A very potent and active weather system will produce a wide range of issues for the Upper Midwest this weekend. With the weather pattern is set up the way it is currently, several waves weather are expected to pass through the region bringing concerns of heavy rainfall and river flash flooding and severe thunderstorms and tornadoes to a wide part of the region, but especially across the state of Iowa. The cause of the active weather is a warm front which has been parked over the region the pass few days and will continue to remain over the area. Warmer temperatures and more humid air will result as the warm front inches farther north into the state of Iowa and Southern Minnesota.
Local overview
The warm front mentioned above will make a slow move northward through our area and then park its self over the area over the period of the next several days. The warm front will force in much warmer more humid air, however significant amounts of moisture will be available which will spark several waves of rain and thunderstorms and this will cause problems for the local area. With the expected system locals can expect concerns of very heavy rain and river flash flooding and several severe thunderstorms risks. Widespread very heavy rain is likely with amounts ranging from 3-5" over the Iowa communities and 1-3" across the Minnesota Communities. Rivers are already very high from the past few weeks rainfall. Flooding concerns are to a very high level for areas and communities along creeks and rivers with the areas of highest concern are along and south of the Iowa border where much of the heavy soaking rains. Also a concern is that conditions are right for several waves of severe thunderstorms with hail and highs winds as well as a tornado threat. People should be aware that there will be several days in a row with these risks. Monday through Friday will carry the risks for severe storms and heavy rain.
