Hydrometeorological Forecast Discussion
NWS North Central River Forecast Center Twin Cities/Chanhassen MN
1013 AM CST Thu Jan 18 2018

Cold temperatures are affecting river gages across the Midwest.
Many automated river gages are reporting erroneous stages.

The risk for freeze-up ice jams is elevated with current cold
temperatures in the Midwest.  River levels may fluctuate three
feet or more in stage due to ice jams and ice activity.

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