On this day in Iowa weather history...
1909: Unseasonably cold air settled across Iowa on October 11-13 causing rain to mix with light snow at times on the 11th and 12th. Most locations only reported a trace of snow but at Boone an observer wrote that "the ground was covered on the evening of the 11th", and at Estherville and Keokuk half an inch of snow was reported. Temperatures fell steadily during this time, bottoming out on the morning of the 13th when Washta reported a low temperature of 10 F. Other lows that morning included 11 F at Pella, 12 F at Inwood and Sheldon, 13 F at Massena and Sioux Center, and 14 F at Audubon and Denison. The hard freeze did severe damage to apple and potato crops and soon afterward many trees shed their leaves which were still green without their usual fall coloring.
