The forecast models are still grabbing hold of various notions of rainfall coverage and totals through this weekend. To my eye, the European model seems to have a good handle on the possible distribution and amount of rainfall. It suggests widespread half to 1 inch totals across most of Minnesota, with local totals to 2 inches.
