Good morning all! We are tracking a winter storm that will likely wreck part of the midwest and bring rain and snow to our area. Because of this, portions of Southern Indiana are under a Winter Storm Watch tonight and tomorrow morning for the potential for freezing rain. The Indiana counties in our viewing area included in the watch are: Jefferson, Scott, Washington, Orange, Lawrence, Jackson and Jennings. If you are traveling through Indiana tomorrow morning (for instance Interstate 65 past Clark County), you may run into some icy roads.
Below is a look at the chances for ice accumulation of a tenth of an inch, which doesn't sound like much, but can cause a ton of problems for commuters. This shows a 10%-40% chance of 0.10" ice for the counties in Indiana that are listed in the watch. However, parts of Missouri, Illinois, Indiana and Ohio could receive around a quarter of an inch of ice accumulation by Wednesday which would create a major ice storm with power outages, closed interstates, cancelled flights, etc.
Now, as I mentioned, most of this is going to the north of our area. We will have rain today and tomorrow. In fact, we could have thunderstorms and heavy rain tomorrow night. After that, the cold front sweeps through bringing a few light snow showers on Wednesday. Right now it looks to be less than an inch accumulation. The NAM (to the left) shows a light dusting of snow for the area; however, the GFS (not shown) is a little more aggressive with snow totals, but it only shows about two inches or less for the entire area. Both show the lightest accumulation to the south and higher accumulations in Indiana.
