Record Mississippi River levels on this date in 1965

I’ll get to the Sunday forecast shortly, but I’ll start with a note about river levels. This is the time of year that we’ve seen some very high river levels in the past.

The highest Mississippi River level ever reported at the St. Paul gauge was on April 16, 1965:

The Mississippi River was about 12 feet above flood stage at St. Paul that day. Four of the next five highest levels recorded at St. Paul were between April 13 and April 18.

Currently, the Mississippi River is about 6.4 feet below flood stage at St. Paul:

Harriet Island Regional Park is well above the waters of the Mississippi River right now:

Rain/snow chances

Periods of rain showers are expected in much of northwestern and north-central Minnesota Sunday morning. The showers could mix with a few snow flakes at times.  Rain showers spread to the east and southeast Sunday afternoon. A few showers could arrive in parts of the Twin Cities metro area late Sunday afternoon, with the shower chance lingering into Sunday evening. We could also see a mix of rain showers and a few flakes overnight Sunday night.
