Warm Winter Ahead for Knoxville: A Pleasant Surprise!
As we gear up for the colder months, people in Knoxville can breathe a sigh of relief. This year, it looks like winter won’t be quite as harsh in East Tennessee. Exciting news for those who dread the frigid temperatures! According to the latest predictions from the National Oceanic and Atmospheric Administration, winter this year may bring milder weather in December, January, and February.
What’s Causing the Warm-Up?
You might be wondering, “What’s making the winter warmer this time around?” The likely culprit is a weather phenomenon known as La Niña. We’ve got about a 74% chance of seeing these conditions take over, with a 40% chance that it will be a moderate event. So, what exactly does this mean? La Niña entails the periodic cooling of ocean surface temperatures in the central and eastern equatorial Pacific Ocean.
During La Niña, the trade winds become stronger, pushing warm water towards Asia. This shift in warm water has a knock-on effect, pushing the jet stream northward. In simpler terms, this results in warmer and drier conditions for us in the southern states, while the Pacific Northwest experiences cold and wet conditions.
Knoxville’s Winter Temperatures
Now, it’s normal for Knoxville to experience temperatures hovering in the 30’s and 40’s during the winter months. These “normal” temperatures aren’t just pulled from thin air; they’re based off a 30-year average from 1991 to 2020.
Just recently, the Great Smoky Mountains showed us how unpredictable nature can be, with an early dusting of snow falling on October 15. The LeConte Lodge, nestled near the peak of Mount LeConte, reported receiving approximately 4 inches of snow. It seems that even though the rest of the area might enjoy mild conditions, the mountains are already getting into the winter spirit!
How Does La Niña Compare to El Niño?
If you’re familiar with the weather terms, you’ve probably heard of El Niño. This phenomenon is like La Niña’s opposite twin. Where La Niña brings colder ocean temperatures, El Niño means warmer waters shifting towards the U.S. East Coast. El Niño generally leads to a drier and warmer northern U.S. and Canada while giving the Southeast more precipitation.
What to Expect This Winter
With the predictions lining up like they are, the Old Farmer’s Almanac is also jumping on the bandwagon, forecasting a “wet but mild winter” for Tennessee, aside from our snowy friends in the Great Smoky Mountains.
Carol Connare, the editor-in-chief of the Almanac, has pointed out that “this winter, temperatures will be up and snowfall down throughout most of the United States.” So, for those who enjoy a cozy winter without the extreme chill, there’s good news on the horizon.
Mark Your Calendars!
For those keeping track, meteorologically speaking, winter officially begins on December 1. However, many still celebrate the season’s true arrival on the winter solstice, which falls this year on Saturday, December 21, marking the longest night of the year.
As we prepare for the upcoming winter months, it seems Knoxville residents can expect a more pleasant winter season, without the biting cold that can often accompany it. So grab your hot cocoa, bundle up in your favorite blankets, and enjoy a mild winter!
