A strong cold front moved through the state during the early morning hours of the 27th.  Temperatures fell from the 50s into the upper 20s to low 30s within an hour or two.  The cold air was very shallow with warm air continuing to stream into the state.  A large area of thunderstorms developed on the cold side of the cold frontal boundary.  The rain fell into the cold air at the surface, resulting in widespread glazing across much of the southeast half of the Des Moines CWA as temperatures had fallen into the 20s by the time the thunderstorms moved through.  Ice accumulated quite quickly with one quarter inch amounts quite widespread.  Spotty one half inch amounts were reported over parts of central, south central, and southeast Iowa as thunderstorms produced heavier rainfall in those areas.  Scattered power outages were reported across the area and roadways became treacherous due to the icing.  Overall, damage was not all that extensive as the areas that received half inch amounts of ice were relatively small.
