The greatest concern for the strongest storms will come down the Mississippi River from north to south out of Iowa late Friday evening. The counties inside the black outline are the ones the local NWS office is responsible for issuing warnings for. The warmer the colors get on the chart, means the greater the level of concern/risk.
