Expect some cold temperatures in the area. Expect some cold temperatures in the area.

Saturday night: Clouds slowly increase across the region. Low: 30°.

Sunday: Mostly cloudy, breezy and mild with a slight chance of a late day shower (30% coverage). High: 52°

Sunday night: Rain likely (100% coverage) that quickly changes to snow as Arctic air arrives. Temperatures falling through the 20s.

Monday: Very cold with light snow/flurries lingering. Temperatures continue to fall through the teens.

Clouds will slowly return overnight Saturday into Sunday from south to north, which will keep temperatures in the upper 20s-lower 30s. The increasing southerly wind on Sunday will help to warm temperatures into the upper 40s-lower 50s before the big shot of Arctic air arrives Sunday night into Monday.

It appears the system will move across the plateau Sunday night between 6-8pm central time, starting as rain before quickly changing over to snow as the cold air rushes in.

The rain-to-snow will move into the valley between 8pm-10pm and into the mountains shortly after that. This timing is based on the current information we have, so please keep checking in for any changes in potential arrival times.

The system is expected to move though quickly, which should help to limit excessive snow totals, but it appears as though this system could produce more snow than the one that came through Thursday night.

The bigger impact of this front will be the brutally cold temperatures that it will bring. Temperatures will fall from midnight Sunday, with highs in the mid 20s down through the teens during the day Monday and bottom out in the low single digits to near 0° by Tuesday morning.

These temperatures will most likely set record lows for many locations, as Knoxville's record for January 7th is 6° set in 1970.

This cold snap will could keep temperatures below the freezing mark for 60+ hours before we finally see a thaw after the middle of next week.
