Watches and warnings for our area Watches and warnings for our area

Tonight: Rain likely (100% coverage) tonight,  changing over to snow around midnight in the valley. Some near 1" totals will be possible for valley and plateau locations. Higher totals for the Mountains (especially above 3,500ft).

Temperatures will be near freezing around midnight and fall into the teens by daybreak.

Monday: Windy and very cold with a few flurries possible. Temperatures will slowly drop through the teens during the day.

Monday Night: Windy and bitterly cold. Low: 2° (Wind Chill Values between -5° and -20°).

Tuesday: Partly cloudy and frigid. High: 17°

Highs actually made it up into the mid-upper 50s for portions of East Tennessee on Sunday, but don't get used to it. The Arctic air is still set to roll across the region overnight and stick around until Wednesday.

Rain will spread across the Plateau/S.E. Kentucky this evening and into the Valley early tonight before temperatures drop off below freezing during the overnight hours. This could be problematic, because where there is standing water, because we could see some black ice before the chance for light snow arrives.

There still looks to be a narrow opportunity for some accumulating snows behind the rain as the Arctic air moves in and before the moisture tapers off and shifts to our East across the Mountains. This could produce some near 1" amounts for many areas across the Plateau down into the Valley with much higher totals expected above 3,500 ft. in the Mountains.

The main focus continues to be the frigid air that will cause temperatures to tumble area-wide overnight through the day Monday and bottom out in single digits or even some below zero reading by Tuesday morning. Wind Chill Values will be potentially dangerous as well, especially from Monday P.M. into Tuesday morning as readings could fall to between -5° to -20° in many locations. There will be a slow thaw for the second half of the week and some above-average readings possible by next weekend.
