The science of winter precipitation
When precipitation is all rain or all snow, the atmosphere is either greater or less than 32°. If you add a wintry mix – freezing rain or sleet – then you have to assess the temperature at different levels of the atmosphere. Check out the image below, which shows the layers of warm (> 32°) and cool air (< 32°) that help determine the type of precipitation that reaches the ground.

Our focus is not on snow as there will be layers of warm air melting the snow. What we will be focusing on is rain, then temperatures just below freezing and transition to freezing rain and sleet. Fine-tuning of this part of the forecast will only happen as we get closer to the forecast period. One thing is certain: Freezing rain and sleet are both ice, and this accumulation can create travel hazards and power outages.
