| Episode Narrative | A high pressure system originating out of Canada settled into the region on April 10-12, 2012 providing clear skies, light winds and cold temperatures. The result was a hard freeze for three nights in a row as minimum temperatures plummeted into the 20s. Most locations saw readings dip into the mid to upper 20s but a few spots reported temperatures in the lower 20s. Stanley, Iowa in Buchanan county was the coldest location with 21 degrees on April 11. After a record warm March which caused vegetation growth to be at least 4 weeks earlier than normal, the cold weather damaged sensitive crops. According to Radio Iowa, widespread frost and freezing temperatures for three nights in a row caused significant damage to crops including apples, grapes and strawberries. At least 50 to 70 percent of these crops were lost especially where temperatures fell to 25 degrees or lower. However, it is unknown the amount of damage in dollar amount. |
| Event Narrative | The COOP observer at La Harpe reported a minimum temperature of 26 degrees. |
