A weather estimate for rain can quickly switch to one calling for eye if a suddenly temperature fall occurs. Even a little amount of rain deserve to turn into a severe snowstorm the accumulates numerous inches of eye on the ground and makes getting roughly difficult. Fortunately, it"s basic to convert inches the rainfall come inches that snowfall to get a feeling for what come expect and to have the ability to modify her plans accordingly.

Perform the baseline rain-to-snow conversion. The baseline ratio of rain to eye is 1 customs of rain equates to 10 customs of snow. Because that example, to calculate the snowfall equivalent of 3 inches of rain, multiply 3 by 10 to acquire 30 inches of snow as the baseline conversion. This conversion applies for snow falling at temperatures near freezing, in between 28 and 34 levels Fahrenheit.


Find the temperature in the location for i beg your pardon you"d choose to carry out the conversion. You can track under this details via the nationwide Weather Service, for example, or any number of other meteorological sources, such together the Weather Channel. In general, chillier temperatures make snow autumn less densely and lower the rain-to-snow ratio, result in an ext inches of eye per inch of rain.


Adjust your conversion to account for temperature if the external temperature is less than or equal to 27 levels Fahrenheit. To calculation rain to snow for temperatures between 20 and also 27 levels Fahrenheit, main point rainfall by 15 rather of 10. For temperatures between 15 and also 19 degrees Fahrenheit, main point rainfall through 20. Between 10 and also 14, multiply by 30; in between 0 and 9, multiply by 40; between -20 and also -1, multiply by 50, and between -40 and also -21, main point by 100. For example, to calculate the snowfall equivalent of 3 inch of rain in ~ 5 levels Fahrenheit, main point 3 through 40 to attain 120 inches of snow. Therefore, if 3 inches of rain are expected yet the temperature drops suddenly to 5 levels Fahrenheit, 120 customs of snow will fall.


Perform the calculations in turning back to calculate snow to rain. For example, for 8 inch of eye falling in ~ a temperature of 20 degrees Fahrenheit, divide 8 by 15, because the conversion factor for 20 levels is 15. The result is approximately 0.53 customs of rain. Therefore, 8 inch of snow that dropped at 20 levels Fahrenheit will melt down to about 0.53 inch of rain.


plenty of factors influence snow density apart indigenous ambient temperature. Wind, for example, can compact snow and cause it to fall more densely, lowering the rain-to-snow ratio.
