DES MOINES, Iowa (April 20, 2020) – Iowa Secretary of Agriculture Mike Naig today commented on the Iowa Crop Progress and Condition report released by the USDA National Agricultural Statistics Service. The report is released weekly from April through November. 

"With the corn crop insurance planting date behind us, many farmers are looking to get the first seeds in the ground,” said Secretary Naig. “Iowa has been colder than normal, but this week's forecast looks favorable and we should start to see planting progress in some parts of the state.”

Partly cloudy skies and colder than average conditions were reported across Iowa behind the low, with a few snowflakes observed in west-central Iowa. Highs stayed in the 30s statewide with overnight lows in the teens across the northwest to the mid 20s across the rest of Iowa. On Tuesday (14th) temperatures remained unseasonably cold, generally in the mid-30s to low 40s as cloud cover increased. The statewide average high was 39 degrees, 22 degrees below normal.
