Episode Narrative The seasons first strong push of warm air moved into Iowa during the overnight hours of the 1st into the 2nd. Temperatures rose through the night with readings soaring into the 60s to around 70 by the afternoon of the 2nd. At the same time, dew point temperatures rose into the mid 50s across southern Iowa. Considerable snow remained on the ground before the warming took place. In addition, rivers were completely covered with ice from the cold temperatures of the preceding month. Rapid melt caused flooding over parts of central and southern Iowa as snow melt water flowed into the rivers rapidly. In addition, the rapid rise in water broke some of the ice free in the rivers and resulted in some ice jam flooding as well. Several highways were reported as having water flowing over them. Flash flooding occurred in Wapello and Marshall Counties due to ice action. There were several reports of washouts on gravel roads as soft soils were eroded by the flood waters. Considerable flooding took place in the Marion County area. Once the flooding occurred, cold temperatures and ice action caused water levels to remain high into the day on the 4th.
Event Narrative Water blocked at a culvert forced water onto Highway 14. Highway 175 also had water backed onto the road surface. Traffic was allowed to pass.
