what is the formula for switching rain to snow in inches?

The general formula is as follows.

About 1 inch of rain = 10 inches of snow.

However, there are various forms of snow. Some is low density while other snow is high density. This will help you in general.

If it is a dry, cold snow and the temperature is BELOW 12ºF than the snow is most likely LOW DENSITY and with the following formula.

12 inches of snow = 1 inch of liquid rain.

If the snow falls when the temperature is between 12ºF and 24ºF then the average of 10 to 1 - 10 incoes = 1 inch of rain - can be followed in general.

If snow is falling and the temperature is between 24ºF and 28ºF the snow is more dense usually and the following forumla is used in general. 7 inches of snow = 1 inch of rain.

If the temperature is above 28ºF and lower than 31ºF than it is usually a heavy - wet and dense snowfall with some melting taking place especially in heavy snows. Then the formula wildely varies but usually 5 inches to 1 inch - 5 inches of snow = 1 inch of rainfall - is used.

RE:

The general equivalent is 1 inch of rain to 10 inches of snow.

However, there is much variability. Very dry snow can be 20 inches to 1 inch of rain. Very wet snow can be 4 inches for 1 inh of rain.It depends on the temperature.

1 inch is 12 of snow.

1" of rain = 10" of snow

any snow is too much
