Will Snow Accumulate If The Surface Temperature Is Above Freezing?
Every year, when there is a chance of snow following a period of warm temperatures, there are a handful of people who are quick to criticize that “it isn’t going to accumulate, it’s been too warm.” While this may seem like the most logical answer, there is on major factor to take into consideration.
Will snow stick if its above freezing?
The greatest factor to snow accumulating when the surface temperature is above freezing, is the rate at which the snow falls. If the snow is a gentle snow globe type of snow, then yes, the snow will melt on contact. BUT, if the snow is falling at a rate where it is reducing the visibility, then the snow will likely not melt quickly enough and will begin to accumulate.
This is because the rate at which the snow falls onto those surfaces exceeds the rate at which the snow can melt. An example of this is a clogged storm drain. If the rain stops, the water will eventually drain into the sewer. But if there is heavy rain, the water will back up and will flood the roadway. For the current surface temperatures, visit here.
