely have flooding.
Yes, because water is warmer than the snow.
Acid Rain. WHAT NAO?!
It does tend to, because it's made of snow and rain. Rain is warmer than snow and so will melt it - unless the temperature at ground level is sufficiently cold for the rain to freeze when it comes into contact with the snow already on the ground.

This will depend on how cold it is, but on average 10 inches of snow = 1 inch of rain, so 0.15 inches of rain = 1.5 inches of snow. It could be less than in inch of wet snow, or more than 2 inches of powder, however.
The world DOES receive more rain than snow.
Snow is frozen rain, which means the colder it is, the more likely it is to snow! This is why rain melts snow, as it is warmer. Snow is just rain, but a bit colder, so it's frozen. If it's very cold, below 0 degrees Celsius, and it doesn't rain but the clouds go dark, it is more likely to snow heavily and thickly, than to rain.Hope that helped you!
No, a desert generally receives very little precipitation (less than 10 inches annually), and even less snow.
About an hour. But if you start off with a gallon of snow, you'll have much less than a gallon of water when it all melts.
Rain falls much faster than snow. Snow has much more air resistance than raindrops.
rain is more common than rain
Yes, the Painted Desert, which is part of the Colorado Plateau Desert, does get some rain and snow but less than 10 inches (250 mm) of total precipitation per year.
