 How much additional rain is coming? Well, before the end of the month, in many areas, we'll get about a half an inch or less. That's what these blue and green shades are. In northern Minnesota and across parts of Wisconsin, though, there will be some communities that get a little more than that. Most of this will come on Friday. And if you're wondering, is this a lot of rain? Is this a lot of flooding in general? Yes.
