Today's temperature is 55.9 deg F with a windchill of 48.9 deg F. The dew point is aty 41.4 deg F which in turn creates a relative humidity of 58%. The wind is at a blustery 16 mph from the West. The barometer is at 1011.4 mb. This is a large drop form yesterday's barometer meaning that indeed the low pressure system has moving into the region. The skies are 100% covered with stratus clouds. This map from the weather channel shows that yes the front of the low pressure system is currently moving across the Minnesota and Wisconsin region.
I predict more rain and cloudy skies through the night and then some clear skies tomorrow as the high pressure dome moves into the region.
