A surface low pressure system slide across southern Iowa on the 27th, eventually turning southeastward into Illinois by late afternoon. Prior to exiting the state, the system did manage to produce light snowfall accumulations of 1 to just over 3 inches across portions of northern Iowa. Quickly on its heels was surface high pressure which centered itself right over Iowa during the late evening and overnight hours of the 27th into the 28th. With clear skies, fresh snow cover for some locations, and cold air having moved in, a freeze warning was issued for the entire county warning area for the overnight hours. By the morning, all but a handful of counties in the southwest managed to drop below freezing for at least a couple of hours. Fortunately for susceptible plant life, a majority of areas avoided prolonged hard freeze temperatures of 28 degrees or less.
