410 AM CDT Wed Mar 13 2019 …River flooding and Significant Ponding Water Likely This Week Due to Snowmelt and Expected Rainfall… .The combination of warmer temperatures and forecast total rainfall amounts of one to near two inches is going to lead to a rapid snow melt across much of central Iowa. Significant ponding of water in low lying, poor drainage is likely, potentially impacting roads and travel. Periods of rainfall are likely today into Thursday, with the highest totals occurring today into this evening. The runoff from the snowmelt and rain will lead to significant rises on area streams. Ice jam flooding may occur, creating rapid rises upstream of the jams. Minor to moderate river flooding is possible by Thursday and into the weekend.
