July's above normal temperatures are quickening corn maturity. Forecasts for August and early September see limited potential for precipitation.

A national team led by the University of Nebraska–Lincoln is studying potential links among irrigation, cloud formation and rainfall from a 3,600-square-mile region in southeastern Nebraska.
Why do precipitation maps for the same storms sometimes appear to report different rainfall amounts? How can you determine which one to use when?
When the temperature is consistently above 90°F, many guidelines for alfalfa harvest no longer apply. Rather than using the bloom as a guide, give plants extra time between hot summer harvests to maintain healthy stands.
Figure 1. Planting into cold soil (below 50°F) when cold conditions are expected for the next 48 hours can lead to germination problems and seedlings not emerging or not emerging well. 1a. Corn seedling that started leafing out below ground and now has twisted leaves which will delay or negate normal plant development.. Figures 1b-c. Unemerged seedlings attempting to leaf out belowground. None of the seedlings shown should be counted as a productive plant.
With stormy conditions back in the picture, many growers may be concerned about planting corn into cold, wet soils? By checking weather forecasts and soil temperature at planting (in the field and online) and the cold tolerance of seed, growers can identify 48-hour windows of opportunity for planting.
