This weekend is shaping up to be a messy one. The first half of Saturday will be fine, but then things go downhill rapidly in the afternoon and evening with snow heavy at times. The storm will have a long duration as well, and precipitation will continue to fall on Sunday. What is unclear is the form of the precip on Sunday.
There are two parts to the storm. A big low pressure system will move in from the Ohio valley and bring us our first shot of snow. It will come down heavy at times Saturday evening. But this storm's center is going to track to our west, which means warm air from the south is going push into our area. The warm air will lead to sleet and freezing rain and then eventually rain.

As the warm-up is happening, a secondary low pressure system is going to form on the coast to our south. This system could counteract the warm up and bring cooler air back into play, which would change liquid precipitation back to frozen precipitation. The models are not in agreement about this secondary low.
So, the total inches of snow with this storm are going to be hard to predict. We should be around the 6" mark, but who knows what the sleet and rain will do to compress the snow. And then if we get more snow from the secondary low, then that will re-raise our totals on Sunday.
Were this storm to have arrived on a school day, snow days would have definitely been in order for all students.
Right now we expect snow to start around 2:00 PM on Saturday, and precipitation in some form will continue through Sunday afternoon.
