In northwestern sections some locations reported more than 5 inches of snowfall with drifts several feet deep. More than 4 inches was also reported in a small area of Des Moines and Lee counties in the far southeast. At Des Moines 1.3 inches of snow was measured with 1.1 inches of that falling in 24 hours ending on the morning of the 20th, setting a record for the earliest 24 hour snowfall of an inch or more at that location which would stand for nearly a hundred years until October 10, 2009.
