For our viewing area here in northwest AL, southern middle TN, and northeast MS, I'm getting increasingly concerned that instead of a "clean" ice storm... a large part of our area may see a situation where we lay down widespread upper-end advisory to low-end warning criteria ice Sunday evening into predawn Monday... and then a large part of the Monday "main" event ends up as a little more freezing rain, a bit of sleet, and then several inches of snow. Temperatures will likely never get out of the 20s for the heart of my viewing area (Shoals metro up to Lawrenceburg), and with an average 0.75-0.9"+ QPF forecasted... with every single bit of that being some form of wintry weather. Temperatures will support snow ratios of 12:1 to 16:1 or even higher once it switches to snow, even as far southeast as the Shoals and southern middle Tennessee. If this doesn't stay a "clean" ice storm, I think many people may be surprised by the snow amounts they may see sitting on top of the ice. If it stays a "clean" ice storm, I wouldn't be shocked at some 1" ice accretions near the U.S. 43 corridor of northwest AL and southern middle TN.
For this portion of the Tennessee Valley, this will be the most impactful winter storm since at least January 2011, if not way before. This makes me think of the big winter storms of the 60s, 70s, and 80s.
