The Top photo is the GFS. The lower photo is the ETA using a modified method of snow accumulation. Both have shifted slightly Southeast. The gradient is still extremely tight and have from Louisville northward anywhere from 6-12 inches of snow. It is a very slight shift…only about 30 miles or so but as previously mentioned, a little wiggle like this makes all the difference. What is clear is that someone in the viewing area will get a snootful of snow. Others will get a fair amount, lets say 1-3 inches. If you click on the images, you should get an idea of how tight the gradient is. Two things to remember: One is that these are just what some machine thinks and its possible the wiggle may be farther north; the other is that if you like snow, it’s a good sign that both models are pretty similar. However, when delving into some of the numerical data, some suggest all snow while others suggest a fair amount of sleet which would cut down on snow totals.
Get your work done today and expect a wintry situation, especially late Friday through Saturday. The event will probably not wind down until late Saturday. Saturday can be expected for most areas to be all snow. The event will start early Friday with many areas getting a cold rain before it turns over to sleet and snow. The northern part of the viewing area should expect all snow. It’s not out of the question that some areas in the Southern Indiana may get more than a foot. This may be fun.
