Cool, wet weather on the way
The national corn planting progress was estimated at 28% done as of this past weekend. Looking at the individual states, IL reported 59% of the corn planted and IN reported 46%, while in contrast only 9% of the corn was reported planted in IA, 14% percent planted in NE and 11% in MN.
There are several factors to explain the different rates of planting progress across the midwest including the colder than normal temperatures particularly in the western cornbelt during the month of April with several frosty mornings, and the wide differences in rainfall amounts. The last time so far, that a large part of central IL experienced freezing temperatures was on the 12th of April, 2012. Further west and north however, IA and nearby states experienced subfreezing temperatures on the 17th, on the 20th, 21st, and the 23rd of April.
Another cold high pressure is forecast to move down out of Canada this next weekend and there could be some areas of frost on Sunday or Monday morning again. The cold frosty temperatures probably explain the large differences in planting progress, but it should also be noted there are widespread wet and dry patterns that exist between the eastern and western cornbelt this April.
For example, many central IL and northern IN stations are reporting 50% to 60% of the normal precipitation so far for the month of April or less rainfall. Peoria, IL reports 52%, Springfield, IL, reports 74%, Decatur, IL, 45%, Lafayette, IN, reports 17%, Fort Wayne, IN, reports 18% and Findlay, OH, 32% of normal rainfall. Meanwhile many stations in IA report closer to 100% of normal rainfall for the month of April, including Sioux City, IA, at 107%, Mason City, IA, at 127%, and Waterloo, IA, at 101%, and a little less than normal at Fort Dodge, IA with 76% of normal rainfall.
Heavy rains are forecast this weekend and next week particularly for the western cornbelt. This forecast may keep the lid on planting progress into next week.
