Winter has taken a break, but it will be back shortly. As temperatures rise into the 70s around Knoxville and Chattanooga, it feels much more like March than January. Rain is moving in with several inches expected across the region.
However, the rain and warm weather will likely be replaced with some of the coldest weather of the season by the later part of the month. Weather models are notoriously known for being unreliable weeks out, but they can often pick up on emerging and changing large-scale trends. Moreover, there has been a stratospheric warming event ongoing over Asia for the past several weeks which usually indicates a cold air invasion into parts of the globe between North America and Europe.
Model trends do show much colder air coming into the Eastern United States around late January, but exactly how much and how long it sticks around is the question. If the cold air can remain in place for a period of time, Knoxville could finally see some snow, but it is much too far out to predict individual systems. We will have to continue monitoring the situation and be watching for any potential winter storms. The fact is that the 70 degree temperatures do not look like they will last much longer.
