Large patches of disorganized rain showers are moving eastward this afternoon across the Midwest. While this precipitation is mostly light rain, it is a nuisance. There does appear to be a bowing feature in southern Illinois which is likely producing heavier showers and thunderstorms, so be careful if you are around that area.
As of right now, temperatures compared to normal are in quite a hole, especially in the NW Illinois region back through South Wisconsin, Iowa, the south half of Minnesota and East Nebraska. That is the top left graph. The top right graph is current temperatures as of right now. The bottom two images show stations with temperatures in the coolest 10% vs. the 1981-2010 average (bottom right image), whereas the bottom left image shows stations in the warmest 10% vs. the 1981-2010 averages.
