The low moves off to the northeast Sunday afternoon. The Twin Cities metro area could still see scattered showers early in the afternoon, with the best afternoon shower chances in north-central and northeastern Minnesota and northwestern and west-central Wisconsin.

The National Oceanic and Atmospheric Administration’s North American Mesoscale (NAM) forecast model shows the potential precipitation pattern from 7 a.m. to 10 p.m. Sunday:
