How to predict inches of snowfall


Here's an example for Saturday's precip of .957 which tells us little about how much snow that could be.

Roughly, 1 inch of rain equals 10 inches of snow. There is a lot of variability in the density of snow so this estimate is not always accurate, but it is usually pretty close.

So, when you see a precipitation forecast of .5 inches, this could mean 5 inches of snow.

So, just move the decimal one position to the right and that's the snowfall. Easy enough!

.25 precipitation = 2.5 inches of snow

.05 precipitation = .5 inch of snow

My sister's right, just move the decimal once to the right. We get cold and avoid snow at all costs!

Of course the wetness of snow can affect the depth, but this works well enough for my needs.

Quiz: 1.25 inches precipitation = how much?

12.5 inches of snow! You got it! So, remember that example of .957? That could mean 9.5 inches of snow. Could be a lot of snow for me if it's dry and fluffy! But, doubtful because of the rain.

If you forget which way to move the decimal, just remember the number must get bigger because snow is much taller than rain.

No matter how much snow we get, I'll be staying warm!
