Any flood will depend on how fast it gets warm, how warm it actually gets, how long it is sustained, and if we get measurable precipitation in conjunction with the melting.
According to NOAA, we have 4-6 inches of equivalent water sitting as snow right now in the river valley; some of the northern portions of MN & WI have 10 inches of equivalent water sitting as snow, and there is always a chance for more snow at this time of year - or rain, which melts snow and ice with extreme efficiency. If we have a slow warm up we will be fine, but if the temps go straight to the "normal" range, it will be a rapid warm-up and we got the making for an above average flood this year.
My gut feeling is we will hit "normal" temps before the month is out, and the gates (on the Mississippi dams) will come out of the water in short order... but the problem right now is we have to get warm enough to melt before the water can flow.
