This data presentation utilizes the USDA NASS Quickstats. This presentation is not endorsed nor certified by USDA.

Plot Description:

This autoplot combines the USDA NASS county yield estimates with summarized weather variables from a single weather station. The county that the weather station resides in is used for the comparison.

If you select a statewide areal averaged weather station, you will get the statewide yield estimates and not an individual county. Unfortunately, there is nothing analogous for the climate/crop district weather values as those values are mostly missing within USDA NASS.
