The latest radar picture this afternoon continues to show the weather system affecting our area today pushing off to the east and northeast. Low pressure looks to be centered near Decatur, Illinois with a warm front branching off to the east and a cold front to the southwest. The bulk of the moderate-to-heavy snow is over much of Minnesota and Wisconsin this afternoon, with Iowa only seeing the affects of three main bands: one extending from the bulk of the snow in Minneapolis towards Denison (which appears to the heaviest at this time), another from Rochester towards Knoxville, and another from La Crosse to Manchester. Most of the precipitation south of Highway 20 is in the form of rain or freezing drizzle, whereas to the north we’re seeing mainly snow.
Road conditions are not too terrible across the north this afternoon. Most roads are partially covered with sections south of Highway 20 in the clear aside from some wet pavement. In any regard, make sure to continue to take it slow on the roads, especially with the potential for slick roads in central Iowa during the afternoon commute and continued partially covered roads in northwest and north central Iowa.
Winter storm warnings remain in effect for 13 counties in northern Iowa with Winter Weather Advisories extending down towards Interstate 80. These remain in effect until early Wednesday morning. While snow will begin to lighten across many locations, we should see another wave of upper level energy which will continue the snow through this evening. In addition, winds will begin to pick up on the back side of the system leading to blowing snow and hazardous travel.
