Atmospheric Layers

This is a list of the atmospheric layers. At each of these layers, there is some form of wind speed, wind direction, humidity level, or temperature that plays a roll in what the weather will do. These layers are always seen in soundings, and you can refer to this page to describe what each layer's roll is.

The 850mb level sits at around 4781ft above sea level, and is the first barrier to snowfall occurring. This layer, if warm, will melt all small frozen precipitation, if above freezing. If it continues to warm up all the way to the surface, the precipitation will most definitely be rain. If it is below freezing at the next layer, 925mb, it will be sleet at the surface, unless your elevation is higher than 925mb, then it will be rain. If it is below freezing at the surface only though, the precipitation will be freezing rain.
