The featured time series is daily average soil temperature at a four inch depth from the Ames ISUAG site. The warm weather this April has helped push soil temperatures well above the important 50 degree level, which is roughly how warm the soil needs to be for corn seeds to sprout and grow. The danger can be seen by the climatology value, which is only in the mid 40s. A stretch of cold weather would cool off the soil and hurt a corn seed's development. The actual forecast keeps high temperatures in the 60s, so no worries in sight!
