I don’t very often write super serious blogs, but this one may be the exception. Really the only exception is when we’re talking serious weather in the Tennessee Valley. At that point I think it is very important to take a step back and stick strictly to being informational as opposed to sarcastic like you’ll often find in these blogs.
Let’s start with the most basic and then we’ll get more detailed from there. It is going to snow Tuesday morning. This round of snow will move west to east starting before the morning commute and exiting the area around the lunch hour.
This round of winter weather is thanks to a strong Arctic cold front attached to an area of low pressure sitting well to our north in Canada. Through the course of the day Monday that area of low pressure will continue to strengthen and develop. Here in the Tennessee Valley the only impact on Monday will be some very warm temperatures with highs in the upper 50s. That is a nice change from the air we’ve been dealing with.
That cold front will push through Monday night and very early Tuesday morning. We’ll begin with a little rain across the area, but as the cold air settles in behind the front the rain will quickly transition to snow. Again, the timing of the snow will be essentially the entire morning Tuesday. This means one of the biggest impacts will very likely be the morning commute Tuesday.
Accumulation remains to be the trickiest part about the forecast though confidence is growing. As it stands right now I am confident that the entire Tennessee Valley will see at least one inch of snow. From there I do think we could see some locally higher amounts especially along the I-65 corridor. It is there where 2-2.5 inches is very possible. On the extreme end we would be looking at 3 inches of snow before this event is all said and done.
To close there a few certain things: 1. It will snow Tuesday morning. 2. It will be very cold Tuesday through the rest of the week. 3. This is primarily a morning event that will affect the morning commute.
The one thing that is not set in stone are the snow totals. I expect those to change and this blog will be updated accordingly.
