§ Long-term (last 20+ years) potential yield at each location and surrounding area.
¶ Range of forecasted 2018 potential yields based on average planting date in 2018, indicating yields in the 25th and 75th percentile of the potential yield distribution (associated with respective adverse and favorable weather scenarios during the rest of the season). 
† Probability of obtaining a 2018 yield below (<-10%), near (±10%), and above (>10%) the long-term potential yield at each location.
