An East Tennessee White Christmas in 2020 would really beat the odds!

On average, the chances for a White Christmas in Knoxville are three to four percent. But it could happen in 2020.

KNOXVILLE, Tenn — If East Tennessee sees a White Christmas in 2020, and the possibility is looking pretty good, we will definitely be beating the odds.

And in a year where so much has been awful,  it seems like we've earned a little joy.

While the forecast could still change, at this point it looks like we could have rain changing to snow on Christmas Eve across East Tennessee. The chances are greater for accumulation in the higher elevations, but even Knoxville could see some snow on the ground.

It will be very cold, so chances are any snow that covers the ground would still be around on Christmas Day, with even a few lingering flurries in some areas.

History tells us this would be a pretty rare event. The National Weather Service (NWS) defines a White Christmas as an inch or more of snowfall.

The last time the Knoxville area saw a White Christmas was in 2010, according to the NWS in Morristown. That Christmas Day, NWS recorded 2.5 inches of snowfall in the city.

So it doesn't happen often. Records show just five White Christmases in over 121 years of records.

The most snowfall on Christmas Day in the Knoxville area came in 1969 with seven inches. Other White Christmases include 1887, 1915, 1976 and 2010.

On average, the chances for a White Christmas in Knoxville are three to four percent. It's a little higher on the Cumberland Plateau and in the mountains, about 10 percent, and those areas may have seen snow on Christmas more recently than Knoxville.
