I know, our weekend weather has been less than ideal.
A pesky low pressure system over western Wisconsin has been bringing rain to much of Minnesota and Wisconsin Sunday morning. The low pressure system will move slowly away Sunday afternoon, so the rain will gradually lift off to the northeast as we go through the afternoon hours.
Parts of the Twin Cities metro area could see periods of showers linger into early afternoon. There will be periods of showers through much of Sunday afternoon in north-central and northeastern Minnesota as well as northwestern and west-central Wisconsin.
You can hear updated weather information for Minnesota and western Wisconsin on the Minnesota Public Radio News network, and you can see updated weather info on the MPR News live weather blog.
