Over then next 2 days there is potential for heavy rainfall on
top of frozen ground thereby created much minor flooding
throughout the NCRFC area. This most likely in Illinois,
Wisconsin and Michigan. Depending on the total rainfall
amounts and with the addition of snowmelt there is also
the possibility of more significant flooding in isolated
regions areas.

River forecasts routinely incorporate 24 hours of QPF from
April 1 to September 30 and 48 hours from October 1 to March 31.
