The northern Indiana office of the National Weather Service (NWS) published the above inforgraphic this afternoon to communicate meteorologists’ latest thoughts on the magnitude of the incoming winter storm. As you can see, they’ve revised the snowfall forecast to four to seven inches for much of the forecast area and seven to 10 inches for the remainder of the area. The dividing line appears to go from southwest to northeast right through the center of Allen County. The NWS tweeted that forecasters will be looking at latest computer model runs this evening and tonight and might thereafter issue additional updates to the winter storm watch. The latest version of the watch appears below.
