A warm front lifted through Wisconsin the night of the 26th and into the morning of the 27th, leaving a moist and unstable airmass across the region. A cold front in eastern Minnesota pushed east during the afternoon to provide the lift to initiate storms. The storms produced very heavy rain that led to some flooding and also had some damaging winds.
