KNOXVILLE (WATE) - It is hard to believe that we saw some areas hit 60 degrees today and some will see snow tomorrow! It will remain clear and mild early tonight, but clouds and colder air will start to funnel in overnight into early Tuesday as yet another "clipper" system arrives.
There will be some light snow, possibly mixed with rain, for some areas towards daybreak, but temperatures will be right at or still above the freezing mark. The better opportunity for snow comes from mid-morning across the Plateau and Valley to late morning across the Mountains.
But just as quickly as it arrives in the Valley, it will taper off leaving little, if any in the way of accumulations. The light snow will continue across the plateau until early afternoon, but will last through Tuesday night for the Smokies.
This is why the highest totals will be found for areas above 2,500 ft or so. As of now, it looks like the plateau and portions of S.E. Kentucky and N.E. Tennessee will see snow totals up to 1 inch, but most will see less than that. The Mountains could pick up two to four inches or more for higher peaks, while along foothills and most valley locations will see trace amounts to none.
The bigger story will be the temperatures, because they will tumble through the day and end up in the teens for many on the plateau, in S.E. Kentucky and in the Smokies and 20s across much of the Valley by sunset. This cold pattern will stick around the rest of the week as well.
Tonight: Clouds and cold air roll in late with a light rain/snow mix towards daybreak (30% coverage). Low: 36°.
Tuesday: Windy and colder with scattered light snow showers or flurries (little, if any accumulations for most of the Valley). Temperatures fall from the mid 30s in the morning into the 20s by evening.
