The featured map is forecast probabilities of at least four inches of snow falling over the next 72 hours from the Weather Prediction Center (a part of NWS/NOAA). This will be from a big storm system arriving on Friday and set to bring a lot of moisture into the state. The question remains as to where the rain to snow transition will be and the featured map depicts a forecast location of north and northeastern Iowa. Other parts of the state are expected to receive significant amounts of rain.
