Tonight: Mostly cloudy with some spotty light snow late (30% coverage). Low: 31°.
Monday: Scattered snow showers early (60% coverage) then mostly cloudy and chilly. (Some ½"-1" totals possible with 1" on the high side). High: 38°.
Tuesday: Cloudy and cold with scattered snow showers (40% coverage) mainly along the TN/GA border. High: 38°
The cloudy and chilly conditions will linger overnight Sunday, with lows in the upper 20s-lower 30s for most.
A fast moving, weak disturbance will rotate across the region on Monday morning, which will be capable of producing some light snow showers (around 60% coverage).
Snowfall amounts will range from Trace to ½" amounts for most with some ½"-1" totals possible across the plateau into Kentucky. Be advised that there is the possibility for some travel problems, where some of the higher totals are achieved.
From late morning Sunday into the evening Monday, conditions will remain cloudy, dry and chilly, with highs in the mid-upper 30s.
Monday night appears to be dry as well, but as we go through the day Tuesday, another band of snow will be possible across the southern tier of our viewing area. The most likely area will be south of the I-40 corridor towards Chattanooga into northern Georgia.
This band will most likely be small and have a sharp cut-off gradient. Any jog north or south would affect snow totals across the region on Tuesday.
From late Tuesday afternoon into Wednesday, this band of snow looks as though it will push farther north, as an area of low pressure moves northeastward through the Carolinas.
This track and timing is has the lowest confidence at this time, so we will need to see how it develops. That said, if the low follows this path, this would give a greater opportunity for more significant accumulating snow from the I-75 corridor eastward, across our area.
To sum it up, our confidence is high with the early Monday system, medium to high for the Tuesday system and low to medium for the Tuesday night into Wednesday system, because there are several variables that will come into play and are not well defined at this time.
